Easiest solution ... make a $5 wager(or something similar)! I played last summer with a co-worker and he would beat me everytime by 5-8 strokes. So one day I decided to make a suggestion. Lets play 50 cent skins and 50 cent greenies on par 3's. I truly believed it would take him 4 or 5 holes to screw up but, sure enough, he accepted, stepped up to the first tee box and hit one of the worst shots I'd seen him ever hit and it continued through out the rest of the round! I finally beat him!!! I guess this could backfire on you but it is worth a shot!
