If so, can you give an example of a move where this is abvious? Well, if you check the last gave we lost we gave a bishop for 2 pawns without enough compensation. Try any Shredder commercial version and none would play that move. During my tests I saw pawns gave away without any compensation and so on. That's why I was worring about what to play to avoid these problems. Another example is the game against Falcon in the WCCC 2004. The program overlooked the check and lost a huge amount of time on obvious moves. Sandro > >Kind regards, >Ernst.
