Raise pre-flop because there is 5BB in the pot already with no-one who's displayed and affection for their hand. If that was 2 limpers, limping 88 from LP is ok.

OMG, bet the flop. How are you going to get someone's stack if the pot is only $1. You want stacks!!! People will not fold a flush draw to a PSB that is 3-4bb. Fire away. From your position they may interpret it as a steal attempt.

Bet like someone has a hand, if everyone folds so be it.
