a chess engine by Marco Pagnoncelli, written in C and compliant to the Chess Engine Communication Protocol aka WinBoard.

Description
CyberPagno applies PVS within an iterative deepening framework with aspiration windows [4]. CyberPagno 2.2 and subsequent versions improved due to more effective transposition table structure, and more sophisticated move ordering, selectivity and quiescence search by adding SEE, IID, futility pruning, and LMR. Most recently, the evaluation function was rewritten.
