Quinones - Eckhardt Blackmar-Diemer

The Blackmar-Diemer Gambit is well met by the solid Caro-Kann Defence type position with the Ziegler Variation 5.Nxf3 c6. This defence was recommended in a book by Boris Avrukh. Jorge Victor Quinones Borda gets his BDG tested in a game vs Andreas Eckhardt. Sometimes Jorge Quinones has played 6.Bc4 which has been the traditional move. However in recent years, players such as Jorge Quinones resort to 6.Bd3. Eckhardt chose 6...Bg4 when Jorge could have immediately kicked the bishop with 7.h3. On the other hand, after 7.Be3 e6 8.h3 Bxf3 (instead of 8...Bh5) 9.Qxf3 transposes directly into a well-known BDG Teichmann Variation.

Quinones - Leisebein Bogoljubow 6.Bf4

Last Saturday we looked at a Blackmar-Diemer Gambit game played by E.J. Diemer vs Manfred Kloss in the Bogoljubow 6.Bf4 variation. In that game after 8.0-0-0 c5 9.d5 a6, Diemer played 10.h3 and the winner Kloss discussed the possibility of 10.d6 in the notes. Today we look at Jorge Victor Quinones Borda vs BDG specialist Peter Leisebein. In that game the move 10.Be2 played by Quinones has several advantages.

(1.) 10.Be2 develops White's last minor piece. (2.) 10.Be2 avoids creating easy targets like the moves Bc4 or Bd3 could do. (3.) 10.Be2 might support a future pawn push h4-h5. (4.) The bishop defends Nf3. (5.) If the Nf3 moves or is removed, the bishop can be useful on the Bf3-a8 diagonal. (6.) 10.Be2 is favored by chess engines like Houdini.

Francesco Cavicchi Lemberger 4.Nge2

Blackmar-Diemer Gambit friend Francesco Cavicchi made interesting comments about the dreaded Lemberger Counter Gambit - 1.d4 d5 2.e4 dxe4 3.Nc3 e5!? The issue is significant to BDGers so I plan three posts to examine it based on our chats last week. Francesco raised some good points. Today I consider the Lemberger 4.Nge2! which is known as the Rasmussen Variation. Next Thursday I consider his comments about other variations, and a third Thursday we will examine 4.Qe2!? in detail.

Francesco Cavicchi: "The Lemberger, what a nightmare. I stopped playing BDG because of that infamous 3...e5...  In the Rasmussen nge2 black has so many possible answers at disposal."

Tim Sawyer: "As you will see when I next write about this, the correct idea after 4.Nge2 exd4 is 5.Qxd4! I expect to cover this again in about a week."

I agree with Francesco. Black has "many possible answers", but only a few are good. Not only that, very often players follow 4.Nge2 exd4 5.Qxd4 Qxd4 6.Nxd4 Nf6 7.Bg5. White has quick development. Black has weak points on e4, f6, and c7. Usually White regains his gambit pawn very quickly. With that, all the center pawns have disappeared and the position is wide open. Below I play Rybka in what is for me a rare 3...e5!? Usually I play to hold the gambit pawn with 3...Nf6! Chances are equal, but in the case of my blitz game below, the skill levels varied widely. White just had to play chess. My 7...Nbd7 was a quick natural developing move but a bad blitz blunder.

Rybka (2719) - Sawyer (1935), Florida blitz 12.02.2011 begins 1.d4 d5 2.e4 dxe4 3.Nc3 e5 4.Nge2 exd4 5.Qxd4 Qxd4 6.Nxd4 Nf6 [This knight move is by far the most common. Two options show White is also at least equal. 6...Bb4 7.Ndb5 Bxc3+ 8.Nxc3 Nf6 9.Bg5 Be6 10.Bxf6 gxf6 11.Nxe4 Nd7 12.0-0-0 0-0-0 13.f4=; 6...Be7 7.Bf4 Nf6 8.Ndb5 Na6 9.Bxc7 Nb4 10.0-0-0 Bg4 11.Re1 a6 12.Nd4 0-0 13.f3=] 7.Bg5 Nbd7?!

Quinones vs Schutzbach Blackmar-Diemer

On Tuesdays I plan to look at Blackmar-Diemer Gambit Accepted games. Today we have one from Jorge Victor Quinones Borda vs Gerd Schuetzbach.

"Good morning Mr. Sawyer,
Maybe you would like some of the games.
The game against Gerd uses an idea by David Flude that appeared in the Scheerer´s book... Jorge Quiñones Borda"

The Blackmar-Diemer Gambit Euwe is a very popular variation which is sometimes recommended by theoreticians. In practice White tends to score very well. In theory after 5.Nxf3 e6 6.Bg5 Be7, the line 7.Bd3 Nc6 can be somewhat challenging, although in practice White often wins. Author Christoph Scheerer notes that David Flude has the idea to hold off playing Bd3 and first develop and castle queenside with 7.Qd2 0-0 8.0-0-0. Jorge tests it out by playing a line that looks promising. The last half of the game proved to be difficult to win.

Quiñones - Schuetzbach, frei www.remoteschach.de, 31.05.2013 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 e6 6.Bg5 Be7 7.Qd2 0-0 8.0-0-0 c5 9.Qf4!?

Ruy Lopez Fishing Pole Bait and Switch

This week "Chess Bull" emailed to me three 3-minute Ruy Lopez blitz games where Black won using the Fishing Pole variation. Brian Wall made it his pet line. My first post on the Fishing Pole ranks 5th in my all-time Top 30 list, now with over 500 page views.

Part of Chess Bull's email got cut off on my end, but basically he wrote:
"fishing pole: these are my 3min blitz games. i need ur help to improve my chess career. what are my mistakes in that games tell me please... in last game (if in 21.q*g3 ne2+)"

The Fishing Pole begins 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 Ng4. The knight is the bait. If White plays the natural 5.h3, then Black reaches out the pole with 5...h5. The hook is the support the h5 pawn provides his piece on g4. If White immediately grabs the bait with 6.hxg4, Black chomps back with 6...hxg4, attacking the Nf3. If that White knight moves, then Black can play 7...Qh4 threatening checkmate.

Three minute games tend to just be fun and exciting for their own sake, but we can learn lessons from specific moves or ideas. The first two were more common in terms of Fishing Pole theory. In each after 4.0-0 Ng4, White made d-pawn pushes:
(A). 5.d4 exd4 6.Nxd4 and now I suggest 6...Nxd4 (After6...Bc5 7.Nf5! White had a big advantage.) 7.Qxd4 c6 8.Be2 Qf6 with only a temporary White space advantage.
(B). 5.d3 Bc5 6.c3 a6 7.Ba4 b5 8.Bc2 and now I suggest 8...d6 seems like a better idea than 8...h5 which Chess Bull played in that game.

We can learn the most from the last game. White avoids 4.0-0 Ng4 with 4.Qe2. After 4...Bc5 5.c3, the Fishing Pole idea with 5...Ng4 is far more risky than Black needs to be. However fishing is fun! The knight on g4 become the bait. White nibbles with 9.h3 but does not bite. Eventually it gets to dangerous for the stead to stay and it retreats with 12...Nf6. Because Black knows the Fishing Pole idea, he can switch bait and toss the bishop out there with 14...Bg4. White takes the bait and it hooked.

Lesson: Black's combination of dark squared bishop, active kingside knight, open h-file for the rook, advanced g-pawn and powerful queen, force an impressive checkmate threat. In the end, there was no defence to this Chess Bull Fishing Pole Attack.

NN - Chess Bull, Fishing Poles Games, 2014 begins 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.Qe2 Bc5 5.c3 Ng4?! [Better is 5...0-0 6.0-0 when Black has three playable lines: 6...d6, 6...Re8 or 6...Qe7] 6.0-0 d6 7.d3 [7.d4!+-] 7...a6 8.Bxc6+ bxc6 9.h3 h5 10.Nbd2 Qe7 11.Nc4 Be6 12.Ne3 Nf6 13.Bd2 Qd7 14.Ng5 Bg4 15.hxg4 hxg4 16.f3 [Again 16.d4+- ] 16...g3 17.Qe1 Nh5 18.b4 Ba7 19.Qe2?
