Mental edge has nothing to do with LCW losing. LCW's confidence and play didn't drop. Wrong strategy is the reason. LD changes his style of play during the final few point. This causes LCW who is already under tremendous pressure to make mistakes or play the wrong reply. Chen Long will soon learn to do this as well.. It is during these crucial moments that you need a good coach at the side to remind you about the right play.. LCW didn't have that.
