Yesterday, my engine Alice achieved its first draw against GnuChess. The game
was played at 40 moves/5 min on an Athlon 1GHz, with pondering off.
Alice doesn't have an opening book. It uses a simple evaluation, including
material, centralization, and some development and pawn structure terms. Its
transposition table contains 2^17 entries. At this time control, it reaches
about 5 plies in the middle game.
After some tactical complications (or blunders on the side of GnuChess), Alice
reaches a KRRKR endgame. It thinks that King centralization is bad (even in the
endgame) and thus keeps the white King nicely restricted to the center of the
board, while keeping its own king in the corner. Thus, after the 62nd move,
nothing happens anymore.
After this game, I started a 10-game match at the same time control. Result:
Gnuchess 10, Alice 0. Hence this game is not typical, but it is a start :)
I think about using ChessMaster personalities as sparring partners. (First
experiments show a rating of ~1600.) Does anybody have experience with this? Or
some reason why this is not a good idea?
Cheers,
Sven.
