Heads up with a buddy

[flapgreen]

I'll be playing a buddy of mine tonight heads up nl. I called him out making fun of his play on a private messageboard so he challenged me to a heads up match tonight. He's only played a few times and he isn't that good but he sure does think he's good. He'll be bluffing some for sure. He always says I only play when I'm getting the cards so he'll be bluffing. Any tips on how to play a heads up match differently against someone like that as opposed to a full ring? style of play, hand selection, agressiveness, etc. I've read Cloutier's and McEvoy's books on nl and he, of course, has never touched a poker book. If I somehow happen to lose, the guys won't ever let me live this one down. I know I'm much better than him but I want the biggest edge I can get. How do I maximize my chances?
