From Pascutto Gian-Carlo Comm.V.:
Deep Sjeng is a chess program that allows players of any strength to get a quick game going, that adapts to their strength or playing style, and allows them to analyze the games afterwards. It features a world class chess engine, fully adjustable playing strength, a configurable playing style, multiple personalities, and an attractive, modern GUI. It supports Nalimov endgame databases and up to 4 processors (SMP and Dual-Core compatible). Version 2.5 may include unspecified updates, enhancements, or bug fixes.
