Missed vs Jack Shaw Pirc Defence

Before it became so popular, I often played the 150 Attack when Black wants to avoid the Blackmar-Diemer Gambit with a King's Indian Defence set-up. Because I held back my c2 pawn, the opening transposed to the Pirc Defence. In the second round of the 1989 USCF Golden Knights Postal Chess Tournament my opponent Jack Shaw played 5.Be3 c6, which theoreticians often recommend over the far more popular 5...0-0. In an earlier round game Jack Shaw had defeated my Latvian Gambit.

When I started this multi-year postal event, I was very eager. I entered ten sections giving me 60 games going pretty much at the same time, in addition to the other games I was already playing. As I completed games I moved to the next round giving me another 60, often against stronger opponents. In my spare time I was writing my original Blackmar-Diemer Gambit Keybook. By 1992 the book was published (exactly 22 years ago today!), I was worn out. It looks like in this game I offered a draw in a winning position.

Van Oirschot Caro-Kann O'Kelly 4.f3 c6

30 years ago I tried to back into a Blackmar-Diemer Gambit in a postal chess game played vs Kees Van Oirschot from the Netherlands in the International Correspondence Chess Federation. Kees van Oirschot was a few years older than me. We ended up with a BDG / Caro-Kann Defence hybrid called the O'Kelly Variation. White usually chooses sharper lines such as 5.Bc4 or 5.fxe4. My 5th move 5.Nxe4 is fully sound, albeit rather boring. After our 6th moves, White's awkward f3 pawn is compensated for by Black's doubled f-pawns. The position was very equal throughout. After 13 moves in a very even position, we agreed to a draw rather than play out this game at the rather slow and expensive snail mail pace of international post at the time.

Sawyer - Van Oirschot, corr ICCF 1985 begins 1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 c6 5.Nxe4 Bf5 6.Nxf6+ gxf6 [6...exf6 7.Bd3=] 7.c3 e6 8.Bf4 [8.Ne2!?=] 8...Bd6 9.Bxd6 Qxd6 10.Bd3 Bg6 11.Ne2 Nd7 12.Qd2 0-0-0 13.0-0-0 Rhg8 1/2-1/2

Micah Alekhine 3.c4 Chase Variation

In the Alekhine Defence Chase Variation, generally Black does not quickly push both his center pawns. His play is simple, but the cramped nature of the position can make communication between Rh8 and Ra8 difficult. My ICC game vs Micah starts well, but a tactical mistake on move 23 gives White a winning position. Beware of Black weak points on the kingside. The pawns are not easy to defend, and moving them leaves holes where White could invade as in the game below. Fortunately for me in a two minute bullet game my opponent Micah also overlooked some good moves.

Micah - Sawyer, ICC r 2 0 Internet Chess Club 1997 begins 1.e4 Nf6 2.e5 Nd5 3.c4 Nb6 4.c5 Nd5 5.Bc4 e6 6.Nc3 Nxc3 7.bxc3 [7.dxc3 Nc6=] 7...Bxc5 8.d4 Be7 [Deep Rybka 4 likes 8...d5!? 9.Qg4 Bf8 10.Bd3=] 9.Qg4 g6 10.Bh6 c5 [Or 10...d5= ] 11.Nf3 cxd4 12.Qxd4 Nc6 13.Qf4 d5 14.Bd3 Qa5 15.0-0 Bd7 16.Ng5 Bxg5 17.Bxg5 Qxc3 18.Bf6 Rf8 19.Rfd1 Qd4!?

French to Blackmar-Diemer Weinspach

What chess opening sounds like a Wine Patch in France? It is the cross between the French Defence and the Blackmar-Diemer Gambit known as the Weinspach. The traditional move order would be from a French Burn Variation after 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 dxe4 and now 5.f3!?

In the game below Black "eldee" could reach a BDG Euwe with 5...exf3 6.Nxf3. Black has two good alternatives to decline the gambit at this point by developing a minor piece. One is 5...Nc6!? The other is 5...Be7 as played by my opponent in a 3 minute blitz game. The theory is presented in the notes. Except for our mutual momentary lapses on move 11, the game is a typical example of a White kingside attack in the BDG.

Sawyer (1909) - eldee (1361), ICC 3 0 Internet Chess Club, 02.06.2012 begins 1.d4 d5 2.e4 dxe4 3.Nc3 e6 4.f3 Nf6 5.Bg5 Be7 [5...Nc6!?] 6.fxe4 0-0 [6...Nbd7 7.Nf3=] 7.Nf3 Nc6 [7...h6 8.Bxf6 Bxf6 9.e5=] 8.e5 [8.Be2!?] 8...Nd5 9.Bxe7 Ndxe7 10.Bd3 Nd5 11.0-0?

Index: Blackmar-Diemer Teichmann 8.Be3

The Blackmar-Diemer Gambit Teichmann 8.Be3 variation was the main line of the entire BDG in my original 1992 BDG Keybook. White develops a bishop and has good compensation for the gambit pawn. With d4 protected, White can focus on completing his development and castling either side. This concludes 20 index postings of the BDG 5.Nxf3 lines. Previous BDG Teichmann index were without 6.h3, with 6.h3, and 7.Qxf3.

This variation begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bg4
6.h3 Bxf3 7.Qxf3 c6 8.Be3:
8...Nd5 9.Bc4 Nxc3
8...Nd5 9.Bc4 e6
8...Nbd7 9.0-0-0 e6

8...e6 9.Bd3 and now:

9...Bd6 10.0-0 Nbd7 11.Ne4 Be7
9...Bd6 10.0-0 0-0 11.Ne4 Nxe4 12.Qxe4 g6 and now:

Roecker Storms King Budapest Gambit

During my 20 years of APCT correspondence play, I met many interesting opponents via our weekly postcards. One player that I liked right off was John Roecker. We qualified for the Finals due to success in the previous round. Though I never dared to play gambits in the 1970s, I liked to watch others go for it. John played the Budapest Gambit in a tricky manner. I chose an aggressive approach with the early moves e4 and f4. While the early opening was sharp, the change in evaluation was slow. I did not make any big blunders. I just gradually got outplayed month after month.

I assume this game was vs John G. Roecker that the USCF lists as rated 1988 from Illinois, especially in view of the fact that the APCT owners James and Helen Warren were from the Chicago area, as were many APCTers. Note: John Roecker is not to be confused with Al Roker, the famous NBC weatherman married to Deborah Roberts. The last names are spelled differently. I stopped watching any NBC network about a decade ago when I had cable TV. Cable got too expensive so I went back to rabbit ears; NBC is the only network I do not receive. But I do listen to NBC sports radio. Anyway, Al Roker still makes occasional internet trends news. Al Roker is easy for me to like.

Sawyer (1900) - Roecker (1982), corr APCT 77RF-6, 06.1978 begins 1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 4.e4 h5!?

Greg Conlon Solid Scandinavian Defence

The Scandinavian Defence always has its supporters as it is easy to play and very logical. Early computer programs would play this Center Counter Defence vs me in the 1970s, but of course back then they were very weak by today's standards. This opening is far more popular these days among grandmasters than it was 20 or 40 years ago. Here in the first APCT email Queen section, I take a break from my normal 2.d4!? Blackmar-Diemer Gambit and play the standard 2.exd5. My game vs Greg Conlon shows him defending quite well.

Sawyer (1969) - Conlon (1709), corr APCT EMQ-1, 11.1995 begins 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qa5 4.d4 Nf6 5.Nf3 Bf5 6.Bc4 e6 7.0-0 c6 8.Re1 Bb4 [More common is 8...Nbd7] 9.Bd2 0-0 10.a3 Bxc3 11.Bxc3 Qc7 12.h3 [12.Ne5 Nbd7=] 12...Nbd7 13.Bd3 Bxd3 14.Qxd3 Rfd8 15.Qe2 c5 16.dxc5 Qxc5 17.Bb4 [White could try 17.Rad1 or 17.Bd4] 17...Qc6 18.Rec1 a5 19.Bd2 Nc5 [19...h6=] 20.Ne5 Qe4 21.Qxe4 Nfxe4 22.Be3 Nd7 23.Nxd7 Rxd7 24.Kf1 b5 [24...Nd2+ 25.Bxd2 Rxd2 26.Ke1=] 25.c4 [With 25.Rd1+/= White might have a slight advantage with a bishop vs knight and pawns on both sides of the board.] 25...bxc4 26.Rxc4 Nd2+ 27.Bxd2 Rxd2 28.b4 axb4 29.Rxb4 Kf8 30.Re4 Rc8 31.Re2 Rd5 32.a4 Ra5 33.Rea2 [Or 33.f3=] 33...Rc4 34.Ra3 1/2-1/2
