Effective Stacks:

Hero: $325
Villain: $200

Villain is a very loose player, 3 bets way to loose. Saw a showdown when he 3 bet with A6o. Has bet draws and raised air. Not many show downs of strong holdings.

Hero has 55 in CO. 2 Players limp, I limp, Villain in sb completes and bb checks.

Flop: Kc3s9h

Action checks around

Turn: 5c

Villain leads for $10, all fold I make it 30 to go.

River 10c

Villain leads for $45, Hero???

Calls

Raise/fold. Worse two pair will call. If raised you are likely against a straight/Backdoor flush. $100 would be good to get K9/KT/9T to call

click it back on the river.

Raise. Is he likely to lead here on the turn with a gutshot or flush draw, then peel a card to your raise with just one to go? You got your wish that he lead out again and now you can raise him - again.

My gut reaction was to raise... but I'm not sure how often you're called by worse vs. called by better vs. raised by worse here. This is a very conservative view but I really think we should be calling here. However, since villain is very loose I am more inclined to raise here... Still, think about what you will do if you raise and villain ships. If you'll fold in that scenario, given villain's laggy image, we should just call.

Call vs. LAG I think he's going to have flush alot w this line. I don't suggest raising because villain will shove w flush.

If we click it back and villain shoves we'll have to call just 80 to win 410 pot...don't really feel like raise/folding is much of an option here. If we're raising we're inducing but villain has to know he has no fold equity.

I'd opt to be more nitty here and just call. I'd weigh c=>r/c>>>>>>>>>>r/f

Villain only has ~$125 left, so it's either a call or a shove.

Two draws did get there (flush / gutshot), so I'd probably just call, but I'm weak like that. But Setsy is right, lottsa worse two pair hands will call, so we're missing value out of those hands.

I was gonna say min-raise/fold, but the problem against a crappy player is that he will 3-bet AI very light...

I think we have to flat here...

at least half the pot would be the bet

I just call but I'm an enormous pussy at times. This looks like something that got there and beats us, but I am not folding v. this villain here either.

RAISE/Fold

considering pot/stack size, the pot is going to be at least 160 with a call, if he makes any sort of raise it would certainly be for a very large portion of his remaining stack and to suggest a raise/fold seems really leaky. This seems like a call or shove situation, and i think is very dependent on how you've seen the villain play his 2 pair and backdoor draw hands.

For starters however, i probably raise more on the turn (45ish) to make the decision a lot easier for us on the river because it makes SPR a lot less awkward. I wouldn't think its too surprising if villain even shows up with 33 here (I would think that villain raises KK and probably 99) that he tried to slow play on the flop because i find loose/laggy players try to trap when they hit a good hand.

"not many showdowns of good holdings" was in the OP. Any calls he make with really bad holdings?

If all you've seen him do is bluff a bunch, I just want to call, but if I've seen him even contemplate hero-calling, I jam here. I think he has KT/T9 here some amount, some flushes for sure.

I think I jam here anyways. If we aren't jamming sets, isn't our range too much only QJcc/XXcc in this spot when we jam?

I know ranges don't matter to this villain, but it's worth considering here.

Not that thinking like this is wrong, but people are always playing level 0-1 poker at 1/2 and its usually leveling like this that ends up costing myself the bigger parts of my stacks. My golden rule of playing 1/2 is to assume people are idiots until they prove you otherwise, then just stay out of their way

Well here was my thought process as what to do. I looked at that lead strong and valuey. I know he has shown down weak holdings but that was due to just calling, not him being the aggressor. A raise here felt spewy because it was checked around on the flop. If he had some piece of the flop I see him leading it. He lead the turn, which was a huge blank, which screamed draw or middle pair. A call and then lead on river screamed improvement, a 2 pair is a possibility but i assumed the lead was way to valueish for a 2 pair type hand.

Raise and obv call a shove. Vs a LAG of your description and these stack sizes i dont see how everyone is so scared here. i think we are missing a ton of value from worse by just calling. you got exactly what it looks like you wanted by raising the turn and now you are considering raise/folding???? why are we raising the turn if this is the case?

No no folding, it's either call/raise and Calling>Raise. After flop checks around and vLAG leads out and calls a raise that's a FD/ turning his hand into a bluff. We are raising turn to get value/charging draws. I call here, Results?

Because on the turn we are most likely good (KK probably woulda raised preflop, sounds like this guy would probably also do that with 99); on the river, the two most obvious draws just came in (flush and gutshot), so a lot more hands now beat us (hands that could have very easily played the whole hand this way).

(but I'm not onside with the raise/fold either due to stack sizes)

I called. He had the flush. 84cc.
