Requiem

a WinBoard protocol 2 compliant chess engine written by Severi Salminen in C with some x86 assembly routines, first released in December 2001. As bitboard engine, it uses rotated bitboards to calculate sliding piece attacks, and otherwise applies PVS alpha-beta with null move pruning, mate threat extensions, futility pruning, and SEE inside an iterative deepening framework without aspiration windows. Requem has a simple evaluation function supported by a pawn hash table, and has some sense of pawn islands. It is not aware of repetitions, and lacks a main transposition table. || toc =Forum Posts=
