One idea I had about A-K that I think is worth noting is that this hand may allow you to effectively represent aces or kings. The fact that you have an ace and a king in your hand means it's unlikely that an opponent has pocket aces or pocket kings, so if you reraise with this hand preflop, then raise big on the flop after missing, you may be able to get an intelligent opponent to fold an overpair, and if not, you may hit an ace or king on the turn or river to kill your opponents pair anyways. I'm not advising actually doing this, but it's an interesting theoretical point, nonetheless.
