 * Home * Engines * GES**

David B. Weller's first chess engine, written in C and compliant to the Chess Engine Communication Protocol aka WinBoard, first released in July 2004. GES uses PVS with aspiration, a main transposition table and pawn hash table, verified null move pruning, and a rudimentary SEE. GES' extension policy was to add one ply if any of the conditions met, which were checks, pawns to 2nd/7th rank, mate threats, one replies, and recaptures, and later tried aggregated but fractional extensions without obvious progress.
