I'm playing 4/8 DC, but the full kill is on, so it's basically 8/16. I have played a fair bit with Villain at this game. He's a mid-20 white male who taps the tank a little too often by sweating strategy at the table. Overall, he's definitely a thinking player, but I perceive him as being somewhat weak tight. I don't feel like he's aggressive enough preflop, and he's sometimes hesitant to call river bets w/ overpair-type hands in potential re-steal type situations. Once, many moons ago playing regular 8/16 Hold'em, I saw him flat a CO raise with AA. I'm also pretty sure that he respects my game.

The other player ("guy") is a 40-something fat white guy who is kind of loose/passive, but not the worst. He might be break-even or a marginal losing player, overall, but he's got quite the mountain of chips in front of him tonight.

Guy limps, I raise AQx EP, Villain on my immediate left 3-bets, the blinds fold, limper calls, I call. (3 players to the flop).

Flop comes Q25 skittles (~10 SB)
Villain bets, guy calls, Hero raises, both call.

Turn is the 7 of purple horseshoes (~8 BB)
Villain checks, guy checks, Hero bets, Villain raises, guy folds.

Is betting the turn automatic here? Is the answer to this question different if it's HU vs. 3-way?
As played, is folding OK, or should I call down getting ~13:2?

Yes, particularly after the flop action.

IMO, no; but, just for clarification, do you mean that the pot becomes hu pf?

IOW, you open, he 3!, all fold and it's hu. You then c/r the flop, he calls, and then screw plays you on the turn. If you c/r the flop, you're pretty much bound to lead the turn in both scenarios. Or, are you suggesting that you c/c to the river if hu pf?

It's a tough spot, but I'd call down. You've got two outs against AA, five against KK and drawing dead against the unlikely QQ. Plus, he might be getting frisky with something JJ or TT since it's a kill pot. (I admit that's a stretch with the third player still in at the turn.)

If the villain is on your immediate left, and you raised in EP, then how is he acting first on each street?

Edit: And it has to be the same villain since it seems only you, guy, and villain-to-your-immediate-left saw the flop.

Sorry, I fudged the action in the OP.

I was the button, raised an LP limper, and Villain 3-bet the SB.

Also, FWIW, Villain tanked for 20-30 seconds before calling the flop raise.

your pf action doesnt make sense. does he have position on your throughout the hand? if so how is he CRing you on the turn?

See above post. I raise LP limper from the OTB, Villain 3! SB.

Based on your description I think he has QQ (1 combo), KK (6 combos), AA (3 combos), maybe AQ (6 combos). Against KK you have 5 outs; AA you have 2 outs. Based on this range folding turn seems right.

if you have not played a million hours with this guy i'd get to showdown. sometimes people get out of line in kill pots and this guy doesn't seem like some crusty old nit so i'd CD and hope he has QQ or something else silly. i'd also cap pre, you have a strong hand in position in a resteal spot with a limper contributing lots of dead money.

This sounds like it could be a monster or it could be a legitimate question.

Does he play more passively or aggressively in kill pots?

I kinda want to fold here but I can see calling down because it's a steal situation. Does he know it's a steal situation (and 3-bet more)?

As a general rule, if I don't know enough about villain to fold, I call.

I like this rule.

I think the correct play is to fold, but I would be seeing a showdown.

Either way I'm calling down.

Who the hell tanks in lhe lol? for 30 sec???

Btw I'm guessing he had qq just by his actions lol but I still think that the call down is correct. Amazing how readable ppl are live eh?
