Revert "Check for easy move just once" This reverts commit a24da071f0d6128c633febab7df55f14475217c3 Seems a regression when tested against 2.3.1 With this patch, have after 20000 games at 60+0.05, we have ELO: 13.42 +-4.8 (95%) LOS: 100.0% Total: 20000 W: 3746 L: 2974 D: 13280 Instead with the patch reverted: ELO: 16.62 +-4.8 (95%) LOS: 100.0% Total: 20000 W: 3816 L: 2860 D: 13324 Although we are within error bounds here we take the conservative approach of not introducing changes that are not proved stronger It doesn't mean that the change shall be weaker, simply that we don't want to take any risk. No functional change.
