Round 5: Hebden beats Ernst

Mark Hebden is the sole leader again at the 4th Batavia tournament, with 4 rounds to go. In the 5th round the English grandmaster beat Sipke Ernst in what our chess program calls a “Semi-Benoni”. Hugo ten Hertog and Achim Illner both won and kept good chances to score an IM norm. On Wednesday, the latter only needed 12 moves to draw with Robin van Kampen while the other participants enjoyed their rest day.

Let’s start with the clash between the tournament leaders.

Hebden – Ernst

1. d4 c5!?
A sign that Ernst was (also) playing for a win.
2. d5 e5 3. e4 d6 4. Nc3 a6 5. a4 g6 6. Be2 Bg7 7. Nf3

7 … f5!?N
With the pawns on a2 and a7 this early push would be tricky because of Bb5+ followed by Ng5 and White will use the e6 square for his knight.
8. Nd2 Nf6 9. Nc4 O-O 10. a5!?
A long-term positional pawn sacrifice.
10 … Nxe4 11. Nxe4 fxe4 12. Be3 Qc7 13. Nb6 Ra7

14. h4
Playing on two wings. 14. b4!? was also strong.
14… Nd7 15. Nxc8 Qxc8 16. Bg4

It’s clear that Black’s opening choice has not been successful.
16 … Rf5!?
Better than to allow the bishop to e6.
17. h5!
White goes for more.
17 … Nf6 18. hxg6 hxg6

19. b4!?
Not bad, but 19. Bxf5 was probably just winning: gxf5 (19… Qxf5 20. b4) 20. Bg5! Qe8 (directed against Qd1-h5) 21. Bxf6 Bxf6 22. Qh5! (anyway!) 22 … Qxh5 23. Rxh5 f4 24. Ra4.
19… Ra8 20. bxc5 dxc5
White can still take on f5 and play Bg5 here and on the next move.
21. c4 Qc7 22. Be2 Rf8 23. Qb1 Rf7 24. Ra3 Rf4 25. g3 Rf5 26. g4 Rf4 27. Bxf4 exf4 28. g5 Nh7 29. Qxe4 Nxg5 30. Qe8+ Rf8 31. Qxg6 Qe5 32. Rg1 Re8

33. Qxe8+?
There was nothing wrong with 33. Qc2 because after 33 … f3 White has 34. Re3 Qa1+ 35. Bd1.
33… Qxe8 34. Rxg5 Qe4
Normally this should end in a draw but White keeps the better chances.
35. Kf1 Qb1+?!
35… Qh1+ 36. Rg1 Qh7 and it’s hard for White to make progress.
36. Kg2 Qb2? 37. Rf3!

Two careless checks and Black is facing a lost position again.
37 … Qd2
Of course the idea was 37… Qxe2 38. Rxf4 and White will win the black bishop.
38. Bd3 Kf7 39. d6 Bd4 40. Rd5 Ke8 41. Bf5 Kd8 42. Bg4 Ke8 43. d7+ Kd8 44. Rg5 1-0

Mark Hebden is the sole leader after round 5

The game between Robin van Kampen and Richard Vedder was over before we knew it. In this Ruy Lopez, Van Kampen answered Vedder’s Open Variation with a line that’s become popular recently. In fact in this line last year’s participant Merijn van Delft won very quickly as well against Ivo Timmermans, in Hoogeveen last October. It’s probably no coincidence that Van Delft and Van Kampen were staying in the same bungalow during that tournament!

Van Kampen – Vedder

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5 7. Bb3 d5 8. dxe5 Be6 9. c3 Bc5 10. Qd3 O-O 11. Nbd2 f5 12. exf6 Nxf6 13. a4 Rb8 14. axb5 axb5 15. Ra6 Bb6 16. Ng5

16 … Bf7N
Merijn van Delft, who played in the Batavia tournament last year, won another quick game from this position: 16… Ne5 17. Qg3 Qd6 18. Re1 Nfg4 19. Rxb6! Qxb6 20. Ndf3 Rfe8 21. Nxe6 1-0, Van Delft (2413)-Timmermans (2247), Hoogeveen 2011.
17. Nxf7 Rxf7 18. Nf3 Qd6 19. Be3

19 … Bxe3?!
19… Na5 20. Bc2 Nc4 21. Bxb6 cxb6 offers better chances.
20. fxe3! Qc5?
Necessary was 20… Re7.
21. Ng5 Rd7

22. Rxf6! gxf6 23. Ne4 Ne5 24. Nxc5 1-0

Against Keith Arkelll, David Klein survived a lost ending only to make one more big mistake later on.

Arkell – Klein

61… f5?
A ‘positional’ mistake. Now it will be much easier for White to attack the pawns. 61… Kc7 62. Nf4 g5 63. Nd5+ Kb7 64. Nxf6 Kxa7 65. Kg3 (65. Ng8 Kb6 66. Nxh6 Nc7 67. Kg3 Kc5 68. Kf3 Kd4 69. Nf5+ Ke5 70. Ke3 Nd5+) 65… Kb6 66. Kf3 Kc5 67. Ke4 Kd6 68. Ng8 Ke6 69. Nxh6 Nc7 70. Nf5 Kf6 and Black holds.
62. gxf5 gxf5 63. Kg3 Kc6 64. Kh4 Kb7 65. Kh5 Nc7 66. Kxh6 Kxa7 67. Kg6 Kb7 68. Nf4 Kc6 69. h4 Kd6 70. h5 Ke5 71. h6 Kxf4 72. h7 1-0

Like Achim Illner, Hugo ten Hertog only needs 1.5 out of 4 for a norm, thanks to the following victory.

Vandenbussche – Ten Hertog

22. a4?
Normally active play should be preferred, but here White needed to remain passive one more move: 22. Rf1.
22… Nxf2 23. Nxf2 Rxf2 24. a5 Kd6
The king will take care of it!
25. b4
25. a6 Kc7 26. Rh1 g5 27. Rh8 Kb6.
25… Rh2 26. Rf1 f2 27. Kb2 Kc7 28. Ra1 Kb7 29. a6+ Ka7 30. Bf1 g5

It’s clear that White cannot save this. The next move speeds up the loss.
31.c4?! Bxc4! 32. Kc3 Bxf1 33. Rxf1 g4 34. Kc4 g3 35. b5 cxb5+ 36. Kxb5 Rh1 37. Rxh1 g2 0-1

Manuel Bosboom’s dramatic tournament continued on Tuesday.

Illner – Bosboom

32… Bxb4?
Missing a simple double attack.
33. Qb5 Ne6 and Black resigned as well.

Wednesday was a rest day, but Achim Illner and Robin van Kampen played their round 3 game which they couldn’t play on Sunday. Apparently they needed some rest as well, because after twelve moves a draw was agreed. On Thursday at 14:00 hrs the 6th round starts in Cafe Batavia.

Update March 1, 14:18
Well, that was a nice little piece of sloppy journalism… At the start of round, 6 Van Kampen told us that he certainly wasn’t playing for a draw in his game against Illner. “But I was worse, and had less time on the clock in the final position.” We stand corrected!
