a [[Winboard]] compliant chess engine by [[Robert Pope]], written in [[Cpp|C++]], first mentioned and hosted by [[Benny Antonsson]] in 2002 <ref>[[http://www.open-aurec.com/wbforum/viewtopic.php?f=18&t=38196|New WinBoard compatible engine - Beaches 0.96 by Robert Pope]] by [[Benny Antonsson]], [[Computer Chess Forums|Winboard Forum]], July 16, 2002</ref>. The later published source code with version history from 2006 til 2010 <ref>[[https://sites.google.com/site/beacheschess/|BeachesChess]], Here is the source code of a slightly later version of Beaches (2.32)</ref> refers a [[Bitboards|bitboard]] engine - despite processing many of them per node, using 8-bit occupied state [[Rotated Bitboards|rotated bitboard]] lookups for sliding pieces - the control structure of the [[Move Generation#Legal|legal move generator]] and [[Evaluation|evaluation]] reminds more on a [[Mailbox|mailbox]] approach without [[Piece-Lists|piece list]]. Search is plain [[Alpha-Beta|alpha-beta]] with [[Transposition Table|transposition table]], [[Null Move Pruning|null move pruning]] and [[Depth#FractionalPlies|fractional ply decrements]] with an conventional evaluation, taking [[Material|material]] and [[Piece-Square Tables|piece-square tables]] along with some [[Pawn Structure|pawn structure]] and [[King Safety|king safety]] terms into account, as well the [[Population Count|population]] of ored aggregated attacks per side. ||
