In case of a hash cutoff I try to reconstruct the PV immediately from hash and store it. At shallow depths nearly 100% of my PV's are correct till the end. If the PV was not complete I skipped the learning for that step. I assumed the PV to be correct, if the evaluated score of the last PV position matched the PV score. I stored the PV's and the PV score after each search termination, so it's an easy check then. >I think the knightcap experiment returned a complete position every time they >returned an evaluation, but this seems somewhat extreme!
