V is a huge whale. He calls flop raises with TP type hands but plays ABC afterwards (check/call or check/fold) if he doesn’t improve. Bets small/thinly with his medium showdown value hands like 1p. Has a friendly vibe with me.

H $15 77 MP, 2 calls, V $45 BB, H call, BTN call, SB fold.

Flop ($150): Qd 7d 5h
V $65, H $175, fold, V calls

Turn ($500): Th
V x, H $300, V calls

River ($1100): Jh
V shoves $330, H ???

His tiny flop 3b should never be AA-QQ so I put him on AK/AQ/KQ/KJ/JJ/TT type hands.

On the flop, I mostly discounted AQ out of that range because he’d def go larger but all other hands still possible. I’m way ahead of almost all of them so never felt the need to go bigger.

Yeah you should've made it 200 on flop and shove turn.

But no way you can fold river for this price.

I think you might be reading too much into bet sizing — I don’t think we can say with any confidence that a 3x 3bet sizing can’t be QQ+, or that a ~45% flop cbet can’t be TPTK. A larger sizing might be more likely given these hands, but these hands aren’t that much less likely given the smaller sizing.

with 1.2 spr on the turn, if i am betting anything (and here I obviously am) it is all in. As played the river looks like an easy call.
