How often is villain triple barrel bluffing in this spot?

Pretty much never. Folding flop is probably best as nitty as it seems.

And fold pre

Even if we had AK we should probably be making an exploitative nit fold on the flop. The board is only semi-wet, it is A-high or K-high which hits our range as PFR. Fish will put us on AK - the raise means that they can beat AK. V can easily show up with AK, AQ, AJ, AT, A5, 55, TT. Bottom of V's range may very well be sonething like KQhh, KJhh, QJhh which still have a lot of equity against us.

That, and fold pre.

Fold A8 pre in the cutoff in an unopened pot?

wait, who is tag fish?

Not sure if troll but I'll take it seriously: BTN is the TAGfish who seems like your typical 1/3 sh*t reg: he knows the basics, but he cold calls too much, opens too loosely in early position, defends his blinds too widely and gets too sticky postflop.

I hate every street.

Raising pre is good if you are confident you can steal the blinds and limps, which worked, so it's unfortunate the button called as it throws a wrench into your whole plan for the hand.

You have to know your table. If you are raising over a limper are you close to 100% confident they will be face-up and passive against you if they call your raise? If they are sticky and tricky, folding pre could be best, or limping in if we have a nit behind us on the button who will fold pre a lot, giving us position for the rest of the hand.

Once the button calls, I am hating this spot, being OOP, so I would probably just give up. Flopping an A is much pretty much gin for your hand, we are wither WA or WB, but with a crap kicker we have to look to play a small pot.

Getting raised on the flop with our holding just made a crappy situation a whole lot crappier, so I would fold here.

A8o sux serious ballz in general. Gimme a hand as crappy as 62suited over A8o imo.

Sorry, I pretty much agree with everyone else here.

In particular, as played you have to check flop in an attempt to keep this pot small. Since you bet, you have to plan to fold b/c your plan can't be to call here and then 1 or 2 more streets after this, right?

Pre-flop you're in CO. There are 2 limpers in front and 3 people still to act behind you. There's a good chance this hand is going to be at least 3-way (somehow it wasn't, but you have to plan for that) and you don't want to play A8o multi-way. Super easy fold pre.

In a nutshell, you didn't seem to have a plan here, but feel free to explain that plan if it existed. In particular, what range are you putting this guy on by the river? If you were putting him on A5 (which got counterfeited) or semi-bluffing a flush draw the whole way then I guess you can call the river, but I think most here (including me) think you were probably behind the whole way and should have got out for less money much earlier in the hand.

But geez, given that you got to the river, if you called here it would be the least bad thing you did on the whole hand, maybe even a good call.

I mean, you look like a guy with nothing better than Ax here and if he semi-bluffed this far with a flush draw then why not try one last half-PSB on the river? I'm made a lot dumber bluffs than that...

Folding pre, folding flop, calling turn, calling river.

Horrendous hand, fold pre

Results:

Cant fold flop after we 1/3 psb and he raises that small. We also block no draws.

Turn is fine, 10x severely reduces his value hands. River is fine too. Probably would have let it go if the board didnt pair

But yeah, A8o is definitely too lose even unopened pot, and definitely too loose for isolating. I'd isolate A10o+

I'm not following this. Obviously reduces AT and TT, but only by 4 combos, and I'd expect to see more AK - AJ and those probably aren't afraid of the T pairing. What am I missing?

My logic for calling down was:
1) Our flop Cbet was so small that it may have induced a spazz (since villains assume that small bets = weak).
2) The turn reduces villain's AT/TT combos, which puts us in better relative shape against his range.
3) Every draw busted on the river, so if we were ahead on the turn, then we're ahead on the river.
4) Villain should 3bet AK most of the time and 3bet AQ at least some of the time, so it's only AJ/AQ that I'm worried about.
5) Does AJ really raise flop and go for 3 barrels? I discounted most AJ combos because I doubted they'd triple barrel in this spot, given that villains at this stake don't typically go for extremely thin value, especially when he thinks that I might be trapping with Tx (that's what my flop bet/call looks like).

Fold because the hand is not strong enough to ISO limpers with - limpers can have A9-AJ, maybe even AQ sometimes, as well as 88-99, all of which have us dominated and will not fold to a raise.

A case could be made for open raising A8o from the CO if it were folded to us.
