All, I am using a null-move error finder that works like this: if a null move causes a beta cutoff, I set a flag instead of returning the null move score. If the regular search then doesn't cause a cutoff, it's a failure. This happens in several of the wac positions, causing problems. One solution I've heard of is to disallow null moves in the principle variation. Since I generally ignore the pv during the search, I'd have to do a fair amount of coding to test this. Does restricting null moves in the pv guard against null-move failures? Will
