Zappa is a chess engine, or a program that plays chess. It is similar to Deep Blue – only much better – and is best known for its good parallel speedup and dead sexy author. It has competed in many computer chess tournaments with its best result coming at the World Computer Chess Championship in 2005, where it took first place with the score of 10.5 / 11. Like Fritz or Shredder, it is a standard chess engine, which in technical terms means it is a brute force alpha-beta searcher with a heuristical evaluation.
