Heads up strategy guide?

[fishhead]

I play home game tourneys and consistently make it to the final two, but I almost invariably end up 2nd. Sure, I've had a fair share of bad beats, but 75% 2nd place finishes indicates a trend. Can one of you guys lay out a general strategy guide for heads up play? When to push relative to the blinds, what cards to push, how to play TPTK (maybe it's bad luck, but I've had 7 consecutive tourneys with TPTK losing to ragged 2 pairs and flopped straights), trapping vs. betting pairs, how much to open raise, etc. Sorry for the generalities, but I'm looking for help along the lines of Aleo's 10+1 Guide.

Fyi, we usually have a total of T800-T900 chips in play with blinds at 20/40 when we are heads up.

Thanks!
