I have 400 hands on this guy. No history with him. Observing his stats he seems a good aggressive regular, who plays 20/17 with 6 of 3bet and 47/38/41 of aggr% on the three streets.
What do you think it is his range of cold calling preflop? And what can be his range on the river? Would you take a different line?

the worst hand hes doing this with it Tx. i just fold I never ever seen a reg bluff jam here. your hand looks like sets+ and regs dont get regs to fold sets+.

I think at best we chop, the other times its JT/flushes

i think you played the hand fine, just ul how the board ran out

he probably had a set or 2 pairs(probably completed OTR), but that flush card didn't scary me, since it was a backdoor flush being completed
he may have a bigger straight, but you have blockers against T...

as played is ok to fold
you beat a bluff and his 2 pairs, but i think in such a dangerous board he wouldn't shove for value his 2 pair

when i played the hand i folded, so i don't know what he had, but i was playing on a lot of tables so the flush card scared me. also i don't think there are a lot of players that have the balls (and the skill) to bluff in this spot. however when i was reviewing the hand i realized that there are only 2 hands of JTs that beat me and three flushes with QJs,AJs and AQs but i'm not sure the last two are coherent with his line. Observing the board he can't have a flush with other hands like suited connectors. Also i was thinking that he could have 77 and he didn't see the straight so he pushed for value. However i would call if i played the hand again. Do you think it is bad?
