Commit ID af7412e58a4ce374b5035d9bb1e8c47a108ff352
Author Joost VandeVondele

Explicitly use alpha+1 for beta in NonPV search (#939) Fixes the only exception, in razoring. The code already does assert(PvNode || (alpha == beta - 1)), and it can be verified by studying the program flow that this is indeed the case, also for the modified line. No functional change.
