Basic position of the Taimanow variant
The Taimanow variant is a variant of the Sicilian Defense , an opening in the game of chess .
It is classified in the ECO codes under the keys B44 and B46 to B49 and is created according to the moves ( see also : chess notation ):
1. e2 – e4 c7 – c5
2. Ng1 – f3 e7 – e6 (Nb8 – c6)
3. d2 – d4 c5xd4
4. Nf3xd4 Nb8 – c6 (e7 – e6)
The moves e6 and Nc6 are interchangeable. The game can switch to the Scheveningen variant after an early d7 – d6 . The variant is named after the Soviet grandmaster Mark Taimanow , who played it often.
If Black leaves the d-pawn on d7, he can freely develop the f8 bishop, e.g. B. after c5 or b4. He can develop the other bishop to ... a7 – a6 and ... b7 – b5 to b7, where he controls the long diagonal.
The women's move to c7 is typical of the variant. From there the queen can attack both via the c-file and via the diagonal b8 – h2.
White can choose between the position- oriented Maroczy structure using 5. Nd4 – b5 d7 – d6 6. c2 – c4, and the development-oriented 5. Nb1 – c3.
5. Nb1-c3 Qd8-c7 6. Bf1-e2
is the main variant of the system. But White has many good alternatives here like 6. Bc1 – e3, 6. f2 – f4 or 6. g2 – g3. 6. Ndb5, on the other hand, is not so good: ... Qc7 – b8 followed by ... a7 – a6 and the knight is driven out again, but the queen is in good shape because she can now support the b-pawn in advancing. Ndb5 can be uncomfortable for Black. In the case of 6. g3 Nf6 ?! 7. Ndb5 Qb8 works. 8. Bf4. After that, the black d-pawn becomes backward . In Bobby Fischer - Michail Tal , Bled 1961, brought 8.… Ne5 9. Be2 Bc5 10. Bxe5 Qxe5 11. f4 Qb8 12. e5 a6 13. exf6 axb5 14. fxg7 Rg8 15. Ne4 Be7 16. Qd4 Ra4 17. Nf6 + White clear advantage.
6.… a7 – a6
prevents a white minor piece from moving to b5 and prepares b7 – b5.
7. Bc1-e3 Ng8-f6
Here Black can attack immediately on the queenside, e.g. E.g .: 7.… b7 – b5 8. Nd4xc6 Qc7xc6 9. 0–0 Bc8 – b7 10. Be2 – f3 Ra8 – c8.
8. 0-0 Bf8-b4
develops the bishop on an active square and threatens the knight on c3, who is defending the pawn on e4.
9. Nc3-a4
If Black now takes the pawn with Nf6xe4, White's development advantage becomes noticeable. The black king is at risk on e8. To defend the pawn with 9. f2 – f3 is too passive. After 9.… 0–0 and ... d7 – d5 Black is a little better.
9.… Bb4 – e7 pulls the bishop back to a safe square. The alternative is 9.… 0–0.
5. Nd4 – b5 Similar to the Svezhnikov variant , the knight wants to go on d6. 5.… d7 – d6 6. c2 – c4 This is a Maroczy structure that also occurs frequently in the accelerated kite . After Ng8 – f6 7. Nb1 – c3 a7 – a6 8. Nb5 – a3 there is a hedgehog position , which after b7 – b6 9. Bf1 – e2 Bc8 – b7 10. 0–0 Nc6 – b8 11. f2 – f3 Nb8– d7 has its framework.
Garry Kasparov found the Kasparov gambit named after him in this variant .
With the move order 2. Ng1 – f3 Nb8 – c6 3. d2 – d4 c5xd4 4. Nf3xd4 Qd8 – c7 5. Nb1 – c3 e7 – e6 White can bypass the Maroczy setup.
