There has always been talk of the great risks of null move pruning. Of course there are risks and we all understand what they are. But I prefer to look at it a different way, and consider NOT doing null move prunning as a very risky strategy and actually is a losing strategy. The problem has been touched on by you, it's a lack of real feedback. If you do it a certain way and it has been working for you, it's hard to embrace a new approach. - Don
