an UCI compliant open source chess engine by Edoardo Manino, written in Visual Basic, first released in November 2011, in October 2012 with source code [1]. ProChess features a 0x88 board representation, negamax alpha-beta PVS with iterative deepening, transposition table, null move pruning, futility pruning, IID and a capture and promotion only quiescence search. Move ordering considers MVV-LVA, SEE and history heuristic. Only safe checks with positive SEE are extended . A tapered eval interpolates between opening and endgame scores, primarily based on piece-square tables [2].

Tournament Play

ProChess played the IOCSC 2011 and the IOCSC 2012 Italian Open Chess Software Cup, the latter as best Original program, and the CCT15 scoring 50%. At the IGT 2013, ProChess lost the final from Chexa.
