I don't mind about rating points in computer chess. >Kind regards >Bernhard The programs are generalists, and that is the problem. There are some specific cases they do not handle well. KBN vs K in particular requires an extra heuristic in order to perform well. In a normal endgame position you will not try to force the opposing king to the corner that is the same color as the bishop, but this bit of information is extremely important in KBN vs K. So unless you program some extra help in, a program will play that ending sub-optimally. There are always going to be positions that the program doesn't understand as well as a person, since it is different from a person. You are right to demand that specific rare yet interesting cases be covered, though. This probably applies just as well in the middlegame. Computers play their type of game very well, and this is sufficient to do well in most middlegames, but there is obviously a lot of room for improvement. bruce
