20/40 live 9 handed.

CO...seems laggy pre but I don't have a great read post. He has been involved in a decent amount of hands but hasn't shown down much. He's been on the loosing end of most hands. The flop check is suspicious, but I don't know what it means.

CO opens and I defend BB with 9sTc.

As9c3d....it's checked through.

As9c3d4d....How do you proceed?

I'm betting the turn and probably check calling the river.

On turn I want to protect my hands equity vs two high card hands and there's plenty of hands to get value from. (Small pp, 98, 97) On river I want to ensure I get to showdown vs a player that is on the laggy side but I don't know their game too well. If you know they won't bluff raise on river then I think it's close to between bet and c/c. Might be worth giving a lag a chance to bluff even if you aren't worried about a raise.

i b/f, and i don't think ur getting raised often since he has a bunch of non ace-pairs and king highs

if you do get raised, i think you have enough ax to station, and if he's willing to put in 2 big bets to bluff you in this spot, he deserves it...

My default read for a live player is that a checkback is always a trapping Ax; the times it isn't, its JJ-KK. I check turn, begrudging calldown UI since I'm not that confident of this read, but don't hate folding somewhere.

I would chk turn with intention of chk calling turn.

If turn checks through, I would also chk river with intention of chk calling river.

Not folding any run out on river.

Reason I would do above is to get an idea of hand range a bad LAG will chk flop with when losing (possibly tiliting).

Also think easier to induce bets this way in lieu of inducing bluff raises absent reads or history which OP has not indicated vs HERO.

I agree with your default range of a live player. Checking the turn is definately the play. The pot is small so I'm not overly concerned about protecting my hand. I'm not very confident I have the best hand. Give him some rope to stab those times he has nothing.

I think check/call the turn and check/fold the river is about right. Once we call the turn he can't expect us to fold, assuming he is bluffing. He probably wouldn't check the flop with a pair worse than ours and then confidently bet the turn and river.

Check/folding the turn may be the hottest play of all. The pot is tiny and his flop check is awful suspicious. I'd need a lttle more intel on this guy plus a good live read to do this.

Good grief don't fold without knowing this is mubsy TT or AA. We don't punish his flop play by folding this hand! We do it by check raising turn with a good mix and catching some bluffs/value cuts and sucking out some with this hand.

Or JJ's QQ's KK's, Ax and monsters.

A good read would be necessary to fold. I suppose the second diamond on the turn creates some draws, but would he check the flop with a back door flush on such a dry board were he can just take it down with a bet quite often?

Great point about having a good mix of hands to CR turn with. I overlook spots like this too much.

I don't think anybody on a poker forum is going to advocate a turn fold. It's a spot were I feel fine doing it if I have the right read.

I still feel check/call turn and check/fold river is the play. I can live with getting bluffed in a tiny pot.....I'm weighting him having a big pair or Ace here significantly more than a pure bluff.

If he was a complete unknown I just call down.

Check-folding is crazy. I'd rather bet-fold than check-fold. Better still would be to get to showdown.

I say check-call the turn. If the villain checks behind us and the river card is a brick, I think we have a solid value bet.
