[Sparta45]

I think checking is the correct move, but one thing nobody has pointed out that I think is worth mentioning is that I would be more tempted to bet at this flop, then if we actually picked up a straight or a flush draw. If we picked up our flush draw or straight draw if somebody is trapping with a big hand, we might be able to burn them on the turn by taking the free card now. On the other hand, in this situation, if we take a stab and somebody comes over the top of us, we can easily let go of this hand knowing we were behind anyway. Likewise, if we bet a draw in this situation, we might have to put it down anyway if villian makes a large re-raise over the top of us.

In a heads up pot I might bet the draw, but in a big multi-way like this, I would take the free card if we picked up our draw.
