a [[Private Engines|private chess engine]] by [[Shaun Press]] <ref>[[http://computer-chess.org/doku.php?id=computer_chess:wiki:lists:private_engine_list|Private Engine List]] from [[Ron Murawski|Ron Murawski's]] [[http://computer-chess.org/doku.php?id=home|Computer-Chess Wiki]]</ref>, and successor of [[Vanilla Chess]]. It uses [[Bitboards|bitboards]] to [[Move Generation|generate moves]] and evaluate [[Mobility|mobility]] and has a pretty fast [[Evaluation|evaluation]] but a slower move generator. The [[King Safety|king safety]] function encourages it to launch attacks which work well against humans but not that much against other programs. Shaun mentioned [[Point Value|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 <ref>[[http://www.chesschat.org//showpost.php?p=63437&postcount=10|Re: 2005 National Computer Chess Championships]] by [[Shaun Press]], [[http://www.chesschat.org/archive/index.php/|Chess Chat]], July 17, 2005</ref>.
