I wonder if you could just jam this flop. It's so draw heavy V will put you on a draw and call with an overpair. I'm not necessarily recommending this line but if your image is maniac you can probably get away with it.
Bet more OTT IMO. AP easy call. If V2 is TAG he has all KQ combos, so that's 9 KQ combos. He also has 98 and missed heart draws some percentage of the time that he's decided to bluff. Probably not a lot but maybe a few combos. The way the hand was played 77 66 54 all look unlikely. KK is possible but weird he wouldn't raise the flop or turn. That's 3 combos. QQ seems like most likely hand that beats you, but it's still weird he would just flat your donk bet on such a dynamic flop with QQ. If he's good I would expect him to raise QQ OTF. But he's probably not good so maybe he has QQ.
KQ makes the most sense IMO but even if he has KQ and KK / QQ equally often and no bluffs (worst case scenario) that's 9 combos you beat and 6 combos you lose to in a spot you only need to be good like a third of the time. Easy call.
