QQ UTG vs Loose Fish

Main villain is a very loose fish who has been running extremely hot vpiping like 80%. He seems relatively passive, although he does bet when he has a hand, but he is mostly check calling, but he has been making a lot of hands. In a previous hand vs him i flopped a set in a multiway pot and check raised his flop bet large and jammed turn for about 2/3 pot more when top card paired and he found a fold to my surprise which i wasnt happy about.

2/3 w 10 button straddle.

Hero opens red QQ UTG to 40
Fish in CO calls, BTN (decent tag player) calls

Flop 9s 6s 3h

I thought about checking here, but I decided to bet due to the fish. In retrospect i like check better.

Hero bets 70 into 110, CO fish calls, BTN folds.

Turn Th for 9s 6s 3h Th
Not a great card for us completing T9 and 87. Fish definitely has all the offsuit combos here too, plus he has 96 and T6, possibly even 63 from what ive seen.

Hero checks, CO fish bets 125 into about 250.

Hero?
