Fix incorrect assert(PvNode == (alpha != beta - 1)) In case of a PvNode could happen that alpha == beta - 1, for instance in case the same previous node was visited with same beta during a non-pv search, the node failed low and stored beta-1 in TT. Then the node is searched again in PV mode, TT value beta-1 is retrieved and updates alpha that now happens to be beta-1. No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
