an [[UCI]] compliant [[Open Source Engines|open source chess engine]] written by [[Maurizio Sambati]] in [[Cpp|C++]], distributed under the terms of the [[Free Software Foundation#GPL|General Public License]]. Smash played the [[CIPS 2004]], [[CCC 2005]], [[CIPS 2005]], [[CIPS 2007]] [[Italian Computer Chess Championship|Italian Computer Chess Championships]]. 

Smash is a [[Bitboards|bitboard]] engine and uses [[Rotated Bitboards|rotated bitboards]] with 256 [[Occupancy of any Line|line occupancy]] states to generate [[Sliding Piece Attacks|sliding piece attacks]]. While earlier [[WinBoard]] versions used [[MTD(f)]], since 1.0 the [[Iterative Deepening|Iterative deepening]] framework calls a [[Principal Variation Search|principal variation search]]. [[Cpp#ExceptionHandling|Structured exception handling]] is used to catch terminate- and timer exceptions thrown elsewhere. [[Selectivity]] is applied with [[Null Move Pruning#AdaptiveNullMovePruning|adaptive null move]], [[Futility Pruning|futility-]] and [[Delta Pruning|delta pruning]], [[Check Extensions|check-]] and [[One Reply Extensions|one reply extensions]]. A [[Captures|capture]] entering the [[Pawn Endgame|pawn endgame]] is [[Capture Extensions|extended]] by two plies. Beside moves from the [[Transposition Table|transposition table]], and [[MVV-LVA]] for captures, [[Move Ordering|move ordering]] is controlled by [[Killer Heuristic|killer-]] and [[History Heuristic|history heuristic]]. [[Evaluation]] determines positional aspects with [[Piece-Square Tables|piece-square tables]], and considers [[Pawn Structure|pawn structure]], [[King Safety|king safety]] and various positional piece terms. ||
