a private chess engine  by David Blackman, under development since 1989. It has a few extensions, heavy null move pruning, hash tables, a moderately complex evaluation function, and no opening book.
Desperado has played in most of the NC3 tournaments, and all the ANU Carbon-Silicon Tournaments before that. Highlights include a win against IM Guy West the year he became Australian Champion, and two third places in NC3.
