In the digest of course

Fwiw, 3betting a short stack and not knowing what to do when he shoves over you is a massive leak. Dont just raise him 'just because'. Raise with a plan. When villain sees your raise, a 4bet is much more likely due to how short he is so account for this and have a plan for it.

As to raising an unknown in general. AK plays great when hands like AQ, AJ, and KQ and other similar hands exist and its just meh otherwise. Its a cool hand to make stands with in tough games due to its ability to flip with alot of things...but thats pretty high variance and not really worth it at 5nl. So it basically just comes down to if you can put these hands in his calling/shoving range when you 3bet in the first place.

As to what to do when he 4bets, the spoon article is right there , and its a pretty clear call.
