$5 NLHE 6-max: Fold or Call River Check Raise

Tend to struggle with these. How many Bluffs vs Value does villain have
Also prob should have bet more on flop as quite a few draws.
Was going to check river, but when the 3 paired I was beating alot of his 2pair hands on the turn

Given small blinds stats, its possible he has a 3
Its very possible he has a worse2 pair.
It is most possible his manic aggression with few hand doesn't respect a cutoff 3bet.
My initial assumption is call.


I will run some numbers now and re evaluate.
Here are hands I think a loose preflop and tight post flop player might call a 3bet AND continue on this flop with.
99+,33,AJs,AcTc,AhTh,AsTs,Ac9c,Ad9d,As9s,Ac3c,As3s,QJs,JTs,T9s,98ss

At this point you have 58.4% 41.6% equity on the flop.
Check Check Turn brings the equities to 50.5% 40.5%
The river gives you the best equity edge of 58% 42%

In other words against this range and apparent aggression you have odds to call.

Your biggest dilemma here is the check raise all in river.
Are you playing with 100 buy ins, or do you have 1/4 your roll at the table?
If you are well bankrolled I think this is an easy call. It will give you valuable information on what villain is willing to flat in the blinds, and insight into his river play.

So small info about your villain, so i'd generaly played tight vs unknowns, i was thinking about his range and mb he has some sets, but unlikely actually, more looks like T9 or JQ 78o also or any fd draw, river check raise so it like 50/50 or he trying to kick off from bank with miss fd or just value bet u, vs unknown for me - it's fold.

Check raises on the river are usually insta folds. Against fish check raises are insta folds. To call you need a reason not to do as standard, notes or stats or something like that.

Villain has played 4 out of 6 hands, the likelihood he is fish is quite large. Aggression indicators support this theory.

I like B-B/F-X line more, makes it simpler and more value heavy when he calls turns with draws.

I would probably call here just because you checked back the turn. It would make more sense for the villain to lead river if he had you beat. But then again, you would bet A10 on the river (maybe not as big) and he could make you fold with a bluff or even better hands. I might fold AA here and call KK since you have blockers to the straight. But that is if we are debating folding here and you need some value hands to fold.

agreed, you have the nut str8 blocked, you checked back the turn so if he has a set I think he is leading the river to avoid a check back. but an unknown check raising the river id fold I believe.
