Diemer Duhm Gambit by Delpire

Jason Delpire sent me this win in a Diemer-Duhm. White played this gambit against the French after 1.e4 e6 2.d4 d5 3.c4. When Black accepted the gambit by 3...dxe4 4.Nc3 f5 5.f3 exf3 6.Nxf3, the game took on the character of a Blackmar-Diemer Gambit Poehlmann (1.d4 d5 2.e4 dxe4 3.Nc3 f5 4.f3 exf3 5.Nxf3 which is also a Dutch Defence.

The Diemer-Duhm difference is the move 3.c4. This helps control the center with pawns, but it delays piece development. White usually prefers to bring out a piece against the French Defence by 3.Nc3, 3.Nd2, 3.Be3, or 3.Bd3. Diemer-Duhm is an excellent choice for the enterprising player in blitz chess. Black lands in unfamiliar territory where threats can easily be missed due to the quick pace of play.

My Queens Gambit Playbook gives White an easy repertoire after 1.d4 d5 2.c4 e6 3.cxd5. Not covered in that book is 3.e4!? which is the Diemer-Duhm Gambit.

The sudden death of my friend and co-worker Ronnie Taylor led me to retire early and use my time to publish 10 more BDG books. They are:

Max Lange Attack by Zintgraff

Gary Zintgraff sent me this background of his attempt to reach a Max Lange Attack:
"Dear Tim: I have always had a fascination with the Max Lange Attack ever since IM George Koltanowski gave a simultaneous exhibition in San Antonio about 57 years ago. He graciously stayed and talked with 3 of us 16 yr. old kids for 2 1/2 hours about all aspects of chess. I asked him why he played the Max Lange Attack so frequently in simuls. His response was that the many traps and tactics allowed him to defeat many of his opponents quickly so he could concentrate on the remaining players. I have mostly had to play the Max Lange from the Black side as few of my opponents enter it when they have Black."
"Here is an ICC game where I have White against a solid opponent who has beaten me a bit more often than I've beaten him. My opponent played the correct move on 4...Bxd4, which leads to the Koltanowski Variation, but makes a mistake at 7...Nxe4? and remains on the defensive. I like taking the e-pawn with my f-pawn as it gives White an open f-file as in the Blackmar-Diemer Gambit. 9.Qf3! would have kept him on the defensive, but I played 9.Qg4? instead. [It seemed like a good idea at the time.] I was able to regain the offensive with his King in the center and got all my pieces developed to finish the game."

[My new Queens Gambit Playbook covers lines after 1.d4 d5 2.c4.]

Isler Wins Blackmar-Diemer 4...c5

Black declined a Blackmar-Diemer Gambit with 4.f3 c5. More common is to accept the gambit with 4...exf3 or to decline by 4...Bf5. The first thought is that at least White is not going to be down material. However in this game, after 5.Bb5+ Bd7 6.dxc5 exf3 7.Nxf3, Black grabbed the gambit pawn anyway.

The battle ensued over c5 and then f4. Benjamin Isler won against Christiane Rommeck in Germany last month. Tactics were missed and mistakes made in complications from moves 17 to 20. Then White found a way to win a knight.

Crompton Wins BDG Teichmann

John Crompton showed me this game and asked, "Tim Sawyer, how or what do you do if on move 16 N7f6?" I agreed that it would have been an improvement for Black. However, White had two earlier improvements of his own. On move 13 the captures on f6 would give White a big advantage. Once that was missed, there was still 15.Rh3 later in the game. We all miss stuff. What mattered most was that White did find a win. He sacrificed a rook to force a mating attack with his queen and two bishops. This is Game 28 in of the 155 games in my BDG Games 5 book which is a mixture of tournament, blitz, and correspondence games.
