=Description=
Cupcake's [[Move Generation|move generator]] is almost identical to [[Bruja|Bruja's]], Dan's earlier [[Cpp|C++]] program, but its speed is about half <ref>[[http://www.talkchess.com/forum/viewtopic.php?t=44023|Cupcake]] by [[Dan Honeycutt]], [[CCC]], June 11, 2012</ref>. Cupcake utilizes [[Rotated Bitboards|rotated bitboards]] for [[Sliding Piece Attacks|sliding piece attacks]]. The [[Java-Bitscan|Java-bitscan]] uses the 64-bit [[BitScan#DeBruijnMultiplation|De Bruijn multiplication]].

==Search==
[[Search]] is [[Principal Variation Search|PVS]] with [[Transposition Table|transposition table]] inside an [[Iterative Deepening|iterative deepening]] framework with [[Aspiration Windows|aspiration windows]] in conjunction with [[Null Move Pruning|null move pruning]], [[Late Move Reductions|LMR]], and [[Check Extensions|check extensions]].

==Evaluation==
Cupcake applies a [[Tapered Eval|tapered eval]] for a smooth transition between the [[Game Phases|game phases]] and interpolates between the aggregated [[Opening|opening]] and [[Endgame|endgame]] scores. Beside [[Material#Balance|material balance]] of [[Point Value|point values]] and [[Piece-Square Tables|piece-square tables]], Cupcake considers [[Mobility|mobility]], [[King Safety|king safety]], and [[Pawn Structure|pawn structure]] including [[Passed Pawn|passed pawns]].
