LVL 3, $22 -- 2PR vs (BS?) push from BB...S.O.S.

[Floyd Moseby]

Blinds are 30/60 on a $22 NL SNG on PP...don't have much of a read on anyone yet, haven't really seen any remarkable play one way or the other. I know I'm going to get several "fold pf" comments, but I don't normally mind limping in LP like this (earlier in a tourney) unless I strongly suspect a reraise behind me. That wasn't the case here. I try to see flops cheaply with low suited aces, and then play aggressively with them after the flop if I see a spot open for me (I try not to spew chips vs heavy resistance). Leaky?

Anyway, what's my play here?
