I have other issues with your post but would really like an answer to the main point:

So you want to Shove here? smaller 5bet seems pointless (I'd missed that you said "keep raising" -sorry 'bout that)
Fair enough but at 5:4 pot odds you're really relying on that "spazz" cos you're making a high-variance play that needs non-PP non-AK in his range not to be losing. I'd still like an explanation of why you want to get it in against {QQ+, AKs} when every hand in that range is ahead or equal and the pot odds are not helpful (even 40% hand equity assumed he had AKo as well and you need 44%).

You've now brought up fold equity. The whole point of my contention is that he's already on at least {QQ+ AK} and simply won't fold.
The main reason to fold AKs PRE is when you know for a fact that villain would never have QQ- or AK-. Their range has to be exactly KK or AA in order for you to fold AKs.
Please explain this. Was this relying on fold equity as well?


In the context of calling at 3:2 it makes some sense if you expect most of your equity to to be realisable from the flop: i.e. the flops you don't like the look of contain very little of your [P] equity (backdoor draws being improbable). I'm not sure that's so however as the [T] and [R] Aces will beat at least half his range for you. Outplaying him is going to be tricky too when he's only got one Pot-bet in him.
Since you don't want to call that's not relevant anyway so I'm at a loss.
