PsycoChess
PsycoChess, (Psyco Chess)
an open source chess engine by Massimo Zizi, written in Java and released in June 2004 under the GPL. PsycoChess applies rotated bitboards, and a 4 ply fixed depth alpha-beta without iterative deepening and quiescence. A transposition table is used a the root only. Instead of negamax or indirect recursion via max and min-routines, a boolean parameter is passed to the direct recursive search whether it is a max or min player [1]. The rudimentary Evaluation considers material, and piece-square tables and some pawn structure terms [2].
