$11: Two 77 hands - too weak?

[mpfree]

Hand #1:

Villian had min-raised earlier OOP and showed KK.

Is this generally a fold anyways this early in the tourney given the action and postion? Or I should have just pushed given my chips?

Preflop: Hero is SB with 7[img]/images/graemlins/diamond.gif[/img], 7[img]/images/graemlins/heart.gif[/img].
<font color="#666666">4 folds</font>, <font color="#CC3333">CO raises to t150</font>, Button calls t150, <font color="#666666">2 folds</font>.

I was going to shove if button didn't call CO's raise. CO was raising margninal hands.

Is the fold correct once button calls, or do I have to push anyways.

Thanks.
