52/3/0.92


Hands like these I am really unsure of. Please try to explain your turn play, or if you would play other street differently than explain why. Are his stats the main thing for a call/fold here. What is the cutoff for the stats that would change your decision?
Ok I will stop posting hands for a bit

I call turn and c/f river UI.

Absolutely drawless flop, yet he calls the K-high-board against a preflopraise. I doubt he improved on the turn, I think he waited with a King, 2pair or set for the turn to raise &gt;90% of the time. There is nothing to semibluff here unless he would call the flop with a gutshot (JT). His stats dont look like he is the type that does a lot of stonecold bluffs.
This hand goes in the muck.

Is this because you expect him to check behind a worse hand sometimes? Because getting 6.5:1 isn't enough for a 5 outer.

I would do the same thing in his shoes with a 9, but then again my post flop agg is 3, not .92. I think it's a call vs an aggresive opponent but a fold vs this guy.

Poldi, thank you for your excellent response.

[joker122]

pretty standard fold against even an unknown. his stats make me feel even better about folding though.

That and I expect to get 1-2 bets more on the river if I hit. This is still an incorrect call?

Well you cannot say your implied odds are 2. If an ace comes you should probably bet out. A 9 you should probably checkraise, but sometimes villain will check through. On average your implied odds are probably like 1.5 or something. Since you need 8.4:1 to call with a 5 outer, this is still not enough. Also sometimes he will have a set. Or you will checkraise and he will fold a weak hand or bluff sometimes (rarely).

Villain needs to check through the river with a weaker hand sometimes (a small percentage of the time) to make this call correct.

EDIT: It is definitely reasonable to think that a LP villain will check a worse hand behind on this river if he was trying some sort of free showdown raise. But how often will such an opponent be making a free showdown raise on this board? Pretty rarely imo. If the turn introduced some draws he could be semibluffing, the pot was a little bigger, or the opponent was more aggressive, I would be seeing a showdown here.
