I don't mind how you played it post flop. I agree that a lot of guys check that turn after you call the CR. Or at least, I think a lot of hands you lose to bet the turn again.
However, I don't like pf. I don't like pfr less than x4. I often make x5 or x6 especially when I don't really want a lot of callers like with AK OOP. Actually I usually limp AK in UTG as I find I win more by trapping weaker aces than anything else.
Raising x3 or x3.5BB as a scent of weakness to it like AJ or TT. Your opponent might read that and fire like he did on the turn. I say make it x4 so they don't know if its AA or AK
