Eeew. This is an ugly spot. Our villain's ranges are mega-huge.
JT could call the flop & turn bets with any number of hands. I think the following are likely:
QsKs, JX, 77, 88, a AsXs, or 4X. QT picked up a better draw after the flop.
The main issue with this hand is that there are no draws that one would call a flop bet with, and get completed on the river. So he's either bluffing
a broken draw with something like QT, or he picked up a spade draw in addition to a pair of aces, 4's, or he's holding QsTs.
I really doubt that he's slowplaying a set or 2 pair this way. A7, J7 seems unlikely, as thats a lot of betting to get through with such a mediocre holding.
Its such a weird series of events. You're right, aragon calling makes a crying call tough. He's been sort of check/calling all of his chips off, so it seems like a really bizarre move.
There are just so few hands that would take his line. 4s5s, QsTs, AsXs, A8, and J8 are the hands that take villain's line (sanely) that have you beat. I think this is worth a crying call just because you're getting ~4:1 on your money. If you're ahead 25% of the time, this play will be profitable. You may see bluffs out of JakeTrevor, and weaker aces from the calling station enough to be profitable.
