From 67f611f3eb68a9714d41d62777913bb2a4075314 Mon Sep 17 00:00:00 2001 From: Marco Costalba Date: Sat, 1 May 2010 10:34:28 +0100 Subject: [PATCH 1/1] Allow a static evaluation to overwrite an exsisting entry The idea here is that if we cut-off after a stand pat the already exsisting TT entry was not usable with current beta, so overwrite anyway.
