Bruja

a WinBoard compatible chess engine by Dan Honeycutt, written in C++ and first released in March 2004. In the program's readme file, Dan Honeycutt states that Bruja would never had come to be without the contributions of others, and credits Adrien Regimbald, Bruce Moreland, Robert Hyatt, Carlos del Cacho, and Ed Schröder with their respective programs and descriptions as source of inspiration. A stripped version of Bruja, called Simon, was published as open source engine. || toc =Description= Bruja has a bitboard infrastructure, and uses rotated bitboards to determine sliding piece attacks. It performs strictly legal move generation.

Bruja applies PVS with transposition table inside an iterative deepening fractional ply framework in conjunction with null move pruning, singular, recapture and passed pawn extensions.

Evaluation
Bruja's evaluation initializes attack tables as described in //Evaluation in REBEL// by Ed Schröder, to do hanging piece and static exchange evaluation, and to apply progressive king safety evaluation. Further, Bruja has some pawn structure knowledge and applies piece-square tables.
