Hero is perceived as young kid with aggressive image imo. Villain in the hand is former high stakes pro who actually might be considered a fish now.

2 questions.

1. What do you guys think of my turn line here? I want some strong check back hands in my range + board is so dry that there aren't many bad rivers for my hand.

2. What hands should we be bluff shoving here? Imo AQ+AJ are best bluffs because we block AK, KQ, KJ. Any comments are appreciated.

if you're aggro vs. a fish then checking turn has to be a disaster. use your image and get paid when you actually have good hands - i'd argue hands like KQ/KJ are better check backs to keep range balanced (both b/c you're blocking lots of the draw-type hands V can have in that case and because KJ is noticeably weaker than AK in this specific case - thus AK makes a better value bet whereas KJ makes a better check back.)

river shove mandatory given your line so far.

bluff range is a bit tougher given V knows he's repping Kx+ and trying to bluff a fish off trips is usually a losing proposition. not sure if AQ/AJ are good or bad bluffs given they block some value (KQ, KJ; blocking AK shouldn't be too important given "V1, former high stakes reg" should never be flatting both times pre) and some bluffs (AJ, QJ, J9, whatever other weird gutters V had.)

I do like bluffing the Q/J combos that have the Qs/Js/Qh/Jh in them over the club and diamond kings are on the board. highly unlikely V has weird offsuit Kx combos other than maybe KQ here, so blocking one of the four remaining KJs/KQs combos is nice.
