shove AK if you have 20BB or less out of position. Late, x2.5 raise.as should play AK as an all-in before almost always lose to a medium pair
How to best play AK highly depends on your position, if people have raised already, how you have played other strong hands before etc
But AK is always a risky hand. If you Hit A or K you most likely win, but we all remember many cases we didnt hit anything right?
