Final Pot: $85.20

Villian is 40% Vpip Guy after 24 hands or even less.
I don't know what I should put this guy on when calling a raise preflop and after I squeeze minraises. Is this push ok for 18$ more with 32$ allready in the pot? I guess this might be breakeven.

In my experience, this cold call/4bet line from a shorty often is a medium pocket pair that puts you on AK (correctly so this time).

Your fold equity is pretty much 0, but you're in a coinflip - well, a slight dog actually, but there's dead money making up for that.

If villain is weird enough to do this with a few worse hands that you have dominated, your EV just gets better.

With all the dead money this is a must shove against a shorty, imo. Calling is not an option, your AK wants to see 5 community cards not only 3.
