I just fold it a lot of the time. Like you said it's really obvious what you have and if you flop top pair, you will never get all-in against a lower pair unless they have a set. If you're up against an unknown you can usually assume he's a passive donk who's only re-raising like 2% of his hands so AK has horrible reverse implied odds and basically sucks in this spot.

I don't necessarily agree, if the three-bet is coming from a total psycho with 60BB or less then I'm more than happy to get all-in preflop with him when I have AK.
