Tornado

an UCI compliant chess engine written by Engin Üstün since 2004. Tornado is bitboard based, generates sliding piece attacks with magic bitboards, and applies PVS with aspiration, null move pruning with verification search, internal iterative deepening, razoring, history leaf pruning, futility pruning, late move reductions, and check extensions, one reply and singular extensions, as well as passed pawn extensions, either after establishing a new passer after a capture, or pushes to the 7th rank. Tornado has a multi-threaded search with up to 16 cores, and supports Nalimov tablebases in endgames. Able to play Chess960, Tornado participated at the Chess960CWC 2006, and further at various CCT Tournaments, first was the CCT8 in 2006. || toc =Games= CCT14, round 4, Tornado - The Baron code [Event "CCT14"] [Site "Internet Chess Club"] [Date "2012.02.25"] [Round "4"] [White "Tornado"] [Black "The Baron"] [Result "1-0"]
