Beaches, (BeachesChess)
a WinBoard compliant chess engine by Robert Pope, written in C++, first mentioned and hosted by Benny Antonsson in 2002 [2].
The later published source code with version history from 2006 until 2010 [3] refers a bitboard engine - despite processing many of them per node, using 8-bit occupied state rotated bitboard lookups for sliding pieces - the control structure of the legal move generator and evaluation reminds more on a mailbox approach without piece list.
Search is plain alpha-beta with transposition table, null move pruning and fractional ply decrements with an conventional evaluation, taking material and piece-square tables along with some pawn structure and king safety terms into account, as well the population of ored aggregated attacks per side.
