Maybe when he does, he goes huge, because he's scared he'll get called, and have to actually play some poker post-flop.
If you fold AK, because you think V only has AA/KK here, and never anything else, okay, you have a reason for your decision. I disagree with your reasoning, but that's okay.
If you call, getting >4:1, it can't be terrible, but it's probably not great. Even if we plan to continue on any A-high or K-high flop, if V really is an old nit, he's probably not going to pay us off with his worse 1P holdings, and we need to wonder / worry about what these other wing-nuts have, when we're five ways to the flop.
In my first comment, I said we could raise, and fold to a jam, without thinking about the stack depths here. I wouldn't raise/fold. I'd just 4B jam.
4B-jamming, as the original raiser in EP, blocking AA/KK, with the ridiculous amount of dead money in the pot, is going to be so massively EV, it's pretty much a no-brainer. Even if he calls and we're flipping, we're getting better than even-money odds when the other V's fold, abandoning the $180 they put into the pot.
