Defo need to 3bet here to around 18bb. I would be calling with TT-JJ but think AK needs to be a raise to re-iso the fish and collect the dead money in the pot.

Also if either calls and the flop is Axx/Kxxr it's pretty much an easy situation post flop. Calling is a little too passive for me with AK.

I think it's a fairly easy squeeze for value given the action. As for the sizing, I'd go for something like 0.7$.
