%description
Sjeng is a xboard compatible chess engine. Sjeng currently plays
standard chess, crazyhouse, bughouse, suicide (aka giveaway or 
anti-chess) and losers. It can also play variants which have the 
same rules as normal chess, but a different starting position. 

Technically, Sjeng is a highly advanced alpha-beta searcher, 
using modern techniques like history and killer moves, 
transposition tables, SEE move ordering and pruning, and 
search enhancements like selective extensions, Aspiration 
Principal Variation Search, Adaptive nullmove pruning, 
Extended Futility Pruning and Limited Razoring. Sjeng can 
use an opening book and learns from the games it plays. 

On 14th of October 2000, Sjeng won it's first title
by becoming the World Computer Crazyhouse Chess Champion.

On December 31th 2000, Sjeng became the first computer
program to reach the #1 spot on the crazyhouse rating list
on the Free Internet Chess Server. It had been #1 on the
Internet Chess Club before.

Early 2001 Sjeng became the #1 losers/giveaway player
on the Internet Chess Club.
