a Chess Engine Communication Protocol compatible chess program by Sylvain Renard, competing the 15th World Microcomputer Chess Championship 1997 in Paris, the Aegon Man-Machine Tournaments 1995, 1996 and 1997 [1] and various French Computer Chess Championships and Massy Tournaments, winning the title at the FCCC 1999 tied with Chess Tiger [2].


given in 1997 [3]:

CAPTURE is a "classical" chess program. It uses alpha-beta search (with a zero window), check extensions, null-move, history heuristic at the root of the tree. The program uses hash tables (tested with 64 Mb of RAM but should work with more!). The move generator does not use bit boards. The main chess knowledge of CAPTURE: pawn structures, development and mobility of pieces, piece placement, some endgame knowledge (essentially pawn endgames and mating routines). The value of pieces depends slightly on the number of pawns on the chessboard. The evaluation function is "made by hand" and modified according to positional tests.
