I feel like making a sick river call here.

Reads: villain is on the loose/passive side preflop, at 42/11. I haven't seen him get too out of line postflop.

Hero is LAG, taking down most of his pots without a showdown.

The river bet smells really fishy.

I don't think he has a flush, as most players make a big river bet after their turn check/raise failed to go through. It's not impossible for him to hold a flush, I just think it's unlikely.

He could have trips aces certainly.

I don't think he has a jack here hardly ever.

He could also have a wide variety of busted straight draws, given his tendency to call loosely pre-flop. Most players who call loosely pre-flop will call again if they flop some sort of straight draw.

I can beat the following hands: KQ, KT, QT, Q8, T8, T7, 87. That's basically all I can beat, but I thought enough of his range constituted these busted draws for me to call.

Final Pot: $38.50
