Lets just assume that you are likely ahead of the LAG's range, even though he may have you beat. If MP2 (nit) is as nitty as it sounds like you are describing, what could he possibly be calling with that you can beat. He is not very likely to be calling with TcXc or worse merely because of the fact that you are still behind him to act on the river and could have him crushed, not to mention again that he is in fact a nit. The nit could also just have 99 right here and hoping to get a call from your flush, knowing that you will fold all flushes to any raise. I feel like you are beat too often on this paired board when the big bets are coming in and that strong call ahead of you. I feel like a crying call could be warranted had MP2 folded, however, he did not.

I Would always Call river in this spot. How does The nit have us beat? He cant have higher flushes since he is a nit and Wont Call preflop with any qc xc since we have jc 10c.
most nits Would raise this flop with 99 since its drawy and nits Are so ever afraid of Being drawed out on.

However The lag player might have us beat since he could easely be Playing a lot of qc xc. And all full houses.
However The river bet is smallish and i Would Call here given The Price and The fact there is a good chance we have The Best hand

Raise flop or turn, and GII, imo.

Hello
I am a brand new member and this is my first post, so sorry if I have to introduce myself before but I did not find the place to.
I am French so sorry for the bad English.

OTR :
The LAG is a LAG so he could have a K, a Flush (higher would be Q8 and lower, so really crapy hand to open UTG+1), and off course better hand like AK/99/K9, but we are ahead against these combos.
The nitty has never a higher flush than us and I really don't think he has a full. Even you are on the nitty side, would you not raise a full there?
Anyway, AK is not possible, so 99 would be the only hand.
I cannot put nitty on a precise range, if he has a K why calling 2barrels in a 3 ways pot? KQc?
But for me his call does not show force and i don't think he could hope for a raise on Hero Side if he has a full.

Even if I think we are strongly ahead, if opponents are decent they won't call with lower hands.
I fear more the LAG than the nit here but I just call.

I just called. MP2 had AK. Apparently he just called river to keep me in. LAG acted very upset and claimed to have a Q-high flush. MP2 showed AK, and LAG mucked so we didn't see his cards.

It looks like out of all the responses only Marty McFly would fold and he'd be right. I think it's definitely a tight fold but there's so much action and the dynamics is such that we're really not beating much with our 2d nut flush. The weirdest thing about the hand is that the nit didn't pop his boat OTR leading us to discount boat possibilities.

Honestly, I'm still a bit confused :) I think the biggest problem OTR is that the nit calls OTR. He has a flush minimum. The problem is that he doesn't have many lower flushes than us because he doesn't call many suited connectors in MP2. We block T9s and he's unlikely to have 98s and below. On the other hand he can't have QJs or QTs and he won't play stuff like Q8s and below. So actually... he doesn't have a flush. So then we're only putting him on a boat? But then would he just flat river with a boat?

See, this hand is all f-ed up :) MP2 made an extremely deceptive flat call OTR. I'd definitely fold to a raise.
