Well, sure but if you miss the flop and Cbet with AK instead of J2 for example you've still got the best nothing hand (which might be ahead) and you've always got 2 overs to top pair...so cbetting with AK is at worst a semi-
bluff where betting with J2 is usually a stone cold bluff.
I don't think AK is the nuts or anything, but it can often be played like the nuts. Especially in the mid/late stages of a tourney.
No, you shouldn't get married to AK esp early in a tourney but the same can be said for AA.
