Postflop, just get it all in with a 1/2 psb and then call any raise. If there's any left on the turn, just stick it in unless the board is HORRIBLE and you know you're toast. You're gonna be behind lots when you see a river, but you'll take it down / get called by TPTK/KK/QQ hands a lot, too. Multiway you lose more, but that's more than conpensated by the amount of dead money left in the pot as various villains stick it in too light or fold after contributing 1/3 of their stack.
