I ran an old hand through pio trying to see what I should look like on rivers. I got some strange results and not sure if this has to do with the ranges I set pre or because of the hand being 3 handed.

Either way I can't come up with a range for villain that isn't extremely imbalanced after turn and as a result we're left with only a few nut combos to call psb on river

Pre I have CO at 28% SB call range of ~14% and BB call range of ~22%

I'm going to leave our hand out for now, effective stacks of 100bb.

CO raise 3bb, SB call, BB call
Pot: 9bb
Flop: 6d7dAh
checks around
Turn: 6d 7d Ah Kd
SB bet 6bb (I believe we should be checking high freq.)
BB raise 22bb (?)
CO fold
SB call
Pot: 53bb
River: 6d 7d Ah Kd 9c
SB check
BB bet 48bb

Both of our ranges are capped pre which makes this hand unusual to me. I'm kind of stuck on coming up with a range for BB since there aren't many bluffs and everything seems to work better as a flat.

At this point we're realistically left with something like 15 combos assuming we're betting the turn often with TP+NFD, flushes, and sets. I'm leaving out 2 pair even though I probably take the same line once in a while. It can work out the same where it's weighted 2/3 of sets, 2 pair, TPGK and 1/3 flushes. We can call accordingly

Messing around with pio the calls were AdQx and flushes (seems ok). A few things I found odd, AdQx was overwhelmingly +EV, more so than Q high flush which had an EV of around 2bb compared to 15+ for AQ. AdJx was slightly under and a fold and 77 was in worse shape than 66.




Obviously the BB seems pretty polarized but how much does being 3 handed change the solution? I'm starting to think a 100% check strategy is best here 3 handed oop with the pfr IP. I folded river and thought it was a huge mistake when I found this hand until now where I'm still not sure. Anyways, I'm admittedly still a pio noob and may be doing something wrong. What do you think?

This was a specific situation... but in general how can we account for postflop with 3+ players in the hand? I've heard that our current understanding of gto can be carried over to multiway pots, is there a way to input more players and tighter ranges in solvers? Is this still up for debate?

I recommend using crev to study multi way situations. Obviously you can't use the solver in a three way pot but you can run sims and study the change in EV of different multi way scenarios.

With a little mathematical creativity you can convert a multi way game into a similar two player game and find an equilibrium.

I'm assuming I have to purchase crev to get anything out of it? Messing around with the free versions feels pretty useless unless I'm missing something

Mathematical creativity is not something for everyone.
Good Luck

I just cant figure crev out lol I haven't had it long but cant run any hands unless I input a new range every street and the tree limit is really small.

Thanks for the suggestions

Not true that you can find equilibrium in multiway NLH when the stacks are deep enough, or in many simplified multiway toy games.

Everything has an equilibrium...

A nash equilibrium is guaranteed to exist for all finite 2+ player games but in practice it can be difficult, if not impossible with current tech, to find that equilibrium depending on the complexity of the game(chinese chess, 3+ nlhe, plo, etc).
