TJchess

TJchess is an engine that plays normal chess, crazyhouse, and bughouse. Playing strength for normal chess is still relatively weak for a computer chess engine, but challenging for most humans. I hope to improve strength in future versions.

TJchess started out as a WinBoard engine, but now there is also a separate UCI version for people who use a UCI interface.  It wasn’t much extra work to add UCI, since TJshogi uses USI.

Features:

• plays standard chess
