After the round I visited the Hungarian High School Team Ch which was nearby. I was promised some pictures for the blog by one the the coaches-GM Joseph Horvath who was particularly happy as his team was in the lead. The event will last a couple more days.

Here is my game from this evening(Monday Oct 29).

Vemes,G (2007) – Yip,M (2087)
Sicilian Kan[B42]

White tried an unsound queen sacrifice early in the opening and is now being pushed back. Black has Q+P for 3 minors pieces and has consolidated nicely.

Trends in the Sicilian Kan 5.c4 Bind(B41)

Here is an interesting game in the topical Maroczy Bind featuring Chinese GM Ni Hua.

‘Ni Hua (born May 31, 1983 in Shanghai)[1] is one of China’s top chess grandmasters and is the national team captain. In 2003, he became China’s 15th Grandmaster at the age of 19.

On April 2008, Ni Hua and Bu Xiangzhi both became the second and third Chinese players to pass the 2700 Elo rating line, after Wang Yue. He also played 4th board at the World Team Chess Championship in January 3–14, 2010..-Wikipedia

TCh-CHN 2012 Hangzhou CHN (11), 22.09.2012

Critical Position 1(28…Kh7)
All white’s pieces are pointed at the queenside and poised for action. c5 is the theatic break. Does this need more preparation(with say Nb3)? or can c5 be played right away?

White to play

Critical Position 2(40..Bd7)
White has made some progress. Na5 ties up the queenside pawns and the passed d-pawn is in a menacing position. But what is the next step?

Vintage Portisch on the Sicilian(1962)

Here is a model dark square maneuvering game by Portisch from Stockholm 1962, in the Sicilian Kan/Scheveningen.

Typical middlegame themes include

  • Good knight vs bad bishop, arranging pawns to compliment one’s own bishop
  • Knight regrouping(..Nb8-c6-d4)
  • Correct exchanging(..BxNd5)
  • Exchange sacrifice breakthrough
  • Attak on the king

13…c5 14.b3 Rd8 15.Nc3 Bb7 16.f4 Nd7 17.Qd2 Rbc8 18.Nd1  
After this leisurely retreat black takes over on the dark squares.[Yip][18.Rad1= [Yip]]

 

18…Bf6
Starting to battle for the central dark squares.[Yip]

 

19.Rc1 Diagram 1

 
 

[19.Nc3 Going back to c3 and admitting that Nd1 was unproductive is a better.[Yip] 19…Nb8 20.Rad1 Nc6 21.f5 Re8 22.fxe6 fxe6 23.Ne2 Rcd8= I prefer black with as there is the dynamic ..d5 break to play for.[Yip]]

 

19…Nb8!
Heading to d4 eventually.[Yip]

 

20.Nf2 Nc6 21.Ng4 Bd4 22.f5 Bxe3+ 23.Qxe3 f6!   Continuing to battle for the dark squares. Now the secondary idea is the make white’s light bishop a spectator.[Yip]

 

24.Qf2?
Now white will suffer on the dark squares.[Yip] [24.fxe6!? Keeps the game close.[Yip] 24…Nd4 (24…Re8 25.e5 Nxe5 26.Nxe5 dxe5 27.Bd5= [Yip]) 25.Qd2 Nxe6 26.Ne3 Ra8 27.Rc3 a5 28.Rd3 Ng5 29.Rd1 Nf7= [Yip]]

 

24…e5!   The pawn structure is transformed into a dark square wall to complement Bb7 and lock onto d4 for the knight.[Yip]

 

25.Ne3 Nd4   Now Nd4 is the dominant minor piece.[Yip]

 

26.g4 a5   Playing for the queenside.[Yip]

 

27.Rb1 Ra8   Now the line opening ..a4 break is in the air.[Yip]

 

28.h4 Qe7 29.Qd2 h6!
Black must take defensive measures against the threatened g5 break.[Yip]

30.Rb2 Kf8   A nice defensive king walk in light of the threatened g5 break.[Yip]

 

31.Kh2 Bc6 32.Nd5 Bxd5!
Now the minor piece battle is won for black as the good N easily dominates the bad B.[Yip]

 

33.cxd5 Rdb8
Full attention is turned to the queenside. Black must open lines as the well placed Nd4 cannot win the game without additional entry points into white’s position.[Yip]

 

34.Reb1 Rb7 35.a4   A drastic measure to prevent the …a4 break but now the future of the bishop is even dimmer.[Yip]

 

35…Rab8 36.Bf1 Rb4 37.Bc4
White goes over to a completely passive defence and now the search is on for black for a way to break into white’s position.[Yip]

48…Rxc4!
Finally a way to infiltrate appears.[Yip]

 

49.Qxc4 Rb4 50.Qc3 Qa6
The knight is not inferior to any rook on the secure d4 outpost.[Yip]

 

51.Kf2 c4! [Yip] 52.bxc4 Rxc4 53.Qa3?
Guarding the a-pawn allows black to infiltrate on the c-file.[Yip] [53.Qd2 Is a tougher defence.[Yip] 53…Qc8 54.Re1 Qc5 55.Kg2 Rxa4 56.Rc1 (56.Re3 Rc4³ [Yip]) 56…Rc4 57.Rxc4 Qxc4 58.g5! White has to try an open up the kingside for counterplay.[Yip] 58…hxg5 59.h6 gxh6 60.Qxa5= The game remains competitive.[Yip]]

 

53…Qc8!–+   Now white cannot challenge the c-file.[Yip]

 

54.Rd2 Rc3 55.Qb2 Qc4 56.Kg2 Nb3
[56…Nf3! Going to the kingside is stronger.[Yip] 57.Rf2 Nh4+ 58.Kh2 Qd3–+ [Yip]]

Developments in the Sicilian Kan 5.Nc3 Qc7 6.Be2

Here is an interesting game from Delchev.

Horvath,Ta(2398) – Delchev,A (2598) [B43]
6th Varna Open Varna BUL (7.4), 18.07.2012
Black has typical counterplay well under way. Both bishops are fianchettoed and the e5 pawn is a permanent target. The queenside pawns are poised to advance and black controls the d-file. But how to proceed?

Sicilian Kan 5.Nc3 Qc7 6.Bd3 Nf6-April 2012

Here is an interesting game by Akopian.

14th Dubai Open 2012 Dubai UAE (2.3), 16.04.2012

Position 1
White gambited a pawn for kingside chances and gets nowhere. Slowly black consolidates taking a strangle hold on the dark squares leaving white no chance.

White to play
Black just played 28..Rd6 preparing to double rooks on the d-file.
