I push too, not that it's a great play.

If you were playing with thinking opponents wouldn't a raise to $8 be bad? You are left with $6 behind and a pot of $18. As villain I would assume the last $6 was going in on the river and I would then have odds to draw. Is this a valid concern or just SnG/MTT thinking? Do you fold if a club, Q, K, 7 comes?

If opponent called the flop with QT you'll win your money back in short order. I don't worry about that at all.
