Deep in a PS 3+R

[Quercus]

1500 or so runners, down to final two tables. My stack is around average. I'm probably 6th or 7th of 13.

I didn't play many hands once we got down to 2 tables, and I felt like I probably was too passive.

My table image has been tight. I've shown down nothing but solid hands and I've not been involved in many pots.

Couple hands:

CO in this hand is a good tournament player. He's been accumulating chips by pushing all-in against limps and weak raises.

My stack is ok, but the blinds are rising soon and merciless. Table is tight because of the impending FT bubble. A8o too light to raise here in this situation or am I a donkey for thinking of anything but a raise here?

<font color="#666666">3 folds</font>, Button calls t40000

Button has been limping when folded to him on the button every single time. BB has seemed like a fine player. Call, 3-4x raise, or push here?
