Simplify "easy move" detection Detect a move as easy only if it is the only one ;-) or if is much better than remaining ones after we have spent 20% of search time. Tests are ongoing, but it seems this semplification stands. Anyhow it is experimental for now and could be reverted/improved with further work Gary is testing right now. No functional change.
