a shove on this river is really bad i think for a couple of reasons ... one, you have ~75 behind or something and the pot is like 50, it doesn't make sense. two, you wouldn't have bet only 15 on the turn if you wanted to play for more money, you woulda bet closer to pot, this would be a very big reason i decide to look you up...and three, you really only represent very few hands by a shove, 22, 88, QQ, and maybe AQ hoping to get looked up by KQ or QJ (and also hoping he didn't catch 2 pr w/ QT)? That just doesn't add up in my mind.

As far as the double barrel goes, i suppose it's ok considering he could have called the flop w/ an 8x hand or something like 99/TT/JJ (which if he only 3bets 2% i don't think he 3bets a UTG raiser with). These hands should all likely fold unless he thinks you've been getting out of line.

What cards should you jam on? I don't think I'd jam on any ... would you jam if a diamond fell? I think you'd want to get paid off and probably would make a value bet, since if he calls the turn he has to be pretty strong. So probably wouldn't jam any river card, also since AQ seems to be a decent part of his range here I don't think I'd like to triple barrel this guy, he might even end up looking you up w/ something like KQ regardless. He just seems too strong after calling the turn.
