EV of AKs vs. 88 heads up

[rjc199]

Theoretical question

You are on the button with AK [img]/images/graemlins/spade.gif[/img] It is folded to you and you raise. The sb folds, the BB calls you with 8 [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/diamond.gif[/img] (2 players to flop, 5 sb's)

He will check-call you on every street with his 88. You will bet when checked to on the flop and turn. On the river you will check it through if you are unimproved, but you will bet if you have either a pair of aces or kings or two pair or better.

What is the EV of such a situation for both hands?
