i tanked quite some time there.What do you do on the river? Villain is a big fish like you can already see by his mindonkbets.

fold, the flush got there

Plz look closely at this river, what does it change and what does his action look like compared to earlier streets? Now answer your own question.

everytime i call here im always beat....

His Range is not only flushes. In this Hand he didnt have a flush.

Not saying his range is only flushes, I'm saying that a flush is by far the most likely. And yeah every once in a while you'll see something diff, some of that still beats us though.

Whatever he had here I'm not interested in, its results oriented and not relevant for analysis of this spot. If he was doing something crazy, fine, note it, adjust in the future. Not having that note at the beginning of the hand makes it impossible to adjust, so we just have to go with what is the most likely range here for a random fish.

Let's look at it this way, a player like this might very well play every suited hand and never folds an FD. So there's your number of flushes in his range. You might also have to incorporate the occasional weirdly played set, as well as QT, if he calls down w that he prob will frontshove this river a decent amount. Look at your pot odds and you can figure out how many worse hands he needs to have to make this a profitable call.

Now they usually dont ever turn showdownvalue (or what they perceive as that) into a bluff and if they don't have the flush themselves they are usually scared ****less you might have it. After all, the FD hitting is the most obvious boardchange that even a fish will be aware of. So he prob doesn't jam hands like mid 2p's here out of fear of loosing to a flush. Not saying he will never do that, but average fish here I recon will do this less then 10% of the time. Maybe a bit more w stronger 2p's or w/e. Rest of it we need him to either somehow have gotten to the river w air (don't think there is a lot of that, if any). So I'll leave the combocount up to you.

Yes you are right and i have the same opinion now that i should fold the River, because he is not clever enough to turn his Pair into a bluff on the river. He had QT obviously
Your first reply had a very arrogant undertone which doesnt really help in a strategy discussion in my opinion.

Well yeah sorry about that, guess I should have put that somewhat diff. Point is and was though to try and get your thinking in the right way so you could answer your own question. Not because I don't want to answer it, but because I think that helps learning a lot more than just saying call or fold.
