Recommendations for your repertoire Papp: Benkö Gambit A58(Recommendation for Black)
1.d4 Nf6 2.c4 g6 3.Nf3 Bg7 4.g3 c5 5.d5 b5 6.cxb5 a6 7.bxa6 d6 8.Nc3 0-0 9.Bg2 Nbd7 10.0-0 Nb6 
| | The move order is quite deliberately not that of the original Volga Gambit. Because Petra Papp intends her repertoire suggestion for Black specifically as a weapon against the King’s Indian or the Grünfeld Defence with g3. It is very important for Black to delay the recapture on a6. |
Moskalenko: Dutch Defence A80 (Recommendation for Black)
1.d4 f5 2.Nc3 Nf6 3.Bg5 d5 4.e3 
| | Many players have realised that the capture 4.Bxf6 does not bring the hoped for results, see also the article in CBM 177. Therefore Viktor Moskalenko has also dealt with the solid alternative 4.e3. White wants to play Nf3, Bd3, Ne2 and then c4, but that is somewhat slow. |
Kosintseva: French Defence C11(Recommendation for White)
1.e4 e6 2.d4 d5 3.Nc3Nf6 4.e5 Nfd7 5.Nce2 c5 6.c3 Nc6 7.Nf3 
| | As Nadezhda Kosintseva demonstrates in her contribution, with best play Black should certainly be able to equalise against 5.Nce2. However, there is a great dearth of knowledge concerning the best plan for Black and a well prepared player with White can therefore count on having some chances. |
Kritz: French Defence C15(Recommendation for White)
1.e4 e6 2.d4 d5 3.Nc3Bb4 4.a3 Bxc3+ 5.bxc3 dxe4 6.Qg4Nf6 7.Qxg7Rg8 8.Qh6 
| | The move 4.a3 has no strong advocates at the moment. But Leonid Kritz shows that things are not quite so clear-cut and that in the position in the diagram Black actually has only one good move. But that knowledge does not appear to be very widespread. |
Kuzmin: Ruy Lopez C83(Recommendation for Black)
1.e4 e5 2.Nf3Nc6 3.Bb5 a6 4.Ba4Nf6 5.0-0 Nxe4 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.Nbd2Nc5 10.c3 Be7 11.Bc2 d4 12.Nb3 d3 
| | In games amongst the world elite, whenever the Open Ruy Lopez is played you can almost certainly count on the position in the diagram appearing. Alexey Kuzmin has investigated it and come to the conclusion that Black has good chances of equalising but that there is a great amount he needs to know. |
Sumets: Semi-Slav D46(Recommendation for White)
1.d4 d5 2.c4 c6 3.Nc3Nf6 4.e3 e6 5.Nf3Nbd7 6.Qc2Bd6 7.Bd3 0-0 8.0-0 e5 9.cxd5 cxd5 
| | The variation with 8...e5 is a very good drawing weapon. But you need to be prepared to defend a minimally worse endgame, which according to Andrey Sumets does not represent the correct strategy for everyone. White should be prepared to react flexibly. |
Marin: Grünfeld Defence D93(Recommendation for Black)
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Bf4Bg7 5.e3/Nf3 0-0 6.Nf3/e3 c6 
| | Here White apparently has the favourable version of a Schlechter Defence, because the bishop has already been developed to f4. But Mihail Marin points out in his article that the bishop is also exposed there and that Black thus has some additional possibilities. |
Ris: Grünfeld Defence D96(Recommendation for Black)
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3Bg7 5.Qb3 dxc4 6.Qxc4Be6 
| | It may be mostly White who wants to deviate from the deeply analysed variations in the Grünfeld Defence, but for Black too the necessity for extensive theoretical knowledge is of course just as much a problem. So Robert Ris suggest the as yet rarely played 6...Be6. |
Stohl: Nimzoindian E21(Recommendation for Black)
1.d4 Nf6 2.c4 e6 3.Nc3Bb4 4.Nf3 0-0 
| | Igor Stohl’s article deals principally with 5.Bg5 (5.e3 and 5.Qc2 would tend to transpose to other main systems). Then 5...c5 is a move which fits in well with the opening and according to our Slovakian author gives a satisfactory game. |
Krasenkow: King's Indian E94(Recommendation for White)
1.d4 Nf6 2.c4 g6 3.Nc3Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Na6 8.Re1 
| | Michal Krasenkow examines above all the two most important replies for Black, both 8...c6 and 8...Qe8. After them he considers White to have an advantage since “It is not easy for Black conjure up satisfactory counterplay”. |
