Crafty is a chess program written by UAB professor Dr. Robert Hyatt. It is directly derived from Cray Blitz, winner of the 1983 and 1986 World Computer Chess Championships. On the February 2006 SSDF ratings list, Crafty was 36th with an ELO rating of 2657 ^*.

Crafty board implementation is internally based on bitboards, 64-bit data structures. The source code of Crafty, written entirely in ANSI C, is available for free (see open-source software). Crafty uses negascout search, killer move heuristics, static exchange evaluation, quiescence search, and pruning, hash tables (transposition/refutation) as well as evaluation caches, selective extensions, recursive null-move search, and many other features (cf manual).

Crafty uses the XBoard protocol, and can also be run with the popular free chess interfaces WinBoard or Arena.
