The Grob

There is a chessbase file for free at chessville.com that covers the book 'Tactical Grob'. It has many attacking lines in it. I use the Grob frequently in blitz games and score fairly well with it. Mainly from the lines in the book. If you search the forums there was a previous post about the Grob giving the link to this file. Unfortunately I cannot post the link at this time. Maybe when I get to work.
Boog

I put 421 Grobs on my home page at http://www.geocities.com/SiliconValley/Lab/7378/grob.htm
I wrote a book on it a few years ago. I may need to update my file.
I have recently taken a liking to the Grob opening, 1. g4, and I want to know if anyone has any tips or strategies that they would like to share for either black or white.
