Go up one level in this thread


Thanks again to Stephen Edwards for correcting the syntax of the epd.
Here I hope is the corrected version.

8/7p/R7/7k/8/p5K1/8/r7 b - - am a2;
Q6n/8/8/8/8/6K1/pk6/8 w - - am Qxh8;
8/1Q5n/8/8/8/2p5/7K/2k5 w - - am Qxh7;
1k6/1b6/p1p3p1/Pp1p1p1p/1P1P3P/5PP1/2PN4/5K2 w - - am f4
8/5p2/p3p1p1/1pbkP2p/5P1P/1P4P1/P3KB2/8 w - - am Bxc5;
1r6/5k2/p4p1K/5R2/7P/8/6P1/8 w - - am Kh5;
8/6p1/1p5p/1R2k3/4p3/1P2P3/1K4PP/3r4 b - - am Rd5;
8/8/6p1/3Pkp2/4P3/2K5/6P1/n7 w - - am exf5; bm d6;
8/8/6p1/3PkP2/8/2K5/6P1/n7 b - - am gxf5; bm Kxf5;


Here are the results of Rebel8.

Pos	Rebel8 Default	Rebel8.4G

1	>15:00		>15:00
2	3:50		0:28
3	4:47		4:24
4	0:05		0:50
5	>15:00		>15:00
6	2:10		1:37
7	>15:00		13:24
8	3:00		5:30
9	>15:00		1:12

Rebel8.4G is sel=4 with aggressive style
Machine is a K6-233 60mb hash

Position 8 and 9 are from the same game. It appears
Rebel default is playing d6 in #8 for the wrong reason
as it cannot find the correct followup from #9.

I'd like to see a program have some code for position #1.
Some sort of penalty for advancing the rook pawn to the seventh rank
when no immediate material gain is in site. This is a very common occurance
in endgames.

As posted earlier positions 2 and 3 were found immediately by CM4000.
Do other programs include knowledge for these two basic endings?
