I referenced scores of +6 or +7 in this. These are likely won, because the main-line was winning a bishop. The score in Nolot 3 for Junior was something like +0.7. If you follow the line out, it must be an attack with even material or below. There's no mate or crushing win of material at the end of that, so it isn't saying much. If someone else has +6 at the end of that, big deal. If you have a chess problem, the point of which is to play a move that wins material, the problem isn't really solved unless the program wins material in the main line. In this kind of problem, the point is to establish an attack that either forces mate or forces the defending side to give up major material in order to avoid the mate. If this isn't done, the problem isn't "solved". bruce
