HUNL 1k on party - Riverspot with trips on dry board facing overbet

BB: $1148.40 (Hero)
SB: $1571.25
Preflop ($15.00) (2 Players)
Hero was dealt J 8
SB raises to $15, Hero calls $10
Flop ($40.00) 2 8 3 (2 Players)
Hero checks, SB bets $29.25, Hero calls $29.25
Turn ($98.50) 8 (2 Players)
Hero checks, SB bets $80, Hero calls $80
River ($258.50) 5 (2 Players)
Hero checks, SB bets $420
About 100 hands into the match. Villian is opening 100% of BTNs and CBing 50%. He is playing fairly straight forward in SRP, which is why I hate this river so much. The board is so dry, that I don't think he is bluffing very often here. However, I am at the top of my range so how can I fold? Maybe it is ok to fold near the top of your range if you feel that villian is not putting pressure on you often enough? Inputs much appreciated!

edit: Villian is a reg. I joined his tables at party.

Villain is a reg? He has to know that he is not repping much and you seem to be having something, which will be tough to fold on this board. Did you float a lot so far? Did he overbet before?

He could have an eight himself, but with two on the board and one in your hand there is only a limited number of combos left. Which leaves him with 22, 33, some 8's and the occasional 55, 99+. But would he overbet those? People have a hard time balancing overbets. I call.

Villian is a reg. He had not overbet yet and I was folding to cb 25ish. On the river I expect to see A4, or a boat a huge portion of the time and I need to be right 38% of the time to make a profitable call. I guess there is always a chance he is spassing out, but the dynamics of the match was just pretty straight forward.

I'm not sure if I can ever fold in a spot like this, so I guess it's just wp by him?

The problem is what are we calling in this spot if not J8? Depending on how thin he valuebets usually I might find some folds, but without a specific read or anything I cant fold. wp I guess

This spot is close, I think. Analyzed in a vacuum, it should be a fold but if it is a fold, you should be making a lot against him by folding when he bets and leading out a lot more often or turns/rivers. Let's break it down mathematically:

EV(fold) = 0
EV(call) = profit * p + loss* (1- p) where p = probability we win
= 285 p - 420 ( 1- p ) = 678p - 420

so the p_breakeven is 62%. So the decision should be if p > 62%, then we call.

now, let's breakdown what this p should roughly be in his case:

p =

if range a) with all boats, all 8x, and AA, KK, QQ and JJ: 62% (tight)
if range b) with range in a), but removing QQ and JJ: 54% (super tight)
if range c) with all boats, all 8x, and all pocket pairs above 5, A5 + random air: 76%++ (might be more reasonable)

where do you think his range is? i would think it is a range wider than a), because in the overall game sense, if it wasn't that wide then you'd be making a lot of profit just folding when he bets turns/rivers and maybe even leading out a higher than usual % of the time.

nice post!

The problem is that I really cant find a hand he is bluffing with here and I don't see him overbetting worse (AA etc) in this spot since it clearly won't be called by worse when I'm considering folding trips.

On the turn his range is probably your c) range, so that call is clearly profitable, but once he bombs the river I think it is probably a fold, even though I can't since we are at the top of our range. However, I guess there is some merit to making an exploitative fold since he seems so straight forward and therefore has it a ton here?

Shouldn't it be 285+420*P-420(1-p), since our profit is going to be pot+villain's bet? I mean your answer for p looks correct, I'm just confused why you only took the pot size as our profits instead of pot+opp bet.

Since your opponent has yet to overbet, and the dynamics of your match are pretty straightforward, its hard to classify this river bet as any kind of bluff.

Your hand looks like an 8. Especially because you play alot more hands with an 8 in them, than 2s and 3s. When your opponents sees that your hand could easily be trips, he opts to overbet with absolutely no bluff card help. 99-AA would never do this on the river with no dynamic. This a polarized bet and since it's unlikely he's bluffing, you're looking at 22, 33, 55, 8X, 46 and maybe A4. I think 22, 33 and K8/A8 should be the most common hands here, since the goal of his play is to get max value out of 8X. But since you have a J kicker, that actually makes a difference. If you had K8 or A8, I'd snap this, but with J8, its kinda close because I think it's very possible that he could be doing this with 89.
Matty_G 12 years, 2 months ago
I totally agree is if probably never bluffing. But wouldn't it be really bad to overbet a hand like 89 in this spot since he will be called by better alot more than by worse? I mean I only have 85,86,87 that he beats and 8T+ that beats him. Maybe fold everything but K8/A8 when he is playing so nitty?

adrian, if we stove the range you suggest (22, 33, 55, 8x, 46 and a4), we have about 25% equity so it's really not super close. but if we were to say, weigh each hand in the range by likelihood given the flop, turn action, we would downweight, A4 and 46 -- this would bring us to something like 40% equity. by stoving up your reasoning/suggested ranges i think it's actually quite a clear fold? really great point with assuming that we have less 2s and 3s in our range, so this really narrows down our own range from the villains perspective, which simplifies the analysis quite a bit.
Adrian Milroy 12 years, 2 months ago
Mattias:

Personally I would only overbet this for value with K8+. I agree that 89 would be a bad candidate for this play, but we can't necessarily assume our opponent thinks that way. I think we have to include all 8X, and weight it slightly towards the higher kickers. So I would agree that with no history, drawing the line on your calling range of K8 should be safe.
Adrian Milroy 12 years, 2 months ago
Quadrangemerge:

I think that A4 is extremely unlikely, then 46 and 55 being unlikely, and honestly 22 and 33 being the most likely. If 8X and 22 and 33 making up the entire range to simplify things (I think he'll have A4 as much as a bluff here), then we are in better shape. I dont use poker stove, but a quick rough estimate shows five 8s lower than ours (84, 86, 87, 89, 8T), and 3 higher (Q8, K8, A8) , (4 combos each) and 6 combos of underfulls (22, 33) and three of 85. If the opponent folds any btns, we'll only have to add 83hh and 82ss. We lose to 23 combos but beat 20. Despite this, I think we'll see the top 3 eights, a lot more than the bottom five so I think this is gonna be a fold on further thought. And like you said, when we add in 55 and 46, things start to get ugly for us (16 combos of 46 hurts the calc alot). I agree with you that we should fold this, this is just how I thought it may be close...

I dont think that hero´s hand neccessarily looks light an eight. Arent we playing any pocket pair the same way? That means villain could also be thinking he would have been raised with a monster some % of the time earlier in the hand and could try to get us off w/e value range we´re holding.

quadrangemerge

Those ranges might be off here. The more I think about it the more I doubt that he is playing pocket pairs that dont make boats this way. Doesnt make much sense unless he is turning them into bluffs to get hero off of 8´s, which is as tough as we´re discussing it.

This means we´re looking at 8´s (and I dont even think all 8´s), boats and some A4 and 46 combos + random air.

We still have to be right ~62,69% of the time (calling 420 to win the 670 in the pot). I didnt stove it, but seems closer to a fold now even though I feel kinda sick about it.

if we remove all over pairs from the villains range, and add minimal amounts of air, as you describe, we are super crushed at 18% equity, so this should be a fold if you assert that range. having said that, i think we'd have to be wary of always putting the opponent on such a nutted range like this on river overjams. i can easily see a dynamic of AA trapping non-boat/set pocket pairs in this spot.
Sean Lefort 12 years, 2 months ago
I'm folding this early in a match if I can't suspect villain to be all that likely to be doing this with bare overcards. (There's not a whole lot else in the potential bluffing hands range). I don't suspect he's introducing this bet-size with thinner value hands like 8X, I expect his value range with this bet (early in a match) to be straights+.

That being said, early street dynamics can drastically alter ranges on the river here. For example, if he's CBing a ton and you're not folding much to them on any street, that sets up a dynamic for him to VB rivers much thinner as well as bluff wider with less suspecting hands (ie. he has more potential bluff combos). Also, if he's shown a tendency to opt for over-bets in a lot of different situations, that also means he'll likely be a lot wider for value in spots like this. If either of these things are true, we're swinging back to calling this.

im never folding this in game. i expect my opponent to see my river range as any ax, some kx and a lot of pp...
someone mentioned, that we are unlikely to have 3x and 2x which is a very good point and put a lot more 8x in our perceived range. so it might actually be a fold
Frandsen 12 years ago
Never folding this, we have way to much Ax and smaller pairs in our range to fold here imo. I think its an ok spot to overbet for villian given that our range contains of mostly bluffcatchers and 8x. I think calling most pairs vs a normal river bet is pretty std. for many, so introducing an overbet here only expecting to get called by 8x seems like a solid idea.
