Modern Defense

In the modern defense, also Robatsch - defense (according to Karl Robatsch ), there is a opening of chess. It is one of the half- open games and is classified in the ECO codes under the key B06.

It begins with the moves:

1 e2- e4 g7- g6

The Modern Defence has independent significance when Black holds back the development of the knight on g8 and the Fianchetto the runner early pressure on the white pawn d4 based on g7. Additional pressure comes directly in contact with Sb8 - c6, e7 - e5, c7 - c5 or indirectly with the bondage of Nf3 Bg4 by.

Through restraining the knight on g8 White can take other options than in the Pirc Ufimtsev - defense, for example, also play c2 - c4 or c2 - c3.

Against white superstructure with optional 3rd or 4th Nb1 - c3 touted as the tiger Hillarp Persson after 3 ... d6 d7 a7 - a6 ... 4. The intended gain of space on the queenside with Sb8 - d7, c7 - c5 - b7 b5, b7 - Bc8. This structure is similar to the Hippopotamus opening.

With early Ng8 - f6 the game goes through diverter almost always in the Pirc Defense Ufimtsev or if White c2 - c4 has played in the King's Indian defense on.

Designation

Robatsch himself rejected the label from Modern Defence and preferred the term Robatsch - defense: "For some, technically not serious theorists attempting to train g6 as being an modern, invented by a collective opening. " Here, these theorists were based on games from the years 1965-1976 contrast Robatsch argues that was occupied by his own game material that he had used the opening already in the years 1945 to 1976 -. During a time in which this opening " had been " frowned upon and ridiculed.

Variants

The mostly used 2 train d2 -d4 by White, after a few moves lead to other opening systems:

  • 2 d2 -d4 Bf8 - g7 3 Nb1 - c3 d7 - d6 4 f2 - f4 - f6 Ng8 (conversion into the three- Bauer Attack of the Pirc Defense Ufimtsev, ECO B09 ) The standalone sequel c7 - c6 4 ... plans Sg1 -f3 - g4 Bc8 6 Lc1 -e3 pressure on the points d4 and b2 by 6 ... b6 after Qd8 - 5. 4 ... a6 a7 - also remains Modern Defence.
  • 4 Lc1 -e3 Ng8 - f6 (conversion into Pirc Ufimtsev Defense, ECO B07 ), other sequels: 4 ... a6 a7 -, eg Game example Sanakoev vs. Umansky or 4 ... c7 - c6.
  • 4 Sg1 -f3 - f6 Ng8 (conversion into the system of Classical Pirc Ufimtsev Defense, ECO B08 ) The stand-alone continued 4 ... Bc8 - g4 d4 is indirectly under pressure.
  • 4 h2 - h4 attacks directly. 4 ... Ng8 - f6 leads to the Pirc Ufimtsev - defense.
  • 4 ... Ng8 - f6 with reconciliation in the King's Indian Defence ( ECO E70- E99 ).
  • The stand-alone sequel Sb8 4 ... c6 with the possible consequence 5th Lc1 e3 - e7 - e5 6 d5 d4 Nc6 - e7 7 g2 - g4 f7 - f5 8 g4xf5 g6xf5 9 Dd1 - h5 Ne7 - g6 10 h4 e4xf5 Qd8 - 11 Dh5xh4 Sg6xh4 12 Nc3 b5 Ke8 -d8.
  • Which is also independent 4 ... e7 - e5. This can be attempted after 5 d4 -d5 f7 - f5 immediately, because after 6 e4xf5 g6xf5 7 Dd1 - h5 Ke8 -f8 Black will win with Ng8 - f6 a tempo and is superior in the center. After planning Black Qd8 - e8 - g6. 5 d4xe5 d6xe5 6 Dd1xd8 f2 - f4 Ke8xd8 7 directed against the black king.
