BDG Tom Cat Plans that Backfire

In the 1960s there was a series of cartoons featuring Tom Cat, also known as Tomcat, Thomas, and Tom of "Tom & Jerry" fame. Wikipedia notes of Tom: "He is continuously after Jerry Mouse, for whom he sets traps, many of which backfire and cause damage to him rather than Jerry."

There are times in chess games were we set traps that backfire. Today we see the game Tamkat vs Bill Wall. White plays the Blackmar-Diemer Gambit Accepted but Tamkat chooses the rare 5.gxf3?! It does have the advantage of fighting for the e4/g4 squares, but the pawn on f3 interferes with White's own development.

Tamkat-Wall, Internet .10), 1996 begins 1.d4 d5 2.Nc3 Nf6 3.e4 dxe4 4.f3 exf3 5.gxf3 Bf5 6.Bf4 e6 7.Bc4 Bb4 [7...Bd6!-/+] 8.Nge2 Nd5 9.Be5? [9.Bxd5 exd5 10.Qd2 0-0 11.0-0-0 Nc6=/+] 9...Ne3 10.Qd2 Nxc4 Black has the advantage off the two bishops. One of them is an extra bishop! 0-1

Blackmar-Diemer Dark Knight Falls

When you are bold enough to play the Blackmar-Diemer Gambit, your courage is often rewarded by blunders made in positions where Black does not see the coming danger. One such mistake can cost Black a Knight immediately. Probably this would not happen in the theater of a slow tournament game vs a strong player. However players up through the 1700s have made this blunder vs me in blitz and offhand games.

Here is the setting: White plays 1.d4 and Black answers in kind with 1...d5. The enterprising BDG player grabs the e-pawn and tosses it to 2.e4!? challenging d5.
Now Black has a critical decision to make: Capture, Defend or Attack.

2...dxe4 - Heading toward a Blackmar-Diemer Gambit 3.Nc3 Nf6 4.f3.
2...e6 - French Defence. BDGers enjoy a lot of French experiences.
2...c6 - Caro-Kann Defence. BDGers very often face the Caro-Kann.
2...Nc6 - Queens Knight Defence, Nimzowitsch Variation. I play Black.
2...c5 - Reversed Albin Counter Gambit giving White an extra tempo!
2...e5 - Attacking Center Game style when White again has the move.
2...Nf6 - The BDG Avoided line is worth a shot and covered below.

50 times I reached 1.d4 d5 2.e4 Nf6. 49 times I pushed 3.e5 and scored 96%. 26 times I have been gifted the Dark Knight with 3...Ne4? and scored 100% after 4.f3. My average opponent in these 26 games was rated 1402. My opponent below was rated 1723.

Recently I decided to play some 3 minute blitz games on Chess.com. I am fairly new to play there. They started me down in the 1300s or so. After a few games I was in the 1700s. Then I left Chess.com returning to the Internet Chess Club where I play regularly and used to be rated in the 2400s. Last week I decided to go back to Chess.com. My rating drifted up to the 1900s (1906 for the game below). Last I looked I was rated 1934.

Sawyer-guillermocardet, Live Chess Chess.com, 30.07.2012 begins 1.d4 d5 2.e4 Nf6 3.e5 Ne4? [3...Nfd7 4.e6!? fxe6 5.Bd3 e5? The logical attempt to undouble the e-pawns fails to mate in 3 with 6.Qh5+ g6 7.Qxg6+ hxg6 8.Bxg6 mate!] 4.f3 Ng5 5.Bxg5 1-0

Find Forks Forgets f7 Failure

Shortly after players learn basic strategy and a few tactics, most are tempted to fall in love with the Knight Fork on c7/c2, f7/f2 and wherever else they show up. Below Bill Wall provides us with an internet example of what happens in a Blackmar-Diemer Gambit Pietrowsky when a player keeps trying to find forks but forgets to develop and defend his own king. When Black finally succeeds in taking a bishop and forking a rook and queen, White plays mate in 2.

Mr. Wall has been so very generous as to give me over 100 of his own games when he played the BDG. Thank you, Bill! Wall's games are scheduled Monday-Friday at 6 PM. For those that are new to this site, I generally post 6 AM and 6 PM Eastern.

I collect and annotate BDG games, and other openings, as my blog readers know. Sometimes I add a short story. If you would like for me to use your games in this blog, please e-mail them to me at sawyerte@yahoo.com.

Wall-Merk1, Internet .09), 1996 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Nc6 6.Be3 [6.Bb5 is considered the best move.] 6...Bf5 7.Bc4 Nb4 8.Rc1 [8.Bb3 is an alternative.] 8...h6?!

104 Queens Gambit Accepted 7.a4 etc

Welcome to Main Line Monday. This is part 4 of 6 sections giving a complete repertoire for Black with the Queen's Gambit Accepted. Today we look at various 7th move options after 1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.e3 e6 5.Bxc4 c5 6.0-0 a6.

Of the selections below 7.a4 will be considered the primary move. A common theme in these lines is White's Isolated Queen Pawn on d4 vs Black's pawn on e6. The key square is d5. The pieces on both sides have active open lines.

Two other moves not covered this week that will be given on the next two Mondays. One is the popular 7.Qe2 and the other is the trendy 7.dxc5.

Penullar Quick Winckelmann-Reimer

The French Defence is a good opening that has survived the test of time. Recently there seems to be a surge in popularity. Many new books and DVDs have hit the market done by famous titled players. White seems to be able to play anything vs the French, but nothing wins by force. Black always finds a playable line.

Peter Mcgerald Penullar played the French Defence Winawer 4.a3 gambit line. With 6.f3 Penullar went into the Winckelmann-Reimer Gambit, which has the look and feel of the Blackmar-Diemer Gambit. The WRG has been the subject of some debate over the years.

Sometimes it is faster to win with a Winckelmann-Reimer Gambit than say the name. There are lines completely losing for Black while other lines might favor Black. One thing is known: taking the gambit pawn immediately with 6.f3 exf3 is bad for Black. I have over 400 games in my collection where Black has captured with 6...exf3. White has won 88%! White still has to play well. Below is an example where Penullar does just that. Nice win!

penullar-jaruta, Live Chess Chess.com, 24.07.2012 begins 1.d4 d5 2.e4 e6 3.Nc3 Bb4 4.a3 Bxc3+ 5.bxc3 dxe4 6.f3 exf3 [The most popular move is 6...c5 when White has tried 15 different moves. I do not know which one is the best. Of those that have been played at least 50 times, the two that score the best are 7.Rb1 and 7.Bf4] 7.Nxf3 Nf6 8.Bd3 h6 9.0-0 b6 10.Be3 [A new move. White has done well with 10.Qe1!+/- a few times before.] 10...Bb7 11.Qe1 0-0 12.Qh4! [Or 12.Qg3!?

Muchamedschanow vs Caro-Kann

For the first 35+ years of my life, the United States and USSR (Union of Soviet Socialist Republics) were involved in a Cold War: Capitalism vs Communism. Most Americans just wanted to live their life in peace. I suspect that was the wish of most Russians too. From the American standpoint, we believed that socialism robbed people of freedom. Back in the 1970s we would not elect an openly socialist president of the United States who hoped to change the government to exercise strong control over people's lives.

My first opponent from the USSR was W. Ch. Muchamedschanow. We did not chat much on our postcards; we just sent moves. I imagine we were on some watch list since numerical chess notation could look to the suspicious like secret codes. This was six years after Fischer-Spassky 1972. I did not find anybody by my opponent's name in the rating list. ICCF does have a Flur Sabitovich Mukhamechanov (rated 2157 - same as me).

The opening I studied most in 1978 was the Classical Caro-Kann Defence. I looked at many games in this line. The line was too dull for me. I only beat weaker players. Usually I fell asleep mentally and missed opportunities when they arrived. Muchamedschanow played the sharp 11.Rh4 variation against which my performance has been about 100 rating points below my actual rating. Here I make a blunder on move 23 and lose. We did not have databases back then, but now I see the 1976 game Bellon-Pomar had the same blunder, although GM Pomar played on for a while before giving up.

Muchamedschanow-Sawyer, corr ICCF 1978 begins 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Bf5 5.Ng3 Bg6 6.h4 h6 7.Nf3 Nd7 8.h5 Bh7 9.Bd3 Bxd3 10.Qxd3 Qc7 [The Black queen takes control of the h2-b8 diagonal. 10...e6 is more popular nowadays.] 11.Rh4 [This is a tricky line that I have faced several times but not handled well. This as my first experience with it. The famous Geller lines goes 11.Bd2 e6 12.0-0-0 Ngf6 13.Ne4 0-0-0 14.g3=] 11...e6 12.Bf4 Bd6 [12...Qa5+!?] 13.Bxd6 Qxd6 14.Ne4 Qe7 15.Qa3 Qxa3 16.bxa3 Ke7 17.Rb1 Rb8 18.Nc5 Nxc5 19.dxc5 a5 [Maybe better is 19...Nf6 20.Rhb4 b5 21.Ne5 Rhc8] 20.Ne5 Nf6 21.Rd4 Rhc8 22.g4 Rc7 23.f3 Rd8 [23...Nd7 24.Nd3+/-] 24.Rxb7! 1-0

Alain Couture vs Jocelyn Bond Reti

Jocelyn Bond returns with a game from Canada in the Reti Opening:

"Hi Tim, I come back to present you a game I played this week from the Jonquiere chess championship that I'm actually playing each Wednesday. This Wednesday evening, I faced to Alain Couture, an excellent chess player. He's difficult to beat him. Remember 30 minutes to mate per game.

"In our first game, I won easily after 1.d4 c5 2.d5 e5 3.Nc3 etc. but in the second game, as black, I won with much difficulties. With 1 minute less each one, he blundered a minor piece (34.Be5??) and after that I was lucky to win. These result gives to me 10 points in 10 games. Sorry no BDG this week. Now, 4 games left for me on next 2 weeks."

Alain Couture (1800) - Jocelyn Bond (1957), Jonquiere ch (10), 25.07.2012 begins 1.Nf3 Nf6 2.b3 d5 3.Bb2 c6 4.Ne5 Bf5 5.f4 (humm, a Bird) 5...e6 6.e3 Nbd7 7.Be2 Ne4 [7...Nxe5 8.fxe5 Ne4 9.0-0=/+] 8.0-0 [8.Nf3=] 8...f6 [8...Nxe5!? 9.fxe5 Bc5=/+] 9.Nf3 [9.Bh5+ g6 10.Nxd7 Qxd7+/=] 9...Qb6!?

The game was over after a mate on f1 by the black queen helped by a rook on the f file. [Notes by Bond and Deep Fritz] 0-1
