Reduction instead of cutoff In master, during singular move analysis, when both the transposition value and a reduced search for the other moves seem to indicate a fail high, we heuristically prune the whole subtree and return an fail high score. This patch is a little bit more cautious in this case, and instead of the risky cutoff, we now search the ttMove with a reduced depth (by two plies).
