Recommendations for your repertoire Postny: English A33 (recommendation for Black)
1.c4 c5 2.Nf3 Nf6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 e6 6.a3 Bc5 7.Nb3 Bb6 
| | Instead of allowing Hedgehog positions with 7...Be7 8.e4, moving the bishop to b6 leads to quite different types of position (since 8.e4 0-0 9.Be2 can be met with 9...d5!). Evgeny Postny sees Black as having equalised and thinks that 6.a3 will perhaps disappear from practice. |
Iotov: Alekhine Defence B02 (of interest for White and Black)
1.e4 Nf6 2.e5 Nd5 3.c4 Nb6 4.c5 Nd5 
| | The Chase Variation is actually considered harmless. But in his article Valentin Iotov shows that with 5.Nc3 e6 6.d4 White can bring about extremely sharp positions. Both sides have the option of leaving the path which transposes to the Alapin Variation (Sicilian). |
Krasenkow: Modern Defence B06 (recommendation for Black)
1.e4 g6 2.d4 Bg7 3.Nc3 c6 4.Bc4 d6 
| | At the heart of Michal Krasenkow’s article there is the continuation 5.Qf3 e6. After it play is of a very forcing character. Black needs to know what he is doing, but if he does he has no difficulties in achieving a level game. |
Szabo: Sicilian Defence B76 (recommendation for White)
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 0-0 8.Qd2 Nc6 9.g4 Nxd4 10.Bxd4 Be6 
| | By first playing 9...Nxd4 Black avoids the 9...Be6 10.Nxe6 variation. On the other hand, in the position in the diagram White must not castle long but can play more flexibly. But according to Krisztian Szabo’s analyses, it is not clear whether 9...Nxd4 is better than the alternative. |
Neven: French Defence C11 (recommendation for Black)
1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.f4 c5 6.Nf3 Be7 7.Be3 0-0 
| | By choosing this move order Black delays Nb8-c6 and is planning 8...b6 on his next move. Then he no longer has to fear d4xc5 and moreover has ...Ba6 up his sleeve. Knut Neven analyses the variation and also presents ideas for Black after the aggressive 9.h4. |
Kosintseva: French Defence C17 (recommendation for White)
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.Bd2 
| | So far the Bogoljubow move 5.Bd2 has been considered really harmless, but the new trend is towards 5...Ne7 6.a3! As Nadezhda Kosintseva convincingly points out, White then has very good chances of an opening advantage. |
Papp: French Defence C18 (recommendation for White)
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Qa5 7.Bd2 Qa4 8.Qg4 
| | Petra Papp has an aggressive plan against the popular variation with 6...Qa5: 8.Qg4 and after Black has protected the g7-pawn the queen does not return to d1 and the c2-pawn is not defended. Black appears to have problems here. |
Sumets: Slav Defence D16 (recommendation for Black)
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 e6 6.e3 c5 7.Bxc4 Nc6 8.0-0 cxd4 9.exd4 Be7 10.Qe2 0-0 11.Rd1 
| | The variation with 5...e6 and a subsequent c6-c5 should not be under-estimated. Black may well lose a tempo, but a4 is not necessarily useful. Andrey Sumets cannot see any opening advantage for White. |
Ris: Queen’s Gambit Accepted D27 (recommendation for White)
1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.e3 e6 5.Bxc4 c5 6.0-0 a6 7.Nc3 b5 8.Be2 
| | Putting the bishop on e2 has, above all in the lines with d4xc5 and an early exchange of queens, the advantage that pressure is being exerted on the a6-b5 pawn chain. Robert Ris is very optimistic for White, though he admits that Black gains equality with precise play. |
Marin: Slav Schlechter Variation D94 (recommendation for Black)
1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 g6 5.Nf3 Bg7 6.Be2 0-0 7.0-0 a6 
| | With 7...a6 Black prepares an immediate ...b5, but also ...dxc4 followed by ...b5. Mihail Marin then examines several continuations for White, none of which, however, is suitable for offering White an opening advantage. |
Kuzmin: King's Indian Fianchetto E62 (recommendation for Black)
1.d4 Nf6 2.c4 g6 3.Nf3 Bg7 4.g3 0-0 5.Bg2 d6 6.0-0 Nc6 7.Nc3 e5 8.d5 Nb8 
| | This variation was previously played with 8...Ne7, but as Alexey Kuzmin explains in his article, c5 is the ideal square for this knight and it is better reached via b8. Surprisingly, White then has hardly any chance of an opening advantage. |
