I call 3 1/2 times BB raises with position consistently

AK usually plays best either all-in or for about 10% to 15% of your stack preflop so that you deny small pairs implied odds and can get your stack in with at most 2 bets - ideally by raising or check-raising all-in. If the effective stack is somewhere in the 50 to 100 BBs range, this means that you should often reraise preflop, otherwise you'll suffer negative implied odds.

If you have to make trap-plays, then make them with big pairs so that you can get paid off by top pair/best kicker if you flop an overpair. AK is a lousy trap hand as it's the first hand you will be put on when you give serious action on a king- or ace-high flop.
