The JR Chess Report (March 6): Ivan Sokolov wins Reykjavik Open on tiebreaks
Ivan Sokolov wins Reykjavik Open on tiebreaks



Bosnian grandmaster Ivan Sokolov won the Reykjavik oven on tiebreaks Wednesday after defeating American IM Alex Lenderman.

Sokolov's chances appeared slim to none after losing in Tuesday's eighth round to former world junior champion Abhijeet Gupta of India, leaving Sokolov a half-point behind Gupta and Icelandic GM Hannes Stefansson, who were then paired to play each other on Wednesday.

However, Gupta and Stefansson unwisely agreed to a draw after only nine moves in the final round, figuring that Sokolov, who was outplayed by Lenderman in the opening, couldn't win.

Sokolov, Gupta, Stefansson and Ukrainian GM Yuriy Kuzubov, who also had to win his last round game Lithuanian GM Aloyzas Kveinys to join the log jam at the top, each finished with 7 points out of nine rounds.

Indian IM Dronavalli Harika, who won the world girls' championship at the same time that her compatriot Gupta won the junior title in 2008, had the top score among the participating ladies with 6 points.


11th European Championships begin in Rijeka



The eleventh annual European Individual Chess Championships began today in the city of Rijeka in the former Yugoslav republic of Croatia.

There were few outright upsets in the first round of the general competition, although Zoltan Almasi, Alexander Motylev and defending champion Evgeny Tomashevsky, all rated over 2700, were each held to draws by opponents rated under 2500. The biggest Goliath who fell to a David occured on board 25, where Russian IM Artem Smirnov (2435) took down his venerable compatriot, grandmaster Evgeny Najer (2665).

In the women's competition, former world women's champiopn Antoaneta Stefanova of Bulgaria (2555), playing on the top board, was held to a draw by Georgian WIM Meri Arabidze (2292) and another Georgian, WGM Sopiko Guramishvili (2266) drew with this year's winner of the Gibraltar Masters' ladies' prize, Natalia Zhukova of Ukraine (2492). Otherwise, ther were no ther surprised and it was a good day for players named Kosintseva (Nadezhda and defending tournament champion Tatiana) and Muzychuk (Anna and Mariya), who all won their respective games.

Both groups will play eleven rounds, concluding Friday, March 19 with Saturday, March 13, scheduled as a rest day. Action is broadcast live on the official tournament website, with rounds beginning at 3:30 pm local time, which is a fairly reasonable 6:30 am PST.

3. I. Sokolov - Lenderman, Round 9
It appeared that Bosnian-turned=Dutch-turned-Bosnian-again GM Ivan Sokolov was knocked out of the running by his loss to formner world junior champion Abhijeet Gupta the day before the last round.

In this game, US international master Alex Lenderman, a young man with a bright future, outplayed Sokolov in the opening. It looked like Sokolov was fighting for a draw in a game he had to win.

In neither case is it over until the fat lady sings.

International Open, Round 9
Reykjavik, 3 March 2010

Slav Queen's Gambit: Chameleon Defense


1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 a6 5.a4

5...e6 6.g3 Bb4

  • With White committed to developing his King's Bishop on the flank, the most frequent move here is the drawish 6...dxc4.
  • 6...dxc4 7.Bg2 c5 then:
    • If 8.dxc5 Qxd1+ 9.Nxd1 then:

WHITE: Ivan Sokolov
Position after 13.e2e4


13...c5!

  • Black attacks the now-weakened e4.
  • 13...dxe4!? 14.Nxe4! Nf6 15.Rfd1 Re8 16.Nc5 gives White the initiative.

14.exd5 cxd4 15.Ne4!?

  • White seems oblivious to the danger facing him.
  • 15.Ne2 e5 16.d6 Bxg2 17.dxe7 Qxe7 18.Kxg2 exf4 maintains Black's initiative.

15...e5!

  • Black has the initiative.

16.Bd2 f5 17.c5

  • 17.d6 fxe4 18.dxe7 Qxe7 19.Bb4 Nc5 leaves Black a pawn up.

17...fxe4!?

  • While this move looks reasonable, it quashes Black's initiative.

    • 18.Ng5! Qb8 19.d6+ Kh8 gives Black an extra pawn.
    • 18.Nxc5? Nxc5 19.Qa2 Rf7 20.b4 Ne4 21.d6 Qxd6 leaves Black with two extra pawns.

WHITE: Ivan Sokolov
Position after 17...fe4:N


18.c6!

  • It is doubtful that Black overlooked this move; since he loses neither piece that is "forked", it is more likely that he simply underestimated its strength.

18...Nc5 19.Qa2 Bc8 20.b4 Kh8!?

  • Black unnecessarily consents to equality.
  • If 20...Nd3! then 21.d6+ Kh8 22.dxe7 Qxe7 23.Bxe4 then:
    • If 23...Nxb4! 24.Qb1 a5 25.Rc1 Bg4 then:

      • 26.Ra3 Be6 27.Rf3 Rxf3 28.Bxf3 Rc8 29.Bg2 Kg8 gives Black greater activity.
    • If 23...Bf5!? 24.Bxf5 Rxf5 25.f3! Qf8 26.Qc4 then:
      • 26...Rxf3 27.Rxf3 Qxf3 28.Rf1 Nb2 29.Qc2 wins the Knight.
      • 26...Nb2 27.Qb3 wins the Knight.

21.bxc5 Bxc5 22.Bxe4 Bh3!

  • Black gets the upper hand.
  • If 22...Qf6!? then 23.f4! (Blocking Black's access to White's kingside) 23...Bh3 24.Rfe1 Rad8 25.Rac1 is once again equal.

23.a5?!

  • White invites Black to take the exchange. It isn't an entirely sound sacrifice.
  • 23.Rfc1 Qf6 24.Be1 Bf5 25.Bxf5 Qxf5 gives Black the better game; White's passers are too weak to maintain.

23...d3?

  • The passer imprudently moves beyond its sphere of protection.
  • 23...Bxf1! 24.Rxf1 Qd6 25.f4 b5 26.Kg2 Rad8 gives Black more freedom; in this position, White is fighting for a draw..

33.Bb7 Rxc7 34.Qxc7 g6

11...Nbd5

  • The text move was introduced into master play in the game Harikrishna-Predojevic (see note to White's 15th move).
  • If 11...Bg7 then:
    • If 12.Qb3 0-0 13.0-0 Nfd7 then:
      • 14.f4 Qc7 15.Bd2 c5 16.Nb5 gives White the advantage in space (Cramling-Pähtz, ITW, St. Petersburg, 2009).
      • 14.Ne2 Qc7 15.e4 Nc8 16.f3 Rd8 gives White the advantage in space, but Black has no exploitable weaknesses (Jobava-Shirov, Russian ChT, Sochi, 2007).
    • 12.0-0 0-0 13.Qe2 Nfd5 14.Rd1 Nb4 15.b3 N6d5 16.Bb2 Nxd3 17.Qxd3 Nxc3 18.Bxc3 Qd5 19.Qc4 Rfd8 20.Rac1 f5 is equal (Adianto-Bu Xiangzhi, Op, Doha, 2006).

12.Qb3

  • 12.0-0 Bg7 13.Bd2 0-0 14.Qb3 Qb6 15.Qxb6 Nxb6 16.b3 Rfd8 is equal (Ivanisevic-Pavlovic, Zürich Chess Club Bicentennial, Zürich, 2009).

12...Qb6 13.Qxb6 Nxb6 14.Ke2 Bg7 15.b3

  • 15.Rd1 0-0 16.Bd2 Nfd7 17.b3 e5 18.dxe5 Nxe5 19.Nxe5 Bxe5 20.Rac1 is equal (Harikrishna-Predojevic, IT, Sarajevo, 2009).

15...0-0 16.Bd2 Nbd5!?

  • 16...Nfd7 17.Rac1 e6 18.Ne4 Ra7 19.Rhd1 gives White the advantage in space (Cramling-Blumquist, Swedish Ch, Kungsør, 2009).

17.Nxd5 Nxd5 18.Rac1

  • White has the advantage in space.

18...Ra7

  • 18...Rfc8 19.Rc5 b6 20.Rc4 e6 21.Rhc1 Ne7 22.Ne5 gives White the initiative against the c-pawn.

19.f3 Nb6 20.Rhd1 Nd7 21.Be1 Re8 22.Nc5 Nf8

  • 22...Nf6 23.e4 h6 24.Ke3 e6 25.Nd3 gives White a solid center.

23.Bg3 Rc8 24.Rc4 Ne6!?

  • Black gives White an opportunity to spoil his pawn structure.
  • If 24...h6 then White remains better after 25.Rdc1 f5 26.Rd1 Kf7 27.e4 b6 28.Nd3, but Black's queenside majority still gives him hopes of gaining counterplay.

WHITE: Znosko-Barovsky
Position after 24...Nf8e6


25.Be1!?

  • Rather than this time consuming plan of redeloying the Bishop, White could simply destroy Black's central pawn structure.
  • If 25.Nxe6! fxe6 26.Be5 then:
    • 26...Rd8 27.Bxg7 Kxg7 28.h4 e5 29.dxe5 Rxd1 30.Kxd1 gives White an extra pawn and the more active Rook.
    • If 26...Bf6 then after 27.e4 h6 28.f4 Kf7 29.g4 b6 30.h4 White is pushig Black off the board.

25...Rca8!?

  • Black could have better exploited White's inaccuracy.
  • If 25...Nc7 then White remains better after 26.Rc2 b6 27.Nd3 Ne6 28.d5 Nd8 29.e4, but Black has potential counterplay on the queenside after 29...c5.

26.d5!?

  • White intends to break through in the center.
  • Once again, 26.Nxe6, spoiling Black's center, is the best idea.

26...cxd5 27.Rxd5 Nf8 28.Nd3 Bf6!?

  • This waiting move does nothing for Black.
  • 28...b6 makes Black's second rank move navigable for the Rook, but after 29.Rc6 Rb7 30.e4 Ne6 31.Bf2 Rab8 Black still has the active game.

  • This move loses the game for good (if Black's 28th move didn't already).
  • Better is 30...Nd7 31.e5 Bg7 32.f4 Rb7 33.Rc6 Rab8 34.g4 when Black holds on to the b-pawn and White switches to an attack on the kingside.

31.Rb5 Nd7

  • If 31...Ne6 32.Rxb6 then:

      • 38.Rf7 Kxe4 39.Rxf6 c5 40.Re6+ Kd5 41.Rb6 Kd4 gives Black better chances, but that is contingent on maintaining his last pawn.
    • If 34...Rf3 35.Re6 then:
      • 35...Rxb3 36.Rxc6 Kxe4 37.Rxf6 Ke5 38.Rf7 Rb2 is a probable draw.
    • 35...Ng3+ 36.Nxg3 Rxg3 37.Rxf6+ Kxe4 38.Rxc6 Rxb3 draws.

34...Kf3 35.Rh6 Kxe4 36.Nd6+

  • 36.Rxf6 Rxf5 37.Rxc6 Rb5 38.Kg2 Nf4+ 39.Kf2 Rxb3 gives Black an obvious advantage, but it's not an easy game to win.

36...Kd4 37.Rh4+ Rf4

  • Black's winning chances are a little bit better after 37...Ke3 38.Rh3+ Kf4 39.Rh6 Ke5 40.Nf7+ Kd5.

38.Rh2 Rf1+ 39.Kg2 Rb1 40.Rh4+ Kd5 41.Ne8

  • 41.Nc8 Rb2 42.Nb6+ Ke6 43.Na4 Nf4+! 44.Kg3 Rxb3+ gives Black two extra pawns.

41...f5 42.Kf2 Nc3 43.Rh5?

  • Black must now lose his last pawn.
  • 43.Ng7 Ne4+ 44.Kg2 Rb2+ 45.Kg1 Ng3 46.b4 saves the pawn, but not the game.

  • The pawn is won.

    • If 53...Kh4!? then after 54.Ne5 Nd2+ 55.Ke1 f3 56.Rf7 Kg3 57.Nd3 Black may have to work harder to bring the game home; the f-pawn is stalled for the moment.

52...f4 53.Ne5 Nd2+

  • Also good is 53...c5 when after 54.Ra8 Nd2+ 55.Ke1 c4 56.Rg8+ Kh4 Black remains two pawns to the good.

  • White has the advantage in space, but neither side is yet fully developed.

9...Nc5 10.Nd2 Be6 11.0-0 Be7 12.a5 d5!?

  • This is indeed a provocative move. White is a little better developed, so the move can hardly be considered sound. Of course, Grandmaster Areshchenko knows this very well.

  • However, Black is determined to provoke White and doesn't play the objectively best move, either.
  • 14...Bxf3 15.Nxf3 Ncd7 16.Bg5 0-0 17.Qe2 Bb4 remains equal.

15.Nde4!

  • White seizes the initiatiative.
  • 15.Re1 0-0 16.Qe2 Rfd8 17.Nb3 Nxb3 18.cxb3 Rd7 remains equal.

15...Ncxe4 16.Nxe4 Nxe4 17.Bxe4 f5

  • If 17...Rc8 then after 18.Bb6 Qb8 19.Re1 0-0 20.c3 f5 21.Bd5 White continues to enjoy the initiative.

18.Bb6 Qc8 19.Bd5 Qd7

  • White initiative is just about spent, but worth the effort. He has more space, more activitity for his Bishops and is ready to put his heavy pieces on open files in the center.
  • 19...0-0 20.c4 e4 21.Re1 Bb4 22.Re3 Rf7 23.Qd4 won't stop White from carrying out his plans.

20.Re1

  • White's general plan is to place his heavy pieces in the center. There are many ways to go about this.
  • 20.Qh5+ g6 21.Bxe6 Qxe6 22.Qe2 Rc8 23.Rad1 is just as good as the text that follows.

20...Bf6 21.Bxe6 Qxe6 22.Qh5+

  • White seeks to weaken Black's kingside dark squares by provoking 22...g6. However, since Black has a dark-bound Bishop, this is of little consequence.
  • An alternate plan is to strengthen White's hold on the central dark squares by 22.c3, but after 22...0-0 23.Qe2 Rac8 24.Rad1 e4 25.Qd2 White's grip on the light squares looks shakey.

22...g6 23.Qh6

  • White has succeeded in his plan, but his own light square weakness makes it easy for Black to equalize.
  • If 23.Qe2 e4 24.c3 0-0 25.Rad1 then:
    • 25...Rac8 26.Qe3 Qc6 27.Rd2 Bd8 28.Red1 Bxb6 29.axb6 is equal.
    • 25...Rf7 26.Rd2 Bg5 27.Rd4 Bf6 is equal.

  • Black's inability to castle does not keep him from effectively connecting his Rooks.
  • 23...Qc4!? 24.Rac1! Qb4 25.b3 e4 26.Rcd1 Rc8 27.Re2 gives White advantage in space and makes a target of Black's wayward Queen.

  • Black omits 24...f4, cutting of the White Queen's escape.
  • 24...f4! 25.Rd3 Bg7 26.Qh3 Qxh3 27.Rxh3 is equal.

25.Qh3!

  • White finds the strongest move, giving him some say on what happens on the light square.
  • Also good, but not quite as good, is 25.Qe3 Rac8 26.Re2 e4 27.c3 Rhf8 28.Red2.

25...Rhe8

  • White has the better game. Black's options are limited.
  • 25...f4?? loses immediately to 26.Rd7+!!.

  • Although the game is so equal as to appear calm, there are many eddies and riptides running under the surface that can drag down a careless player carry him out to sea.
  • If 36...Bh6 (overprotecting the pawn at d2) then 37.h3 Re4 38.Bc3 Qd6 remains equal.

      • If 11...cxd5 12.cxd5 e5 13.Rb1 d6 14.e4 Bd7 15.h3 gives White the advantage in space (M. Gurevich-Stocek, Euro Ch, Antalya, 2004).
      • 11...Qb6 12.Rb1 exd5 13.cxd5 Nce4 14.Bb2 d6 15.Rc1 gives White the advantage in space (Vyzmanavin-Salov, Young Soviet Masters, Yurmala, 1983).

    • 14...cxd5!? 15.e5 Nfe4 16.Ngxe4 dxe4 17.Nxb5 Qb6 18.Nd6 is equal.

10.Bc2

  • White has the advantage in space, but development is not yet complete.

10...Nc5 11.Rb1!?

  • The text is a curious move that indicates a plan of queenside expansion; see also the note to White's ninth move.
  • Fritz suggests a more conventional plan in the center such as 11.0-0 exd5 12.cxd5 c6 13.Qf3 Bb7 14.dxc6 Bxc6 with equality.

11...Nb7!?

  • There are more active ways to deal the the threat of 12.b4.
  • 11...a4 12.dxe6 dxe6 13.0-0 e5 14.Nh5 Bb7 remains equal.

12.0-0 Nd6

  • The Knight remains at this post for some time, hindering Black's ability to effectively fight in the center.

13.b3 Ba6 14.a4

  • This is a very interesting move that prevents Black from freeing his game with 14...b5.
  • White has a good game in any case, for if 14.dxe6 dxe6 15.e4 then:
    • 15...Nd7 16.Re1 e5 17.Qh5 gives White the advantage in space.
    • 15...e5 16.Qf3 Qd7 17.Rd1 Qc6 18.Bb2 gives White the advantage in space.

14...exd5

  • The game is equal.

Position after 18...Bb7c6


19.h4!

  • This is a fine defensive move. Black is focusing on the g2 point, but to make that effective he needs to drive away the White Knight. With the text move, ...h7-h5-h3 is ruled out.

19...Qh6

  • 19...Qe7 20.Rfd1 Bb7 21.Qg4 Qe6 22.Qxe6 fxe6 23.Be5 gives White the advantage in space.

20.Rbd1 Re6 21.Qg4 Rae8!?

  • Black gains nothing by doubling the Rooks on the e-file as there is no good square for the lead Rook to land beyond where it is.
  • If 21...Rd8 (overprotecting the d-pawn) 22.h5 then:
    • 22...f6 23.Bc1 Qg5 24.Qxg5 fxg5 25.Nf5 gives White more space and weakens Black's kingside.
    • 22...g6 23.Nf5 Qxh5 24.Qxh5 gxh5 runs the same theme as the text.

22.h5 g6!?

  • Black voluntarily spoils his pawn structure.

23...Qxh5 24.Qxh5 gxh5

  • Black has an extra pawn, but his kingside is so weak that it doesn't count for anything.

25.Nd4 Rh6

  • Black brings his Rook to the queenside to protect the weak pawns.

26.Nxc6 dxc6 27.g3!?

  • White weakens his kingside.
  • 27.Kh2 Bg7 28.Ba3 c5 29.Rd2 h4 30.Rfd1 Be5+ maintains the advantage for White.

27...Bg7!

  • Black should break up White's pawns where he can.
  • 29...h4 30.Rxh4 Rxh4 31.gxh4 h5 32.Rd1 Kf6 leaves Black's pawn weaknesses less exploitable than before and Black's King is active.

35...hxg4+ 36.Kxg4

  • Suddenly, White is two connected passers to the good.

36...Rd3 37.Rh1 Kg7 38.e4 Rxb3

11. Anand - Kempinski, Round 11
Edited on Sun Mar-07-10 12:23 AM by Jack Rabbit
Vishy Anand, the reigning world champion, broke his training for his April title match against Veselin Topalov to play top board for Baden Baden, February 27-28. Vishy scored a point and a half in the two rounds. His win over the Polish GM Kempinski was very convincing.

Vishy Anand (Baden Baden) - Robert Kempinski (Hamburg)
Bundesliga 0910, Round 11/Board 1
Heidelberg, 28 February 2010

Open Sicilian Game: Najdorf-Scheveningen Defense


1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 e6 7.0-0 Be7 8.a4 Nc6 9.Be3 0-0 10.f4 Qc7 11.Kh1 Re8 12.Bf3

  • For moves up to here, see , IT, Linares, 2009.

12...Nd7 13.Qe1!?

  • If 13.Qe2 Rb8 14.Qf2 then:
    • 14...Bf8!? 15.Rad1 Nb4 16.Bg4 b6 gives White a slight advantage in space (Mkrtchian-Javakhashvili, Euro Club Cup W, Saint Vincent, 2005).
    • 14...Bf6 15.Rad1 Nxd4 16.Bxd4 b6 17.Qd2 remains equal.

13...Bf8!?

  • It appears better to activate rather than retreat the Bishop. Should the f7 point become a target for White's pieces (as it does), Black could return the Rook to f8 much more easily.
  • 13...Bf6 14.Qd2 Nxd4 15.Bxd4 Bxd4 16.Qxd4 e5 17.Qd2 remains equal.

14.Qf2 Rb8 15.Rad1

  • If 15.Nde2 b5 16.axb5 axb5 17.f5 then:
    • 17...Nde5 18.fxe6 fxe6 19.Nd4 Nxd4 20.Bxd4 Nxf3 21.Qxf3 is equal.
    • 17...b4!? 18.fxe6 fxe6 19.Bh5 Rd8 20.Na4 Nf6 21.Bf3 is equal.

15...Nxd4 16.Bxd4 b6!?

  • This may be a bit timid.
  • 16...b5 17.axb5 axb5 18.e5 b4 19.Ne4 d5 20.Ng3 remains equal.

17.e5!?

  • White's strenght is on the kingside and he would have done better by advancing there.
  • If 17.f5! then:
    • If 17...Ne5 18.fxe6 Bxe6 19.Be2 then:
      • 19...Qb7 20.Nd5 Bxd5 21.exd5 b5 22.axb5 axb5 23.Bf3 gives White more space and better pawn structure.
      • If 19...a5?! 20.Bb5 then:
        • 20...Re7 21.Nd5 Bxd5 22.exd5 g6 23.Rde1 gives White the advantage in space, better pawn structure and command of a strong square at c6.
        • 20...Rec8 21.Ba6 Re8 22.Nd5 Bxd5 23.exd5 gives White more space and better pawn structure.
    • 17...exf5!? 18.exf5 Bb7 19.f6! g6 20.Nd5 gives White the advantage in space.

17...dxe5?!

  • Black opens the center for White's heavy pieces. This is a very bad idea.
  • 17...d5 18.f5 Nxe5 19.fxe6 Nxf3 20.exf7+ Qxf7 21.Qg3 Bf5 22.Qxf3 remains equal.

18.fxe5 Bc5

  • This move comes too late to save Black's King's position.
  • If 18...Nxe5 19.Bh5 then:
    • 19...Ng6 20.Bxg6 hxg6 21.Be5 Qxe5 22.Qxf7+ Kh8 23.Qxe8 wins for White.
    • 19...Nf3 drops a piece to 20.Qxf3 Re7 21.Qe2 f6 22.Bg4 Re8 23.Bf5.

WHITE: Vishy Anand
Position after 18...Bf8c5


19.Bh5!

  • The inadequately defended f7 point has now become a target for White.
  • 19.Bxc5!? bxc5 20.Bc6 Re7 21.Bxd7 Bxd7 22.Rd6 is equal.

19...Rf8 20.Bxf7+ Kh8 21.Ne4 Nxe5?

  • This allows White a quick win.
  • 21...Bxd4 22.Qxd4 Qxe5 23.Qb4 Nc5 24.Nd6 Bd7 25.Rfe1 gives White the advantage in space, but Black still has the ability to fight back.

22.Nxc5!

  • Good, but even better is 22.Bxc5! bxc5 23.Qxc5 Qxc5 24.Nxc5 Rxb2 25.Bxe6 when White wins a pawn.

22...bxc5 23.Bxe5

  • White has a quicker win after.23.Bc3 Ng6 24.Qd2 Bb7 25.Bxg6 hxg6 26.Qg5.

23...Qxe5 24.Bg6!

  • This is what Vishy wanted. The White Queen is perfectly safe, of course, as is the Bishop.

24...Rg8

  • Black now loses quickly.
  • 24...Qf6 25.Qg1 Qe7 26.Rxf8+ Qxf8 27.Qxc5!! Bb7 28.Qh5 leaves White dominating the board.

12. Update (Tuesday): Jobava, Efimenko and Monika Socko lead in Rijeka
Edited on Tue Mar-09-10 09:43 PM by Jack Rabbit


Only three players -- two men and one woman -- have perfect scores after four rounds. in the 11th European Chess Championships being held this week and next in the Croatian port city of Rijeka, once called Fiume when the city was part of Italy or Hungary.

In the General Group, Baadur Jobava of Georgia and Ukraine's Zhar Efimenko are tied for first place with 4 points apiece followed by 15 chess maters at 3½ points each, including Bosnina grandmaster Ivan Sokolov, just off his championship performance last week in the Reykjavik Open.

In today's action, Jobava, playing Black was the beneficiary of a blunder by Polish grandmaster Michal Kransenkow on the 33rd move of their game.

WHITE: Michal Krasenkow
Position after 32...Re4e3:B


The game is equal after 33.Qf1 Bf6 34.R7xd5 Qe8 35.Rd7, when White has a Rook for a minor piece and a pawn for which Black is compensated with his command of the e-file. However, White instead played 33.Qg2?? allowing Black to retort with the tactical shot 33...Bd4!! to which White replied 34.Rxd4 (otherwise White remains down a piece) 34...Re1+ 35.Qf1 Nd3! and Krasenkow resigned. If White plays 36.Qxe1, then Black delivers mate immediately with 36...Qg2; otherwise, if 36.Rd8+ Kg7 then the only way play has to stop Black from executing the threat of mate (37...Rxf1#) after running out of checks is 37.Rd1, but then 37...Rxf1+ 38.Rxf1 Qxe8 leaves Black with a material advantage of the Queen, a Knight and a pawn for a mere Rook.

Efimenko defeated the number one German grandmaster, Arkadij Naiditsch, in 42 moves after completely outplaying his opponent in the middle game. That game will one of those featured this coming weekend.

In the women's group, Polish grandmaster Monika Socko defeated Serbian WGM Irina Chelushkina, a journeyman chess master rated 2319 who played the role of upstart by winning her first three games. Mrs. Socko, who is the reigning champion of the Arctic Chess Challenge, making her the only woman who is currently champion of strong mixed-gender international open tournament, is the last participant in the women's group to brandish a perfect score. Tomorrow, Mrs. Socko plays Anna Muzychuk, one of seven ladies ties for second on 3½ points. Defending European women's champion Tatiana Kosintseva of Russia, another of those tied for second, will play IM and many times former French women's champion Almira Skripchenko, also on 3½ points, in what promises to be an interesting match up tomorrow on board 2.
