A couple things that you don't detail come into play.

The size of the "smaller stacks" as mentioned previously. Are they close to the wall or are they close to you.

You say the villain is not a maniac, but will he lay down if you push back?

If the stacks are about even, I lean towards shove. If the short stacks are in eminent danger, I lean towards fold - I have nothing invested in this hand so far.

If the villain might lay down, I lean towards shove. You're probably ahead but facing 2 over cards makes you a very slight favorite and general tourney strategy suggests to avoid slight edge situations with a lot at stake. The gap theory also suggests a probable fold.

Also to consider: will the blinds jump into the mix? Your shove would likely make them fold (if they hane any clue), but your fold might induce them to play sherrif.
