Rabbit

a free 32-bit Windows chess program with an own GUI, written by Roberto Waldteufel, released in 1998 via Đorđe Vidanović's site and Gambit-Soft. Written in Powerbasic, it is augmented with some Assembler to speed up the most CPU intensive parts like the evaluation function and move making and unmaking. Apparently, Rabbit is a bitboard engine and applies the dense version of rotated bitboards considering the attack redundancy of the outer squares. It performs a principal variation search with aspiration windows, preprocessing at the root, and searched about 30K to 50K nodes per second on a Pentium 200 MHz MMX. || toc =Rabbit's Paradise= =Screenshot=
