BDG Jorge Quinones - Andreas Husemann

The most popular BDG Declined variation is the Vienna which begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 Bf5. Diemer often played 5.fxe4 (5.g4 is also good.) 5...Nxe4 when we come to the main line Blackmar-Diemer Gambit Vienna 6.Qf3 Nd6 7.Bf4 variation.

In the game between Jorge Victor Quinones Borda and Andreas Husemann, both sides castled queenside. White was pushing for activity on the kingside when all of a sudden he saw an opportunity with 21. Bxa6!, followed by a successful attack on the Black king.

Luis Ledesma French Defence Sawyer

Back in 1989-1991 I tried to play the Blackmar-Diemer Gambit at every opportunity with the White pieces, if Black avoided it with a move like 1.d4 Nf6, then I went with either 2.Nc3 or 2.f3. That way I could still transpose back to the BDG if Black played 2...d5. When Black did not co-operate, I tried to create something original.

I invented the French Defence Sawyer Variation that combines 2.f3 with 4.Bg5 while holding back Nc3 for at least a move or two. Luis Ledesma delayed ...Be7 a move, but castled 6...0-0 quickly. Against Luis, I just developed toward the center and kingside. After Black allowed a pawn fork, I turned down the win of a piece to play for checkmate.

For the next several months I will be posting games from my 10 sections of the 1989 USCF Golden Knights Postal Chess Tournament. I have done about half of them so far this year. As I recall, if I failed to score 4.5 out of 6 games in a section of the preliminary round, then I was dumped from the Golden Knights to the Golden Squires (SS) event for the Semi-Final round. The next month or two will include games from those events.

Sawyer (2032) - Ledesma (1694), corr USCF 89SS40, 11.02.1991 begins 1.d4 Nf6 2.f3 e6 3.e4 d5 4.Bg5 dxe4 [4...Be7 is the most common reply.] 5.fxe4 Be7 6.Nc3 0-0 7.Nf3 b6 [Houdini 3 and Fritz 13 think Black should play 7...h6 8.Bxf6 Bxf6 9.e5= when White's Nf3 is at the moment looks better than Black's Bc8.] 8.Qd2 Bb7 9.Qf4 [Wandering closer to the Black king just to see what might happen...] 9...Bd6? [A tactical error. Logical is 9...Nbd7 10.0-0-0=] 10.e5 Bb4 11.Bxf6 gxf6 12.exf6 Kh8 13.Qh6 1-0
