Quick PF Hand...

[MrFeelNothin]

$50 Party SnG, 7 remaining, blinds 100/200, stack sizes:
BUTTON(1260)
HERO-SB(1230)
4 folds, BUTTON raises(400), Hero(A /images/graemlins/diamond.gif9 /images/graemlins/club.gif)....?

I like my chances of having the best hand here, but is it worth it to back my stack on since a laydown to an all in raise by me isnt too likely?

If it makes a difference, all the stacks were pretty even, biggest being t1865, smallest t1038.

I decided I likely had the best hand here and moved in. I was very surprised to be called by A7. Considering that I'm not getting any better hands to lay down here, how often do I have to be called by a lower A to make this play ok. If hes calling with A7, are there any hands he would raise, then fold? Im thinking maybe not, and putting my chips in when there is no chance of my opponent folding is usually what I try to avoid.
