A 10 on bubble vs bigstack... push?

[Beavemonk]

$10+1 Read on bigstack is that he has been very conservative on the bubble, even with the bigstack.

Beavemonk....?

I am very insecure about my bubble play because I'm new to SNGs and im learning. My thinking is that i probably have the best hand. Ive seen calls from 22+, Ax, Kx, Q8+ here so I'm a 60/40 favorite if he does call. Since he's the bigstack the chances of him calling are greater, but he hasnt called all-ins from teh shorter stacks until now, but he has moved in himself. I havent put myself in a very good position so far. The blinds will come around to the other 2 shorter stacks, and if they make it through their next blinds I'm thinking all of a sudden I have a lot more pressure. Having said that Im thinking maybe this is the best shot i'll get to steal the blinds, since i have to go through the bigstack to steal any blinds at this point anyway. Is this one of those spots where i simply wait and hope somebody else busts before me?

Even if he's calling with the best 60% of hands this is a +0.7% push.

60% = 22+,A2+,K2+,Q2+,J5o+,J2s+,T7o+,T5s+,98o,96s+,87s


One thing that has really helped me with SNG Power Tools is playing (i.e. pushing) from the SB
