Jazz,
an open source engine under the GNU General Public Licence by Evert Glebbeek, written in C, first released in February 2011 [2].
Jazz supports both, the Universal Chess Interface and Chess Engine Communication Protocol, and using appropriate compiles, runs on Windows, Linux and Mac OS X boxes.
Description
Jazz uses bitboards, first rotated bitboards, later Kindergarten bitboards to determine sliding piece attacks [3]. It performs fail-soft alpha-beta with null move pruning and check extensions. Move ordering considers hash move, mate killers, winning captures and promotions. Further, beside the killer heuristic and countermove heuristic, a so called Combo Move heuristics is used to possibly refute opponent moves along similar lines [4] . Jazz' evaluation takes material, piece-square tables, pawn structure, mobility, and king safety into account.
