Fencer

Home * Engines * Fencer



Fencer, a private chess engine by Shaun Press , and successor of Vanilla Chess. Fencer uses bitboards to generate moves and evaluate mobility and has a pretty fast evaluation but a slower move generator. The king safety function encourages it to launch attacks which work well against humans but not that much against other programs. Shaun mentioned valuing pieces as {1,4,4,6,12} instead of {1,3,3,5,9}, without any noticeable problems, and it appears Hydra had also headed in that direction, valuing minor pieces closer to 4 pawns than 3. Fencer played the NC3 2004, NC3 2005 and NC3 2006 Australasian National Computer Chess Championships, where it run on a P4 under Linux.
