I collect them and if there is a pattern >it's not so difficult to make improvements. Ed, Can Rebel9 quickly find the mate in 4 move Ne4xg5 using Normal Selection? Can Rebel9 find the mate in any move in other games using Normal Selection much faster and much better than Rebel8? I don't expect Rebel chess program to be perfect, but I always feel better when Rebel chess program gradually gets closer and closer to perfection. :) Thanks, Eran :) Considering about buying Rebel9 in the future.
