Hero...

CO is 37/8/1.4 over 100 hands, WTSD 33 and has $500 left on the turn. I busted his set with 63o some orbits before and he seemed to be going after me a bit.
BB obv doesn't really matter in this hand. I think at least calling his 3bet PF is standard or should I raise there? I don't think CO is calling a push with anything worse than AK. He's fairly loose/passive, but I haven't seen him spew around.
Now the flop is really dry and i just c/c (good/bad?), because I think I will only get a lot of action if he has me beat.
What do I do on the turn now?

200$

Shove any river.

shove pre after bb goes allin

I would play the hand preflop, like u usally play ur big pairs.

What range du you have for villian on turn?

You're under representing you hand, both pre-flop and flop. Bet on turn will look very strong, and villain will mostly likely fold or stay with better hand. If you check, he's likely to take a shot on turn again with a smallish bet, at which point you can shove. He might interpret that as a semi-bluff and call

4-bet preflop. As played I would donk the turn.

+1

as played i would donk the turn and probably fire again on the river...i would hate to be raised in this spot OOP and the 2 is a pretty safe card for every1 so checking okay too
