[D17] Slav Defence: 5 a4 Bf5

Maneuvering of pieces to good squares, files, ranks or diagonals is an important aspect in middle game play. With active and strong pieces, coupled with proper coordination, one can have the initiative. The study in the art of maneuvering of pieces also requires knowledge on positional elements, strategy of good piece play and planning. The following game is an account of what transpired in a normal game between grand masters. What I would like to show here is how Black improve his position by bringing the pieces into good squares and to further improve the position by creating support points and operational base for advance pieces deep inside enemy territory. After attaining positional advantage then exploitation of enemy's weakness becomes an easier task.

[The text move is an imrprovement to 12.Bg5 which was played by Kuzubov against Rublevsky in Warsaw Poland, 2005. The game continued: 12...g6 13.Qc2 Bg7 14.0-0-0 Nf6 15.h4 Nfd5 16.Nxd5 Qxd5 17.Re1 0-0-0 18.Bxe7 Qa2 With Black having initiative in the queenside.]

12...Nf6
[12...cxd5 Favors White as in Nguyen Chi Minh (2381)-Savchenko,S (2510)/Longeville-les-Metz FRA 2011/1/2-1/2 (26) 13.Nxd5 e6 14.Nxb6 Bb4+ 15.Bd2 Qxb6 16.Bb5 Qe3+ 17.Kf1 Qxd2 18.Qxd2 Bxd2 19.fxe6 fxe6 20.Bxd7+ Kxd7 21.Rd1 Ke7 22.Rxd2 White having better pawn structure. ]

13...Nfxd5 14.Nxd5 Nxd5 15.Qxb7 Rc8 16.Bd2 g6
To remove enemy unit occupying Black's territory and at the same time clearing g7-square for the dark-squared bishop. . Here, White has slight advantage because of better pawn structure and bishop pair.

17.Ba6
[17.Rc1!? Qd7 (17...Bg7 18.fxg6 hxg6 19.Bb5= ) 18.Qxd7+ Kxd7 19.Bxa5 Ra8 20.b4 gxf5 Black's position is more promising as he can have active play in the center.]

17...Rc7 18.Qb3 Qa8 19.Bc4 Rd7
[19...Bg7 is also playable 20.Bxd5 cxd5 21.Qb5+ Qc6 22.Ke2 0-0 Black's position is safer.]

20.Bc3 Rg8 21.f6?!
The move appears strong at a glance but this gave Black opportunity to build a fortress for his king. [The simple 21.fxg6 will enable White to maintain the initiative. 21...hxg6 22.0-0 White is better here because of the Black king's situation. ; Or even 21.Rd1 maintains White's positional advantage because of the pressure on d-file. ]

21...Rb7 22.Qa2 e6 23.0-0 Bd6
The dark-squared bishop is now active. [The exchange 23...Nxc3?! will only reduce Black's defences. 24.bxc3 Qd8 25.Rab1 Rxb1 26.Rxb1 ]

24.f4
[24.Rfe1!? Qd8 25.Rad1+/= White maintains the pressure in the center. ]

24...Qb8=
[24...Bxf4 25.Rae1 Qb8 26.Bxd5 cxd5 27.Qxd5+- ; 24...Ne3!? 25.Rfe1 (25.Rf2 g5 with good counterplay for Black.) 25...Nc2 26.Bxe6 Kf8 27.Rad1 Bc5+ 28.Kh1 Nxe1 29.Rxe1 fxe6 30.Qxe6 Rf7 It would be difficult for White to prove that the scrifice is correct.]

25.Rae1 Kd7
The Black king must look for a safer place as the pressure along the e-file is increasing.and the possibility of a combination at e6. . [25...Nxc3 26.bxc3 Rb2 27.Qa1= ]

26.Re4
[To lure Black in capturing f4 will have double edge complication, e.g.: 26.Re2 Bxf4 (26...Nxf4 This line is bad for Black 27.Rxf4 Bxf4 28.Bxe6+ Kd6 29.Re4 White has dangerous attack ) 27.g3 Qa7+ (27...Bxg3 28.hxg3 Qxg3+ 29.Rg2 Qe3+ 30.Kh1+- ) 28.Kh1 Bd6 And Black is okay. (28...Nxc3? is inferior since it leads to 29.bxc3 Bd6 30.Bxe6+ Kc7 31.Bxf7+- ) ]

26...Qa7+
[26...Nxc3!? 27.bxc3 Rb2= ]

27.Kh1+/= Rgb8
Finally, Black succeeded in bringing all his pieces into active position and as a result, Black has the inititive now.

28.Bd4 Bc5 29.Be5 Bd6 30.b3 Bxe5 31.fxe5 Qc5
Covering Black's potential weakness in the a3-f8 diagonal and the Black Queen is more actice here. [31...Rd8 32.Rc1+/= ]

32.Qd2 h5 33.Rc1 Qb4 34.Qc2
[34.Qh6 Qa3 ]

34...Qb6+/= 35.Re2
[35.Qd3 Rd8+/= ]

35...Rd8
In reality, the b3-pawn is not a weakness because it could be effectively protected. It is necessary that Black should shift concentration of his forces to the d-file as it is the only open file.

36.Qe4
[36.Rd2 Rc7= ]

36...Rc7 37.Rd2 Kc8 38.h3 Kb8 39.Kh2 Rcd7 40.Rd3 Nb4
Challenging White's control over d-file.

41.Rxd7 Rxd7 42.Rf1 c5
And Black creates a new operational base at d4.

43.Qf4 Nc2 44.Rf2 Nd4
The knight is very strong in its new base and now the b3-pawn can become a good target.

45.Bd3
Looking for new tactical opportunity like Bxg6. [45.Rd2 Qb4 46.Rd1 Qc3= ]

45...Rd8=/+
[Inferior is 45...Nxb3 46.Bxg6 c4 47.Bxh5= ]

46.Be4 Qc7 47.Rd2 Ka7
[47...Nxb3?? Allows White to implement his planned combination. 48.Rxd8+ Qxd8 49.Bxg6+- ]

48.h4 Rb8
The weakness to the b3-pawn is now real.

50.Re3?
[>=50.Kh3!?=/+ Rxb3 51.Rxb3 Nxb3 52.Bxg6 c4 53.Bxf7 Qxf7 54.Qxc4 And White has good drawing chances. ]
