Checked around.

I bet 3, 1 fold, villain minraises to 6, one fold, I raise to 12, he raises to 39 leaving himself 18 behind I think.

First off, my raise to 12 was too small right? I was surprised to see this in the HH, don't know what I was thinking. Should I just push? Raise to 35 or so?

And WTF to do now?
