RattateChess, (RattateChess Nosferatu)
a Chess Engine Communication Protocol compliant open source chess engine by Maurizio Monge, written in C++, released under the GNU GPL, first announced in November 2002 1. RattateChess played a strong CIPS 2007, becoming fourth with 4/6. RattateChess Nosferatu played the I.G.W.T. 2013, where it lost from Gaviota in the round of sixteen.

Description

Using a 0x88 board representation, RattateChess performs NegaScout alpha-beta with null move pruning and threat extensions, transposition table and IID inside a fractional ply iterative deepening framework with 1/100 ply resolution. Beside quiescence search, further selectivity is realized by history reductions, futility pruning, recapture extensions, and single-reply extension.

Evaluation

The evaluation considers material through piece-square tables for knights and bishops, bishop pair, pawn structure addressing backward, isolated, doubled and passed pawns, development, square control and center control, rook on (semi) open files and seventh rank, and king safety through (half) open neighbored files, and king piece and piece attack tropism.
