I personally still make that play, at these micro limit levels, he might bet all in on the draw too.

You don't know.

You are playing to the Q's to either hit a set, or be an overpair.

You hit the set, you made your hand. You have to play it.

And once again if he does flip over the str8, you have the out's (7 after the flop, 10 after the turn)
