this is true guys, but my plan early in comps is to disguise AK somewhat, therefore if the A comes on the flop you can't be put on AK and furthermore you can get away from AK easily if you miss and face action, so you don't have to re-raise and blow chips on a drawing hand
granted though, it can lead to trouble like here
Aganist an early position raiser you should re-raise, against a late position raisor you could try and trap if the have Ax and an Ace comes on the flop. If he has AA or KK then that's life, but you need to know that you are ahead on an A or K high flop with AK. You want to play AK against AQ, AJ, AT or KQ or KJ, if you believe your opponent has one of those hands then flat call, but against an early raisor i would never call. In fact, I only against weak players who will check if they miss the flop......but them again, my style is a bit wayward (remember the KK hand in Blackpool). Maybe get advice off someone else!
