Chess publisher Bob Long wrote: "I am impressed with this book. ...Mr. Sawyer's section on the BDG Avoided, chapter one, is one of the best repertoire systems you will EVER find on the treatment of the play of center pawns and transpositions---EVER!"
Chapter 1 covers the BDG Avoided. The BDG proper is 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3, when the f3-pawn will be either Declinded (Chapter 2) or Accepted (Chapters 3-7). If Black does not play 3...Nf6 or 2...dxe4 or even 1...d5, then we have a BDG Avoided.
My game with Ron Ferenchak had the distinction of being "Game 1" in my original Blackmar-Diemer Gambit Keybook, published by Bob Long and Thinkers' Press in Februay 1992. I wrote the book over a three year period from late 1988 to October 1991. Ferenchak offered a Benoni. The BDG player often plays Nc3 in front of the c2-pawn.
