There are many different cases fixing one problem may not be hard but there are many different problems see the following: Illegal pawn structure: [D]8/8/8/8/k7/P7/PP6/K7 w - - 0 1 illegal position in normal chess because the bishop cannot go to d1. [D]8/8/8/8/3k4/2p1p3/2P1P3/3BK3 w - - 0 1 pawn structure that is impossible with 16 black pieces [D]rnbqkbnr/pppppppp/8/8/8/1P6/1PPPPPPP/RNBQKBNR w KQkq - 0 1 pawn structure that is impossible with 15 black pieces [D]rnbqkbnr/ppp1pppp/8/3P4/8/7P/PPPP1P1P/RNBQKBNR w KQkq - 0 1 > >I don't believe it. > >The beauty of true standalone chess engines (exe's) is that you don't need a GUI >to play them or for that matter to implement the rules.

If you claim that it is unfair then you have a point but detecting illegal position is not an advantage of the fritz gui.

No joke, plain >old stoic console mode. Who do think would be champion then Uri? I think that Shredder will be the champion at console mode Shredder does not need the chessbase GUI and has GUI of the same programmer of the engine(SMK). > >The engines that I stated earlier perform when in illegal positions.

Fixing these bugs is not something important for programmers who prepare for WCCC. Uri
