Matant, a WinBoard compatible chess engine by Antoni Szczepański, written in C, and first released in July 2005. Matant played six Polish Computer Chess Championships, from 2002 until 2007. In its logged search statistics, Matant reports nullmove pruning, mate threats, check extensions, single reply extensions, transposition table information, number of nodes of main search and quiescence search, maximum positional score for both sides, and game phases in a 0-13 range from opening to endgame. Based on that information, Matant apparently applies lazy evaluation as well as tapered evaluation. Further, Matant uses Scorpio Bitbases.
