Positional Concept: Maneuvering Against Weaknesses

This "maneuvering against weaknesses" study is in 2 parts:

Play against a weak pawn/square

Play Against 2 Weaknesses

First a definition. What is a "weakness?" A weakness is a point in the enemy position that can be attacked. If it cannot be attacked then it is not a true weakness. Just because a pawn is doubled, backward or isolated doesn't in itself mean its weak, its only weak if it can be attacked.

Part 1 Play against weak pawns/squares

This first example is from the play of a then 13 year old Bobby Fischer it demonstrates in the simplest way the idea of play against a weakness. This game ends in a hard fought draw but the idea is more important than the result.

In the next game black leaves himself with a weak pawn which white is able to attack.

In the section on "Restraint" we saw one game that demonstrated the idea of restraining the advance of a pawn majority and then attacking them by a "minority attack." This next game shows the use of the minority attack to create a pawn weakness in the enemy position which then becomes the object of attack.

This following game demonstrates when doubled pawns are a weakness and how to maneuver against them.
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 c5 5.a3 Bxc3+ 6.bxc3 Nc6 7.Bd3 O-O 8.Ne2 b6 9.e4 Ne8 10.Be3 d6 11.O-O Na5! Black has no weaknesses in his camp and is well positioned to defend his kingside. White however has a pawn weakness at c4 which can be attacked. 12.Ng3 Ba6 13.Qe2 Qd7! A strong move. The Black Queen can now go to a4 to increase pressure on c4 and also allows black to play...f5. 14.f4 f5! Black is no hurry to win the c-pawn. The text suppresses whites threats on the b1-h7 diagonal and helps to ensure the defense of his kingside once this is achieved he can win the c4 pawn and with it the game. 15.Rae1 g6! White has no clear object of attack on the kingside while whites queenside weaknesses are permanent pawn structure defects. 16.Rd1 Qf7 17.e5 Rc8 *if 18. exd6 Nxd6 and the c5 pawn is defended* 18.Rfe1 dxe5! 19.dxe5 Ng7 Blacks kingside is a fortress 20.Nf1 Rfd8 21.Bf2 Nh5! 22.Bg3 *Not 22.g3 as this would lead to defeat along the h1-a8 diagonal after 22...Qe8 23...Qc6 and 24...Bb7* 22...Qe8 23.Ne3 Qa4 Now Black has achieved a strong Q-side atack while stifling his opponent 24.Qa2 Nxg3 25.hxg3 h5 26.Be2 Kf7 27.Kf2 Qb3 28.Qxb3 Nxb3 29.Bd3 Ke7 30.Ke2 Na5 31.Rd2 Rc7 32.g4 Rcd7 33.gxf5 gxf5 34.Red1 h4 35.Ke1 Nb3 36.Nd5+ exd5 37.Bxf5 Nxd2 38.Rxd2 dxc4 39.Bxd7 Rxd7 40.Rf2 Ke6 41.Rf3 Rd3 42.Ke2 0-1 Botvinnik-Reshevsky, The Hague, WC tournament 1948

The creation and control of weak squares is one of the major themes of chess because weak squares affect the strength of your pieces according to GM Yasser Seirawan in "Winning Chess Strategies." The next game demonstrates this idea of creating and playing against weak squares.
1. c4 c5 2. b3 Nf6 3. Bb2 g6 4. Bxf6! creating a weakness at d5 which he hopes to exploit. 4…exf6 5. Nc3 Bg7 6. g3 Nc6 7. Bg2 f5 8. e3 O-O 9.

Here is one more example of the creation of a weak square, which is used to create additional targets in the enemy camp.
1. e4 e6 2. d3 c5 3. Nf3 Nc6 4. g3 g6 5. Bg2 Bg7 6. O-O Nge7 7. c3 O-O 8. d4 d6 9. dxc5 White makes this simple capture to draw blacks d-pawn from d6 which allows white to advance his e-pawn and obtain a grip on d6 and f6 squares 9…dxc5 10. Qe2 b6 11. e5! The point. White now plans Bf4 helping to control d6 or Bg5 (aiming at f6), as well as moves like Nge2, and Rd1 with all his pieces aiming at the strategic weak point at d6. Black must try to prevent this plan or achieve counterplay.11…a5 12. Re1 Ba6 13. Qe4 Ra7 14. Nbd2 Bd3 15. Qh4 Nd5 16. Qxd8 Rxd8 17. a4 Rad7 18. Bf1 Bxf1 19. Kxf1 Nde7 20.

Play Against 2 Weaknesses

In the last example above we saw Fischer create a weak square (d6) and then use pressure to eventually attack a second enemy weakness (the b6 pawn). This is a good lead in to the subject of Nimzovich's theory on the "2 theatres of war."
The idea of play in 2 theatres of war (similarly) is explained thusly by Nimzovich, "we engage one wing, or the obvious weakness in it, and thus draw the other enemy wing out of its reserve, when new weaknesses will be created on the reserve wing, and so the signal is given for systematic maneuvering against those two weaknesses."
IM Silman states in "Complete Book of Chess Strategy," "The principle of two weaknesses states that the creation of a second weakness (or advantage) stretches the enemy's ability to resist to unmanageable proportions."
Here is a good example of Nimzovich "2 theatres of war" from one of his games:
1. e4 Nc6 2. Nf3 e6 3. d4 d5 4. exd5 exd5 5. Bg5 Be7 6. Bxe7 Qxe7+ 7. Qe2 Bf5 8. c3 Be4 9. Nbd2 O-O-O 10. O-O-O Nh6 11.

Here is another example of play against 2 weaknesses.
1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. Nc3 Nf6 5. d3 d6 6. Bg5 Na5 7. Bb3 Nxb3 8. axb3 Be6 9. Na4 h6 10. Bh4 Bg4 11. Nxc5 dxc5 12.h3 Bxf3 13. Qxf3 Qd6 14. Bxf6 Qxf6 15. Qxf6 gxf6 Black has doubled f-pawns that can be immediately attacked by O-O and f2-f4 16. Ra5! Stronger than the immediate attack against the f-pawns. White Forces a second permanent weakness on a7. Black now has 2 serious weaknesses the doubled f-pawns and a7. *16. O-O Ke7 17. f4 h5 18. Rf2 Rh7 19. Raf1 and Black can defend the one weakness on the f-file.* 16... b6 17. Ra6 Kd7 18.

A very clear example of play against 2 weaknesses can be seen in the following game:
1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Be7 5. e3 O-O 6. Nf3 Nbd7 7. Qc2 c5 8. Rd1 Qa5 9. Bd3 h6 10. Bh4 cxd4 11. exd4 dxc4 12. Bxc4 Nb6 13. Bb3 Bd7 14. O-O Rac8 15. Ne5 Bb5 16. Rfe1 Nbd5 17. Bxd5 Nxd5 18. Bxe7 Nxe7 19. Qb3 Bc6 20. Nxc6 bxc6 21. Re5 Qb6 22. Qc2 Rfd8 there are two isolated pawns: which is weaker? 23. Ne2 Rd5 24. Rxd5 cxd5 now there is only one. It is not exposed on a half-open file, so can White defend? 25. Qd2 Nf5 26. b3 h5 27. h3 h4 a typical preparatory probe 28. Qd3 Rc6 29. Kf1 g6 30. Qb1 Qb4 Black's pressure on the d-pawn cannot be increased. So Black opens up a new point of attack. 31. Kg1 a5 32. Qb2 a4 33. Qd2 Qxd2 34. Rxd2 axb3 35. axb3 Rb6 36. Rd3 Ra6 37. g4 hxg3 38. fxg3 Ra2 39. Nc3 Rc2 40. Nd1 Ne7 41. Nc3 Rc1+ 42. Kf2 Nc6 43. Nd1 Rb1 Black has his two points of attack. 44. Ke2 *44. Ne3 Na5 picks up the b-pawn as well* 44... Rxb3 45. Ke3 Rb4 46. Nc3 Ne7 47. Ne2 Nf5+ 48. Kf2 White still has two points to defend. 48... g5 49. g4 Nd6 50. Ng1 Ne4+ 51. Kf1 Rb1+ 52. Kg2 Rb2+ 53. Kf1 Rf2+ 54. Ke1 Ra2 55. Kf1 Kg7 56. Re3 Kg6 57.

Lastly here is one final example showing how play against 2 weaknesses can create further weaknesses.
