Crux, (Crux Chess for Windows) a chess engine by László Szalai, written in Delphi. Crux Chess for Windows runs under Windows either in console mode or with an own GUI, the WinBoard version supports the Chess Engine Communication Protocol. The search is plain alpha-beta improved by null move pruning and the killer heuristic. Crux played the ICT 2001 and various Hungarian Chessprogram Open, where it won the MASPV 2002. Crux' opening book is edited by Pandix book author Csaba Szûts.
