Cupcake,
a Chess Engine Communication Protocol compliant open source chess engine by Dan Honeycutt, written in Java, first released in June, 2012.
Cupcake [1]

Description

Cupcake's move generator is almost identical to Bruja's, Dan's earlier C++ program, but its speed is about half [2]. Cupcake utilizes rotated bitboards for sliding piece attacks. The Java-bitscan uses the 64-bit De Bruijn multiplication.

Search

Search is PVS with transposition table inside an iterative deepening framework with aspiration windows in conjunction with null move pruning, LMR, and check extensions.

Evaluation

Cupcake applies a tapered eval for a smooth transition between the game phases and interpolates between the aggregated opening and endgame scores. Beside material balance of point values and piece-square tables, Cupcake considers mobility, king safety, and pawn structure including passed pawns.
