[Middle English, from Old English cræftig, strong, skillful, from cræft, skill.]
craftily craft'i·ly adv.
adjective
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 [1]. In the World Computer Chess Championships 2004 Crafty won the fourth place with the same number of points as the third place finisher, Fritz 8, despite running on stronger hardware than all other programs.
Crafty uses the Chess Engine Communication Protocol and can run under the popular chess interfaces XBoard and Arena.
Crafty is written in ANSI C with assembly language routines available on some CPUs, and is very portable. Crafty is open source software, but the author retains full copyright.
Crafty pioneered the use of rotated bitboard data structures to represent the chess board, and was one of the first chess programs to support multiple processors. It also includes negascout search, the killer move heuristic, static exchange evaluation, quiescence search, alpha-beta pruning, a transposition table, a refutation table, an evaluation cache, selective extensions, recursive null-move search, and many other features (cf manual). Special editions of the program include enhanced features such as an opening book, positional learning, and an endgame tablebase.
Crafty is one of the programs included in the SPEC-CPU benchmark test. It is also included as an additional engine in Fritz.
