Pocket Queens - spewing like a mofo??

[celiboy]

Hero has QQ UTG+1. I have zero hands on villain, but he did sit down with 10 BB's at the table which usually indicates fish city.

.5/1 9 handed..........

UTG BETS, Hero RAISES, folds to cut off, cut off 3 BETS, UTG folds, Hero CAPS

Flop
A/7/3 rainbow

Hero bets, Villain calls

Turn
2

Hero checks, villain bets, Hero calls

River
9

Hero checks, villain bets, Hero calls

The flop call confused me. If he had AA,AK you would expect a flop raise. I put him on KK here and I think I need to fold after villain's turn bet.
