Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19yy name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

I +started to enhance Lasker when I needed a working chess server for a +local school. You can get the original 'lasker' release from +http://chessd.sourceforge.net/ and you can get my enhanced version +from http://chess.samba.org/ + +Here is a list of some of the new features in this version: + + - lots and lots of bugs fixed + - timeseal support added (see timeseal/README for details) + - server configuration via 'aconfig' command instead of config.h + - added multi-part command parsing (commands separated by ';') + - enhanced aliases + - build/install process fixed + - fixed help system + - transparent server reload (upgrade without disturbing connections or games) + + +Installation +------------ + +First you need to configure and compile the chessd server. Do +something like the following: + + cd src + ./configure --prefix=/usr/local + make + +Then to install the server run "make install". That will install a +basic skeleton installation in /usr/local/chessd. + +Setting up +---------- + +Next you will want to launch your chess server using the command: + bin/chessd -f -p 5000 +while in the chessd/ directory. This will launch the chess server +using the skeleton data you installed above. + +I highly recommend creating a separate account on your machine to run +the chess daemon. This user should own all files in the chessd +directory. + +After you launch chessd for the first time you will need to login as +the special user 'admin'. That username will be recognised as the +server administrator and you will be logged in with the rather unusual +combination of a head administrator who is also an unregistered +player. + +The first thing you will want to do as the admin user is create a +proper 'admin' account with a password. Use the command 'addplayer' +while logged in as the admin user to create the admin account. You +will be told the password. Then you should immediately logout and log +back in using the admin password you have just been given. You will +probably want to change this password using the 'asetpass' command. + +You may also find the following commands useful: + ahelp addplayer + ahelp asetpass + ahelp commands + + +Securing your server +-------------------- + +The source code for this chess server has been hacked on by dozens of +people over the years. It almost certainly has exploitable buffer +overruns or other security holes. If you are like me then you won't +like the idea of running an insecure program like that on your server. + +To make it a lot more secure you can choose to run the chess server in +a chroot jail. This makes it much harder for an attacker to gain a +foothold on your server. It won't prevent them from crashing the +chessd process but it will prevent them from gaining access to other +parts of the system. + +To run chessd in a chroot jail you need to do the following: + + 1) chessd needs to be setuid root. I know this sounds bizarre, but + it needs root privileges to use the chroot() system + call. Immediately after the chroot chessd will permanently lose + its root privileges and instead become the user that launched + chessd. To make chessd setuid root do this as root: + chown root chessd + chmod u+s chessd + + 2) pass the command line option -R to tell chessd that it should + chroot to the current directory. So to launch chessd you can use + this: + chessd -p 5000 -T /usr/local/bin/timeseal_decoder -R /usr/local/chessd + + You may also like to look at the start_chessd script in the + scripts directory. This is the script I use to keep chessd + always running on my machine. + +If you do use the -R option then I also recommend that you don't place +any of the chess server binaries (or any other binaries or libraries) +inside the chessd directory. That will increase the security of your +server a little. + + +Email spool +----------- + +This chess server does not send emails directly, instead it puts +outgoing emails in the spool/ directory and waits for some external +program or script to deliver them. I designed it this way as it makes +it possible to send email from a chess server in a chroot jail, and +offers more flexibility in how email is handled (as that tends to vary +a lot between systems). + +If you run sendmail then the sample script in scripts/spool_sendmail +might be good enough. Just run this script at startup and it will send +all spooled mail every minute. + + +Server reload +------------- + +This version of chessd supports reloading the server code without +having to shutdown the server or disturb any games that are in +progress. This allows for on the fly upgrades, hopefully without the +users even noticing that the system is being upgraded. + +In order to support this functionality I had to make the source code +rather more Linux specific than it was previously, but I think that is +worth it for the functionality. It would be possible to port the code +to many other platforms, but I have not yet done so. + +To reload the server use the command 'areload'. You must be at the +ADMIN_GOD admin level to issue this command. + +Updates +------- + +Updates will be available on http://chess.samba.org/ + +You may wish to use the cvs version to enable you to update more +easily. I will only be doing tar ball releases occasionally. + +License +------- + +This chess server release is under the GNU General Public License, +which is the license used by the original chess server written by +Richard Nash. Various parts of the server are under different +licenses, depending on who wrote what part, but I believe that all of +the licenses are compatible with the GPL. + +The reason I chose the GPL for this release is that I don't want this +code to become proprietary again. This has happened at least 3 times +in the past with this source code and while I'm sure there were very +good reasons at the time, it does mean that the freely available chess +servers have not benefited from the considerable development that has +happened over the past seven years. + +I also chose the GPL because it allows me to incorporate source code +from other GPLd projects. This saved me quite a lot of time, and is +sure to be useful again. + + +-------------------------------- +Andrew Tridgell +tridge@chess.samba.org June 2002 +-------------------------------- diff --git a/lasker-2.2.3/bots/CVS/Entries b/lasker-2.2.3/bots/CVS/Entries new file mode 100644 index 0000000..e8df309 --- /dev/null +++ b/lasker-2.2.3/bots/CVS/Entries @@ -0,0 +1 @@ +D/mamer//// diff --git a/lasker-2.2.3/bots/CVS/Repository b/lasker-2.2.3/bots/CVS/Repository new file mode 100644 index 0000000..99f0fee --- /dev/null +++ b/lasker-2.2.3/bots/CVS/Repository @@ -0,0 +1 @@ +lasker/bots diff --git a/lasker-2.2.3/bots/CVS/Root b/lasker-2.2.3/bots/CVS/Root new file mode 100644 index 0000000..c42ba94 --- /dev/null +++ b/lasker-2.2.3/bots/CVS/Root @@ -0,0 +1 @@ +/home/cvs diff --git a/lasker-2.2.3/bots/mamer/CVS/Entries b/lasker-2.2.3/bots/mamer/CVS/Entries new file mode 100644 index 0000000..b3af5b5 --- /dev/null +++ b/lasker-2.2.3/bots/mamer/CVS/Entries @@ -0,0 +1,34 @@ +/Command.cc/1.9/Tue Jul 2 00:05:19 2002// +/Command.hh/1.5/Thu Sep 10 19:58:31 1998// +/CommandEntry.cc/1.15/Tue Jul 2 00:05:19 2002// +/CommandEntry.hh/1.11/Thu Sep 10 19:58:31 1998// +/Game.cc/1.4/Tue Jul 2 00:05:19 2002// +/Game.hh/1.5/Tue Jul 2 00:05:19 2002// +/Makefile/1.8/Fri Sep 11 15:47:50 1998// +/Mamer.cc/1.19/Tue Jul 2 00:05:19 2002// +/Mamer.hh/1.13/Tue Jul 2 00:05:19 2002// +/Player.cc/1.4/Thu Sep 10 19:57:17 1998// +/Player.hh/1.4/Tue Jul 2 00:02:40 2002// +/Storage.cc/1.1/Thu Sep 10 19:57:17 1998// +/Storage.hh/1.1/Thu Sep 10 19:58:41 1998// +/Tourney.cc/1.12/Tue Jul 2 00:02:40 2002// +/Tourney.hh/1.12/Tue Jul 2 00:02:40 2002// +/TourneyParameters.cc/1.2/Thu Sep 10 19:57:17 1998// +/TourneyParameters.hh/1.3/Thu Sep 10 19:58:41 1998// +/TourneyPlayers.cc/1.7/Thu Sep 10 19:57:17 1998// +/TourneyPlayers.hh/1.6/Thu Sep 10 19:58:41 1998// +/User.cc/1.10/Thu Sep 10 19:57:17 1998// +/User.hh/1.8/Thu Sep 10 19:58:41 1998// +/command_list.h/1.2/Wed Oct 8 21:03:08 1997// +/config.h/1.5/Thu Sep 10 19:58:20 1998// +/link.cc/1.5/Thu Sep 10 19:57:17 1998// +/link.hh/1.2/Wed Apr 15 16:56:34 1998// +/linklist.hh/1.3/Thu Sep 10 19:58:41 1998// +/main.cc/1.4/Thu Sep 10 19:57:17 1998// +/mamer.config/1.1/Thu Sep 10 19:59:41 1998// +/types.h/1.11/Thu Sep 10 19:58:20 1998// +D/bin//// +D/data//// +D/help//// +D/logs//// +D/template//// diff --git a/lasker-2.2.3/bots/mamer/CVS/Repository b/lasker-2.2.3/bots/mamer/CVS/Repository new file mode 100644 index 0000000..d93f63a --- /dev/null +++ b/lasker-2.2.3/bots/mamer/CVS/Repository @@ -0,0 +1 @@ +lasker/bots/mamer diff --git a/lasker-2.2.3/bots/mamer/CVS/Root b/lasker-2.2.3/bots/mamer/CVS/Root new file mode 100644 index 0000000..c42ba94 --- /dev/null +++ b/lasker-2.2.3/bots/mamer/CVS/Root @@ -0,0 +1 @@ +/home/cvs diff --git a/lasker-2.2.3/bots/mamer/Command.cc b/lasker-2.2.3/bots/mamer/Command.cc new file mode 100644 index 0000000..62f0b00 --- /dev/null +++ b/lasker-2.2.3/bots/mamer/Command.cc @@ -0,0 +1,156 @@ +//-------------------------------------------------------------------------- +// Command.cc - Source file for the Command class +// +// Matthew E.

With the release of mamer 2.0, much of this document has been +rewritten by toddmf. Send questions, comments, suggestions, etc. to toddmf. + +Introduction and general server considerations +---------------------------------------------- + + Congratulations on becoming a mamer manager! You have earned this position +through your high level of maturity and interest in FICS chess(tournaments in +particular). Less than 1% of FICS users have been given the honor of being a +TM. That being said, being a TM is also a responsibility. It is essential that +you continue to maintain a higher standard of maturity than most users for +several reasons. The most obvious situations are problems in tourneys. Users +often get angry or impatient for several reasons during a tourney. For example: +User has just been given chaos points, user is angry because he was flagged in +a drawn game, user strongly disagrees with mamer policy, etc. In these +situations, it is necessary for you to stay calm, be competent, and keep +channel 49 and/or the tourney under control without reacting too harshly. +Another reason is that TMs are often mistaken for admins, especially by +new/intermediate users. Please kindly help them if possible, but refer them to +an admin if one really is necessary. + +Expectations +------------ + + Apart from staying out of trouble on FICS, the only requirement that you must +meet in order to remain a mamer manager is to meet a monthly quota for tourneys +managed. Currently, it is 5 tourneys per month. This is only a minimum, +though. Feel free to manage as many as you like. This is fun, remember? :) +This quota does not apply to admins, several of whom only manage when there is +a need for a tourney and no other TMs are online. The quota is in place in +order to keep the manager staff active. If you are unable to remain active as +a manager temporarily, message the COO(currently toddmf) and explain why. If +you plan on being inactive for a long period of time(at least 3 months, or +longer than summer break for students), it is probably best if you step down as +TM(if you've done well as a TM you would probably be able to return as TM when +you return to FICS). + +Mamer's user commands +--------------------- + + Before you get to the the details of manager commands and how to manage a +tourney, you should first make sure you are well equipped to deal with users' +questions about how to use mamer. If you are unfamiliar with any of these +commands, you should try them. + + Command Abbrev Level Basic info + --------------------------------------------------------------------- + finger | fi | 0 | Displays the stats for a user. + help | h | 0 | List commands and descripts. + join | j | 0 | Request to enter a tourney. + listmanagers | lm | 0 | Displays the Managers list. + listtourneys | lt | 0 | Displays the tournament list. + listtourneyvars | vars | 0 | Displays the tournament variables. + listtourneygames | games | 0 | Displays the tournament games. + listplayers | lp | 0 | Displays the players in the tourney. + showcommands | sc | 0 | List commands and descripts. + showhelpfile | shf | 0 | Shows a help file. + who | who | 0 | Displays the tournament games. + withdraw | with | 0 | Remove yourself from a tourney. + +User commands notes: + The "finger" command shows your statistics by default. You can see other + players' stats by "mam finger name". + + "help" is the same as "showcommands". To see help files, use "showhelpfile". + + The old commands "grid" and "standings" are now all neatly packaged in the + "who" command. The players are listed in rank order. + + The "upset points" in the "who" listing are temporary points(they are deleted + when the tourney is deleted). They are calculated like this: If you beat a + higher rated player, you get the difference in rating in upset points. If you + draw a higher rated player, you get half the difference in rating points, + rounded down. For example, a 2000 who beats a 2101 gets 101 upset points. If + he had drawn, the 2000 would have gained 50 upset points. Ratings from when + the players join the tourney are used. + + The "Perfrm" (performance rating) in the "who" listing is a measure of what + the player's USCF(and several other similar systems) rating would be if this + was the only tourney he played in. Again, the ratings from when the players + join the tourney are used. Here is the formula: + + Perf. Rating = Avg. opp. rating + 400 * ((wins-losses)/rounds) + + Most commands now require you to specify the tourney number! Remember this + when giving help. + + Players very often ask about how to find out who is in a tourney, how to see + the standings, how to see a grid, how to see which games are in progress, and + how to see tourney variables. It is useful to have an alias for telling 49 + something along the lines of "Please use the commands 'mam games #', + 'mam vars #', and 'mam who #' for information about the tourney." + +Introduction to managing tourneys +--------------------------------- + + The first thing you should do after becoming a manager is to join channel +48. You can ask for the advice of more experienced TMs in the channel if you +run in to any problems while managing. Channel 48 is also used to discuss +other mamer issues, and it is just as often used for friendly chat among TMs. +Here is a tutorial on how to manage a typical tourney. + +The first thing you need to know is that you will be sending a lot of tells to +mamer while managing. To save yourself some typing, you should either use the +server alias "mam"(short for xtell mamer) or create an even shorter alias like +m. In this tutorial, I will use "mam". + + Step 1: Create a tourney + ------------------------ + + To create a new tourney, type "mam create".

If you + did create the tourney successfully, all you need to remember is the tourney + number. In this tutorial, we'll continue managing tourney number 6. + + Step 2: Select the tournament variable settings + ----------------------------------------------- + + Assuming you are now the manager for tourney 6, type "mam vars 6". + You get back a listing of the current tournament variable settings: + +: +: (T)ime: 4 +: (I)ncrement: 0 +: (R)ounds: 0 +: Max (P)layers: 16 +: (M)ode: r (r)ated or (u)nrated +: (S)tyle: s (s)wiss or (r)oundrobin +: (V)ariant: w (w)ild, (r)egular, (b)ug, or (s)uicide +: (W)ild Type: 10 (0), (1), (2), (3), (4), (5), (8), (9)8a, (10)fr +: Rating (L)ow: 0 +: Rating (H)igh: 9999 +: +: Manager: toddmf + + The letters in () refer to the variable shortcut to be used when changing a + value for a variable. Here is what the variables mean: + + Time -- Same as always: minutes to start the game with + Increment -- Same as always: additional seconds per move + Rounds -- Number of rounds in the tourney. If you leave this at 0, + mamer will choose an optimal number of rounds. + Max Players -- The tourney will automatically close and start when this + many players have joined. + Mode -- Will the tourney games be rated or unrated? + Style -- Round Robin(everyone plays everyone) or Swiss System(system + where, generally speaking, players play opponents with the + same score in the tourney each round). + Variant -- What type of game is being played? Regular is used for + blitz, standard, and lightning. + Wild Type -- This only appears when Variant is set to Wild. Use this to + set which wild type will be played. + Rating Low -- Players with a rating lower than this cannot join. + Rating High -- Players with a rating higher than this cannot join. + + You can change these variables before the tourney starts by using "mam stv # + var value". For example, "mam stv 6 t 1" would change the time variable to 1. + Once the tourney has opened, you can only change the Max Players and Style + variants, and once it has closed and started, you cannot change any variables! + + Step 3: Beginning the tournament + -------------------------------- + + After you have set the variables, you need to open the tournament so that + players may join. To do so, type "mam open #" ("mam open 6" in our case). + + At this point, mamer will announce the tourney in channel 49 and with a + cshout. You can duplicate the announcements by using the "mam announce #" + command to announce tourney number #. At the moment, there is no limit on how + often you can announce. I hope not to hear many complaints about mamer making + too many cshouts, so please use announce reasonably(somewhere around once per + 30-60 seconds is reasonable). + + When you have enough players, you can close and start the tournament. To do + so, "mam close #". If you are unable to find enough players(a minimum of 4 is + needed for mamer to run a tourney) in a reasonable amount of time, you should + delete the tourney by using "mam delete #" where # is the tourney number. + + Step 4: Running the tournament itself + ------------------------------------- + + If nobody leaves the tournament, there should be no problems. Mamer should + take care of itself. If someone leaves the tourney or logs off of FICS, you + may have some work to do. After managing several tourneys, you will have a + good sense of how long to wait for someone to return before taking action. + The commands you're going to need are "forfeit" and "setres". "mam forfeit + handle #" forfeits a player from tourney number #. Use the forfeit command if + a player has left, you don't expect him back, and there is at least another + round left in the tourney. "mam setres # white black 1/=/0" sets the result + of white vs black in tourney # to a win for white/draw/win for black. Use + this if you are late in the tourney so that the player doesn't have to forfeit + his previous points. Also use setres if you simply want to keep the tourney + moving but expect the player to be back(this is useful for tourneys at very + fast time controls). + + Step 5: The tournament ends + --------------------------- + + Mamer will usually end the tournament automatically and post the final + results. If it does not, type "mam games #" to see any uncompleted games. + Check if those players are logged in(a fast way to do this is "in handle"), + and use forfeit/setres accordingly. + + If there are any problems with the data of the tourney then "message mlong" + the correct values and let the players know that the results will be + corrected. Points in the tourneys are not recorded; what is important is + wins, losses, and placement in the final tourney standings. + + If you have just managed a scheduled tourney(see "help motd" for a list of + them), please message the COO the names of the winner(s) and anyone else who + may have managed the tourney, so that he can create a news item each week. + Also, please "mam keep # 1" to set tourney #'s keep variable to 1. This + allows people to view the scheduled tourney's standings days after the + tourney. + +Chaos points +------------ + + As a TM, you will soon have the power to penalize tourney abuse by giving +someone chaos points. This is done by typing "mam addchaos handle #", where # +is the number of chaos points(use a negative number to remove chaos points). +When someone has 100 chaos points, mamer will censor him, thus preventing him +from playing in tourneys. Firstly, let's talk about when you should not give +someone chaos points. If you forfeit someone or they withdraw before the +tourney ends, mamer will automatically give that person 10 chaos points per +round missed. Chaos points should be given out for non tourney games, +profanity, and other distractions(such as telling 49 "hi mamer" repeatedly +after being warned about overuse of it). Use good judgement. If a player is +playing a non tourney game that will end in 30 seconds, maybe you should not +act. However, if he is in a standard game and ignores your request to end it +and start the tourney, chaos points are warranted. You should probably give +somewhere between 10 and 20 chaos points per disruption. If you find yourself +wanting to give out less than 10, you should consider giving a warning instead. +If you find yourself wanting to give more than 20, you should probably contact +an admin about the abuse. In any case, whenever you add chaos points, please +send them a message explaining how many points were given, why you did so, +and note that decisions can be appealed to the COO. If you don't send a +message, the player may never knew he did anything wrong, repeat his actions, +and soon find himself censored by mamer. By sending a message, the player has +a better chance of not repeating his actions, and it also necessitates having a +good reason for adding the points. + +Manager commands +---------------- + + Here is a summary of all the manager commands. + +: addchaos | ac | 25 | Adds (or subs) chaos points. +: announce | ann | 10 | Announce the tournament to the working + channel. +: addtotourney | att | 25 | Add a user to a tourney. +: create | cr | 10 | Creates a new tournament. +: close | cl | 10 | Closes and starts a tournament. +: delete | del | 10 | Deletes a tournament. +: forfeit | fo | 10 | Remove a user from a tourney. +: keep | k | 25 | Keep a tourney in memory. +: loadedusers | lu | 25 | Displays the loaded users. +: messman | mm | 50 | Message all of the Managers. +: open | ot | 10 | Opens the tournament to players. +: setinfo | si | 100 | Set a user's finger info. +: setmanagerlevel | sml | 50 | Sets manager's level. +: setres | sr | 10 | Sets the result of a game. +: setstat | ss | 50 | Sets a specific finger stat. +: settourneyvar | stv | 10 | Sets a Tourney's Variables. +: shutdown | sd | 50 | Shuts down Mamer. + +All of the level 10 and 25 commands have been covered except for +"addtotourney" and "loadedusers". "addtotourney player #" forces player to join +tourney number #. This is useful for players who want to play in a tourney +that is about to close but can't figure out how to join the first time. If you +need to use this, please try to tell the person how to join future tournaments +so that he doesn't rely on the manager to use addtotourney. It is also useful +to create test tournaments, but aside from mlong testing code, there is rarely +a need for that. "loadedusers" is simply a list of players in mamer's +"memory"; players who have told mamer something recently. The only practical +application for most managers that I can think of is trying to check if a new +mamer player having trouble is even getting as far as telling mamer something. +A note on "delete": Tourneys that aren't "kept"(using keep) are automatically +deleted after two hours. Please don't delete them before this unless you +either want to abort a tourney in progress or open or the tourney list is +getting very cluttered with many fast(ie 1 0, 0 1 suicide) tourneys. Keeping +tourney standings available for some time after the tourney ends was a feature +requested by many users, so please don't negate it by deleting the tourneys +prematurely. + + + +Historical information about mamer +---------------------------------- + + Users sometimes ask about this information. You may also find it +interesting. The following is a cleaned up and up-to-date version of mamer +1.x's "mam help about". + + "Mamer is an automated tournament director for use on FICS only. + Fred Baumgarten originally wrote this code because there was a need and + Chevrier Joel, the creator of Tomato(another TD program), would not + share the code.

Plus the -r- for the + differentiation between mame (Fred's) code and mamer (mlong's) code. + + Fred's words follow: The intention to write this tournament director + program came out of the need to have such a program.

The original Forsyth standard +has been slightly extended for use with chess software by Steven Edwards with +assistance from commentators on the Internet. This new standard, FEN, was +first implemented in Edwards' SAN Kit. + +16.1.2: Uses for a position notation + +Having a standard position notation is particularly important for chess +programmers as it allows them to share position databases. For example, +there exist standard position notation databases with many of the classical +benchmark tests for chessplaying programs, and by using a common position +notation format many hours of tedious data entry can be saved. Additionally, +a position notation can be useful for page layout programs and for confirming +position status for e-mail competition. + +Many interesting chess problem sets represented using FEN can be found at the +chess.uoknor.edu ftp site in the directory pub/chess/SAN_testsuites. + + +16.1.3: Data fields + +FEN specifies the piece placement, the active color, the castling +availability, the en passant target square, the halfmove clock, and the +fullmove number. These can all fit on a single text line in an easily +read format. The length of a FEN position description varies somewhat +according to the position. In some cases, the description could be eighty +or more characters in length and so may not fit conveniently on some +displays. However, these positions aren't too common. + +A FEN description has six fields. Each field is composed only of non-blank +printing ASCII characters. Adjacent fields are separated by a single ASCII +space character. + + +16.1.3.1: Piece placement data + +The first field represents the placement of the pieces on the board. The +board contents are specified starting with the eighth rank and ending with +the first rank. For each rank, the squares are specified from file a to +file h. White pieces are identified by uppercase SAN piece letters +("PNBRQK") and black pieces are identified by lowercase SAN piece letters +("pnbrqk"). Empty squares are represented by the digits one through eight; +the digit used represents the count of contiguous empty squares along a +rank. A solidus character "/" is used to separate data of adjacent ranks. + + +16.1.3.2: Active color + +The second field represents the active color. A lower case "w" is used if +White is to move; a lower case "b" is used if Black is the active player. + + +16.1.3.3: Castling availability + +The third field represents castling availability. This indicates potential +future castling that may of may not be possible at the moment due to blocking +pieces or enemy attacks. If there is no castling availability for either +side, the single character symbol "-" is used. Otherwise, a combination of +from one to four characters are present. If White has kingside castling +availability, the uppercase letter "K" appears. If White has queenside +castling availability, the uppercase letter "Q" appears. If Black has +kingside castling availability, the lowercase letter "k" appears. If +Black has queenside castling availability, then the lowercase letter "q" +appears. Those letters which appear will be ordered first uppercase before +lowercase and second kingside before queenside. There is no white space +between the letters. + + +16.1.3.4: En passant target square + +The fourth field is the en passant target square. If there is no en passant +target square then the single character symbol "-" appears. If there is an +en passant target square then is represented by a lowercase file character +immediately followed by a rank digit. Obviously, the rank digit will be "3" +following a white pawn double advance (Black is the active color) or else be +the digit "6" after a black pawn double advance (White being the active +color). + +An en passant target square is given if and only if the last move was a pawn +advance of two squares. Therefore, an en passant target square field may have +a square name even if there is no pawn of the opposing side that may +immediately execute the en passant capture. + + +16.1.3.5: Halfmove clock + +The fifth field is a nonnegative integer representing the halfmove clock. +This number is the count of halfmoves (or ply) since the last pawn advance +or capturing move. This value is used for the fifty move draw rule. + + +16.1.3.6: Fullmove number + +The sixth and last field is a positive integer that gives the fullmove number. +This will have the value "1" for the first move of a game for both White and +Black. It is incremented by one immediately after each move by Black. + + +16.1.4: Examples + +Here's the FEN for the starting position: + +rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1 + +And after the move 1. e4: + +rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1 + +And then after 1. ... c5: + +rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq c6 0 2 + +And then after 2.

The difference in the two procedures concerns the start position of the +board in bsetup mode: empty board versus a board position. + + (a) FROM SCRATCH -- When nothing else is active (that is, you are not +playing or examining another game), type either "bsetup" or "examine setup". +The board will be totally empty when you enter bsetup mode; you will have to +place all of the pieces where you want to have them. + + (b) FROM WITHIN EXAMINE MODE -- Typing "bsetup" during examine mode (namely +while you are examining a game) places you in "examine bsetup" mode. The move +list is cleared and a new move list will be established. However, the current +board position will be used as the starting board position; you can then +modify that position and arrange the pieces to be where you want them to be. + +USING BSETUP MODE +---------------- + + There are several commands you can use in order to create a board position +and designate which side is going to move next. + + BSETUP CLEAR -- Typing the command "bsetup clear" will give you a new, +blank, empty board. + + BSETUP START -- Typing the command "bsetup start" will give you the regular +starting position for a game of chess. + + BSETUP board_category board -- You can load a non-standard board position if +you want. The chess server has several non-standard boards. They can be +listed by using the "board" command. For example, "boards openings" will list +the various openings you can start a game from and "boards wild" will list +"wild" opening positions. Note: you must first be in bsetup mode in order to +create a given board position. + To create a suicide game, type "bsetup suicide". + + BESETUP FEN position -- You can also set up complete board positions by +supplying a FEN position. For example: + + bsetup fen rnbqkbnr/pppppppp/8/8/8/3P4/PPP1PPPP/RNBQKBNR + +You have to indicate the pieces and blank squares on each rank of the chess +board, starting with rank 8 (Black's back rank) and going from the a-file to +the h-file. The '/' mark divides one rank of pieces from another. Letters in +CAPS mean a White piece (such as 'K' for White King); small letters mean a +Black piece (such as 'k' for Black King). The numbers (such as 1, 3, 4 and 8) +refer to the number of *consecutive* blank squares. For example, the fen +position given above is the one that occurs when White opens the game with +Pd3. NOTE: You just give the board position, not which side is to move; +use "tomove" to modify whose move it is. + + Placing pieces -- There are two formats for placing pieces: case sensitive +and designate color.

The +possible 'rights' are: + + none (no castling) + kside (kingside only) + qside (queenside only) + both (both sides) + +When you load a board using bsetup the rights are set up automatically. On a +cleared board both player's rights are set to 'none'. Therefore if you use a +ready made board and move the rooks and kings around, you will need to set the +appropriate castling rights. Castling rights are validated when you exit +bsetup; if the rights are invalid, you will receive an error message. + + BSETUP EPPOS -- You can indicate whether an "en passant" capture is +possible, as if a pawn had just been advanced two squares.

Instead of two +separate ratings formulas for the two categories, there is now a single +formula incorporating the two ratings and the two RD's to find the ratings +changes for you and your opponent after a game. + +What RD represents +------------------ + +The Ratings Deviation is used to measure how much a player's current rating +should be trusted. A high RD indicates that the player may not be competing +frequently or that the player has not played very many games yet at the +current rating level. A low RD indicates that the player's rating is fairly +well established. This is described in more detail below under "RD +Interpretation". + +How RD Affects Ratings Changes +------------------------------ + +In general, if your RD is high, then your rating will change a lot each time +you play. As it gets smaller, the ratings change per game will go down. +However, your opponent's RD will have the opposite effect, to a smaller +extent: if his RD is high, then your ratings change will be somewhat smaller +than it would be otherwise. + +A further use of RD's: +---------------------- + +Vek asked Mark Glickman the following: + +> Given player one with rating r1, error s1, +> and player two with r2 and s2, do you have a formula for the probability +> that player 1's "true" rating is greater than player 2's ? + +Mark said: + + Yes - it's: + + 1/(1 + 10^(-(r1-r2)f(sqrt(s1^2 + s2^2))/400) ) + + where f(s) is [the function applied to RD in Step 2 below]. + +How RD is Updated +----------------- + +In this system, the RD will decrease somewhat each time you play a game, +because when you play more games there is a stronger basis for concluding what +your rating should be. However, if you go for a long time without playing any +games, your RD will increase to reflect the increased uncertainty in your +rating due to the passage of time. Also, your RD will decrease more if your +opponent's rating is similar to yours, and decrease less your opponent's +rating is much different. + +Why Ratings Changes Aren't Balanced +----------------------------------- + +In the other system, except for provisional games, the ratings changes for the +two players in a game would balance each other out - if A wins 16 points, B +loses 16 points. That is not the case with this system. Here is the +explanation I received from Mark Glickman: + + The system does not conserve rating points - and with good + reason! Suppose two players both have ratings of 1700, + except one has not played in awhile and the other playing + constantly. In the former case, the player's rating is not + a reliable measure while in the latter case the rating is a fairly + reliable measure. Let's say the player with the uncertain rating + defeats the player with the precisely measured rating. + Then I would claim that the player with the imprecisely + measured rating should have his rating increase a fair + amount (because we have learned something informative from + defeating a player with a precisely measured ability) and + the player with the precise rating should have his rating + decrease by a very small amount (because losing to a player + with an imprecise rating contains little information). + That's the intuitive gist of my extension to the Elo system. + + On average, the system will stay roughly constant (by the + law of large numbers). In other words, the above scenario + in the long run should occur just as often with the + imprecisely rated player losing. + +Mathematical Interpretation of RD +--------------------------------- + +Direct from Mark Glickman: + +Each player can be characterized as having a true (but unknown) rating that +may be thought of as the player's average ability. We never get to know that +value, partly because we only observe a finite number of games, but also +because that true rating changes over time as a player's ability changes. But +we can *estimate* the unknown rating. Rather than restrict oneself to a +single estimate of the true rating, we can describe our estimate as an +*interval* of plausible values. The interval is wider if we are less sure +about the player's unknown true rating, and the interval is narrower if we are +more sure about the unknown rating. The RD quantifies the uncertainty in +terms of probability: + +The interval formed by Current rating +/- RD contains your true rating with +probability of about 0.67. + +The interval formed by Current rating +/- 2 * RD contains your true rating +with probability of about 0.95. + +The interval formed by Current rating +/- 3 * RD contains your true rating +with probability of about 0.997. + +For those of you who know something about statistics, these are not confidence +intervals, but are called "central posterior intervals" because the derivation +came from a "Bayesian" analysis of the problem. + +These numbers are found from the cumulative distribution function of the +normal distribution with mean = current rating, and standard deviation = RD. +For example, CDF[ N[1600,50], 1550 ] = .159 approximately (that's shorthand +Mathematica notation.) + +The Formulas +------------ + +Algorithm to calculate ratings change for a game against a given opponent: + +Step 1. Before a game, calculate initial rating and RD for each player. + + a) If no games yet, initial rating assumed to be 1720. + Otherwise, use existing rating. + (The 1720 is not printed out, however.) + + b) If no RD yet, initial RD assumed to be 350 if you have no games, + or 70 if your rating is carried over from ICC. + Otherwise, calculate new RD, based on the RD that was obtained + after the most recent game played, and on the amount of time (t) that + has passed since that game, as follows: + + RD' = Sqrt(RD^2 + c log(1+t)) + + where c is a numerical constant chosen so that predictions made + according to the ratings from this system will be approximately + optimal. + +Step 2. Calculate the "attenuating factor" due to your OPPONENT's RD, + for use in later steps. + + f = 1/Sqrt(1 + p RD^2) + + Here p is the mathematical constant 3 (ln 10)^2 + ------------- + Pi^2 400^2 . + + Note that this is between 0 and 1 - if RD is very big, + then f will be closer to 0. + +Step 3. r1 <- your rating, + r2 <- opponent's rating, + + 1 + E <- ---------------------- + -(r1-r2)*f/400 <- it has f(RD) in it! + 1 + 10 + + This quantity E seems to be treated kind of like a probability. + +Step 4. K = q*f + -------------------------------------- + 1/(RD)^2 + q^2 * f^2 * E * (1-E) + + where q is a mathematical constant: q = (ln 10)/400. + +Step 5. This is the K factor for the game, so + + Your new rating = (pregame rating) + K * (w - E) + + where w is 1 for a win, .5 for a draw, and 0 for a loss. + +Step 6. Your new RD is calculated as + + RD' = 1 + ------------------------------------------------- + Sqrt( 1/(RD)^2 + q^2 * f^2 * E * (1-E) ) . + +The same steps are done for your opponent. + +Further information +------------------- + +A PostScript file containing Mark Glickman's paper discussing this ratings +system may be obtained via ftp. The ftp site is hustat.harvard.edu, the +directory is /pub/glickman, and the file is called "glicko.ps". It is +available at http://hustat.harvard.edu/pub/glickman/glicko.ps. + +Credits +------- + +The Glicko Ratings System was invented by Mark Glickman, Ph.D. who is +currently at the Harvard Statistics Department, and who is bound for Boston +University. + +Vek and Hawk programmed and debugged the new ratings calculations (we may +still be debugging it).

It is also possible to have a team playing against one person or +a computer. The procedures are simple: (a) set up the teams, (b) appoint one +person from each team as captain, (c) have the two captains match each other +using very long time controls, usually unrated, (d) have two separate channels +for the teams to use for their consultations, (e) have team members observe +the game and consult about moves, (f) have the captain play the move for +his/her team ... and play continues along those lines. + + To start a team game, it is best to have the players use three channels. At +the moment Channels 20, 21 and 22 are primarily for this purpose. To start +with, all the participants turn on one channel (Channel 20) to enable +communication about team formation. The other two channels are for the two +teams. Players of one team turn on the their channel but not the other. Then +the players on each team select a captain. + + Actually, there are many ways to form teams. One way is to let the players +join a channel randomly, another is to agree to two captains first and let +them pick their teams in turn. There is no set rule that must be followed. + + A game is started by the two captains playing each other. Then every +participant observes that game. Players can suggest moves using the +appropriate channels. They can adopt a democracy and vote before making +moves, or they can opt for dictatorship where the captain can decide on the +move, taking advice from the think tank. Any form of decision making is +possible, provided the team has agreed to it beforehand. + + Typically, it takes much longer to play a team game than a game between +individuals, because a lot of discussion is going on. Hence a longer time +control and longer increment are recommended. Several minutes per move is not +uncommon -- and even that time can go quickly. + + +WHY TEAM GAMES? + + Playing team games is a good way to learn because you are involved in a +position and can hear different views on it.

This +help file is intended solely as a public service to FICS users and to +promote chess. The text was written by FICS users and sanctioned by USCF. +Neither USCF or FICS take any responsibility for the accuracy of the +information contained in this file. + +--> What is USCF? + + USCF stands for the United States Chess Federation. USCF is the +national chess organization for the United States. Its purpose is to +promote chess (see the USCF Mission Statement in another FICS help file, +"uscf_mis"). USCF sponsors various kinds of chess tournaments, promotes +chess in public schools and prisons, represents US interests in +international chess organizations, and offers discounts on chess books and +equipment. USCF is composed of over 82,000 individual members and 2100 +local and state organizations (known as "affiliates"). + +--> Are there other national chess organizations? + + Yes. USCF is the main organization for over-the-board (OTB) play. +They also sponsor correspondence ("postal") chess and Quick Chess (games +with faster time controls) but other organizations have national +importance in these two areas as well. Information about these other +organizations may be placed on FICS at a later date. + +--> What are the benefits for joining USCF? + + Well, every member has a different reason for joining. The benefits +of membership include: + + * Chance to play in numerous chess tournaments and have national + ratings in OTB and postal chess + * Cash prizes in tournaments + * A monthly magazine, "Chess Life" ("SchoolMates" for younger + members). + * Discounts for chess equipment and books. + +--> Tell me about the tournaments. + + There are two main groups: Over-the-board (OTB) and Postal. In OTB +tournaments you play against other opponents face-to-face. In Postal +tournaments you play by mail and exchange moves, usually on postcards. +Membership is necessary to play in a USCF tournament (there are some +exceptions, but these are rare) and entry fees are charged. A complete +listing of upcoming OTB tournaments all across the United States should be +available on FICS sometime in July. + +--> What are OTB tournaments like? + + Most tournaments take one or two days over the weekend for maybe half +a dozen games, though major national tournaments may last a week or two +and involve many games. A tournament may have anywhere from a dozen to +600 or even a thousand players. + Tournaments generally have different playing "sections" or groups of +players based on their national ratings. You only play opponents within +your own section. For example, a large tournament might have these five +sections: Open, U2000, U1600, U1200, and Scholastic. Any USCF member can +play in the Open section, only those with a USCF rating under 2000 can +play in U2000, only those below 1600 can play in the U1600 section, only +those below 1200 can play in U1200 and only high school or younger +students can play in the Scholastic. (A high school student with a USCF +rating of 1300, for example, could choose to play in the Open, U2000, +U1600 or Scholastic sections, but not in U1200.) The different sections +allow players of similar strength to compete for prizes. + Tournament games can last anywhere from one or two hours up to four or +five hours, depending on the time control of the tournament. There are +some Quick Chess tournaments with time controls of only 10 or 30 minutes +per player per game. Tournament time controls are very different than +those used on FICS, so learn the details before playing in a tournament. + Tournaments generally offer cash prizes (!!), with the exception being +the Scholastic tournaments which prefer to give out trophies instead. +Most tournaments offer prizes within each section (1st, 2nd and 3rd for +example) as well as other prizes by ratings categories (for example, the +U2000 section may have a prize for the best scoring U1800 player). + Chess tournaments, organized by the local USCF affiliates (especially +state organizations and clubs) are held weekly all across the United +States. Each tournament varies considerably in style, size, prize fund +and difficulty. Information about USCF sanctioned tournaments is printed +monthly in "Chess Life." We also hope to make such information available +on FICS. We suggest you visit a tournament in your local area and catch +the excitement! + +--> What if I want to play in an OTB tournament but never have before? + + If you're unsure how tournaments run, it may be helpful to visit one +or two before playing. Almost all tournaments allow and encourage +spectators. + You need to become aware of tournament rules and etiquette. If you +are in a tournament you will need to know when the rounds start, where the +pairings (lists of who plays who) are posted, how to find your opponent, +where to mark the result of your game, what the time controls are, how to +use a chess clock, how to take notation (it is usually required to record +the moves of your games), etc. + Most tournaments require that you bring your own equipment, but don't +worry if you don't have a regulation set and clock. Most of your +opponents will, and there should be unused sets you can borrow any given +round. If you decide to play in more tournaments, you really should +acquire regulation equipment. + All of this can seem very intimidating to a new player, but if you +show up early, you should have plenty of time to ask the tournament +director, or other players, to explain the whole process. It may be +helpful to obtain a copy of the US Chess Federation's Official Rules of +Chess (4th ed) (available from USCF). + For your first tournament, either mail your entry fee in advance or +pay it in person at the tournament site. In either case, get there early +to familiarize yourself with the rooms, the tournament organizers, and +have a chance to ask questions. + Lastly, remember to just have fun and play some good chess. Most +people do not score very well in their first tournament, but some do win +prizes (larger tournaments generally offer a few prizes for unrated +players). + +--> What's postal chess all about? + + Basically, you play by mail. Your opponent could be from anywhere in +the United States, or even overseas. Generally, you play against +opponents in a small section (4-7 players) with roughly your same level of +ability, though there are also Open tournaments. Each player is required +to make a certain number of moves in a 30-day period (not including the +time it takes for the mail to get through). In examining your next move, +you may consult with books and articles and take notes, but you may not +have computers or humans analyze your games while they are in progress. +Each game may take as long as a year, sometimes longer, but you play +several games simultaneously. You can even have rated matches against +opponents of your own choosing. Some tournaments offer cash prizes; +others offer certificates to the section winners. Information about +postal chess is given each month in "Chess Life." + Many people who are too busy to play OTB tournaments regularly, or +even at all, find that postal chess matches their schedules perfectly. +They can analyze moves during lunch, in the evenings, stalled on the +highway during rush hour, or whenever they have a few minutes free. The +time controls mean a move need not be sent off the day after it is +received, and the players can therefore analyze positions at their +leisure. + +--> Tell me more about "Chess Life"? + + "Chess Life" is USCF's official magazine. It has numerous articles +for players of all abilities, quizzes, ways to test your abilities, +annotated games from recent tournaments across the world, stories on chess +personalities and chess-related news. "Chess Life" prints advance +information on many upcoming chess tournaments in the US as well as postal +chess. It also has catalog supplements several times each year with +information on discounts on chess-related products, including books, +pieces, boards, computers and computer software. Companies selling chess +productes often advertise in "Chess Life" as well. + +--> Tell me more about the affiliates? + + An affiliate is simply a local chess club associated with USCF. +Almost every major city in the United States has an affiliate. Many +universities and other organizations sponsor one as well. Currently there +are just over 2000 affiliates scattered across the nation. + Each club is different, but most generally hold informal meetings a +few times per month, where the club members can get together and play +games, discuss openings, study grandmaster games, eat doughnuts, or +whatever. Clubs are a great way to become involved in chess, and you +normally do not need a USCF membership to join one. + Affiliates often sponsor USCF tournaments, some of which are open only +to the club's members. This depends on each individual affiliate, though. + You can write to USCF at the address below and request a list of +affiliates in your area. + +--> Where do I get more information on USCF? + + Well, "Dogma" on FICS would be more than willing to talk to you about +USCF and playing in a tournament. There are other USCFers on FICS, too, +and you can ask them for their opinions. You can also go directy to the +source and call USCF at ... 1-800-388-KING ... and ask them to send you +membership information, etc. + USCF provides free pamphlets on a variety of subjects, available on +request. These include, but are not limited to, pamphlets describing the +rules, how to take notation, what constitutes official equipment, etc. +Call or write USCF for more information. + +--> How do I become a USCF member? + + There are several ways. You can join at virtually any tournament, +call the above phone number and pay with a credit card, or send your +membership fee directly to USCF at: + 186 Route 9W + New Windsor, NY 12553 + It may be possible to obtain a slight discount by buying your USCF +membership through an affiliate, or as part of tournament registration +fees; however, this depends on each individual affiliate and tournament. + +--> What is the membership fee? + + The regular, one year membership fee is $40, of which $21 is the +subscription to "Chess Life". Youth memberships (age 19 and under) cost +$15 for one year. Senior memberships (65 and older) are $30 per year. + Scholastic memberships cost $10 per year (generally for elementary +students, but available for age 19 and under). A scholastic membership is not +necessary to play in scholastic tournaments; a youth membership would work +just as well. However, Scholastic membership receive "School Mates", a +bi-monthly magazine for the beginning player, rather than the monthly "Chess +Life". + All of the above membership types receive full membership benefits, +including "Chess Life". Again, the major difference between "Youth" members +and "Scholastic" members is that youth members receive "Chess Life" while +scholastic members receive "School Mates". + Discounts are available for junior, family, blind, and prison memberships. +Discounts are also given for longer memberships (for example a two-year +membership); life memberships are also available. + +--> Is USCF membership worth it? + + If you are an avid chess player who wants to play in tournaments and +have national ratings for OTB and/or postal chess, wants to keep up on the +chess scene, or just wants to help promote chess in the United States, the +answer is ... YES!!! Whether you have time for tournament chess, postal +or both, a membership in USCF helps make you a stronger chess player while +also bringing you into contact with other chess players world-wide. You +can play chess all your life, with family, friends, and fellow tournament +players. Chess is a sport that can give you lifelong satisfaction, and +USCF gives you a great opportunity to learn, play, and make new friends +along the way. :) + diff --git a/lasker-2.2.3/data/help/variables b/lasker-2.2.3/data/help/variables new file mode 100755 index 0000000..75514c8 --- /dev/null +++ b/lasker-2.2.3/data/help/variables @@ -0,0 +1,85 @@ + +variables + +Usage: variables [user] + + This command will display the variables of the given user.

The pieces are placed on their 8th rank rather than the 1st rank. +When the game starts, it will look like the board is upside down, with White's +pieces starting on Black's side of the board, and vice versa.

track of players time usage. + +Unlike previous chess servers that had to have the timeseal code built +in in this server uses a small external timeseal_decoder process whose +sole purpose is to decode the timeseal protocol. You can enable this +process (and thus enable timeseal support) using the -T option to +chessd. + +The reasons I designed it this way are: + + - it keeps the timeseal protocol secret, and the protocol relies + on its secrecy to prevent cheating + - it allows me to use GPLd code in the chess server while not + distributing the timeseal decoder source code + + +Using timeseal +-------------- + +To use timeseal in your chess server just pass the location of your +timeseal_decoder binary to the -T option. For example: + + bin/chessd -T bin/timeseal_decoder -p 5000 + +If you also use the -R option to setup a secure chroot jail for your +chess server then you must pass the -T option before the -R option.
