Blackmar-Diemer Games 5 Book

My Blackmar-Diemer Games 5 book has just been released. It includes 155 more BDG games mostly from 2016 and 2017. This book was planned to fill a hole in my BDG collection. Four books are in my Blackmar-Diemer Series: Books 1-4. I hope to have a second Series II collection soon with Games 5, the BDG Puzzles book, and Playbooks 6 and 7. If you already have those books and just want Games 5, it's now available in Kindle digital eBook, in Kindle Unlimited, and in paperback.

“Leveller” played a Blackmar-Diemer Lemberger Counter Gambit against “chessabc” on the Internet Chess Club. The chances are equal after Black’s move 3...e5. White responded very naturally by pushing with 4.d5. For those not familiar with this position, the fourth moves most favored by top BDGers are 4.Nge2 or 4.Nxe4. White remained a pawn down but did win the Exchange. The position was complicated when Black ran out of time. If the game opens up, White rooks could cause trouble for Black’s knights.

Aim At King in Philidor Defence

Ray Haines defeated a Philidor Defence in a recent game. White's human approach was to focus on the kingside and virtually ignore the queenside. His single minded focus was rewarded with checkmate on move 36. This whole situation kind of reminded me of driving down the road with your kids squabbling in the back seat of the car. Your focus is on the main task of looking ahead and driving safely. You may know stuff is going on in the back seat, but if it isn't too terrible, you just keep driving ahead to your goal. Gambit play can be like this. In many a Blackmar-Diemer Gambit, my opponent is chopping off a stray pawn or two on the queenside while I am lining up a checkmate on the kingside.

[My Philidor 2.Nf3 Playbook recommends a plan for White after 1.e4 e5 2.Nf3 against 2...d6, 2...d5, 2...f5, 2...f6, 2...Bc5, and 2...Qe7.]

Sicilian Defence Sozin vs Sogin

Who was Sozin? The Russian master Veniamin Innokentevich Sozin was an opening theoretician. He was born in 1896 and died in 1956. Sozin is known for the line 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Bc4 e6 7.0-0 Be7 8.Be3 a6 9.f4. The name “Sozin Sicilian” may mean any classical line with 6.Bc4. Black may have pawns at d6, e6, and a6. Black’s knights may be at Nf6 and at Nc6 or Nbd7. Master Sozin castled kingside and pushed f4-f5 to attack e6. Bobby Fischer played 6.Bc4 with great success.

Lou Sogin was an active postal chess player from the 1960s to the 1990s. Sogin was often on the losing side in those games. I played the Sozin against Lou Sogin in APCT. Note that I played 7.Bb3 to avoid the pawn fork. On move 13 he dropped a piece.

Attack Against The Grain in KID

Gunter O. Heinrich of Denmark played 7.d5 in the King's Indian Defence Saemisch Variation. As White, I usually play 7.Nge2. The blocked pawns allow Black to expand on the kingside and White on the queenside. Heinrich had a different plan. White castled queenside and opened up the kingside against the grain. Such a sharp approach was rewarded by his attacking skill. The bad side of my space advantage after 11...f4 was demonstrated by White’s move 15.g3. I had played some other games where I survived and even won as Black when I allowed an open g-file. But in this case, White was far more ready to use the file. I activated my queenside at the risk of allowing White a passed d-pawn. My game limped along until I accidentally dropped my e-pawn. Two protected passed central pawns was too much for me. I threw in the towel.

There was no sense spending a small fortune on international postage to continue a game that I would almost certainly lose. White performed like the master he was. We played in the large World Tournament Master Class section WT/M/GT/156. The 15 player postal event had us playing all 14 opponents at the same time from early in 1984 until 1988. A decade later I won a different ICCF Master tournament, but that was not this time. G.O. Heinrich ended up with an ICCF rating of 2287. My ICCF rating is 2157.

Anti-Larsen Chess Opening

Dick Zdun chose a rare defense to Larsen's Opening with 1.b3 f6!? George Koltanowski and Aron Nimzowitsch played 1.b3 several times in the 1920s. Bent Larsen made 1.b3 his own playing it over 30 times from 1968 to 1972. Dick Zdun played 1.b3 f6!? It is better to play 1...e5 as Black and later defend e5 with ...f6 if need be.

This 1...f6 reminds me of a Saemisch Kings Indian Defense in reverse. It becomes difficult to safely play a pawn to e5. White took aim at e5 with 2.f4, 3.Nf3, 4.Bb2 and 5.d4. That might be overkill on White’s part. After all, Black need only to play the other central pawn. If he had played instead 6…d5 Black would have had equal chances.

[Rare First Moves is one of five books in my Chess Games 1.d4 Series box set.]

Haines Wins a Sicilian Defence

The Sicilian Defence English Attack 6.Be3 is a race. Players castle opposite sides. They rush to push pawns and to attack targets. It makes for exciting chess. Compare this line to running a mile. It is easy to start well. Most can run hard for the first 10 yards, the first 100 feet, or the first 100 yards. Then we feel tired. We want to take a break and rest.

Ray Haines sent me a Sicilian Defence game from the Houlton Open. Ray writes, “I was black against Roger Hardison. I won the game, He traded Queens early, but I still had a lot of play. He made two big mistakes losing a piece each time.”

Thanks, Ray. That sums it up. After 10 moves most attackers prefer 11.g5 or 11.h4 as Roger Hardison played last time. Here White chose the slower 11.Rg1. It's not a blunder, but it seems like a waste of time. The rook might be better on h1 than g1. When White played 13.Qb6, his intention to swap queens made it clear that he no longer intended to attack kingside. There are easier paths to an even endgame than the Open Sicilian. The game result was still up for grabs until White’s position fell apart tactically.

Hardison - Haines, Houlton ME (2), 05.08.2017 begins 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Be3 e6 7.f3 Be7 8.Qd2 a6 9.g4 Qc7 10.0-0-0 0-0
