Home * Engines * The Baron

		The Baron, a Chess Engine Communication Protocol compatible chess engine developed by Richard Pijl started in August 2001. Richard's intention was to make a knowledge based engine rather than a fast searcher, with main focus on endgame knowledge. The Baron's search started out to be pretty much brute force, except for null-move pruning, but more recently [1] more extensive use of futility pruning and late move reductions have been implemented. The Baron further applies position learning and has its own type of endgame bitbases [2].
