Yace is No in Blackmar-Diemer Vienna

The Blackmar-Diemer Gambit game that I played vs Yace Paderborn was in a test line of the BDG Vienna 4...Bf5 that helped me focus on the advance of the kingside pawns. This seemed to discourage the silicon opponent from castling on the side and instead slither off to the queenside. No matter. I managed to outplay it anyway. The opening is a critical variation where Black sets up a solid defence of the vulnerable f7 and b7 squares with moves like 6...Nd6, 7...e6, 8...c6 and 9...Bg6. But Black cannot hide forever.

Sawyer (1931) - Yace Paderborn (1967), Florida, 21.04.2010 begins 1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 Bf5 5.fxe4 Nxe4 6.Qf3 Nd6 7.Bf4 e6 [7...Bxc2] 8.0-0-0 c6 9.g4 Bg6 10.h4 h5 11.g5 Nd7 12.Bd3 Nf5 13.Nge2 Qb6 14.Rhf1 Nxh4 15.Qg3 Nf5 16.Bxf5 Bxf5 17.Qf2 0-0-0 18.Ng3 Bh3 19.Rfe1 Bb4 20.Nge4 e5 21.Be3 Bg4 22.Rd2 Nb8 23.dxe5 Qc7 24.Rxd8+ Rxd8 25.Bf4 Bxc3 26.Nxc3 b6 27.e6 Qe7 28.Bxb8 Kxb8 29.exf7 Qxg5+ 30.Kb1 Qf6 31.Qxf6 gxf6 32.Re8 Rc8 33.Rxc8+ 1-0

Blackmar-Diemer Poisoned Pawn 8...Bxc2

In the Blackmar-Diemer Gambit there is a wild BDG Ziegler 8...Bxc2 line which is like a Poisoned Pawn line. How ironic it was that my opponent "PoisonPawn" grabbed that pawn in a three minute blitz game last year. I know the first dozen moves of this variation pretty well, but at a speed of 2-3 seconds per move, I miss stuff a lot. Nowadays theory favors the solid retreat 8...Bg6 as Black's only chance for advantage.

Our game shows the real vulnerability of the Black king in this 8...Bxc2 line. That marked monarch is caught in the middle and under assault from all the remaining White forces. Computers usually find wins for White in this Blackmar-Diemer Gambit line, but humans may or may not depending on knowledge, tactical skill, pattern recognition and time to calculate. I won quickly but could have won even quicker.

Sawyer (1903) - PoisonPawn (1962), ICC 3 0 Internet Chess Club, 20.09.2014 begins 1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 exf3 5.Nxf3 c6 6.Bc4 Bf5 7.0-0 e6 8.Ng5 Bxc2 9.Nxf7 Kxf7 10.Qxc2 Qxd4+ 11.Be3 Qxe3+ 12.Kh1 Bc5 [12...Be7 13.Rae1+/-] 13.Rae1 Qh6 [13...Qd4 14.Ne4+-] 14.Bxe6+ [14.Rxe6!+-] 14...Kf8 15.Ne4 Be7 16.g4 [16.Qb3+-] 16...g5 17.Rf5 [17.Nxf6!

Tactical Shot Keres Sicilian Haines

I found this game I played vs Ray Haines from 40 years ago in the Sicilian Defence. We played a Keres Variation and Ray was outplaying me as usual when all of a sudden I found a tactical shot that immediately turned the game into an instant win for me. The finish reminds me of tactical puzzles I solve daily with Chessimo that are based on the final moves of many master games.

Ray Haines has been my best friend in Maine for 40 years. We have constantly stayed in touch. Back then we were in those exciting early days working our way up through the ranks of chess players in Maine. After a year of playing face to face with Ray Haines, I moved away and returned to college. So we played postal chess.

Here I chose the 6.g4 variation made famous by Paul Keres. After some inaccuracies, I missed the brilliant win with 13.Na3! For 15 moves Black was better. Then Ray missed my 29.Nf5! which leaves my queen and knight en prise and wins by force for White.

Sawyer - Haines, corr 1975 begins 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.g4 Nc6 7.g5 Nd7 8.Ndb5 [The main line is 8.Be3 Be7 9.h4+/=] 8...Nb6 9.Bf4 [9.Be3] 9...Ne5 [9...e5=] 10.Qh5 g6?!  [10...Ng6=] 11.Qe2 a6 12.0-0-0 Nbc4 13.Bxe5?!

Sawyer in 1.e3 Alapin French Reversed

In 2014 I goofed off playing risky openings vs lower rated players for fun. Sometimes the temptation was just too strong. After White's move 1.e3, we head for a French Defence reversed. When White wasted a tempo by 2.a3?! I chose an aggressive gambit strategy. Obviously 3...Nc6 is good, but I was in a mood to play an Alapin French Reversed.

Black planned to use the f-file in Blackmar-Diemer style for a kingside attack. Instead of setting up a solid defense, White advanced his own f-pawn. Briefly chances were even. Then the tactical tide shifted and White was swept away with checkmate.

Coiled Spring in Jamison English Opening

Larry Jamison plays the English Opening 1.c4 while holding back d2-d4 with the opportunity to bust open the center at a later moment. Alexander Kotov in his book "Train Like A Grandmaster" calls this method of opening strategy the coiled spring.

On pages 12-13 we read:
"Sometimes grandmasters will decide to avoid the deeply studied book lines by using a method that reminds one of a coiled spring. They make just one pawn advance to the centre, fianchetto the bishops and allow the opponent to occupy the centre. The calm here is apparent since just one incautious pawn advance by Black and White's pieces will uncoil with great force and inflict damage on the enemy."

That is the plan. But if a coiled player never springs forth from his compact position, then he goes from being a potential threat to being a contained target.

I responded with a Dutch Defence 1...f5. Chess engines show I should have equalized on move six or seven as noted. Instead, my pieces got tangled up. I was fortunate White did not force more open lines quickly. Given enough time, I mounted a winning attack.

Guest Gruenfeld Defence without 3.Nc3

When White delays 3.Nc3 in the Gruenfeld Defence, there is the possibility of kicking the Black knight off d5 without allowing it to chop off the horse on c3. Here my "guest" opponent plays quite well. I gave him or her a fake rating of 1600, but that might be off by a few hundred points.

For purposes of calculating my performance rating over thousands of games, I often make up a rating for unrated opponents based on how hard I feel they pushed me or how much they let me get away with. It is purely subjective, but based on 50,000 games of personal experience. My own Internet Chess Club rating has been creeping upwards this year to 2081 in this game.

Powerful New Blackmar-Diemer Move

The Blackmar-Diemer Gambit has many variations that can quickly lead to wide open tactics at a moment's notice. Here in a BDG Teichmann, Black's 8th move allows me to illustrate a move that I found while writing my upcoming BDGK4 book which I hope will be out later this year.

Chess engine analysis in 2015 reveals that White has 9.Rh2! which a new and powerful response that leads to a big advantage. I missed it in this blitz game, but I can still pass it on to you here.
