I can tell by your question that you are probably not thinking about it the right way.
Don't call AK a drawing hand.
equity vs. a single hand is largely irrelevant because you are not playing against a single hand but a range of
hands.
For example, 22 is a 53-47 favorite over AKo and 50-50 vs. AKs but an underdog to JTs.
This is again largely irrelevant because these numbers assume showdown which is obviously not guaranteed. There are few times when you would open-fold AK or fold it to a single raise whereas there are many times when you would open-fold 22 or fold 22 to a single raise. Also when someone with AK raises and you call with 22, you have a hard time realizing your equity on a QTx board even if AK doesn't improve.
