H.G. Muller [Fri, 19 Nov 2010 18:27:19 +0000]
Make Spartan Chess primary fairy variant
H.G. Muller [Fri, 19 Nov 2010 18:22:00 +0000]
Change representation of Nutters pieces
The Nutters (officially: 'Nutty Knights') now use Knight-like symbols
for all their knightish pieces: the Unicorn for the Charging Knights
(which is both Knight-like and King-like), the Nightrider for the
Fibnif and the Vortex Chancellor for the Colonel. The Charging Rook is
represented by the promoted Rook symbol.
H.G. Muller [Fri, 19 Nov 2010 17:51:53 +0000]
Let Clobberers use Dragon Horse for Bede
The corner piece of the Clobberers array now is represented by Dragon
Horse rather than Lance, but 'L' is still used for notation (rather than
the default 'I'),for 'Lama'. This requires even FIDE vs Clobberers
to define a -pieceToChar string.
H.G. Muller [Wed, 17 Nov 2010 15:30:57 +0000]
Make undo work in Seirawan Chess
The holdings were not restored before replaying the game. This has now
been moved to InitGame(), which does it based on a gating flag set in
LoadGame() if the variant name is "seirawan".
H.G. Muller [Wed, 17 Nov 2010 15:07:23 +0000]
Account for Elephant and Hawk in Seirawan game stage
The holdings pieces were not counted when initializing R.
H.G. Muller [Wed, 17 Nov 2010 14:43:30 +0000]
Fix the moves of the Colonel in the Nutters army
There was a spurious backward Knight moveon this piece, and some moves
were considered twice.
H.G. Muller [Wed, 17 Nov 2010 14:35:45 +0000]
Suppress bad gatings in variant seirawan
For moves done by the engine, the QS score after gating is compared to
the original score of the move (which did not consider gating), and if
it is much lower, the gating is cancelled.
H.G. Muller [Tue, 16 Nov 2010 11:36:31 +0000]
Implement variant seirawan, and add it
The gating is implemented through a kludge: the search is not aware that
pieces can be gated in, but any move that evacuates the back rank when
there are pieces to be gated available, will gate one (first Hawk, then
Elephant.
H.G. Muller [Tue, 16 Nov 2010 10:15:52 +0000]
Remember promotion char in game history
Undo did not work when there were under-promotions in the game.
H.G. Muller [Fri, 12 Nov 2010 17:29:56 +0000]
Shape up Nutters army
Better piece order
H.G. Muller [Fri, 12 Nov 2010 17:23:09 +0000]
Add Clobberers vs FIDE game definition
H.G. Muller [Fri, 12 Nov 2010 16:41:17 +0000]
Shape up the Clobberers army
The pieces are defined in a better order (for MVV/LVA), and the
Clobberers are made to promote to Archbishop.
H.G. Muller [Sun, 7 Nov 2010 20:51:36 +0000]
Let edit command switch to force mode
Fairy-Max stayed playing the side it was playing before 'edit'. Now it
switches to 'force' mode, so that it won't start to play automatically
on receiving a move after setting up a position.
H.G. Muller [Sun, 7 Nov 2010 20:46:33 +0000]
Properly calculate material eval in asymmetric setups
InitGame assumed that Q=0 in the opening position, but with different
armies this needs not be true. Now it is properly calculated. In the
calculation of R it as also no longer assumed that piece 3 is royal, and
spare Kings are accounted for.
H.G. Muller [Sat, 6 Nov 2010 20:45:16 +0000]
Implement rule change in Spartan Chess
The General now moves as Crowned Rook, and the default promotion piece
has been changed to Warlord. Also adjust some piece values.
H.G. Muller [Sat, 6 Nov 2010 20:39:56 +0000]
Send setup command to GUI
After receiving the variant command for variant fairy, Fairy-Max
responds with a setup command to inform the GUI about the piece names
and opening array of the actually selected variant.
The piece names are defeined (in the format of a WinBoard
-pieceToCharTable string) after the variant name in the fmax.ini file,
separated from it by a '#' sign.
H.G. Muller [Tue, 2 Nov 2010 10:44:24 +0000]
Update docs and version number (4.8P)
H.G. Muller [Tue, 2 Nov 2010 10:38:21 +0000]
Remove stalemate claim from MaxQi
This was code that could not be triggered.
H.G. Muller [Tue, 2 Nov 2010 11:02:49 +0000]
Switch back to absolute royalty when value = -1
This is achieved by simulating we only have one such piece
H.G. Muller [Tue, 2 Nov 2010 10:22:45 +0000]
Limit duple-check rule to piece types above 7
This to allow implementation of normal extinction variants.
The definition of Spartan Chess had to be adapted to maintain the
duple-check rule there, moving the King definition to the end.
The piece ordering was further changed so that the black pieces now
also are ordered low to high, which gives better move ordering in QS,
as Fairy-Max' idea of MVV/LVA orders attacker on piece-type number,
rather than the defined value.
H.G. Muller [Mon, 1 Nov 2010 22:19:25 +0000]
Add FIDE vs Nutty Knights game definition
H.G. Muller [Mon, 1 Nov 2010 21:19:05 +0000]
Allow different default promo piece for black and white
If black lacks the 'Queen' (piece #7) that white has, but has a piece #9
in the initial setup, it will promote to that in stead.
H.G. Muller [Mon, 1 Nov 2010 21:16:58 +0000]
Convert to DOS line ends
H.G. Muller [Mon, 1 Nov 2010 12:54:10 +0000]
Add game definition of Spartan Chess
H.G. Muller [Mon, 1 Nov 2010 12:42:30 +0000]
Switch to extinction-Chess win condition
Normal Chess is of course a form of extinction Chess where you have to
exterminate the King piece type, since you only have a single one.
Royalty is still indicated by negative piece value, bt a win now only
occurs if you capture the last royal piece of its kind, rather than the
first.
The 'duple check' of Spartan Chess is treated as an exception, however:
when there is choice between royal pieces to capture, this is sufficient
for a win.
H.G. Muller [Mon, 1 Nov 2010 12:27:17 +0000]
Keep count of all on-board piece types
The array pl[] is used to keep track of the number of pieces of each
type. It is updated when the piece is captured. For now, it ignores
promotions.
H.G. Muller [Mon, 1 Nov 2010 12:09:34 +0000]
Save total material with setup position
The total-material counter R, which determines the game stage, was not
saved with a setup position, so that 'undo' could mess it up. The piece
counters for each side, in pl[], are now saved in a loop, rather than
just the WHITE and BLACK element, and is extended to 32 elements.
H.G. Muller [Mon, 1 Nov 2010 11:41:36 +0000]
Implement e.p.-less initial double-moves
The leaper bit in the secondary rights (in combination with primary
rights = 4, the double-push code) is used to indicate the e.p. square
should not be set. In this case the secondary hopper bit indicates if
the double push can even be made if the intermediate square is occupied
(to make it a rank-dependent leaper move rather than a true double-
push). In al cases these secondary bits are cleared.
H.G. Muller [Mon, 1 Nov 2010 10:54:08 +0000]
Allow sub-specification of variant fairy
If game definitions in the fmax.ini file now have a name starting with
"fairy/", they are not mentioned in the variants feature, but in stead
the part after the '/' will appear in a combobox engine option for
choosing the actual variant to play when the GUI says "fairy".
H.G. Muller [Mon, 1 Nov 2010 10:18:44 +0000]
Print promotion characterwith move
We cannot rely on the WinBoard default of Queen, as in some variants the
Queen might not participate.
H.G. Muller [Thu, 6 May 2010 14:00:50 +0000]
Fix macro for MaxQi ini-file name to conform to Makefile
It was defined as QINI_file in stead of INI_FILE.
H.G. Muller [Fri, 22 Jan 2010 16:53:54 +0000]
Put all files in tar ball in a directory
The dist target in the Makefile was changed to first copy everything to
temporary directory, and then pack that in a tar ball.
H.G. Muller [Sun, 17 Jan 2010 21:04:24 +0000]
Let Makefile pay attention to $(DESTDIR)
Patch requested by Debian
H.G. Muller [Sun, 17 Jan 2010 20:57:15 +0000]
Delete md5sums with make dist-clean
H.G. Muller [Sun, 17 Jan 2010 20:53:28 +0000]
Rename manual source file
The file fmax.6.pod was renamed to fairymax.pod to automatically produce
proper headers after running pod2man on it, and the Makefile was updated
to accomodate this change.
H.G. Muller [Sun, 17 Jan 2010 14:20:34 +0000]
Remove Shatranj stalemate claim
As the search of Shamax does not distinguish checkmate and stalemate, it
could never be triggered.
H.G. Muller [Sat, 16 Jan 2010 13:48:21 +0000]
Update changelog
H.G. Muller [Sat, 16 Jan 2010 13:26:36 +0000]
Fix eval flip on WB color commands
The differential eval Q was not flipped when the WB-protocol command
black or white did change the side to move.
H.G. Muller [Sat, 16 Jan 2010 13:09:58 +0000]
Fix Shatranj game-end messages
Because stalemate was tested before the conditionally included shatranj
bare-king code, it was not effective. Furthermore, the stalemate code
was still claiming a draw. Now ShaMax has its own stalemate code, put
after the bare-king test.
H.G. Muller [Fri, 15 Jan 2010 21:15:54 +0000]
Use MSDOS line endings in fmax.ini consistently
H.G. Muller [Fri, 15 Jan 2010 21:12:06 +0000]
Change game description af -variant fairy
Use Chess with Different Armies, FIDE army vs. Color-bound Clobberers.
H.G. Muller [Fri, 15 Jan 2010 21:01:58 +0000]
Bugfix on new castling method
Copying the Rook square in stead of growing a Rook was done after the
Rook square had already been cleared. In addition the Rook ended up on
d1 for e1b1 castling. To fix that, the alternated step vector had to be
calculated in advance, before being sure it would be applied, to be
available in the castling code. The variable v is now used as a
temporary for that, as it was available after the score is minimaxed.
H.G. Muller [Fri, 15 Jan 2010 16:32:29 +0000]
Bump version number
H.G. Muller [Fri, 15 Jan 2010 16:30:53 +0000]
Let make dist also create file with md5 sums
H.G. Muller [Fri, 15 Jan 2010 11:28:04 +0000]
Implement variant Makruk
Add Makruk support in the form of 6th-rank promotion (enabled through a
kludge based on the 'Queen' piece value). Add Makruk as new variant to
the fmax.ini file, and mention it in the man page.
H.G. Muller [Fri, 15 Jan 2010 10:19:27 +0000]
Suppress spurious Thinking Output on MakeMove
In the new location the printing of PVs happened for any legal move at
d<1, also when checking legality of an input move. So printing is now
limited to d>0, and to the true search.
H.G. Muller [Fri, 15 Jan 2010 10:05:25 +0000]
Allow castling with any original corner piece
Before, castling was only possible with piece type 6, but this
restrction is now lifted, and castling is accepted if the type of the
piece in the corner corresponds to that specified in the initial setup.
For setup positions the rules for the WB-prtocol edit command are
applied with respect to this setup: a royal piece or a corner piece that
starts in the opening position is assumed to not have moved.
H.G. Muller [Fri, 15 Jan 2010 08:39:16 +0000]
Update description in fmax.ini file
H.G. Muller [Fri, 15 Jan 2010 08:32:25 +0000]
Allow different white and black pieces to use same name
White and black pieces must sometimes be programmed separately, because
they have asymmetric moves (e.g. Pawns), but when they are each other's
mirror imge, we want them to go by the same name. To allow that, the
first piece of any name is now used for white, the last for black.
H.G. Muller [Fri, 15 Jan 2010 06:44:23 +0000]
Fix King name for Knightmate in fmax.ini
Change the letter for the Royal Knight of Knightmate from U to K, to
conform to the XBoard standard piece naming for this variant.
