Villain is 13/9, 3bet 5%(19) cbet 100% turn bet 100% Agg 11 only 56 hands though. Seems decent but I've not seen him show down anything yet.

PokerStars No-Limit Hold'em, $0.10 BB (8 handed) - PokerStars Converter Tool from FlopTurnRiver.com

CO ($11.12)
Button ($10.15)
SB ($20.92)
BB ($4.04)
UTG ($10)
Hero (UTG+1) ($23.02)
MP1 ($7.37)
MP2 ($10)

Preflop: Hero is UTG+1 with A, K
1 fold, Hero bets $0.40, 4 folds, SB raises to $1.35, 1 fold, Hero calls $0.95

I just call pre because I have no further reads on him besides my HUD and I decide to play it a little safe. See a flop and see how we go.

So first question.........should I be 4betting and if so to what size and who is calling or folding if he shoves or 5bets large?

Being 13/9 I put him on JJ+, AQs+, AKo. 3bet of 5% means he could be 3betting a bit wider but I don't have a large sample so I'm happy to err on the side of caution.

Flop: ($2.80) J, A, 8 (2 players)
SB bets $1.65, Hero??

I expect the cbet but the sizing was a bit strange being not much more than 1/2 pot. I couldn't decide whether to raise or not. His Agg and turn barrelling tendencies had me thinking just call and give him some rope to fire off on the turn. On the other hand I've got a good hand and want to get the money in. We are both fairly deep so to get stacks in by the river(if it's going to happen at all) I figure I need to raise here.

So if you're raising what size would you make it?
