20+2 To be or not to be (a wuss on the bubble).

[Matt Walker]

I think it is extremely bad to fold here. Even if someone ran an ICM and said it was wrong to call given his range, I still do it. Look at the stacks if you call and win:
Button (t1230)
SB (t1320)
BB (t710)
Hero (t4740)
Can't you see why this is extremely in your advantage? ICM doesn't take this into consideration.

Besides this I think there is a good chance you have him dominated. Hed have to be a complete rock not to push aq and ajs there.
