Cassandre,
an Chess Engine Communication Protocol and UCI compliant open source chess engine under the terms of the GNU General Public License (GPL) by Raphael Grundrich, Thomas Adolph and Jean-Francois Romang,
written in C++ and first released in March 2003. Cassandre started as a student project at Louis Pasteur University, Strasbourg [2].
Description
Cassandre is a bitboard engine using rotated bitboards with 256 occupancy states to determine sliding piece attacks, bitscan aka first- and last one by conditional 16-bit lookups, and population count by eight byte lookups credited to Dann Corbit [3]. Cassandre greatly lacks any move ordering except generating captures before quiet moves. The structure of the move generation serialization loops is an instructive counterexample of how one shouldn't write a bitboard engine.
