If you are not calling/shoving 10-14 BB preflop when holding AK, you are in the wrong game. Unless your close to the money, or KNOW your opponent has a big pair, you just gotta go to the races. It's a certain raise from any postiton, so your pretty much stuck. You wait for a top 3 big pair at that stack, your going to most likely get blinded out.
All that being said, I would consider a fold, even short stacked, if there was a ton of action ahead of me....maybe. You watch the table, I assume, so you should have some idea as to the range of certin players shoving range. Bigger stacks can easily afford to try to get lucky with a far wider range. Yet, if two-three short stacks go all in ahead of you and It's going to kill you if you don't win, you might consider a fold. Remeber, AA flys into possible losing territory the more players in the hand. Same thing for AK. But it's really hard not to call. The more all ins, the more likely your looking at showing up with only two over cards to someones pair. But heads up? Unless you just know they have AA, you simply must call. And it's not like no one has ever beat AA with AK...you see it all the time. Sure, it also sucks to show up against 33, hit trip K's on the flop and watch your chips go bye-bye when the guy rivers a 3 for a full, but what are you going to do?
Some folks can never give it up tho. I see that all the time. A tight player goes 2x or 3x preflop, gets a call, and fires away on a board with no paint. If you know he's tight and most likely has a big A or AA and you get lucky with your 89 suited for two pair, you can snap him off and double up. I mean, calling or betting all three streets with ace high is so common, it's no wonder these types get snookered all the time, lol. But get ready - you call a 2x rasie from the BB and call the guy down when you hit bottom pair, knowing what he most likely has, he will call you lots of names. So if you do this remeber the old adage "Never wise up a sucker"
