Villian and i are both multitabling and are at like 6-7 tables together. I've been playing pretty LAGgy and as a result villian and i have been 3 betting eachother a lot. He seems a bit loose for a multitabling reg but nothing out of the ordinary. We have not yet 4 bet eachother up untill this hand.

So after i 4 bet and get called im basically done with the hand if villian shows any aggression. When he checks the flop and turn i figure he must have AK since we are both fairly deepstacked and JJ-QQ should have bet the turn cuz if he wants to get stacks in he has to do it in 2 streets. Maybe KK checks twice but he has to have bet AA on the flop or turn right ??
So do i bluff river and if yes, how much ??
