I get 77 in the BB. Villain open-raises to $3.50 from UTG. I'm the only caller.
Flop:

Question 1) How likely is it that my hand is still good? I'd be surprised if he flat called my flop bet with JJ or QQ; it's possible that he'd flat call with a draw, although more likely that he'd raise that.
Question 2) What's my play? Since I weighed his range towards AK, I checkraised allin here. Very bad?
