31337 Chess engine
31337 is a winboard compatible chess engine written in Delphi.
Currently the following things are implemented:
-
Iterative deepening
-
Alpha-beta pruning
-
Killer heuristic
-
Static evaluation tables
-
Basic chess rules, including en passent, promotion and castling
-
Instant move when it sees forced mate (still need to add a mate in
x moves/ply notification)
-
Opening book (rather primitive, but it works :)
-
FEN support (for quick debugging :)
-
Hashtables
-
3fold repetition
-
Simple evaluator, it is a bit careless with it's king, and occasionally
throws a winning endgame away :(
The engine runs in the Fritz interface using the winboard plugin.
However, it locks up when used in Chessbase (0.30 build 2001-07-24 and
later).

Uploaded version 0.40, I'm not sure if it's 100% stable, but it fixes
some bugs from 0.30 and has played reasonably ok on FICS/ICC for the past
months. |

Released a new version, some people reported illegal moves being played
on occasion (which was caused by bugs in my movegen, those should be fixed
now) |
