NEW UPDATED OPENING LINE

[Jun 03, 2016] Updated Opening Line from GM Bojan Vučković:
Sicilian Defense, Modern Variation – Moscow Variation with 3… Nc6 (Main Line)

[Line 460 : 1. e4 c5 2. Nf3 d6 3. Bb5+ Nc6 4. O-O Bd7 5. Re1 Nf6 6. c3]

Since moves 6… g6 and 6… e6 in our opinion lead to White’s advantage, the only ambitious line for Black is 6… a6, where White has two principal continuations: 7. Ba4 and 7. Bf1. If we follow the first option, after 7… b5 8. Bc2 Bg4 we recommend either 9. d3 or 9. h3 for club level players, and 9. a4 for the advanced ones.

After 7. Bf1 Bg4, White again has an interesting choice between the solid 8. h3 and 8. d3, or mostly sharp 8. d4.

Although Black can equalize, highly accurate play is mandatory in most of the abovementioned lines!

NEW UPDATED OPENING LINE

[Jun 02, 2016] Updated Opening Line from GM Borki Predojević:
Slav Defense, Schallopp Defense

[Line 094 : 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. e3 Bf5]

For beginners, our recommendation is quite simple: 5. Bd3 Bxd3 6. Qxd3, followed by O-O, Nbd2, b3 and Bb2 – that plan can hardly go wrong!

The main focus of Line 094 is the 5. Nc3 variation of the Schallopp Defense, since all other White’s moves at that juncture are rather unambitious.

5… a6 is an interesting possibility for Black, especially for club level players. It should give the players of Black good prospects, and there is not as much theory as in the main 5… e6 line.

Variation 5… e6 6. Nh4 is covered in our Lines 095-097, and the remaining options for White on 6th move are covered here.

6. Bd3 Bxd3 7. Qxd3 hardly poses any problems to Black, since it simplifies the position, which is clearly in his favor.

[Diagram: Black to Move] This is an opening trick that could be seen even in a few grandmaster games: Black to play and get a substantial advantage!

NEW UPDATED OPENING LINE

[Jun 01, 2016] Updated Opening Line from GM Slaviša Brenjo:
Ruy Lopez, Berlin Defense – Main Line with 9… Ne7

[Line 378 : 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. O-O Nxe4 5. d4 Nd6 6. Bxc6 dxc6 7. dxe5 Nf5 8. Qxd8+ Kxd8 9. Nc3 Ne7]

Early Knight maneuver Ne7-g6 in the Berlin Defense is the main area of interest that is covered in our Line 378. Similar to most Berlin lines, white has numerous possibilities, yet none of them offer tangible advantage.

10. h3 Ne7 is the most frequently played variation, and now White has two substantially different plans: queenside fianchetto of the dark-squared bishop or its deployment on the c1-h6 diagonal. An illustration of the former plan is 11. Ne4 h6 12. b3 a5 13. a4 c5 14. Bb2 Bf5, whereas an example of the latter could be 11. Be3 Ke8 12. Rad1 Be7 13. a3 Bd7 14. Rfe1 Rd8, like in a recent game A. Shirov – V. Kramnik, Zurich 2016.

Having an endgame on the board can be misleading, as both sides have to be careful not to miss tactical blows.

[Diagram: Black to Move] If Black plays 18… Ng5, White has 19. Bc1 with clear advantage, so Black has to find a different path to equalization.

NEW UPDATED OPENING LINE

[May 30, 2016] Updated Opening Line from GM Trajko Nedev:
Gruenfeld Defense, Russian Variation

[Line 148 : 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. Qb3]

After the almost obligatory 5… dxc4 6. Qxc4, Black has an interesting gambit continuation in 6… Be6 7. Qb5+ Bd7 7. Qxb7 Nc6, that could be unpleasant to meet for the unprepared players of White.

In the main 6… O-O 7. e4 Black has a few promising possibilities:

Hungarian Variation 7… a6 is covered in our Line 149.

Smyslov Variation 7… Bg4 8. Be3 Nfd7 has generally lost its popularity in the last decades, but it can still be occasionally seen nowadays on top level.

Somewhat similar to the Smyslov Variation is 7… Nc6 8. Be2 Bg4, where Black pieces exert pressure on White’s pawn center.

Prins Variation 7… Na6, popularized by Kasparov, is the most frequently employed variation among those covered in Line 148. White gets a passed pawn after 8. Be2 c5 9. d5 e6 10. O-O exd5 11. exd5, and Black usually continues with 11… Bf5, followed by Re8 and Ne4, with sufficient counterplay.

NEW UPDATED OPENING LINE

[May 30, 2016] Updated Opening Line from GM Aleksandar Kovačević:
Modern Benoni, Uhlmann & Knight’s Tour Variations

[Line 118 : 1. d4 Nf6 2. c4 c5 3. d5 e6 4. Nc3 exd5 5. cxd5 d6 6. Nf3]

Modern Benoni is one of the openings that chess players can’t be indifferent about – they  either love it or dislike it!

After 6… g6, one of the simplest set-ups for White is 7. Bf4, with the idea to meet the logical 7… Bg7 with an unpleasant check: 8. Qa4+. For that reason, Black usually proceeds with 7… a6 8. a4 Bg7, knowing that White’s main idea is 9. h3, followed by e2-e3, Be2 and O-O.

Uhlmann Variation (7. Bg5) is rarely seen nowadays, since Black can easily get a very comfortable play.

Knight Tour Variation (7. Nd2) is definitely one of the best options for White, and though it’s slightly preferable for him, it’s not without its venom. This line, just like many others in Modern Benoni, require not only good opening knowledge, but also a very accurate treatment from both sides.

We should also mention that the Fianchetto Line (7. g3) is covered in our Line 119, and Classical Variation (7. e4) in Line 120.

[Diagram: Black to Move] Black knight on g4 is under attack, but fearless Benoni players know that such pieces could sometimes be left hanging. So, Black to play and launch a strong attack!

NEW UPDATED ARTICLE

[May 29, 2016] Updated Opening Article by GM Boris Avrukh:
August 2015 Revisited: English Opening, Four Knights Variation with 4… Bb4 (12… d6)

In the original article our game of the week was D. Khismatullin – E. Tomashevsky, Chita 2015, featuring an important theoretical novelty. We have now updated the survey with several theoretically important correspondence and engine games, and there is also a highly relevant top-level game from the Chess World Cup 2015 with important improvements for both sides: J. Granda Zúñiga – A. Fier, Baku (m/2) 2015.

[Diagram: White to Move] Black wants to get rid of his opponent’s knight on f5, but perhaps White wants to sacrifice it himself 😉
