Home * Engines * NG-play

a relatively simple, open source chess engine by George Georgopoulos, compliant to the Chess Engine Communication Protocol and written in C. NG-play uses a 10x12 board, and performs a negamax alpha-beta search with iterative deepening, LMR, futility pruning and null move pruning. Evaluation considers material and mobility in a first pass, and focuses on king safety in the middlegame, as well as passed pawn evaluation in a second pass [1]. The engine was written from scratch, the XBoard and opening book code inspired by Tom Kerrigan's TSCP. Bruce Moreland is credited since his programming topics site [2] helped in writing the code to collect the principal variation [3].
