PsycoChess, (Psyco Chess)
an open source chess engine by Massimo Zizi, written in Java and released in June 2004 under the GPL. It applies rotated bitboards, but pure alpha-beta with transposition table, no iterative deepening and quiescence, but with a constant depth. 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] .
