Elephant Gambit by Tom Purser

Once upon a time Purser talked to his private investigator buddy Peter Atzerpay about the opening 1.e4 e5 2.Nf3 d5. Peter asked if the opening was called either “Queen's Pawn Counter Gambit” or “Mittelgambit im Nachzug”. But Purser called it, “An Elephant.”

When Tom Purser passed away, I was reminded of how much he enjoyed playing the Elephant Gambit. This opening as Black has some of the same characteristics that the Blackmar-Diemer Gambit has as White. His original book on the Elephant Gambit book was published on July 3, 1988 by Blackmar Press. The authors who compiled this book were Niels J. Jensen, Tom Purser, and Rasmus Pape.

Tom Purser played in an Atlanta tournament in 1983. There Tom won an Elephant Gambit vs “A. Sheehan”. The USCF lists a player from Georgia named Andrew Sheehan. I am guessing that he may have been Tom Purser’s opponent here. I provided my own detailed analysis on this line.

Dutch Defence Wins With Amin

I’m not afraid to face gambits. I like the straight Dutch Defence 1.d4 f5 even though it allows White the Staunton Gambit 2.e4!? Those who play the French Defence 1.e4 e6 2.d4 d5 as Black may avoid the Staunton Gambit with the move order 1.d4 e6. Here Black maintains the choice between 2...d5 and 2...f5. He can make his choice after seeing White’s second move.

The Egyptian grandmaster Bassem Amin won the African Chess Championship three times in 2009, 2013 and 2015. In December 2016 Bassem Amin was the highest FIDE rated player in Africa. As White GM Amin usually plays 1.e4 or a Kings Indian Attack after 1.Nf3. Bassem Amin tends to avoid the most popular lines.

As Black Grandmaster Amin plays a wide variety of openings. Amin has preferred 1.e4 e5 in the Open Games, but that is not a guarantee. Amin is an unpredictable opponent to prepare for. Amin answers 1.d4 with 1...Nf6, 1...d5, 1...f5 or as here 1...e6. Bassem Amin backed into this Classical Variation of the Dutch Defence against Grandmaster Mohamad Al Sayed from Qatar.

Al Sayed (2508) - Amin (2662), World Rapid 2016 Doha QAT (1.32), 26.12.2016 begins 1.d4 e6 2.Nf3 f5 3.g3 Nf6 4.Bg2 Be7 5.0-0 0-0 6.c4 d6 7.Nc3 Qe8 [7...Ne4 and 7...a5 are major alternatives.] 8.Qc2 [8.b3 c6 9.Qc2+/=] 8...Qg6 [8...a5 9.Be3+/=] 9.Nh4 [9.d5+/=] 9...Qh5 10.Bf3 Qf7 11.d5 c6 12.b3 Ng4 13.dxe6 Bxe6 14.Ng2 Qh5 [14...Ne5 15.Nf4=] 15.h4 g5 [15...Qf7 16.Nf4+/=] 16.Bxg5 Bxg5 17.Bxg4 fxg4 18.hxg5 Qxg5 19.Rad1 Bf5 [19...Qe5 20.Qd3+/-] 20.Qd2 Qg7 21.Qe3 Rf6 [21...Nd7 22.Rxd6 Rae8 23.Qd4+/-] 22.Qe8+ [22.Nh4 Bg6 23.Nxg6 Qxg6 24.Qe7+-] 22...Rf8 23.Qe3 Rf6 24.Nf4 Qf7 [24...Rh6 25.Qe8+ Qf8 26.Qxf8+ Kxf8 27.Ng2+/-] 25.Rd4 [25.f3 gxf3 26.Qxf3+-] 25...Nd7 26.Rfd1 Re8 27.Qd2 d5 [27...Qf8 28.Rxd6 Rxd6 29.Qxd6 Qxd6 30.Rxd6+/-] 28.cxd5 c5 29.Ra4 a6 30.b4 [30.d6 Kh8 31.Kg2+-] 30...b5 31.Ra5 cxb4 32.Nb1 [32.Nxb5 axb5 33.Rxb5 Be4=/+] 32...Be4 33.Qxb4 [33.Rf1 Rh6 34.f3 gxf3 35.exf3 Bxb1-+] 33...Rh6 34.Ng2 Bxg2 [34...Rh1+ 35.Kxh1 Qxf2 36.Qxe4 Rxe4-+] 35.Kxg2 [35.Qxg4+ Rg6 36.Qd4 Bh3-+] 35...Qh5 0-1

Rob Hartelt Caro-Kann to BDG

Rob Hartelt wins a Caro-Kann that transposed into the Blackmar-Diemer Gambit. White had a winning plan that led to a crisp sharp victory. White looks to be having fun! Black used the handle “petrorebro” and was listed as being from the Ukraine. The players were ready for action in this one minute game. Rob Hartelt consistently applied pressure. Black lost on time just before getting mated. White still had 35 seconds left.

When I played both the Caro-Kann Defence and Slav Defence as Black, it made sense to answer 1.d4 d5 2.Nc3 with 2...c6. The natural continuation 3.e4 dxe4 lead to positions that I knew well. I wrote about my own adventures in my book on the Caro-Kann.

In this opening typically White plays 4.Nxe4 when Black has a choice between 4…Nf6, 4…Nd7 and 4…Bf5. I played them all from both sides of the board. Once in a while as Black I faced a bold White player who offered a gambit by 4.f3!? exf3 5.Nxf3 Nf6 6.Bc4. Note that White might arrive at the same position after 4.Bc4!? Nf6 5.f3 exf3 6.Nxf3.

Rob Hartelt is an active player in the Colorado chess scene. I’m sure that he picks up tactical ideas being around so many strong players. One such motif was h4 with the bishop sacrifice Bxh7+ followed by Qh5. It proved to be an excellent practical choice at a fast speed. White’s plan worked here with Black’s cooperation.

This BDG Ziegler 6.Bc4 e6 is section 1.9 in Blackmar-Diemer Games 1 and Blackmar-Diemer Theory 3.

Hartelt - petrorebro, Live Chess Chess.com, 21.12.2016 begins 1.d4 d5 2.Nc3 c6 3.e4 dxe4 4.f3 exf3 5.Nxf3 Nf6 6.Bc4 e6 [6...Bg4 7.Bxf7+ Kxf7 8.Ne5+ Kg8 9.Nxg4 Nbd7 10.Qe2 h6 11.Bf4 Nxg4 12.Qxg4 Kh7 13.0-0-0+/-] 7.Bg5 [7.0-0 Be7 (7...Nbd7 8.Qe1 Bd6 9.Ne4 Nxe4 10.Qxe4 h6 11.Bd3=) 8.Qe1 Nbd7 9.Bd3 c5 10.Be3 0-0 11.Kh1 cxd4 12.Bxd4 Bc5 13.Rd1 Bxd4 14.Nxd4=] 7...Be7 [7...Nbd7 8.0-0 Qb6 9.Rb1 Bd6 10.Qd3=] 8.Bd3 0-0 9.h4!?

Semi-Slav Mamedyarov Wins

Veteran players rated over 2700 rarely lose quickly. Super grandmasters are especially difficult to beat in under 30 moves. Boris Gelfand was born in Minsk, Belarus in 1968. Boris became a grandmaster in 1989. By 1991 he was a World Championship Candidate. Gelfand later emigrated to Israel. He is hard to beat.

Grandmaster Shakhriyar Mamedyarov of Azerbaijan twice won the World Junior Championship. In 2013 Mamedyarov won the World Rapid Chess Championship. In December 2016 he was the 12th highest FIDE rated active player in the world at 2768.

Queens Gambit Semi-Slav Defence 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 c6 5.Bg5 gives Black many options. The main line is the Moscow Variation 5...h6, although the Botvinnik Variation after 5...dxc4 is also interesting and playable. After 5...h6 Black gets the bishop pair and a solid position. White obtains more active central play with extra space and a lead in development.

Mamedyarov (2761) - Gelfand (2743), 10th Tal Mem 2016 Moscow RUS (3.5), 29.09.2016 begins 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c6 5.Bg5 h6 [5...Nbd7 6.e3 Qa5 is the Cambridge Springs Defence; 5...Be7 6.e3 Nbd7 7.Rc1 is the Orthodox Queens Gambit Declined; 5...dxc4 6.e4 b5 7.e5 h6 8.Bh4 g5 9.Nxg5 hxg5 10.Bxg5 Nbd7 11.exf6 Bb7 12.g3 c5 13.d5 Qb6 14.Bg2 0-0-0 15.0-0 b4 16.Na4 Qb5 17.a3+/=] 6.Bxf6 [6.Bh4 dxc4 7.e4 g5 8.Bg3 b5 9.Be2 Bb4 10.Qc2 Bb7 11.0-0 Nbd7 12.Rad1 Bxc3 13.bxc3 c5=] 6...Qxf6 [6...gxf6 7.e3 Nd7 8.cxd5 cxd5 9.Rc1+/=] 7.g3 [7.e3 Nd7 8.Bd3 dxc4 9.Bxc4 g6 10.0-0 Bg7=; 7.Qb3 dxc4 8.Qxc4 Nd7 9.Rd1 g6=; 7.Qc2 Nd7 8.e3 (8.e4 dxe4 9.Qxe4 g6 10.Bd3 Bg7=) 8...Qd8 9.Bd3 Be7 10.0-0 dxc4=] 7...Nd7 8.Bg2 dxc4 9.0-0 Be7 '=' 10.Ne4 Qf5 11.Ned2 e5 12.e4 Qh5 [12...Qe6 13.Rc1 b5 14.b3=] 13.Nxc4 exd4 14.Qxd4 [14.e5=] 14...Qc5 [14...0-0 15.e5 Bc5 16.Qc3=] 15.e5 0-0 16.Qe4 [16.Rad1 Qxd4 17.Nxd4=] 16...Nb6 17.Ne3 Qb4 18.Nd4 Rd8 [18...Bc5 19.Rfd1 Qxb2 20.a4 Bxd4 21.Rab1=] 19.Rad1 Qxb2 20.e6 Bxe6 [20...Bf6 21.Nxc6 Rxd1 22.exf7+ Kxf7 23.Rxd1 bxc6 24.Qxc6=] 21.Nxe6 fxe6 22.Bh3 Kh8 23.Bxe6 g5 [23...Rxd1 24.Rxd1+/=] 24.Ng4 Rxd1 25.Rxd1 Qg7 26.Ne5 Qf6 27.Bb3 Kg7 [27...Rf8 28.Ng6+ Kg7 29.Qxe7+ Qxe7 30.Nxe7+-] 28.Ng4 1-0

Andreikin Wins Napoleon Attack

The main line of the Napoleon Attack is illustrated in Andreikin vs Mozharov. This line looks like a Scotch Game or Scotch Four Knights Game. White has the option to transpose. Dmitry Andreikin is among the top players in the world. Andreikin is a former World Junior Champion. Mikhail Mozharov is a Russian grandmaster born in 1990.

Because of the popular nature of this line I have provided quite a bit of detailed analysis. The move 4…Nf6 is the most common among many fourth move possibilities. When White plays the Queens Knight Attack then positions like this one can be reached frequently. Black has a wide choice of moves but the basic set up is similar. White likely plays it more often than Black, and thus White would be more familiar with the typical tactics and strategy.

Andreikin (2720) - Mozharov (2573), 69th Moscow Blitz Moscow RUS (2.9), 06.09.2015 begins 1.Nc3 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Nf6 5.Bg5 Bb4 [5...Be7 6.Nf5 0-0 (6...h6 7.Nxg7+ Kf8 8.Bxf6 Bxf6 9.Nh5 Bxc3+ 10.bxc3 Qg5 11.Ng3+/-) 7.Nxe7+ Nxe7 (7...Qxe7 8.Nd5 Qe5 9.Bxf6 gxf6 10.e3 f5 11.c4+/=) 8.Bxf6 gxf6 9.e4 f5 10.Qh5 fxe4 11.Nxe4+/-; 5...h6 6.Bxf6 Qxf6 (6...gxf6 7.Nd5 Nb4 8.e4 Nxd5 9.exd5 Bc5 10.Qg4 Qe7+ 11.Kd2+/-) 7.Ndb5 Qd8 (7...Qe5 8.Nd5 Kd8 9.Nbxc7 Rb8 10.Nb5 Qxb2 11.Rb1 Qxa2 12.e3+/=) 8.Nd5 Bb4+ 9.c3 Ba5 10.b4 a6 11.Nd4 Bb6 12.Nf5+/=; 5...Bc5 6.e3 Nxd4 7.exd4 Be7 8.Bd3 0-0 9.0-0=] 6.Nxc6 bxc6 [6...dxc6 7.Qxd8+ Kxd8 8.0-0-0+ Ke7 9.e4 h6 10.Be3=; 6...Bxc3+ 7.bxc3 bxc6 8.e3 h6 9.Bh4 0-0 10.Qf3=] 7.Qd4 Be7 [7...Qe7 8.Bxf6 gxf6 9.e3 Bc5 10.Qh4=] 8.e4 d6 [8...0-0 9.Bd3 h6 10.Bh4 and 1-0 in 97.

French Leaping Knight Mate

I played several openings against Bob Muir with a tendency to gradually move to the right. Most often I began 1.d4. This led to some Queen’s Gambit Declined games as well as some Blackmar-Diemer Gambits. We played a lot over maybe eight years time.

Shifting to right further I played 1.e4 quite a few times with the French Defence and the Ruy Lopez. Once in a while I played the Bird 1.f4. One rare occasions I even played 1.g4, but the Grob is further to the right than I like to go.

His French Defence choice led me to play a typical Tarrasch Variation. We continued 4.exd5 cxd4. The game reminded me of the von Hennig Schara Gambit. That opening begins 1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 cxd4.

Black plays the same exact first four moves. White starts with 1.d4 in both cases. After that he attacks Black’s d5 pawn on move two. White develops a knight on move three. And finally White captures on d5 with a pawn on move four. Soon after the queens come off the board in both openings.

Here Black lost his stranded pawn on d4, although he had some compensation. Black castled queenside. White castled kingside. Then the pieces started flying with attacks threats and counter threats. White maintained the one pawn advantage. Black kicked a White knight, expecting it to retreat. Instead the knight leaped over the pawns for checkmate!

My new French 3.Be3 Playbook is a step by step guide to the Alapin Diemer Gambit.

Sawyer (2010) - Muir (1800), Williamsport, PA 03.1998 begins 1.d4 d5 2.e4 e6 3.Nd2 c5 4.exd5 cxd4 5.Bb5+ Bd7 6.Bxd7+ Qxd7 7.dxe6 Qxe6+ 8.Qe2!?

Fred Haley Wins Ryder Gambit

Fred Haley sent me a link to the following Live Chess game played on Chess.com. His higher rated opponent "nisapradila" was listed as being from Indonesia. Their contest was in the Blackmar-Diemer Gambit. Most players prefer to recapture with the knight after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 with 5.Nxf3. Dr. Ryder played 5.Qxf3 which offers a second gambit pawn on d4. E.J. Diemer played both moves.

The tricky part of the BDG Ryder Gambit is revealed most clearly when Black plays as below with 5…Qxd4 6.Be3 Qb4 attacking b2. White castles 7.0-0-0. The tempting blunder 7…Bg4? leaves Black in deep trouble as Fred Haley demonstrates.

Earlier in 2016 I wrote about the Real Dr. Ryder BDG story. BDG Ryder 6.Be3 Qb4 is section 1.4 in Blackmar-Diemer Games 1 and Blackmar-Diemer Theory 3.

Haley (1864) - nisapradila (2313), Chess.com, 06.12.2016 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Qxf3 Qxd4 6.Be3 Qb4 [6...Qg4!] 7.0-0-0 Bg4?
