Villain is 32/15/6 through 83 hands. Cbet was 0, 0/2. Was limping a lot usually, 24% of time, 12/51. Called a raise 25%, folded to raise 75%.

I also had a note that he was unable to fold JJ to 3 bets after an A high flop.

Hero posts SB $0.01, BB posts BB $0.02

Pre Flop: (pot: $0.03) Hero has J J

fold, fold, CO raises to $0.12, fold, Hero calls $0.11, BB calls $0.10

Flop: ($0.36, 3 players) 3 J K
Hero bets $0.30, fold, CO raises to $0.60, Hero ???

Usually I would 3bet in this situation, however, because I am OOP in the SB and it's quite a big raise, I decide to flat and re-eval on the flop. Are we happy to 3bet shove here or call and re-evaluate OTT? I feel he prob folds AK to a 3bet shove, unless he has the NFD ( AsKs ) and probably folds a FD as well to a 3bet shove.

Optimal line?
