I'm with iopq on this. I'd often float on hand 2 and I don't think floating is the worst option, since there are a lot more cards that would cause the villain to shut down and we rep a lot of hands by floating. We could be holding a FD, SD, a 9, or what we're actually holding, a small/medium pp. So that really leaves 12 cards that hurt us (3A, 3K, 3Q, 3J). And unless he has an Ace in his hand, or the diamond ace comes on the turn, he won't be betting an ace since it hits the nut flush draw part of our range, and we can rep that too. More often than not, he'd be checking the turn and you can take it down with a bet.

I'm not saying that raising the flop is a bad play, just saying that floating shouldn't be discounted here too. Sometimes I float with air on boards that I think miss the villain's range to try to take the pot down on the turn and play our position.
