300/600 60a

Hero 33.8k sitting utg+2 , utg opens to 1,500 off 32k stack, utg1 folds,

Hero? (a few guys behind with less than 10bbs others had 40+ bbs, table had been spewy after a few orbits here. also I had just raised the last 2 hands before this with big hands.)

I flat 1500 with AhAd

BB flats off 42k stack, 3 to the flop. Pot- 5,340

Flop Jc7c9h

bb checks, utg bets 2,400, Hero?

I call. I feel this board looks good against utg but bad against the bb. didn't see a reason to raise here as I could be way ahead and wanna conceal my hand still and see what develops on this dangerous board. plus i'm in position.)

BB calls- pot 12,360

Turn 7h

BB check, UTG bets 5,400, Hero?

I call. I still feel I'm ahead but am weary of the BB. Curious if maybe I should be jamming here? I could be well ahead and I wanna force BB to pay max if he has a good draw.

BB calls pot 28,560

River 3h

BB fires 11,500, utg folds, Hero?

I'll be left with like 10-11k (less than 20bbs). He looks pretty strong here but could he betting worse? J9, AJ, missed clubs something like Kc10c, 9c10c, or is he always bladed here? Thanks.
