Home * Engines * Treebeard



Treebeard, a multi-platform, commercial chess program developed by Jeff Rollason and Didzis Cirulis. Treebeard, an AI Factory product, applies a complex swapping off material analyzer (SOMA) of the whole board, also considering pins and ties to defend against captures, forks and even mate threats, similar as described in Rollason's SUPER-SOMA approach for Shogi, which guides a probability-based tree search. Treebeard comes with an optional 3D Board as version of Chess for the PC, and is currently the chess engine used by Microsoft for their MSN Chess. Further, Treebeard is incorporated in AI Factory's Chess Free for Android.
