[Mar 30, 2016] Updated Opening Line by GM Aleksandar Kovačević:
Queen’s Indian Defense, Nimzowitsch Variation with 5. Qc2

[Line 220 : 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Ba6 5. Qc2]

Line 220 deals with the very popular 5. Qc2, which often leads to sharp gambit lines. After 5… Bb7, White is practically forced to go for 6. Bg2 c5 7. d5. Very interesting positions occur, demanding precise knowledge of many nuances along the way. That being said, if White is not deeply prepared, he should by all means avoid 5. Qc2. Black also has a highly playable alternative in 5… Bb4+, which typically leads to somewhat passive, but ultimately very solid positions.

[Diagram: White to Move] Many White pieces are close to Black’s King, so everything is set for a decisive attack!

English Opening, Closed Sicilian Reversed – Kingside Fianchettos

[Line 008 : 1. c4 e5 2. Nc3 Nc6 3. g3 g6 4. Bg2 Bg7 5. d3]

Line 008 covers the main variation of the Closed Sicilian Reversed, where Black has ample opportunities to get satisfactory positions.

Our main line here is 5… d6 6. Rb1 a5 7. a3 Nf6 8. Nf3 O-O 9. O-O Re8, though there are other interesting variations as well, like 5… f5, followed by Nf6 and O-O, or a similar plan with 7… f5 8. Nf3 Nf6.

[Diagram: Black to Move] White’s position looks normal, yet after an unexpected move, Black gets some serious advantage.

Queen’s Gambit Declined, Harrwitz Attack

[Line 253 : 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 without 5. Bg5]

The Harrwitz Attack, characterized by the topical 5. Bf4 is, besides 5. Bg5, one of the two most popular systems against the Queen’s Gambit Declined. It’s a frequent guest among the elite so, due to sheer quantity of the information, the remainder of the material is covered in Lines 254-257.

The Fianchetto Variation with 5. g3 has recently gained in popularity, mostly due to Kramnik’s incredible input of original ideas for both sides, like in recent P. Svidler – V. Kramnik, Skopje 2015 and V. Kramnik – V. Topalov, Tromsø (ol) 2014.

We especially recommend that you take a closer look at an incredibly spectacular game P. Svidler – A. Morozevich, Sochi 2012.

[Diagram: White to Move] The diagrammed position is well-known from many games, ranging from classical B. Ivkov – K. Robatsch, Vinkovci 1968, to some recent correspondence and engine games. After energetic play, White gets a strong attack!

[Mar 27, 2016] New Opening Survey by GM Dragan Paunović:
A Good Day for the English Opening: Four Knights Variation, 13. Bf4!?

What made Caruana’s preparation for the Candidates 2016 Round 10 game against Anand so great was the fact that the former World Champion was practically forced to find a very difficult tactical counterplay over the board in a high-pressure situation. After he failed to do that, White emerged with a favorable middlegame, and after that everything went downhill for Anand.

This game is obviously highly important for the modern opening theory, but could also turn out to be the decisive one when it comes to determining the next challenger to the World Chess Crown.

[Diagram: Black to Move] Can you improve upon Anand’s play and find the path to equality for Black?

[Mar 26, 2016] Updated Opening Line by GM Boris Avrukh:
Gruenfeld Defense, Exchange Variation (Modern Main Line)

[Line 141 : 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Nf3]

As the main variation in Line 141 you will find the modern 7… c5 8. Be3 Qa5 9. Nd2!?, which was introduced at the elite level by GM Aronian in his games against Sutovsky and Grischuk. It is an interesting alternative to the heavily-researched lines that often leads to non-standard position. On the other hand, it is safe to say that 9. Bd2 hardly poses any problems to Black.

[Mar 25, 2016] Updated Opening Line by GM Aleksandar Kovačević:
Sicilian Defense, Classical Scheveningen – Maroczy Variation with 7. O-O Be7

[Line 486 : 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be2 e6 7. O-O Be7 8. f4 O-O 9. Kh1]

Line 486 covers the Classical Scheveningen, frequently employed with black pieces by Kasparov in his matches against Karpov in Moscow, 1985, and against Anand in New York, 1995. It remains a very popular opening at all levels, since it offers plenty of opportunities for both sides.

The main line of our choice in Line 486 is the Maroczy Variation, which occurs after 9… Qc7 10. a4 Nc6.

[Diagram: White to Move] A. Volokitin – S. Rublevsky, Budva 2004. All it takes for White is to strike while it’s hot, and the Black’s position will simply collapse.
