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.

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.

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.

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.

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.

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.

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.
