Learn The Game Of Golf

A friend of mine has been asking me for some golf tips. We often play together and I always beat him. I know that he does not have what I would class as a proper golf swing but he is very touchy about it and thinks that his different swing sets him apart from other and makes him more likely to win. I do not want to hit a raw nerve and suggest that he work on his swing as I would not like to fall out over it. On the other hand, if he really does want some advise on how to improve his game, then starting with his swing would be the best thing to do. I wonder if I just tell him what aspects of my game that I a working on and then leave him to come to his own conclusions as to whether that would be any use for him.
