Was going through my old hand histories and found this gem. Obviously it is push/fold. How much of a mistake was this?

[JuntMonkey]

It would depend on Villain, but I'd almost always push.

Since you have 11 BB, I wouldn't call this a huge mistake, but I'd definitely push here. Even if he's raising with 99+, AJ+ and calling your push with all of them, you're in decent shape. Add in that you have at least a little FE because of the bubble (although 4x raises never seem to fold), and the fact that he's probably raising lighter than that, and you have a solid push.
