Big balls with AK in a tourney?

[Talking Poker]

Let me give you an example...

Situation #1:
WSOP Main Event. Blinds are 25/50 and you have 10k in your stack. The pot is raised and reraised in front of you, you flat call, the first raiser pushed in and the reraiser calls.

Situation #2:
UB WSOP Freeroll. Winner take all. 850ish players registered. First prize is a WSOP ME seat. 2nd place gets a friendly "Nice try, kid." The players fold around to you on the button, you raise, and the BB pushes in.

Situation #3:
$11 Turbo Single table SNG, 6 max. The players fold around to you on the button, you raise, and the BB pushes in.

Even though you have AK and it's the first hand in all of them, surely you can see how those are NOT the same situation, right?
