It is curious a NM seems most worried by 1...b6 against 1.e4.
Is there a sharp line I can use against 1...b6 if I play 1.e4?

In the first comment , but ok is really a problem to get sharp play against 1e4 b6, as opposed to anything else.

Guess it's true american's don't do irony, even used an emoticon as clue wasn't being serious lol.
As another wild guess maybe he said what is in title of thread

I faced the Owen Defense once in the game below where I decided that if my opponent didn't want to control the center and threaten my position I would do it - my same attitude against the Modern Defense or Pirc Defense. I started a Pawn Storm right up the middle, won a piece, got greedy and sloppy and ended up losing the game. But the opening idea is, I think, sound:
c5? is a well known error for black in this. the natural d5 is what should be played.
Owens blows ... early d5 by white blows it all to smithereens
