Buzz playing Twister [1]

Buzz,
a Chess Engine Communication Protocol compliant chess engine written by Pradu Kannan in C++. An early version is available as open source engine under the GPL [2], intended to be an example program for new chess programmers.

Buzz is a bitboard engine and applies Pradu Kannan's main stream implementation of Magic Bitboards with individual table sizes for each square, later dubbed Fancy Magic Bitboards, the generator is available as open source from the Buzz site. Buzz got a 2.2 x speedup from 32-bits to 64-bits on Core2 [3]. It uses a kind of principal variation search, dubbed Node-Type Search (NTS), explicitly considering node types [4], and utilizes multiple threads for a parallel search. In collaboration with Andres Valverde and Fonzy Bluemers, Buzz' search was incorporated into the team effort Dirty.

Tournaments

So far, Buzz played the first three ACCA Americas' Computer Chess Championships, the ACCA 2006, ACCA 2007, and ACCA 2008, the first two ACCA World Computer Rapid Chess Championships, WCRCC 2007 and WCRCC 2008, as well the CCT9.
