Bodog 20/40 LHE (5-handed)

Cobalt is BB. Cobalt doesn't have an ace or pair. Button has been relentlessly stealing the blinds. At least twice, he's gotten to showdown after open-raising the button with J7o...and there's reason to believe he might be doing it with worse hands. He's generally loose-aggressive. He usually auto-bets when he's checked to, and he likes to peel cards with little chance of improvement. Cobalt hasn't really played back at him much yet...mostly pre-flop folding and check/folding the flop...though villain did show a willingness to fold later in the hand when Cobalt 3-bet pre-flop. Essentially, Cobalt has decent respect for being TAG.

Pre-flop:
2 folds, Button raises, 1 fold, Cobalt calls

Flop (4 SB): 5 A 3 (2 players)
Cobalt checks, Button bets, Cobalt raises, Button calls

Turn (4 BB): J (2 players)
Cobalt bets, Button calls

River (6 BB): T (2 players)
Cobalt bets

Have you seen him call down much? If he's a LAG, a call down is a little suspicious. But, you bluffed, so what if he happens to have a hand?

Personally, I like to use either the stop and go, or call/check raise turn bluffs against these guys. I use the flop c/r against the timid guys.

Not all the way. I have seen him peel to the river and fold a number of times. And, in that case, he'd happen to have a hand. Can't let the opponent possibly having a hand stop you from bluffing.

I think "check/call, check/raise" is a viable line, but it probably would've cost an extra SB in this case (I don't think he'd ever bet/folded a street).
