You can create a strong engine without pruning, but you won't get a top engine without it I think. Once you get yours going, try and print out a few random positions from the search, see the kind of crap that gets searched. It will be all too obvious a lot can be pruned, for instance at ply 3 from the initial position, my engine likes to take its king out for a walk! ;D The problem is to find the rules to it "safely". -S. >Russell
