$500 effective stacks. I have 44.

Villain (BTN): Old white guy like late 50's early 60's. He's wearing one of those "gambler visor thingys" and he looks kinda fishy; however, he just sat down with 5 $100 chips and he's folded like 6 hands in a row preflop until this hand.

Hero (MP): Youngish whiteguy with no history with villain.

Preflop: UTG limps, UTG+1 limps, I limp in UTG+3, Villain on BTN limps, blinds complete/check.

Flop($30) 345: Tight Asian guy in SB leads $15, fish in the BB calls $15, I raise to $65, Villain on BTN cold 3bets to $165, Tight Asian in SB folds, Fish folds, Hero?

Notes: Villain is giving off pretty obvious strength tells. I thought this was pretty close, but I felt totally lost when at the table

Bonus questions: What do you do with 33, 55, and A2 in this same spot?

looks like a cooler situation is setting up. You don't have top set so you are in awful shape against that. You have about 30% vs a straight. He probably has one of those 2 hands unless he's a fish. He could maybe have 3's or 56 but I doubt it and you block the most likely 2 pair hands.

I probably jam it in vs an unknown gamble type player, but don't hate a fold vs a player who should only have top set or better in this spot based on pre flop action.

Pot is $290, and it's $100 more to you. Your call would represent just over 1/3 of the pot (34.5%). This really depends on how you range him. You have 38% equity against a range of 55,33,A2s,76s,76o, but only 31% if we drop 33 and it goes back up to 35% if we range him on straights only. You have to assume that he's going AI OTT if we call, and we'll have a very marginal spot we miss our boat/quads outs (Our equity will drop to 22-29% and calling his shove will cost us $330 of a total pot of 1050, or 31%).

OTOH, we likely have IOs if we hit our 7-outer OTT, unless V is very mubsy.

It's very close, and I'd likely decide based on tilt factors. How much it would tilt us to lose a stack here vs. whether we think V is willing to re-buy and spew off more money trying to get revenge. In game I'd probably fold, as I know that even when I think I made the right decision, I play bad for a while after making a play that seems spewy and losing.

+1 I know that's exactly how I'd feel for a while.

There's just sooo many more combos of hands that beat us that the paltry 3 combos of 33 that we dominate. Even if it was EV neutral - I wouldn't take the bet... so why take it when it seems EV-

I think there's a chance villain could have 54o combos at least some of the time. It's still pretty hard to construct a realistic range where we have 50%. People who aren't folding are you calling then folding a turn jam unimproved?

FWIW I think it's a fold.

We don't need 50%, DUCY?

If he has 45o in his range, he definitely also has the other sets and 45s. If we believe that, we have 32% equity OTT unimproved and should be calling. We also have 41.5% OTF against that range, so I'd definitely be c/c. I don't think that's really in his range though.

I meant 50%+ as in having merit of jamming for value on the flop.

We still wouldn't need 50%, as there is dead money in the pot, but we'd lose the few hands we're ahead of to a shove, imo.

This would be a lot easier with reads but when a old guy cold 3bs it's prob the stones like every time. I'd call the flop knowing I'm getting his stack when I boat up OTT, and if I don't I just x/fold.

Don't go broke in limped pots without the nuts.

A cold 3bet on this board, in a limped pot, is a straight like 95% of the time.

If there was a flush draw on the board I'd be cool with continuing, but as it is we make a sad panda face and then fold. Hard to see any hand we are ahead of unless he is super bad.

I think flop is a call and a fold on the turn UI. I think there are a couple cards that can give you a free river (6, 7) and our implied odds when we boat up should make us profit here.

I think he shuts down without a straight most likely so in the rare case you're ahead, you get to know about it.
