Did I play my AK Suited right in this situation?

[jj_frap]

Scenario: Very early in $5 buy-in 8 handed tournament at a local pub, blinds at $25/$50.
The cards are dealt and I receive AKs (diamonds).

UTG, UTG+1, and UTG+2 fold to Button-2, a calling station who limps into the pot for the first time all night.

I raise to 4xBB

The button, a newcomer to the pub with two years of RL and Internet experience who routinely crushes online small-stakes games and typically plays cash no-limit and has read a lot of books about every variation of the game, calls my raise, as does Button-2. The blinds fold.

Flop comes up Ks, 3c, 9h, giving me top-pair with the best possible kicker.

Button-2 opens the betting at $500, or 5/6 of the pot, increasing it to $1100.

I see her bet and raise her another $500, making the pot $2100.

The semi-shark, either a tight player or a player with a tight table image, goes all-in.

Button-2 calls without thinking, and I pause for about 30 seconds to consider the possibilites and call as well.

Did I make the right play?

RESULTS BELOW. DO NOT READ IF YOU WANT TO COMMENT WITHOUT BIAS.

We show our cards, and Button-2 has pockets 7s, I have big slick (as I said before), and my opponent has bullets.

His aces hold up and I'm out of the tournament, breaking my two tournament winning streak that followed a four tournament slump which followed a run where I 3 tournaments and lost another to a maniac in heads up.

Hmm, you won't get a good response unless you can also post the stack sizes.

Either a call or fold can be correct depending on your pot odds.
