Home * Engines * SnailChess

an experimental WinBoard compliant chess engine by Rasjid Chan with the fame of a slow searcher, written in C, first released in November 1999. SnailChess started as plain alpha-beta searcher, SnailChess 1.07 used NegaScout with transposition table and null move pruning [1], an intermediate SnailSCP was a partial clone of TSCP [2].

The last public SnailChess 4.013 was released in June 2002 [3]. Then SnailChess became a testbed for various board representations and move generation techniques, using incremental updated attack tables and various bitboard methods such as rotated and magic bitboards, and applied an iterative search with a stack of structs [4].
