I have discovered some small problems with crafty.
1) If a castling leads to a check, crafty does not output the + after
the move, i.e. O-O is output and not O-O+.
2) Sometimes crafty does not output the right move list when in analyze
mode. Enter crafty and then analyze mode. Type the
moves a3, a6 and Nf3. If you now type history you only get the first
moves. Below is the output:
book 0.0s 29% g6
analyze.Black(1): a6
a6
Black(1): a6
clearing hash tables
time surplus 0.00 time limit 30.00 (3:00)
depth time score variation (1)
4-> 0.29 0.00 2. Nf3 Nc6 3. Nc3 Nf6
5 0.41 0.22 2. Nf3 Nc6 3. Nc3 Nf6 4. e4
5-> 0.99 0.22 2. Nf3 Nc6 3. Nc3 Nf6 4. e4
Nf3 6 0.99 1/19 2. Nf3
White(2): Nf3
analyze.White(2): White(2): Nf3
clearing hash tables
time surplus 0.00 time limit 30.00 (3:00)
depth time score variation (1)
hi 5 0.20 4/19 2. ... d5
Black(1): hi
white black
1 a3 ...
5 1.09 -0.02 2. ... d5 3. e3 Nc6 4. Bd3 Bg4
5-> 1.24 -0.02 2. ... d5 3. e3 Nc6 4. Bd3 Bg4
6 2.28 -0.32 2. ... d5 3. e3 Bf5 4. Be2 e6 5. O-O
Note that before the "hi" is typed, crafty outputs "Black(1): " , but it
should have output "Black(2): ".
3) Finally I have a position where crafty does not find a mate in one.
Is this a bug or is it nullmove related or something ?
The FEN is: 7k/4N3/7K/4N3/8/8/b7/8 w - - 0 5
The mating move is N5g6#. By the way this position arise from a nice
problem with FEN: 6bk/8/3P2K1/4N3/8/8/2r5/1N6 w - - 0 1
I run crafty on a Windows 95 with EGTB, ROCK opening book and 24Mb (5Mb) hash.
Best regards
