Yes does not get much better than this!

I would say yes, particularly if any of the players still to act are thinking and liable to squeeze us all large if we just call which would make it expensive to continue. I'd probably use most suited Axs including wheel aces.
Five handed so the opener can be wider than standard for 6 handed UTG and it's less than 3x which makes it cheaper for us to 3bet or call. The caller is capped and less than full stacked so nearly never has a strong holding and we have the magic seat on the BTN and would love to get the shorty to ourselves.
Given I have the BTN I'd make it around the 70c mark, out of position more like 90c.

I don't mind either tbf, our hand is under-represented if we just call and if we hit the A, we can stack off a lot of A8-AJ hands. That said, I do prefer to iso in position, it can just look like a button squeeze as well and maybe encourage one of them to go full spewtard pre flop

I'm leaning towards a flat here because you keep all their dominated hands in and you're IP.

I'm squeezing here with pretty much 100% frequency. Juicy spot for it, and we have a hand we have no issues with bloating the pot pre when IP.
