A few qeustions:

1) What range can I realistically put V on pre-flop? (4-betting an UTG+1 player from the button)
2) Should I have 5-bet all-in preflop? Will a worse hand call?
3) Putting me all-in on the flop - how can I narrow down the range here? I was thinking it's at least JJ+, AKhh. Is this reasonable?
4) Do you read anything into the sizing of picking my (almost exactly) stack size as the flop bet?
5) As played, is this a call or fold?

Make it 9bb pre.
I would shove facing this huge reraise. He could have (JJ),QQ,KK,AA,AKs and you do fine vs that range.

AP, this is a fist pump snap call.

His sizing is pretty awful fwiw both pre and post.

You're playing higher than me so maybe take below with a grain of salt.

1. QQ/AK+ at worst for regs. We've got no idea about this guy which makes it tricky. His sizing is big, but he's still worried about UTG calling with a pocket pair and outsetting him, possibly.
2. I think it's close. This guy has put so much in already that I'd say he won't fold, and I'm not folding KK vs a random. But I'd usually flat a regular 4bet in this spot as indeed, raising would possible narrow his range to KK+.
3. I think JJ might be pushing it, but I think it's reasonable yes. He might just be pushing with a random AK (with a heart blocker) though hoping you fold your JJ/QQ/AK (thinking you'd 5b AA/KK).
4. Not really, he just put you all in in my view.
5. I'm calling vs random for sure and probably vs non-rock regs as well. But I'm not fist pumping as this could very well be AA. I think it's kinda trivial as most people would lose their stack in this spot with KK.

His cold 4b here is strong but I'm 5b shoving preflop all day
