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 2. 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.
