UTG posted blind and checked, it's most likely that he has a random six or a fd (situation 3, he has both - and you're still ahead). If he flopped it with 67 then you are only 2:1 behind, but there is a good chance he is drawing. I don't think I can get away from this because UTG can have literally any two cards. I'm pushing, and I hope he calls.
