Given how deep you guys started the hand with, TT is in his range, and if TT is in his range no way we can fold river.
Now, if V had 3-bet to $50 and we 4-bet to $150 and then V called then we can absolutely get off our boat on the river because TT shouldn't be in his 4-bet cold calling range when we put in a sizable preflop 3-bet (unless we have some serious history with V and often get involved in leveling wars).
But given the opening raise was $10 and then V min raises that to $20 *(which could be a bet to juice the pot some) and then we 4-bet to $75 and you guys are $800+ deep, V can flat this with TT to set mine. And if V has a boat and AK is in our range (which it should be) then shoving the TT boat isn't terrible by any stretch.
Just sucks he woke up with AA.
Anyways, the only and I mean ONLY way we can ever fold this river is if we 100% remove TT from villain's range. And I don't see how we can do that. Unless we have him pegged as a nit who never raises with less than JJ then sure, we can put him exclusively on AA. But if he is a normal reg then TT is in his range and if TT is in his range then we make crying call on river
Oh, also realized we can put QJs in his range which gives him a double gutter on the flop (and we checked turn giving him a free card). Granted, that is probably more on the thin side, but I think that 5% or maybe even 10% of the time he can show up here with QJs double gutty straight.
So if 5% of the time V can have a QJ straight, and another 5% of the time he has T8s or A8s bs, and 25% of the time V has TT, then we have to make a crying call on river. And I think those numbers are not unreasonable...
