playing pp with overcard pair on flop

[Zaebos]

I guess this is a newbie question but this is my first post so:
If you have KK and the flop comes with two aces and a blank how much differently, if at all, do u play your KK. Also what are the chances that another player was dealt the third ace? If first to act on flop would u bet for information and because you showed strength early on or just check because of the scare cards? Also how would you play if you were second to act on flop and it was bet or checked to you?

Thanks in advance

check/fold.

you're goal in SnG is to make it to top 3. play tight. if you don't think you have top hand on the flop, fold.

you had a bad flop. lay down those kings. it's part of the game.
