Queen’s Gambit Declined – Exchange Variation; Catalan Opening

[Line 265 : 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 c6 without 5. Bg5, 5. e3]

Two main moves from the initial position of our Line 265 are 5. e3 (Lines 274-285) and 5. Bg5 (Lines 266-273), and we deal here with other various possibilities.

Exchange Variation (5. cxd5) is probably the most suitable for beginners. After the usual 5… exd5 6. Bg5 White’s plan often includes Qc2, e2-e3, Bd3 and O-O.

Move 5. g3 leads to the gambit variation of the Catalan Opening and is more suitable for advanced players. The principal reaction is 5… dxc4 and after 6. Bg2 one option is 6… Nbd7 7. O-O with either 7… b5 or 7… Be7, and the other option is 6… b5 7. Ne5 Nd5, in any case with roughly equal positions.

From other choices of White defending the c4-pawn with either 5. Qd3 or 5. Qb3 typically leads to quiet positions.

[March 29, 2017] Updated Opening Line from Dragan Paunović:
English Opening, Nimzowitsch Variation

[Line 005 : 1. c4 e5 without 2. Nc3]

This update is a small tribute to our late colleague GM Dragan Paunović. In memory of our dear friend, our Editorial Board will continue updating his lines and articles.

There are a couple of popular alternatives to 2. Nc3 (Lines 006-017), which is the main option in the English Opening.

Early kingside fianchetto 2. g3 occurs quite often even on the highest level. After 2… Nc6 a game often transposes to the lines stemming from 2. Nc3; for example position arising after 2… Nc6 3. Bg2 Nf6 4. Nc3 is covered in our Line 011. For club level players we recommend 2… c6, where after the most common 3. d4 Black is able to equalize with 3… e4 4. Nc3 d5. The most frequently seen follow-up is 2… Nf6 3. Bg2, where some of the ways for Black to gain satisfactory positions are 3… c6 4. d4 Bb4+, 3… d5 4. cxd5 Nxd5 5. Nf3 Nc6 6. O-O Nb6 (preventing White from playing d2-d4) and 3… h6!? 4. Nc3 Bb4.

In the Nimzowitsch Variation (2. Nf3) Black is fine both after 2… Nc6 3. d4 exd4 4. Nxd4 Bb4+, and 2… e4 3. Nd4 Nc6.

[Diagram: White to Move] L. Portisch – Lj. Ljubojević, La Valetta (ol) 1980. Portisch obtained a small advantage with 9. cxd5 Bxd5 10. Bxd5 Nd4 11. Bg2 Qxb5 12. Qxb5 Rxb5 13. Rb1. However, there is an even stronger continuation for White in the diagrammed position – can you find it?

NEW UPDATED OPENING LINE

[March 28, 2017] Updated Opening Line by Bojan Vučković:
Gruenfeld Defense, Exchange Variation (Classical Main Line)

[Line 144 : 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4]

After the introductory moves of our Line 144, the game usually continues with 7… c5 8. Ne2 Nc6 9. Be3. Now, Black has at his disposal a sideline 9… cxd4 10. cxd4 b5!? that should give him a satisfying position. By far the main option is 9… O-O, where after 10. O-O Black has several viable choices. Line 145 is dedicated to 10… Bg4 and 10… Qc7, while 10… Na5, 10… Bd7 and 10… b6 are also frequently seen in top level games.

The position arising after 10… Na5 11. Bd3 b6 is highly complicated and well-investigated, so it demands a considerable knowledge of many nuances.

Variations 10… Bd7 11. Rb1 Qc7 and 10… b6 are a bit less forced, though equally complex.

Sicilian Defense, Najdorf Variation – Amsterdam Variation

[Line 479 : 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. f4]

The Amsterdam Variation has lost a lot in popularity in the recent years, since Black has found a couple of ways to get good prospects.

Move 6… e5 is considered to be the main line. After 7. Nf3 Nbd7 8. a4 Be7 players of White generally choose between 9. Bd3 and 9. Bc4.

Another reputable option for Black is 6… Qc7, and is often connected with a kingside fianchetto. For example 7. Bd3 g6 8. O-O Bg7 9. Nf3 Nbd7, and the position is about equal.

Black can also start immediately with 6… g6, with the idea to respond to 7. Nf3 with 7… Nc6.

There is also nothing wrong with 6… Nbd7, followed by either g7-g6 and Bg7, or e7-e5.

[Diagram: White to Move] White has better piece development, while black dark-squared Bishop is unprotected. This gives White tactical motifs leading to strong initiative!

October 2014 Revisited: Neo-Gruenfeld Defense, 17. Ka1!?

This update is a small tribute to our late colleague GM Dragan Paunović. In memory of our dear friend, our Editorial Board will keep updating his lines and articles.

This reasonably popular line has a steady influx of important games, so it was high time to update it with new developments. While D. Naroditsky – V. Fedoseev, Doha 2015 appears to be the best play for both sides, there are many more theoretically relevant games. Our diagrammed position comes from another key game – T. Sanikidze – D. Wagner, Drancy 2016, where we offer an improvement on Black’s original play from the stem game.

[Diagram: Black to Move] Black pieces seem rather uncoordinated, and White’s d6-pawn is a big asset. How can Black create sufficient counterplay that leads to roughly equal positions, before it becomes too late?

NEW UPDATED OPENING LINE

[March 25, 2017] Updated Opening Line by Bojan Vučković:
Queen’s Indian Defense, Kasparov-Petrosian Variation (incl. Murey Variation)

[Line 212 : 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. a3 Bb7 5. Nc3 d5 6. cxd5 Nxd5 7. Qc2]

Move 7… c5 transposes to Line 208, while after 7… Be7 White has, apart from 8. e4 Nxc3 9. bxc3, another popular possibility in 8. Bd2 (Line 210).

The most frequently played option is 7… Nxc3, where 8. Qxc3 is a line more suitable for club level players.

White gets a strong pawn center in the Murey Variation (8. bxc3), where Black’s usual plan is to exert pressure along d- and c-files with c7-c5, Qc7(8), Nd7(c6) and Rd8. An illustrative continuation could be 8… Be7 9. e4 O-O 10. Bd3 c5 11. O-O Qc7 12. Qe2. Here both 12… Nd7 and 12… Nc6 lead to positions with roughly equal chances.

[Diagram: White to Move] It looks like Black has just enough counterplay on the queenside. However, White can still obtain a big edge and launch a strong attack on the poorly-protected black King. Any thoughts?
