Opening his notes to this game for Chess Review (November 1960), Hans Kmoch writes: "In this game, Marsalek, whose name is Czech for only 'little marshall, ' launches a vehement sacrificial attack in the style of the big M himself. Nonetheless, Lombardy books the point with superb defense and counter-play."

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. a3 Bxc3+ 5. bxc3 c5

5... Ne4!? Botvinnik-Tal 1960

6. f3 Nc6

6... d5 7. cxd5 Nxd5

7. e4 d6 8. Be3

Kmoch suggests the following protracted Knight maneuver as one way to save the pawn at c4: 8. Ne2 O-O 9. Ng3 b6 10. Be2 Ba6 11. Nf1 Na5 12. Ne3 cxd4 13. cxd4 Rc8 but now Black can switch his focus from the pawn to White's unastled king. For example: 14. Qa4 d5! (14... Qc7 15. Bd2) 15. cxd5 Bxe2 16. Kxe2 exd5 17. e5 Nh5

8... b6

Fortifying the square in front of the doubled pawns. White will have great difficulty keeping the pawn at c4, which can now be attacked by Na5 and Ba6.

9. Bd3 O-O 10. Ne2 Ba6 11. Ng3 Rc8

12. f4!?

Playing now in "gambit style" since the pawn is obviously lost.

12. d5 Ne5 13. Bf4 Nfd7

12... cxd4 13. cxd4 Na5 14. e5 Ne8 15. O-O Bxc4

15... f5!

16. f5 dxe5

16... Bxd3 17. Qxd3 dxe5 18. fxe6 Nc4! (18... Rc7) 19. exf7+ Rxf7

17. fxe6 exd4 18. Bxc4 Rxc4 19. Nf5 fxe6 20. Nh6+

Desperation. But Black must play carefully:

20... gxh6 21. Rxf8+ Kxf8 22. Bxh6+ Ng7 23. Qg4 Rc7 24. Qxe6 Rf7 25. Rc1 Rf6

25... Kg8 26. Bxg7 Kxg7

26. Qc8

26. Qh3!?

26... Rd6 27. Qh3 Nc6 28. Bf4 Re6 29. Qxh7 Qe7 30. h4 Re1+ 31. Rxe1 Qxe1+ 32. Kh2 Ne5 33. Qh8+ Kf7 34. Qd8 Ne6 35. Qd5 Qxh4+ 36. Kg1 Qe1+ 37. Kh2 Qh4+ 38. Kg1 Qxf4 0-1

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 O-O 5. Bd3 d5 6. cxd5 exd5 7. Nge2 c6 8. O-O Re8 9. Ng3 Nbd7 10. a3 Bf8 11. e4 dxe4 12. Ngxe4 Nxe4 13. Nxe4 Nf6

White has a very active position to compensate for his isolated d-pawn.

13... Nb6

14. Bg5! Be7 15. Ng3?! h6 16. Be3 Bd6 17. Qd2 Ng4?!

17... Nd5

18. Bf4 Bxf4

18... Nxh2?! 19. Rfe1 Bxf4 20. Rxe8+ Qxe8 21. Re1! Qd8 22. Qxf4 Ng4 23. Bc4!

19. Qxf4 Qf6 20. Rae1 Rxe1 21. Rxe1 Be6 22. Nf5 h5 23. h3 Bxf5 24. Bxf5 Nh6 25. Re5 Rd8! 26. g4 hxg4 27. hxg4 Nxf5 28. gxf5 g5 29. Qe3 Kg7 30. Kf1 Rh8 31. Ke2 Rh4 32. Kd3

32... Rf4!

The weak f-pawn must fall.

33. b4 Rxf5 34. Rxf5 Qxf5+ 35. Kc3 g4 36. Kd2 Kg6 37. Qg3 Kg5!

Black effectively uses his King and the threat of forcing an exchange to snag more material.

38. Ke3 Qe6+ 39. Kd2 Qa2+ 40. Ke1 Qa1+ 41. Ke2 Qxd4 42. Qb8 Qc4+ 43. Ke1 b5 44. Qxa7 Kf5 45. Qc7 Ke4 46. Kd2 Qd5+ 47. Ke2 Kd4 48. Qa7+ Kc3 49. a4 bxa4 0-1

1. c4 g6 2. g3 Bg7 3. Bg2 e5 4. Nc3 d6 5. e4

Some people call this system "The Botvinnik Attack." White's idea is to first control the light squares and close the position with the idea of next fighting for the dark squares with either an f4 or b4 advance.

5... Nc6 6. Nge2 Nge7 7. d3 O-O 8. O-O Be6 9. Nd5

Taking this outpost is often a useful prelude to action since Black cannot happily capture at d5. The Knight demonstrates how White's light square control becomes the means of dark square attack.

9... Qd7 10. Bg5

Probing the dark squares and inviting Black's response.

10. Be3 Nd4!

10... f6?!

Better 10... f5 11. Qd2

11. Be3 f5 12. b4

12... a6

It is worth noting that Black cannot safely win material here:

a) 12... Bxd5 13. cxd5 Nxb4?! 14. Rb1 (14. Qb3?! a5 15. a3 Na6 16. Qxb7?? Rfb8) 14... c5 15. dxc6 Nbxc6 16. Qb3+ Rf7 17. Qxb7

b) 12... f4 13. gxf4 exf4?! (13... Nd4!?) 14. Nexf4! Bxa1? 15. Qxa1 Bxd5 16. Bh3! Qe8 17. cxd5

13. Rc1 Kh8 14. Qd2 Rf7 15. a4! Raf8 16. b5 axb5 17. cxb5!

The point of Rc1. We are always told to capture toward the center, but this way is justified by White's pressure on the c-file.

17... Bxd5

17... f4? 18. Bxf4 (18. bxc6 fxe3!) 18... exf4 19. bxc6 Nxc6 20. Ndxf4

18. exd5 Nd8 19. f4!

Necessary in order to blunt Black's kingside initiative.

19... b6 20. Rc4 Nc8

20... Nb7 21. Qc2 (21. Rfc1!? Nc5 22. fxe5 Nb3 23. e6! is also good.) 21... Rc8 (21... Nc5 22. fxe5 dxe5 (22... Bxe5?? 23. d4) 23. Bxc5) 22. Rc1 Nc5 23. fxe5 dxe5 24. Bxc5 bxc5 25. Rxc5

21. Rfc1 exf4 22. Nxf4 Re8

23. Bf2

Winning more quickly is 23. Qf2!! threatening Bxb6 or Rxc7 with a powerful queenside breakthrough, for example: 23... Rfe7 24. Rxc7 Qxc7 25. Rxc7 Rxc7 26. Bxb6 Rc1+ 27. Bf1 and White's connected passed pawns are unstoppable: 27... Rb1 (27... Nb7 28. Ne6) (27... Nxb6 28. Qxb6 g5 29. Ne2) (27... Ree1 28. Bxd8) 28. Bxd8 Rxd8 29. Ne6 Re8 30. Qc2

23... Rfe7 24. R1c2 Be5 25. h4!?

25. Qc1! gives White "Alekhine's Gun," which is an unstoppable weapon. 25... Bxf4 (25... c5 26. dxc6 Qa7 27. Nd5) 26. gxf4 c5 27. dxc6 Qa7 28. Qa1+

25... Kg7 26. Rxc7!?

Not the strongest breakthrough plan, but still winning, and more proof that White's position is simply overwhelming at this point.

26. Qc1!

26... Qxc7 27. Rxc7 Rxc7 28. Ne6+ Nxe6 29. dxe6 Ree7

29... Rxe6 30. a5! bxa5 31. b6 Nxb6 32. Bxb6

30. Bd5! Ra7 31. Qa2 Rec7 32. Bc6!

Denying Black all counterplay.

32... Ra5 33. Be1 Bd4+ 34. Kg2 Raa7 35. Qc4 Bf6 36. a5! Re7

36... bxa5 37. Bf2 Rab7 38. Qd5!

37. a6!?

White can win any way he pleases.

37. Bd7! simply picks up a piece.

37... Rac7 38. Bf2 h6 39. Qd5 Bc3 40. h5!?

Switching to the kingside.

40... Be5 41. Bd4 Bxd4

Black resigns rather than see somehting like 42.Qxd4+ Kh7 43.Qf6 gxh5 44.Qxf5+ (44.Bd7!?) 44...Kg7 45.Be4 and White has too many threats.

1-0

1. c4 e5 2. Nc3 d6 3. g3 f5 4. Bg2 Nf6 5. e3 Be7 6. Nge2 O-O 7. d3 Kh8 8. Rb1 Qe8 9. b4 Nc6

Black's Dutch-style set-up is solid and allows a natural kingside initiative to counter White's queenside pressure.

10. Nd5 Nxd5 11. cxd5 Nd8 12. O-O Bd7 13. f4 Bf6 14. Qd2

14. fxe5 Bxe5 15. Nf4 c6

14... Nf7

14... e4?! 15. dxe4 fxe4 16. Nc3 makes Black's pawns too static and creates a natural target at e4 for White.

15. e4 Nh6!? 16. Bb2

16... Qh5!

Black's plan is a direct kingside assault!

17. fxe5 dxe5 18. Bc1 Rf7 19. Nc3 f4! 20. Bf3 Bg4! 21. Qg2 fxg3 22. hxg3 Bg5! 23. Bxg4 Rxf1+! 24. Qxf1

24. Kxf1 Nxg4 25. Kg1 Rf8

24... Nxg4 25. Qe2 Rf8 26. Nd1??

This allows Black a gorgeous concluding shot.

White's only hope lay in 26. Bxg5 Rf2 27. Qxf2 Nxf2 28. Kxf2 Qxg5

 

 

26... Rf1+!!

17... e5! 18. Nf5 Bxf5 19. exf5

 

 

19... d5!

Taking cont rol of the center thanks to tactical threats, including ...Bc5 pinning the Queen and ...d4 forking Queen and Knight.

20. Qxe5?

White feels obliged to take one of the pawns or risk getting pushed back by their advance. But this allows Black tremendous activity.

a) 20. Qd2 exf4! (20... d4!?) 21. Nxd5 (21. Qxf4 Bc5+ 22. Kh1 Qxf4 23. Rxf4 Rfe8) 21... Nxd5 22. Bxd5 Rad8 (22... Bc5+!? 23. Kh1 Be3) 23. Kh1 Bf6 24. c3 Qc5 25. Rd1 Rfe8

b) 20. Kh2! Lombardy 20... d4 21. Qxe5 Qxe5 (21... Bd6 22. Qxd4) 22. fxe5 dxc3 23. exf6 Bxf6 and Black will have great difficulties trying to win the Bishops of opposite color ending.

20... Bd6 21. Qe2 Bxa3! 22. Nd1?

a) 22. bxa3 Qxc3

b) 22. Nxd5 is relatively best: 22... Qc5+ (22... Qa7+!?) 23. Kh1 Bxb2

c) 22. Nxb5? Bc5+

22... Rae8 23. Qf3?

Necessary was 23. Qd2 Rxe1 24. Rxe1 (24. Qxe1 Qxc2) 24... Bc5+ 25. Kh1 Ne4 26. Qxd5 Ng3+ 27. Kh2 Qxf4 28. Qe5 Nf1+ 29. Kh1 Qxf5! and Black wins only a pawn, e.g.: 30. Qxf5 Ng3+ 31. Kh2 Nxf5 32. Rf1 (32. Re5?? Bd6) 32... g6 though it is sufficient to win.

23... Bc5+ 24. Kh1 Rxe1 25. Rxe1

25... Qa5!

A surprising fork, which Spassky must have overlooked. Black must win a piece.

26. Nc3 b4

Not 26... d4?! 27. Ra1! and the threat of Bxf7+ saves the piece.

ChessBase mistakenly gives here 26... Bb4?

27. Nxd5 Qxa2 28. Nxf6+ gxf6 29. Qc6 Qc4

White resigns since he is down a full piece and it is his own King most likely to be in trouble following 30.Qxf6 Qxf4 threatening ...Bd6 etc.

24... Rxc7 25. Bxe6+ Kf8 (25... Kh8? 26. Bxd5 Ndb8 27. Qf4!) 26. Qf4+! Nf6 27. Bxd5 Bd3 28. Rcc1 Bb5 29. Ng5 and White has winning threats all over the board.

20. gxf4?? Qg4+ 21. Bg2 Qxg2#

20... Nd8 21. Nb2 e5 22. dxe6 Ndxe6 23. Nd3

Things would get very complicated after 46... Rxd4? 47.

I think White's King stops the pawns after 48. Ke3 f4+ 49. Kf2 e4? 50. a4! e3+ 51. Ke2 Ke6 52. a5! Kd5 53. a6 Kc6 54. b4 and White may actually win this one!!

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 Nbd7 7. Bc4 Qa5 8. Qd2 e6 9. O-O-O b5 10. Bb3 Bb7 11. Rhe1 O-O-O 12. f3 Be7 13. a3 Kb8 14. Be3 Rc8 15. Kb1 Rhd8 16. Ba2 Ne5 17. Nb3 Qc7 18. Qd4 Nc6 19. Qb6 Nd7 20. Qxc7+ Kxc7 21. Nd4 Nxd4 22. Bxd4 g5 23. Ne2 g4! 24. c4 gxf3 25. gxf3 Ne5 26. Bxe5 dxe5 27. cxb5 axb5 28. Nc3 Bc6 29. b4 Rxd1+ 30. Rxd1 Rg8!

Black has a clear edge due to his two Bishops and more active pieces.

31. Rc1 Kb6 32. Bb3 h5 33. Bd1 h4 34. Be2 Rg2 35. Rh1

35. h3 Rh2 36. Bf1 Bg5 37. Rd1 Bd2 38. Ne2 Rf2

Ra8 Kh7 34. Bxf7 Nd6 35. Bg8+ Kg6 36. Rf8! Nd3

The remaining moves very likely were made in time pressure as the players neared the control.

37. Kg1 Ne4?!

37... Nxb2?! 38. Nh4+ Kg5 39. g3 h5 40. f4+ Kh6 41. Bc4 Re1+ 42. Kf2 Re8 43. Rxe8 Nxe8 44. Bxb5

38... Ndxf2?

38... Nf4!

39. Bd5?!

39. Re6+!

39... Kf6??

40. Re6+ Kf5 41. Nd4+ 1-0

This is one of those positions you should practice winning against your computer. But first let's see Weinstein do it.

30. f3 Kd6 31. b4 f5 32. Kf2 Ke5 33. f4+! Ke6 34. g3 g6 35. e4! fxe4

35... Bxe4 36. Nxe4 fxe4 37. Ke3 Kd5 38. g4

36. Ke3 h6 37. g4 Bd7 38. Nxe4 Bb5 39. Kd4 Bf1

Winning another pawn.

51... Kf7 52. Nf5 Bh7 53. Nd6+ Kf8 54. Nxb5 1-0

1. d4 Nf6 2. c4 c5 3. d5 b5 4. cxb5 a6 5. bxa6 Bxa6 6. Nc3 g6 7. Nf3 Bg7 8. e4 Bxf1 9. Kxf1 d6 10. g3 O-O 11. Kg2 Na6 12. Nd2 Qc7 13. Nc4 Rfb8 14. Re1 Nd7 15. a3 Ne5 16. Qe2 Nxc4 17. Qxc4 Qb7 18. Nd1 Qb5

Black has won back his pawn, but White's initiative is worth more.

28... Ra1 29. Bh6

29. Rb7 Rc8 30. c4 f6 31. f4 Kf7 32. Bb2 Na6

32... Ne8 33. Kf3 Ra8 34. Ke3 (34. e5 Ra4) 34... Ra4 35. Kd3

33. Bc3 Rb8 34. Ra7 Rb3?

34... Nb4 35. e5 fxe5 36. fxe5 dxe5 37. Bxe5 Rb6 38. Kf3

35. Ba5!

White's pieces now combine to win a pawn.

35... Nb4 36. Bd8 Ke8 37. Bxe7 Rc3 38. Bxd6 Rxc4 39. Kf3

White wins faster with the immediate 39. e5!

39... Rc3+ 40. Kg2 f5 41. e5 Nxd5 42. e6 Nb6 43. Rxh7

and mate is unavoidable.

1-0

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Be2 O-O 6. Nf3 e5 7. d5 Nbd7 8. Bg5 h6 9. Bh4 g5 10. Bg3 Nh5 11. Nd2 Nf4 12. O-O Nc5 13. Nb3 b6 14. Re1 Nxe2+ 15. Qxe2 f5 16. exf5 Bxf5 17. Nxc5 bxc5 18. Rac1 Qf6 19. Ne4 Qg6 20. h3 Rab8 21. b3 Rf7 22. Rb1 h5 23. h4 gxh4 24. Bxh4 Bh6 25. f3 Rbf8

Gheorghiu now has an overwhelming attacking formation.

26. Kh1 Rg7 27. g3 Bc8 28. b4 Rgf7 29. bxc5 Rxf3 30. Rb8 Qg4 31. Rxc8

Desperation, but White has no better since Black's attack is overwhelming:

a) 31. Nf6+ R8xf6! 32. Bxf6 Be3!! (32... Qh3+ 33. Qh2 Rf1+ 34. Rxf1 Qxf1+ 35. Qg1 Qh3+ only draws.) 33. Qh2 (33. Rxc8+ Qxc8!) 33... Rxg3 34. Rxc8+ Kf7 35. Rxc7+ Kxf6 36. Rf1+ Bf4

b) 31. Qg2 Be3 32. Nf6+ R8xf6

31... Qxc8 32. Kg2

32. Qg2 Be3!

32... Qf5! 33. cxd6

Black now embarks on a series of attacking moves which basically sweep up all of White's major pieces. Unfortunately for Gheorgiu, however, he forgets to reapture this lowly pawn....

33... Re3!

Wins at least a piece, which will leave Black up a full Rook.

34. Qxe3 Bxe3 35. Rxe3 Qf1+ 36. Kh2 Rf2+?

Black likely was in time pressure.

36... cxd6!

37. Nxf2 Qxf2+ 38. Kh3 Qxe3??

Black is still winning after 38... cxd6

39. d7! Qf3 40. d8=Q+ Kh7 41. Qe7+ Kg8 42. Qe6+ Kh7 43. Qe7+ 1-0
