Position after 8. 0–0–0
In chess , the Richter-Rauser attack is a variant of the Sicilian Defense , an opening in the game of chess. It is classified in the ECO codes under the keys B60 to B69.
It starts with the move sequence 1. e2 – e4 c7 – c5 2. Ng1 – f3 d7 – d6 3. d2 – d4 c5xd4 4. Nf3xd4 Ng8 – f6 5. Nb1 – c3 Nb8 – c6 6. Bc1 – g5 .
The move 6. Bg5 was introduced by the German master Kurt Richter and Wsewolod Alfredowitsch Rauser , each with a different motivation. One of the ideas behind this move is directed against a possible black advance in the center with e7 – e5. Black very often plays 6.… e7 – e6 in order to prevent a double pawn on the kingside . 6… Bc8 – d7, which intends to quickly turn on the rook with Ra8 – c8, is less common. The half-open g- file resulting from the double pawn would be used by Black for pressure play on the kingside, e.g. B. 7. Bf1 – e2 Qd8 – a5 8. Bg5xf6 g7xf6 9. Nd4 – b3 Qa5 – g5
more 7. Qd1 – d2 Bf8 – e7 8. 0–0–0 0–0 9. Nd4 – b3 builds a column of pressure the d-line on.
Modern treatments reset the black 0–0. Instead, the pressure column in the d-file is defused by 7.… a7 – a6 or Nc6xd4. After 8. 0–0–0 Black has several options:
- With the immediate development of Black's queenside 8.… Bc8 – d7 9. f2 – f4 b7 – b5 Black takes with 10. Bg5xf6 g7xf6, or with 9.… Bf8 – e7 10. Nd4 – f3 b7 – b5 with 11. Bg5xf6 g7xf6 doubled f-pawns in buy.
-
8.… h7 – h6 attacks the bishop.
- 9. Bg5 – f4 puts pressure on the pawn on d6. After 9.… Nc6xd4 ?! 10. Qd2xd4 e4 – e5? White moves 11. Bf4xe5! So Black continues with 9.… Bc8 – d7.
- 9. Bg5 – h4 Nf6xe4 loses a pawn. Since Black is good both after 10. Bh4xd8 Ne4xd2 and after 10.Nc3xe4 Qd8xh4. Therefore White plays 10. Qd2 – f4 Ne4 – g5, after which he has compensation for the pawn.
- 9. Bg5 – e3 Bf8 – e7 10. f2 – f4 Nc6xd4 the immediate 10.… b7 – b5 fails on 11. Nd4xc6. 11. Be3xd4 b7-b5
- 9. Nd4xc6! This continuation poses significant problems for those who follow suit. Although White thus strengthens the black center (the advance ... d6 – d5 is now easier to enforce), practice has shown that after 9.… bxc6 10. Bg5 – f4 d6 – d5 11. Qd2 – e3 White's active piece play begins harbors attack potential that should not be underestimated.
-
8.… 0–0
- After 9. Bg5xf6 Be7xf6! 10. Nd4xc6 Bd7xc6 11. Qd2xd6 Qd8 – b6 White has won a pawn, but Black's pieces are very active.
- 9. Nd4 – b5 Qd8 – a5 10. Bg5xf6 Be7xf6 Nb5xd6 Rf8 – d8 also wins a pawn, but the d6 knight is pinned.
- 9. f2 – f4 increases the influence in the center
- 9. Nd4 – b3 increases the pressure on the d6 pawn.
