Frenzee, a Chess Engine Communication Protocol compatible chess engine by Sune Fischer, written in C++ and capable to play Chess960, first released in January 2002 as ChessCraft and soon renamed to avoid confusion with Crafty. Frenzee is a bitboard engine using Rotated Bitboards to determine sliding piece attacks. It applies PVS and null move pruning, has its own book learning technique, and is able to probe Nalimov tablebases. The parallel searching version Deep Frenzee shares the transposition table. Frenzee further supports UCI in analyze mode.

=Tournament Play= Frenzee played five consecutive CCT Tournaments, starting with CCT5 in January 2003, and two strong ACCA World Computer Rapid Chess Championships, the WCRCC 2007 and WCRCC 2008.
