Over calling with a chip lead

[ChuckNorris]

This is 100% dependant on your opponents. You should have some reads on them when ITM. I don't know about your usual sit'n'gos, but in the average low/medium buy-in party s'n'g I would just push here.

I don't see why you would want to call here. If you think you have the best hand, you should push to try to win the pot instantly (of which you should have a decent chance) or at least to get it heads-up (which is almost certain if you push, as SB will of course fold almost everything if button calls). Why on earth would you call and let them outdraw you?

If your opponents are incredible rocks and you're sure they have AJ or better then go ahead and fold.
