The key element to this hand is stack size, starting stack in these events is 3000 chips. Thats 150 bb"s deep, AK has a completely different relevent value in this spot compared to say 20 bb"s when its a monster. Also, Rizen has considerable edge over the field, which is a factor, a bad spot for him may be as good as it gets for mere mortals.
Regarding AK in a 100 bb cash scenario, as is often the case, it depends. AK has lots of equity against most 3 bet ranges but the lower the stakes the tighter the 4 bet ranges become and thats when AK loses value ( history may widen ranges but only slightly ). Versus a tight 4 bet range of QQ+, AQs+, AKo, AK has only 43% equity and very little in the way of fold equity.
The thing is though, without AK, your 4 bet / all in preflop range is unbalanced and exploitable. So taking slightly the worst of it on occasion has to be evaluated in conjunction with the action it induces at the top of your range.
