And I'm sorry to hi-jack...next time I'll read the entire thread before commenting so I can consolidate.

If you understand that 10BBs is ATC territory for an unraised button, you should be able to grasp the 15BB shove into 35BBs as well. It's virtually the same thing.

And while it's true that sometimes you need to push the smallest edges, remember that when you get it all-in with an 85/15 edge, you are going to lose 15% of the time. If the field is so weak that you know you can consistently pummel them, then perhaps risking getting busted 15% is worth avoiding. An idiot on this hand will still be an idiot on the next hand, and luck runs both ways.
