Preflop I 3bet more, pot size would be up to $8.50 I think, and given you're in the BB I'd add 1-2bb so at least $9 here.

I like your line if you had AA (though I bet turn harder, $12 at least) but with JJ you give him too much of a chance to snag an overcard on the turn. If a K comes on turn you're in a shitty spot. If he was aggro on the turn I may CRAI but the board is a bit too connected for that here.

I bet flop for $12 and go from there, probably getting it in if no overs come.

As played I'd c/c if he has shown a tendency to bet rivers when checked to, otherwise I bet smallish (prob $20 actually) for value cos he'll struggle to lay down some Tx hands given your line.

I don't like a block bet, cos it's a horrible spot if we get raised which we may do quite a lot.
