[Apr 01, 2016] Updated Opening Line by GM Slaviša Brenjo:
Four Knights Game, Spanish Variation – Rubinstein Variation (incl. Marshall Gambit)

[Line 375 : 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. Nc3 Nd4]

With the increased popularity of the Berlin Defense, many Anti-Berlin lines have become heavily explored, including the Four Knights Game.

The Rubinstein Variation, starting with 4… Nd4 leads to dynamic positions where Black often leaves the e5-pawn hanging and plays for the compensation. The most topical response for White is accepting the challenge, like in the main line with 5. Ba4 Bc5 6. Ne5 O-O, also known as the Marshall Gambit.

[Diagram: Black to Move] White is behind in development, which gives Black the possibility to gain serious advantage, with the help of a petite tactics!

[Mar 31, 2016] Updated Opening Line by GM Slaviša Brenjo:
King’s Indian Defense, Carlsbad Variation

[Line 128 : 1. d4 Nf6 2. c4 g6 3. Nf3 Bg7 4. g3 O-O 5. Bg2 d6 6. O-O Nc6]

Line 128 covers the Carlsbad Variation of the King’s Indian Defense, except for the positions that occur after 7. Nc3 a6, which is covered in our Line 129.

In the main line with 7. Nc3 Rb8 8. h3 a6 9. e4 b5 10. e5 most positions are very complicated, where Black usually gets enough counterplay, by countering White’s central advance with a flank attack.

Among the newly added games, there is a particularly interesting game L. Aronian – H. Nakamura, Zurich 2014, in the recently popular 10. d5 b4!?

[Diagram: Black to Move] A crazy tactical position, like the one on the diagram, demands accurate calculation. How should Black continue?

[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?
