If they run at the same speed, and you have a lower branch factor, you should win. If you don't, then I guess your pruning is faulty in the lower plies. The thing gets muddy when people do pruning/extensions, the simple exponential model doesn't really hold water, eg. I suspect the branch factor is not even a constant as a function of depth. -S. >Uri
