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 [1], 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 [2]. It uses a kind of principal variation search, dubbed Node-Type Search (NTS), explicitly considering node types [3], 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.
