Refine deeper post-lmr searches This patch improves logic conditions for performing deeper searches after passed LMR. Instead of exceeding alpha by some margin now it requires to exceed the current best value - which may be lower than alpha (but never bigger since we update alpha with bestvalue if it exceeds alpha).
