Home * Engines * The Baron

Barony of Breda, the home of The Baron [1]

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 [2] 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 [3].

So far, The Baron participated at six World Computer Chess Championships, the WCCC 2005, WCCC 2007, WCCC 2008, WCCC 2009, WCCC 2011, and the WCCC 2015, and various over the board and online tournaments, such as the Dutch Open Computer Chess Championship, International CSVN Tournament, International Paderborn Computer Chess Championship, CCT Tournaments, and the The Chess Programmers Tournament organized by Richard Pijl himself. Opening book authors were Carlos Pesce [6], Arturo Ochoa [7] [8], and Sebastian Böhme [9]. In May 2014, The Baron won the PT 46, in June 2015, the PT 48, and in November 2017 the PT 52. At the IGT 2016 in Rome, The Baron came in third behind winner Chiron and Booot.


A version of The Baron able to play Chess960 competed at Livingston Chess960 Computer World Championship, the Chess960CWC 2005 and Chess960CWC 2006.
