Blackmar-Diemer Playbook 7

My new Blackmar-Diemer Playbook 7 is a chess opening gambit repertoire guide. The 200 diagrams illustrate one unified plan for White. Each position is followed by a brief explanation or continuation.

Lines in Playbook 7 include Teichmann Exchange 7.Qxf3 c6 8.g4, Euwe 7.Qd2, Bogoljubow 6.Bg5, Vienna 5.g4, Lemberger 4.Nge2, and Huebsch 5.Be3. Lines in Playbook 6 include Teichmann Exchange 7.Qxf3 c6 8.Be3, Euwe 7.Bd3, Bogoljubow 6.Bc4, Vienna 5.fxe4, Lemberger 4.Nxe4, and Huebsch 5.Bc4. Most of the Playbook 7 differs from Playbook 6 although some introductory diagrams are the same.

Below is a Blackmar-Diemer Huebsch Gambit. Marko Hofmann wins against Jan Dette. White gets a strong attack. Black goes wrong in complications.

My new books Blackmar-Diemer Playbook 6 and Blackmar-Diemer Playbook 7 are available in both digital and paperback.]
