It's a call. Only hands I see getting played this way (that beat you) are AK or AQ. This guy could have all sorts of shlt here. 4:1 is too good. If this guy's post-flop skills were terrible he'd prob c/r on the turn with an ace like every other donk that tries to scare you away when they have the best hand.

BTW I don't fault anyone who stacks off AJ to AQ/AK when AAxxx comes. It's like stacking KK to AA. In that case, luck kicked u in the nuts. Call.

I also second anyone who says this guy is raising AK outta BB.
