50NL 6max- Calling all-in with AKs PF with full stacks

[Imrahil]

Villain is a regular and is 18.5/13/3 over almost 400 hands. He's tag but not that great of a player. Like once he raised in the BB with QJo after the entire table limped and he only raised to like $3.

This hand happened last round:

I was getting about 1.32 to 1 odds so I have to win about 43% of the time to break even.

So I'm assuming that this is a slightly +EV call right? I think if I factor in the chance that he's possibly pushing with a marginal hand like KQs my EV goes up more.
