The c-bet flop, check turn, raise river line is suspicious, but there's just so few players at NL25 who bluff raise rivers, so without specific data it's hard to find the call.

As the anti-bluffcatching, pro-thinking mascot your identification of an underbluffed line and using that as the prime data point before lazily rushing to employ blocker heuristics is good but I think you should lean towards paying off here.

Firstly you beat some hands he may raise for value, sure it's a stretch of the imagination but if we always killed the dream we'd be dead inside. If he's capable to raising worse for value that changes everything.

Secondly, he probably should be barrelling his gutshots and strong value given the texture, and you block his most likely value hand given his line which is 55.

However, if he wanted to bluff, he could have just barrelled turn and not waited till you bombed river so I think your fold was likely good.

He most likely has two pairs.

You are getting beaten by A2, 67, 88 and TT. Unlikely he has 88 and TT, with possible straight and flush draws he is unlikely to check turn and give free card. 67 and A2 may be are there.

I think you should call.

And beating what?

Never folding here..
He has two pairs in his range..
You beat:
84, 54 and flush draws or gut shots that missed here.. like 64 and etc..

this is trying to find a way not to fold when you should, this range makes no sense to me

a bluff for starters, our hand completely blocks 55 which should be a huge part of villain's value range

What bluffs play this way?

86s/87s play this way as a bluff. Or pretty much any A7o/A6o Hand yes he has all those combos in his CO range. Look at this guys stats, 38/26 over 1k hands. He has much more air here than an average range.

Also if we are folding 55 here then what does our river calling range look like? We just call straights lol. That sounds like a good strategy.

bluffs?

You're folding an extremely strong hand given your range because you're arbitrarily deciding that your opponent just isn't bluffing for some reason.
Your opponent can have any random air hand that gave up on the turn and is putting you on missed spades or something. They may have been slowplaying a worse set.

@Valis, His reasoning for thinking villian isn't bluffing is certainly not arbitrary. I'm sure he as well as myself has called hundreds of river raises with strong hands such as here and been shown stronger 95%+ of the time.

Intellectually dishonest comment

If you're not going to make the basic effort to use common sense, don't bother replying

Don't ask stupid questions?

I think that question is legit, you can find bluffs in his range, but most natural bluffs 85 (0 combos), 56 (1 combo)..., sure, you can give him hands like A6 or A7 as bluffs, but how likely is it that someone is not going to bet turn with gutter but then raise river with it.

Come on, CO can bluff with any combo he stabs the flop with.

CO basiclaly gets to the river with 60-70% of his opening range - depending on what he cbets. So, a **** ton of air.

We block 55, 67 bets the turn, we are only worried about A2 imo.
Still a snap call for me...

i somehow dislike the size of river probe against that specific Villain typ.
how often does he fold vs river prober? maybe block river to induce or x/r

We are supposed to do a lot of blocking otr

Not necessarily with this combo but with our overall range...
