600NL JJ this time

6 handed 600NL game.
Me $750 - in CO
BB $550

I have a pretty loose image, I pretty much continuation bet all the time. BB seems to be fishy, playing too many hands and limping and calling too much preflop, doing the nomal fishy stuff.

My hand: :jh: :jc:

UTG limps so I raise it up to $27, my standard pot raise preflop, BB calls, UTG folds.

Flop: ($60 pot)
:3s: :7h: :6c:

BB checks, I make a bet of $45 into a $60 pot like I usually do, BB minraises me to $90. Whats my play? What would you put him on?

This is another 3 bet back. You're a chronic continuation player. Players at 600 NL are going to play back at you on rag flops with two cards. This increases the liklihood your JJ is still ahead.

Yes, that's right, I believed I was ahead here, and since JJ is pretty vulnerable, I should have 3 bet here to protect my hand, but I didn't. I decided to call, wich I think can be ok holding KK or AA here on this flop. Anyways, I called and turn came:

:3s: :7h: :6c: - :5h:

He quickly checks to me, leading me to believe I'm ahead here, maybe against just overcards or against a lower overpair, A6, A7 or some other wierd hand. I bet $120 into the $220 pot. He pushes all in.

What can I put him on now? Do I call this?

Easy fold. I might just check behind on the turn, then value bet the river if he checks, partially to avoid a situation like the one described.

He has a 4. quick check sometimes = gin card. Besides if he really has nothing he will fold to your bet anyway. Easy check behind on turn.

call the flop min raise. check behind on that turn card

I would've 3-bet flop to at least $180, then checked turn
but given your flop play, the 1/2 pot turn bet isn't horrible
