Numpty chess,
a free Chess Engine Communication Protocol (aka WinBoard) compatible chess engine by Chris Tatham. Having initially been started in JustBasic 1 it was subsequently translated into, and developed in FreeBASIC. Initially released in December 2005, Numpty has always had an open source code base. It is a comparatively weak engine, having a primary focus of being a reasonable but beatable opponent to casual and club players 2 .
Features
- 10x12 array based board structure with pseudo legal move generation
- Alpha-beta search with iterative deepening and limited quiesence
- Simple evaluation including material, game phase piece-square tables and basic endgame knowledge
