Description

Jazz uses bitboards, first rotated bitboards, later Kindergarten bitboards to determine sliding piece attacks 2. It performs fail-soft alpha-beta principal variation search with quiescence, null move pruning and check extensions. Move ordering considers hash move, mate killers, and along with a SEE, 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 3. The implementation of a multithreaded parallel search along the Young Brothers Wait Concept with lock-less hashing was elaborated by Evert Glebbeek in a April 2013 CCC posting 4. Jazz' evaluation takes material, piece-square tables, pawn structure, mobility, and king safety into account.
