A20: English

The starting point of this investigation by GM Zoltan Ribli occurs after the moves 1.c4 e5 2.g3 Nf6 3.Bg2 d5 4.cxd5 Nxd5 5.Nf3 Nc6 6.0-0 Nb6 7.d3 Be7 8.Nbd2 0-0 9.a3 a5 10.b3 Be6 11.Bb2 f6 12.Qc2 Qd7



In this position, which is actually a reversed Sicilian Defense, White has two main continuations: 13.e3 and 13.Rfd1. “Of course, other moves are possible,” Ribli writes, “for example 13.Rac1, but this move is of no independent significance. There is quite an important difference between this position and the Sicilian Defence. Here White is employing a Sicilian setup with an extra tempo, so that Black does not find it so easy to (or cannot) attack on the kingside with f5 –so he must play in the center. On the other hand White has a very sound position with two bishops on the long diagonals and possibly (after due preparation) he can manage to get in the move d3-d4.”

GM Ribli ends his article with the following conclusion: “This variation, 8.Nbd2, has accumulated less theory than the main line 8.Nc3. The setup with g3-Bg2 and b3-Bb2 is somewhat reminiscent of hedgehog positions, in which the opponent also controls more space. But Black must be careful – if White can manage to play d3-d4, then it is possible, that with his two bishops on the long diagonals he is better placed. However, in general chances are about level.”

B75: Dragon Sicilian

“In the spring of 2005,” writes GM Dorian Rogozenko, “I was playing in an open tournament in Galati, Romania. There I witnessed a game, which started with the Pirc move order 1.e4 g6 2.d4 Bg7 3.Nc3 d6 4.Be3 Nd7 5.Qd2 c5. White continued 6.Nf3 cxd4 7.Nxd4 Ngf6 8.f3 and the game suddenly transposed into a strange Dragon Sicilian, where Black had developed the knight on d7 instead of the usual square c6:



Looking at the board at that moment, I was trying to recall if I had ever seen anything like this in the Dragon. I could vaguely recall Kasparov,G-Georgiev,K, 1-0, in Sarajevo 2000, and a bit more clearly Botvinnik’s conclusion from his own book. Since I had never considered such a set-up in the Dragon to be serious, I felt happy for the player with the White pieces. However, in Ionica,I-Bogdan,D, 0-1, Galati 2005, White castled long and then advanced her kingside pawns (apparently a totally logical step in the Dragon). However, the battle lasted for less than 25 moves – White was completely crushed. In the post-mortem analysis several IMs failed to figure out where White went wrong and what was the cause of such a quick defeat...

In the present survey we will analyse this unusual Dragon and see what the best plans are for White and for Black. But before looking at ideas and concrete variations, I’ll say a few brief words about the history of the variation being examined. It occurred for the first time in 1945 in a game of Alexander Alekhine. However, the 4th World Champion soon implemented the plan with ...Nc6 and ...Bd7, which has nothing to do with the specifics of this line. In the beginning of the 1960s Mikhail Botvinnik used Black’s set-up in two games. Botvinnik himself considered that the entire idea of Black’s queenside development belongs to Reshevsky, who played so in 1957. After Botvinnik’s games, the present system wasn’t used by strong players for many decades and therefore theoretical sources don’t really analyse it. In fact, there is practically no theory at all.

In 2004 several British players, including the Dragon expert Ch. Ward, implemented the plan with ...a6 and ...Nbd7. But the revival happened at the end of 2005 during the World Cup in Khanty-Mansiysk, when first Khalifman and then Sakaev won two very important games with Black. After Khanty-Mansiysk, GMs J. Ehlvest, A. Fedorov and S. Kudrin started to play this system as well, the last two of them being well-known Dragon experts.”

The variation that GM Rogozenko looks at, starts with the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 a6



Rogozenko: “Unlike in the traditional Dragon, here Black plans to continue with b7-b5, develop the bishop to b7 and the queen’s knight to d7. Then the second player should act according to circumstances. Usually the rook goes to c8, building up activity along the c-file (including ideas of an exchange sacrifice on c3). Generally Black’s play in this system is quite easy, since his next 3-4 moves are often the same, no matter what White’s plan may be.

The first player has a larger variety of ideas. The standard plan in the Dragon with Qd2, 0-0-0 and an eventual exchange of dark-squared bishops on h6 is strong here as well, even if there are some specific subtleties for this concrete variation. The main difference is that here Black delays castling short and thus White cannot develop a quick attack on the kingside. Another thing is that the inclusion of the moves h4/h5 almost always favours Black.

Besides castling long, White also has ideas about play on the queenside thanks to the fact that the black pawn on b5 offers White active possibilities connected with a2-a4. In that case White will castle short and simply enjoy a strategic advantage due to Black’s weak pawn structure. Notice that this plan is usually effective with the white light-squared bishop on the diagonal f1-a6. With White’s bishop on b3 the advance a2-a4 is less dangerous for Black. Needless to say, after White has castled long, the move a2-a4 loses its attractiveness. Also with the king on e1 the advance a2-a4 can have its drawbacks when White already made pawn advances on the kingside (such as g2-g4 and/or h2-h4), after which he might have problems finding a safe place for his king. However, this is a very general thought and sometimes White can wisely combine g2-g4 with a2-a4 and then castle short.

Further, we come to another important thing for the understanding of the present system: is the development Bf1-c4-b3 good for White, or is it better to keep the bishop on the diagonal a6-f1? I think that psychologically many players refrain from considering the move Bf1-c4 simply because it offers Black a tempo for the advance ...b5. Indeed, in practice the majority of strong players prefer not to spend time on Bf1-c4. Nevertheless the plan with Bf1-c4-b3 is strong. There are important factors speaking in favour of having the bishop on b3. First of all, in the Dragon the b3-square is traditionally a good attacking and defending square for the bishop. Secondly, here the control over the square d5 is especially important because Black can always increase his control in the centre by playing ...b4 and chasing the knight from c3. Usually after ...b5-b4 it is desirable for White to jump with the knight to d5. In that case it is important to have the knight supported by the bishop from b3. Finally, White’s most active plan is to play Qd2 and Bh6. A standard reaction from Black to such a plan is to take on h6 and then build his counterplay on the idea of sacrificing the exchange on c3, using the fact that White’s queen went to h6. In those structures the most important piece, which protects White’s broken queenside, becomes the bishop on b3 (neutralizing for instance the dangerous manoeuvre Nd7-b6-a4).”

Rogozenko proceeds to look at concrete variations, and at the end of his extensive analyses comes to the following general conclusion: “Most positions which arise from the set-up with ...a6 and ...b5 offer a lot of possibilities for both sides. While Black’s moves at the beginning are standard (...Nbd7, ...b5, ...Bb7), White has several plans to choose from, the strongest being connected with Bf1-c4 followed by Be3-h6. In that case Black can try the aggressive and basically unexplored 12...b4, trying to change the character of the position. The main merit of the system we have examined is that both sides must enter relatively new territory. By choosing this line with Black, one has the rare chance to enjoy playing the Dragon without learning endless theoretical variations.”

C10: French Defence 3…dxe4

The subject of this article starts after the moves 1.e4 e6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Nf3 Ngf6 6.Nxf6+ Nxf6 7.c3



GM Alexander Finkel writes: “As I mentioned in my previous survey, the relatively modest move 7.c3!? has become one of the most popular ways to meet the Rubinstein variation during the last couple of years. Despite a general impression that Black should be doing fine after 7...c5 which was covered extensively in issue 111 of ChessBase Magazine, many players prefer not to commit with an early advance of the c-pawn, opting for 7...Be7, 7...a6!?, 7...Bd6 or even 7...h6?!.

One of the greatest specialists in the French Defence in the world, Evgeny Bareev, has opted for 7...Be7 on a couple of occasions, so it most definitely means that this line is playable for Black (other moves are rather rare, so we will just refer to them very briefly)! I would say that this move is more flexible than 7...c5, but it is probably White who enjoys its flexibility more as he can test Black’s defensive set up with a variety of different plans!

The way I see it, once Black has played 7...Be7 there is no point in pushing ...c5 as quickly as possible (I mean he could have played it on the previous move if he had wanted to), so he should just finish the development of the pieces by 0-0, b6 and Bb7. In the meantime White may build up a menacing attacking line-up with Bd3, Qe2, Bg5 and 0-0-0, planning to break through on the kingside. Basically Black’s counterplay on the queenside is considerably slower, but in most cases he may use the open d-file in order to initiate a trade of the major pieces and reduce White’s attacking potential.

It seems that White should be slightly better both after the sharp 0-0-0 and the less aggressive 0-0, but I believe Black has sufficient counter-chances in both cases.”

The author’s conclusion after extensive analysis: “In spite of a number of promising options, I failed to find a line with a steady opening advantage. It seems that Black is relatively safe after 7...Be7, so the overwhelming popularity of 7...c5 is no more than a fashion. As for the concrete lines which I consider the most promising, I would point out 8.Bd3 c5 9.Ne5 as an interesting try to pose Black problems. Another line which looks rather appealing to me is a plan with 8.Be3 and queenside castling. The plans with kingside castling by White are not very dangerous for Black, but if I had to recommend one I would most definitely go for Bf4.”

Content of the attached database: 1) 64 games played in this line. Most of the games have been played during the last couple of years. On the white side you will find such strong players as Shirov, Adams, Grischuk, Volokitin, Motylev and many others who have used this variation occasionally. As usual, on the black side you will find quite a few experts in the French Defence: Bareev, Morozevich, Short, Baklan, Noguieras. 2) 21 annotated games (15 of them exclusively for this database). 3) A very deep opening key designed especially for the database to make the learning process more efficient.

C40: Elephant Gambit

In the previous issue of ChessBase Magazine the starting point of Peter Leisebein’s comments was the position after the moves 1.e4 e5 2.Nf3 d5 3.exd5 e4:



Black presses forward at once with his e-pawn and burns his bridges behind him! 4.Qe2! Nf6. White can get rid of the kamikaze pawn at once with 5.Nc3, but this runs into tactical problems. White achieves no advantage by doing so!

According to theory, after 1.e4 e5 2.Nf3 d5 3.exd5 e4 4.Qe2 Nf6 5.d3!



The last move is almost to be seen as a refutation. But if you look at the statistics for games played during the last 12 years, you get quite a different impression! An exciting position has arisen. Black is threatening to castle quickly and to install a rook on the e-file. White on the other hand cannot bring his king to safety so quickly since the queen is blocking the bishop. On the other hand, there is the threat of dxe4 and White is two pawns up.

Black has three possible ways of developing his bishop in order to speed up the development of his kingside:
Develop it on e7. The disadvantage of this natural developing move is that Black now blocks his own e-file.
Develop it on c5. This possibility looks better, since the bishop is more active and the e-file is not blocked. In the game Buchmann,H - Leisebein,P I soon managed quite a spectacular liquidation to a draw.
Develop it on b4. This move is aimed at castling without wasting any time, according to F. Gutmayer’s “snappy tempo”. Tactically speaking, it is fully justified, but the procedure has positional shadow sides!

So the development of Black’s bishop appears to give an advantage to White, but there is probably a very good way to get a level game. I have been experimenting quite successfully with the move 5...Qxd5!?. In Konikowski and Gupta’s book, this move is described as doubtful. But I consider it to be the best reply for Black!

This is the last of a series of eight articles by the author on the Elephant Gambit that appeared in ChessBase Magazine. “I hope that I have managed to provide some stimulation for adventurous players who are not afraid of taking some risks,” Leisebein writes. “Some final evaluations cannot yet be made. In 1994 Konikowski and Gupta published their book and database about the Elephant Gambit. The least one can say is that a lot has happened in this opening over the last 12 years! I can but heartily recommend this opening to all those players who love fighting chess.”
