Blackmar Diemer Trap Normand

Nicolas Normand played the Blackmar-Diemer Gambit Vienna Variation. His game illustrates a point of theory that I have tended to overlook. This game gives me a good opportunity to examine it. Normand wrote to me. I quote a portion of his comments:

“Mr Sawyer, I am a 40-year-old French chess player. I have been playing chess since I am 15 but in chess tournament for only 3 years. I am a Blackmar-Diemer Gambit player as white especially Ryder gambit. I was wondering if you could give some piece of advice to find the best resources of information to fasten my studying. Of course, I tend to be a fan of Emil J. Diemer, Bill Wall's and Tom Purser's works and games. Maybe we could share some games. I thank you in advance. Nicolas
“PS: I have already most of your books that I enjoy a lot! I am very flattered that one of my games can be usable or even interesting. I have been following your different BDG chess works for a few years and you are a true reference for me (as German language is a bit harder for me, so sorry Emil !).”

Nicolas Normand as "DEATHSTAR81"wins a piece when Black falls into his trap.

Sicilian Grand Prix Attack 5.Bc4

Sicilian Defence Grand Prix Attack 5.Bc4 pressures Wesley So to defend. Watch how Grandmaster So turned the tables and won quickly. How do great players make good players look bad? They keep them busy with little issues so that they miss big issues.

The big issue: White did not move his dark squared bishop at all for the entire game. He could not move it because he never moved his pawn on d2. In effect White gave odds of a rook and minor piece to one of the strongest players in the world. That didn’t work well.

In the Sicilian Defence after 1.e4 c5, White normally plays for d4 on moves 3 or 4 after either 2.Nf3 or 2.c3. The Grand Prix Attack 2.Nc3 and 3.f4 takes control of d5 and aims at f5. White pressures Black to defend against a strong attack. Remy Degraeve did well enough that if he taken the bishop 23.cxd4 on his next move, he would be ahead a rook and minor piece. That's hard to do! Then he would get checkmated. That's easy to do.

Grob Attack Delayed Spike 1.g4

Jocelyn Bond of Canada wins a Grob Attack. 1.g4! is one of those Rare First Moves. About 20 years ago I played the 1.g4 Grob and 1...g5 Borg (Grob backwards) many times. My most memorable experiences were the four games that I played against the infamous Claude Bloodgood. He was finishing out his life sentence in prison.

Here Jocelyn Bond played the White pieces. The game has a little Spike Attack (g4-g5) flavor. Usually the Spike is 3.g5 in response to the threat of ...Bxg4. Black's solid move 1...e6 makes no attempt to attack or punish the g4 pawn. Jocelyn Bond wrote:

“Hi Tim, I just played a nice Grob opening game as white. Can you publish this? It’s blitz but I enjoyed so much to have played this game! Thanks a lot and come and play black against my Grob.”

Ruy Lopez Riga Tricky Line

The King Pawn Open Ruy Lopez Riga line is tricky for club players. White sacrifices his e4 and d4 pawns for an attack. White threatens to win a piece while Black has a counter attack. In a prior game against the Riga from 1979, my opponent played 8…Bd7. I got his knight and won that game in 45 moves. This line gets its name from a correspondence match between the city of Berlin in Germany and the city of Riga in Latvia. Black won an ending where White had an extra knight, while Black had three extra kingside pawns.

In the 1980s I played in several an ICCF Master Class events. They allowed players to become a master or to compete in the World Championship cycle. That cycle used to take about 10 years of continuous winning. A grandmaster would win in the end, but we all had hopes and dreams. One of my opponents was Albert Maier from Austria. In 1994 Maier reached his peak ICCF rating of 2152. Our 1984 ICCF game was an Open Ruy Lopez Riga Variation. Because it was postal chess, we had access to chess books.

Albert Maier as Black followed the original Berlin vs Riga game for 17 moves. That game continued 18.g5 Rag8 19.Bd4 h6 20.Bf6+ Kf7 21.Bxh8 Rxh8 21.Rd1 hxg5+ 22.Kg2 Kf6. Instead, I varied with 18.Kg3. I got a good position and won in 25 moves.
