What could MP3 have called 4 bets on the turn and folded the river with? Not really relevant but I am curious can we put him on a hand that makes sense at all betting points?

I think we are missing a bunch on hands UTG could have assuming he is a 42% players. That's a HIGH number and 20% PFR! And he STILL has a PFAF of 1.5!

He can certainly have:
AA
KK
KT
QQ
99
QJ
AQ
AJ
J9
T8suited
33

All you lose to is 33 and QQ. (If this were a 4 raise game my decision may be altered)

I cap the river.
