MessChess

an experimental chess engine written by Mridul Muralidharan to test ideas on chess game tree search, in particular the effect of heavy move ordering, heavy quiescence search, and various extensions. For instance many programs extend most of the useless checks, where MessChess tries to minimize most of these and the logic for this built into the move ordering code. So far, MessChess applies PVS with aspiration, double null move with R = 3, an extensive quiescence with "good" captures, "good" checks, as well as other tactical moves, and heavily utilizes attack tables for evaluation and move ordering, storing and retrieving results inside the primary and separate qsearch transposition tables, and a pawn structure- and evaluation cache. Messchess played the CCT5 and CCT6 online tournaments, and the WCRCC 2008 ACCA World Computer Rapid Chess Championship. || toc =Selected Games= WCRCC 2008, round 10, Arasan - MessChess code [Event "WCRCC 2008"] [Site "Internet Chess Club"] [Date "2008.06.22"] [Round "10"] [White "Arasan"] [Black "MessChess"] [Result "0-1"]
