 Sjeng by Gian-Carlo Pascutto

Sjeng was an attempt to create a bughouse & crazyhouse playing program that can attain a level comparable to what the best human players are capable of. Newer versions of Sjeng also play standard, suicide, giveaway and losers chess.

It has successfully beaten players rated over 2500 points, including several titled GM's and IM's. One version of Sjeng even attained the first place in the crazyhouse players list on the Internet Chess Club (ICC), and the first place on the Free Internet Chess Server (FICS). Its crazyhouse rating currently fluctuates around 2300 points.

Sjeng is probably a bit weaker in bughouse than it is in crazyhouse. Most Sjeng's on the FICS have a rating of about 2000 points in bughouse, with a top of over 2200 points.

For standard chess, Sjeng's rating is probably about 2450 ELO. In suicide and losers chess Sjeng beats all but the very best humans, and will beat non-specialized programs easily.
