Queenstown Open 2016 Round 3

Today we will look at one of my games from the recently concluded Queenstown Open 2016. As in many QGD games, it features the typical attack and breakthrough on the open c-file.


Checkerboard 5 vs Opponent
Queenstown Open 2016 Round 3

1. d4 d5
2. c4 e6
3. Nc3 Nf6
4. e3 Be7
5. Nf3 O-O
6. Be2 b6
7. O-O Bb7
8. cxd5

This open c-file will become an important part of White's middlegame plans.

9... exd5
9. b3 Nbd7
10. a4

The idea is to play Ba3 trading White's bad bishop.

10... a6
11. Ba3 Bxa3
12. Rxa3 Qe7

The drawback of 10. a4 is that is allows Black to develop with threat.

13. Ra1 Rfd8 (D)

Position after 13... Rfd8

14. Qc2?

Losing tempo. 14. Qb1 Rac8 15. b4 gets the pawn forward in time to stop c5.

14... Rac8

White must waste time moving his queen again, giving Black the opportunity to play c5.

15. Qb2 Ne4!?

I was expecting 15... c5 16. Rfc1 (16. dxc5 bxc5 Black has the strong threat of 17... d4 creating a passed pawn.) 16... c4 (Not 16... cxd4? 17. Nxd4 when White has a good blockade against the passed pawn.) 17. Na2 cxb3 (17... b5? 18. axb5 axb5 19. bxc4 Both b5 and b7 are hanging; White will win at least a pawn.) 18. Qxb3 Ne4 19. Nc3 Ndf6 (D)

Position after 19... Ndf6

Black has an isolated pawn, but is compensated with active pieces and more space in the centre. He needs to get his bishop into the game and use the outpost on c4 to his advantage. White will try to find counterplay on the c-file as well.

16. Rfc1

White does not capture on e4 straightaway. He doubles his rooks on the c-file first to strengthen the upcoming breakthrough.

16. Nxe4 dxe4 17. Nd2 c5 Black is the one controlling the c-file.

16... Ndf6

Is it still possible to play c5? 16... c5 17. Na2 Ndf6 (threatening Ng4) 18. Ne5 White holds for now, but his position is getting cramped.

17. Rc2 g6?

This only gives White more time to execute his plan.

18. Rac1 Qd6
19. h3 Re8 (D)

Position after 19... Re8

The tides are turning. Black had his chance to make a c5 pawn break, but it becomes more remote with each move. Instead, White is allowed to strengthen his forces on the c-file in prepration for a counterattack. With the rooks doubled, now is the time to take on e4.

20. Nxe4 Nxe4

20... dxe4 21. Ne5 Nd7 22. Nxd7 Qxd7 23. a5 bxa5 24. Rc5 with Qc4 to follow, targeting the weaknesses on a5, a6 and c7.

21. Ne5

The destination is c6. Note the passive position of Black's bishop.

21... Nf6
22. Nc6 Kg7
23. b4 Ra8
24. a5!

Provoking more weaknesses. Not 24. b5? a5 allowing Black to patch up his weak spots.

24... b5
25. Ne5 (D)

Position after 25. Ne5

By forcing Black to push b5, White can use c5 as an invasion point.

25... Re7.
26. Bf3

Before the rook advances, the knight must be stopped from coming to e4. (26. Rc5? Ne4)

26... Rc8
27. Rc5 c6!

The best defense, seeking protection of the bishop while allowing ... Rec7 and ... Nd7.

28. Qc2 Rcc7?

Hastening the breakthrough.

28... Rec7 had to be played; 29. Bg4 Nxg4 30. Nxg4 f6 while Black is still inferior due to his passive pieces, White would need a long siege to breach the defences: 31. f3 with the idea of centralizing the king and pushing e4 while Black's forces are tied down.

29. Nxc6 Bxc6
30. Rxc6 Rxc6
31. Qxc6 (D)

Position after 31. Qxc6

The breakthrough.

31... Qxb4
32. Qxa6 Qb2
33. Rc5 Qa1+
34. Kh2 b4
35. Rb5 Qa3
36. Qb6 Qb2
37. Rxb4

The passed a-pawn will prove decisive.

37... Qxf2
38. Rb3

Be careful! 38. a6? Rxe3 followed by ... Rxf3 and suddenly it is White's king that's in trouble!

38... Rxe3
39. Rxe3 Qxe3
40. Qb2!

Dashing any of Black's hopes for a perpetual.

40. a6? Qf4+! 41. Kg1 Qc1+ White cannot escape from the checks.

40... Qf4+
41. Kh1 Qc7
42. Qa3 Qa7
43. a6

By now Black had run into time trouble, so he resorted to waiting moves.

43... Kg8

Was it still possible to fight back? 43... Ne4 44. Qa5 (44. Bxe4 dxe4 White must give up his passed pawn to stop Black's.) 44... Ng3+ 45. Kh2 Qb8 complicates things a little but after 46. a7 Nf1+ 47. Kh1 Black can resign.

44. Qa5 Kg7
45. Qb5 (D)
1-0

Position after 45. Qb5

With 46. Qb7 to follow. So what can we learn from this game?

  1. Make sure every move you make has a purpose. Unecessary moves only give your opponent more time to execute his/her plans.
  2. When there is an exchange available you don't have to capture immediately; sometimes it is better to wait till the right moment before releasing the tension.
  3. Even if you're winning, watch out for perpetual checks!
