Neven: Dutch Defence A80

1.d4 f5 2.Bg5

With the bishop move, which prevents ...e6 and makes 2...дf6 difficult (on account of 3.Bxf6!), there begins a simple repertoire against the Dutch Defence. NevenТs suggested line of play involves, in the critical lines, queenside castling for White. A80 Dutch Defence 2.Bg5

Erenburg: Modern Defence B07

1.e4 d6 2.d4 дf6 3.дc3 дbd7 4.f4 e5 5.дf3 exd4 6.Qxd4 c6 7.Be3 d5

With his first three moves, Black is mainly aiming for a Philidor Defence (4.дf3 e5), but in choosing them he has avoided certain lines. White can thwart BlackТs plans with 4.f4 and achieve something of an advantage in the variation with 8.dxc5. B07 Modern Defence 3...Nbd7 4.f4

Kuzmin: Sicilian Defence B92

1.e4 c5 2.дf3 d6 3.d4 cxd4 4.дxd4 дf6 5.дc3 a6 6.Be2 e5 7.дb3 Be7 8.0-0 0-0 9.жe1 Be6 10.Bf3

With this setup White causes Black enormous difficulties if he wants to play the advance Еd6-d5. His own game does suffer somewhat (the passive Bf3), but with some patient manoeuvring White can hope for an advantage. B92 Sicilian Najdorf 6.Be2 e5

Langrock: French Defence C11

1.e4 e6 2.d4 d5 3.дc3 дf6 4.e5 дfd7 5.f4 c5 6.дf3 дc6 7.Be3 cxd4 8.дxd4 Bc5 9.Qd2 0-0

With this third part the author concludes his series on the main variation of the Steinitz Defence. He demonstrates, e.g., how after both 10.0-0-0 a6 11.дb3 and 10.g3 Black can obtain a satisfactory game. C11 French Defence Steinitz 4.e5 ... 8...Bc5

Kritz: French Defence C11

1.e4 e6 2.d4 d5 3.дc3 дf6 4.e5 дfd7 5.f4 c5 6.дf3 дc6 7.Be3 cxd4 8.дxd4 Qb6

There is no doubt that the sub-variation 8...Qb6 does not represent the best setup for Black. But how does White then gain the advantage? Kritz shows you and in doing so goes into the early middlegame. C11 French Defence Steinitz 4.e5 ... 8...Qb6

Stohl: Ruy Lopez C77

1.e4 e5 2.дf3 дc6 3.Bb5 a6 4.Ba4 дf6 5.d3 d6 6.c3

The simple pawn move 5...d6 is the choice of the top players. Black is ready for ...дa5, so 6.c3 creates an escape route for the valuable Ba4. Stohl examines several moves for Black from the position in the diagram, including the popular fianchetto. C77 Ruy Lopez 5.d3 d6

Postny: Slav Defence D17

1.d4 d5 2.c4 c6 3.дf3 дf6 4.дc3 dxc4 5.a4 Bf5 6.дh4 Bc8 7.e3 e5 8.Bxc4 exd4 9.exd4

Top players such as Eljanov and Bacrot have recently been having good results with 6.дh4. If Black wants to hang on to the bishop pair, the retreat is indicated; therefore the evaluation of the position in the diagram is important for the whole variation. D17 Slav Defence 5...Bf5 6.Nh4

Marin: Bogo-Indian E11

1.d4 дf6 2.c4 e6 3.дf3 Bb4+ 4.Bd2 a5 5.g3 d5 6.Bg2 dxc4 7.Qc2 дc6 8.Qc4 Qd5

Here White is forced directly from the opening into the ending. Whether he at least gets something of an advantage is doubtful. In his meticulous way, Marin presents a promising system against 3.дf3. E11 Bogo Indian Defence 4.Bd2 a5

Krasenkow: Queen's Indian E12

1.d4 дf6 2.c4 e6 3.дf3 b6 4.a3 Bb7 5.дc3 d5 5.cxd5 дxd5 7.Qc2 дxc3 8.bxc3

In the third part of KrasenkowТs series on the Petrosian Variation (4.a3) we close in on BlackТs principal defence. The rapid ...c5 from the position in the diagram is the subject this time; White can count on a slight plus. E12 Queens Indian Defence 4.a3 ... 6.cxd5 Nxd5

Schipkov: King's Indian E84

1.d4 дf6 2.c4 g6 3.дc3 Bg7 4.e4 d6 5.f3 0-0 6.Be3 дc6 7.дge2 a6 8.Qd2 жb8 9.жc1

With the move 9.жc1 White prevents the planned ...b5 (9...b5? 10.cxb5 axb5 11.дxb5!) and 9...Bd7 is followed by 10.дd1. The idea is that 10...b5 will be followed by 11.c5 and after 11...dxc5 the rook can recapture: 12.жxc5 with an intact central position for White, but a weak c-pawn for Black. E84 Kings Indian Saemisch 6...Nc6

Karolyi: King's Indian E99

1.d4 дf6 2.c4 g6 3.дc3 Bg7 4.e4 d6 5.дf3 0-0 6.Be2 e5 7.0-0 дc6 8.d5 дe7 9.дe1 дd7 10.Be3 f5 11.f3 f4 12.Bf2 g5

What is typical here is queenside play for White and a black attack on the white king which has castled short. Players with White who know what they are doing have an excellent score. Karolyi presents the latest developments. E99 Kings Indian main line 10.Be3

Dembo: King's Indian E99

1.d4 дf6 2.c4 g6 3.дc3 Bg7 4.e4 d6 5.дf3 0-0 6.Be2 e5 7.0-0 дc6 8.d5 дe7 9.дe1 дd7 10.f3 f5 11.g4

White wants to protect his kingside with the paradoxical 11.g4, so that he can then throw into the scales his superiority on the other side of the board. Yelena Dembo presents this system through recent games by top players. E99 Kings Indian main line 10.f3 f5 11.g4
