Two Chinese grandmasters, Wang Hao and Wang Yue, and Icelandic GM Hannes Stefansson finished tied for first place with 7 points each out of nine rounds in the Reykjavik Open completed last Tuesday.

Wang Hao was declared the tournament champion on tie break points. Hannes and Wang Yue share second place.

Fifteen-year-old Fabiano Caruana, the American-born national champion of Italy, who led the tournament at the halfway mark, finished tied for fourth with 6 points.

Former womens world champion Antoaneta Stefanova of Bulgaria had the highest score among women players in the event with 6 points.

Wang Yue finished with the most victories in the tournament with 6. Wang Yue was upset in the opening round by Bjorn Thorfinnsson, a federation master from Iceland who doubled as tournament organizer. Wang Yue then won his next five games in a row, drew in rounds seven and eight and scored a victory in the final round over Greek grandmaster Stelios Halkias to secure a share of first place and Wang Hao and Hannes played each other to a draw.

20...Nxa5 21.f4 Bg7 22.Qh4 Bb3 23.Rd4?

  • White is already a pawn down, and now proposes a dubious exchange sacrifice.
  • After 23.Raa1 a6 24.e5! (cutting off Black's counterplay) 24...Nc4 25.Bc5 Rfd8 26.Ne4 Nd2 27.Nf6+ Bxf6 28.exf6 White continues to enjoy a huge advantage in space.

23...Rad8?

  • When behind in space, one should exchange pieces. Cleary, Black should have taken the Rook.
  • If 23...Bxd4! 24.Bxd4 Qd6 25.Qf2 Rfd8 26.Bxa7 Nc4 then:
    • 27.Bxc4 Bxc4 28.Rc1 Qe6 leaves space even and Black is an exchange to the good.
    • 27.Rb1 Qd2 28.Bxc4 Bxc4 gives Black a small but sustainable edge in space in addition to the exchange.

24.e5!

  • There will be no second chance.

24...Rxd4 25.Bxd4 c5 26.Be3

  • Due to his dubious 23rd move, White's spatial advantage is much diminished, but Black's counteryplay has been slowed thanks to White's fine 24th move.

26...f6 27.Nb5

  • After 27.Ne4? fxe5 28.fxe5 Qxe5 29.Rxf8+ Bxf8 30.Nf6+ Kf7 the space count is even and Black is two pawns to the good.

27...Qd8

    • 31...Rxf6 32.Rd1 Bb3 33.Bc4+ Bxc4 34.Nxc4 Qc6 35.b3 gives White a small advantage in space, but not enough to compensate for his pawn minus.
    • 31...Qxd6 32.Rd1 Qb6 33.fxg7 restores a small advantage in space to White, who must lose a pawn in this position.

28.f5 fxe5

  • Black has won a second pawn.

29.Bg5 Qb6 30.f6

  • 30.fxg6 c4+ 31.Kh1 Rxf1+ 32.Bxf1 hxg6 33.Nc3 Qd4 gives Black a two-pawn advantage in which White does not dare accept the invitation to exchange Queens.

30...c4+ 31.Kh1 Qxb5

  • If 31...Bh8 32.Be3 then:
    • 32...Bxf6 33.Bxb6 Bxh4 34.Rxf8+ Kxf8 35.Bxa5 a6 36.Nd6 b5 leads to a likely draw.
    • If 32...Qxe3? 33.f7+! Kg7 34.Nc7 h5 35.Ne6+ then:

  • 33...Qd7 34.Bh6 Nc6 35.Bxc4+ Bxc4 36.Qxc4+ Qf7 37.Qc1 b5 gives Black the edge in space and an extra pawn.

34.Bd8

  • If 34.Bh6+ Kf7 35.Qd8 then:
    • 35...Bc2 36.Bg5 Ke6 37.Qf6+ Kd7 38.Qe7+ Kc6 39.Qf6+ Kd5 40.Qf7+ Kd6 41.Qe7+ Kc6 42.Qf6+ draws by repetition.
    • 35...Ba4 36.Bg5 Ke6 37.Qe7+ Kd5 38.Be2 Qe8 39.Bf3+ e4 40.Bxe4+ Kd4 is a likely draw.

34...Nc6??

  • When Topalov blunders, he really blunders.
  • If 34...Kg8 35.Qe7 Qd5 then:
    • 36.Bxa5 Qxa5 37.Qe8+ Kg7 38.Qe7+ then:
      • 38...Kh6 39.Qh4+ Kg7 40.Qe7+ draws by perpetual check.
      • 38...Kg8 39.Qe8+ Kg7 40.Qe7+ draws by perpetual check.
    • 36.Qe8+ Kg7 37.Bxa5 Qxa5 38.Qe7+ Kh6 39.Qh4+ Kg7 40.Qe7+ Kg8 41.Qe8+ draws by perpetual check.

14.d5

  • This sacrifice, quite commonplace nowadays, made its debut in the early years of the cold war.
  • The inagural game continued 14...Bxa1 15.Qxa1 f6 16.Kh1 Bd7 17.g4 b5 18.e5 Bc6 19.Be4 Bxd5 20.Rd1 Bxe4 21.Rxd8 Bxf3+ 22.Kg1 Raxd8 23.Nd4 Nc4 with spatial and material advantages for Black (Maicherczyck-Niephaus, West German Ch, Bad Pyrmont, 1949).
  • By the following year, it was being played at the highest levels of chess: 16.Bh6 Qb6+ 17.Nd4 Bd7 18.Rb1 Qc5 19.Rc1 Qb6 20.Bxf8 Rxf8 21.h4 gives the advantage in space to White (Bronstein-Boleslavsky, Candidates' Trmt, Budapest, 1950).

    • 25.Be3 Raxe4 26.Nxe4 Rxe4 27.Bxa7 Qxd5 28.Qxf6 gives Black an edge with his centralized pieces.

  • 33.Bc4 Be6 34.Bxe6 Rxe6 35.Rxa4 leaves White a pawn to the good.

33...Bf5

  • Even worse is 34.Bc4 when after 34...Rxc4 35.Rxc4 Be6 36.Rxa4 Kf7 37.Rg7+ Kxf6 38.Rxb7 White has an easy win.

34.Rxf5 Rexf5 35.Bxf5 Rxf5 36.Rxh6

  • White is a pawn to the good.

36...Rf2+ 37.Ka3 b5 38.f7 c5 39.Rb6 Rc2 40.Rxb5 Rxc3+ 41.Kxa4

  • White is now two pawns to the good.
  • To give an example of what can go wrong in a position like this. 41.Kb2? Rc4! 42.a3 Rxh4 43.Rxc5 Kxf7 equalizes for Black.

41...Rc4+ 42.Ka5 Rxh4 43.Rxc5 Kxf7

  • If White's last pawn were a Bishop's pawn or a royal pawn, Black might consider resigning here.

Position after 44...Kf7f6


45.Re3!

  • White's plan is:
    • Keep the Black King away from the pawn by confining it to the other side of the board with the Rook;
    • Advance the pawn along the a-file with the King in front of it (while Rooks belong behind a passed pawn in the endgame, Kings belong in front of it;
    • at the appropriate moment, use the Rook as a shield in the b-file to allow the King to make way for the pawn to promote.

  • If Black tries 48...Rf1 then after 49.Kb7 Kg5 50.Re5+ Kf6 51.Rb5! the pawn scores or Black surrenders the Rook stopping it.
  • 48...Ra1 49.Kb6 Rb1+ 50.Ka7 -- followed by 51.a6 doesn't help Black at all.

49.Ka7 Kf7 50.a6 Rb1 51.Ka8 Rb2 52.a7

29.Rxf5!!

  • White, who has one passed pawn, sacrifices the exchange (and he tosses in a pawn on the next move) in order to pass a second pawn. Both will reach the seventh rank.

29...exf5 30.e6

  • After 30.c7 Rc8 31.e6 fxe6 32.Be5 Rhg8 33.f4 34.Ke2 Kb6! Black will mobilize his queenside passers while White is tied to the defense of the pawn at c7.

Slav Queen's Gambit: Saduleto Opening

1.d4 d5 2.c4 c6 3.Nc3 dxc4 4.e4 b5 5.a4 e5

  • 5...b4 then:
    • 6.Na2 Nf6 7.e5 Nd5 8.Bxc4 e6 9.Nf3 Be7 10.Bd2 a5 then:
      • 11.Nc1 Nd7 12.Nb3 Bb7 13.0-0 0-0 14.Qe2 Qb6 gives White the advantage in space (Farago-Neelotpal, First Saturday, Budapest, 04.2005).
      • 11.0-0 Ba6 12.Qe2 Bxc4 13.Qxc4 Nb6 14.Qc2 Qd5 15.Nc1 N8d7 16.Nb3 c5 17.dxc5 Nxc5 18.Nxc5 Qxc5 19.Qe4 0-0 20.Rfc1 Qd5 21.Qxd5 Nxd5 22.Nd4 Rfc8 23.Nc6 Bd8 24.Nxd8 Rxd8 25.Kf1 is equal (Kostanjian-Peralta, Acropolis Op, Athens, 2006).
    • 6.Nce2 Nf6 7.Ng3 e6 8.Bxc4 a5 9.Nf3 Be7 10.0-0 Nbd7 11.Qe2 Bb7 12.Rd1 0-0 13.Be3 Nb6 14.Bd3 Qc7 15.Rdc1 Rfc8 gives White the early edge in space (Ward-Mannion, Op, Gibraltar, 2004).

6.dxe5 Qxd1+ 7.Nxd1

  • 7.Kxd1 b4 8.Nb1 Ba6 9.Nd2 c3 10.bxc3 bxc3 11.Nc4 c5 12.f4 Bb7 13.Ne2 c2+ 14.Kxc2 Bxe4+ 15.Kc3 Nc6 16.Ng3 Bd5 17.Nf5 Nd4 18.Nxd4 cxd4+ 19.Kxd4 Bc6 20.Ba3 Nh6 21.Bxf8 Rxf8 22.Nd6+ gives White an extra pawn and a huge advantage in space (Docx-Danner, Euro ChT, Saint Vincent, 2005).

7...Na6!?

  • 7...Nd7 8.axb5 cxb5 9.Nc3 Bb4 10.Bd2 Bxc3 11.Bxc3 Nc5 12.Bd4 Nb3 13.Rxa7 Rxa7 14.Bxa7 Ne7 15.Nf3 Bb7 16.Nd2 Nxd2 17.Kxd2 Bxe4 18.b3 Nc6 19.Bc5 Nxe5 20.bxc4 bxc4 21.Bd4 draw (Ippolito-Sarkar, Smartchess IT, New York, 2001).

8.Nf3

  • If 8.axb5 cxb5 9.Nc3 Bb4 10.Bd2 then:
    • 10...Nc7 11.Nd5 Bxd2+ 12.Kxd2 Kd7 13.Nf3 Bb7 14.Nd4 Nxd5 15.exd5 Bxd5 16.Nxb5 a5 is equal.

  • After 11.Bc3 a6 12.Rd1 0-0 13.Bd4 Bxd4 14.Rxd4 Ng6 15.Be2 Re8 Black threatens the pawn at e5.

11...a5 12.Rb1 cxb3 13.Rxb3 Bxe3 14.fxe3?

  • It's usually not a good idea to voluntarily triple a pawn; there's nothing about this position to make it an exception.
  • 14.Bxe3 bxa4 15.Rc3 a3 16.Kd2 a2 17.Bc4 Ng6 is unclear: Black is up by a pawn, but White may have enough extra space in compensation..

WHITE: Simona Limontaite
Position after 14.fe3:B


14...bxa4 15.Rb1

  • This second error compounds the first.
  • White gets more play from 15.Rc3 a3 16.Kd1 a2 17.Ra3 c5 18.Bc4, but it's still an uphill battle.

15...a3 16.Kf2 a2

  • Also good is 16...Be6 17.Nd4 a2 18.Ra1 0-0.

17.Ra1 0-0 18.Bc4 Be6 19.Rhc1

  • If 19.Bxe6 fxe6 20.Ke2 c5 21.Rhc1 then:
    • 21...Rfc8 22.Bc3 h6 23.Nd2 a4 24.Nc4 Rab8 Black has the upper hand with an extra pawn, better pawn structure and passers running wild on the queenside, but Black could try for some counterplay on the d-file.
    • 21...Rac8 22.Rc4 Rc6 23.Bxb4 cxb4 24.Rxc6 Nxc6 25.Rxa2 b3 followed by 25...Rb8 Black wins.

19...Bxc4 20.Rxc4 c5 21.Ke2 Rac8 22.Ne1

  • After 22.Bxb4 cxb4 23.Rxc8 Rxc8 24.Rxa2 Ra8 25.Kd3 a4 Black's pawns continue to march.

22...Rc6!

  • This is in preparation to recapture the Rook at c6. See next note.

23.Nd3 Rd8 24.Nc1

  • After 24.Nf4 h6 25.Bxb4 cxb4 26.Rxc6 Nxc6! (this is made possible by 22...Rc6; the Knight is in position to protect both passers and also attacks the lead pawn in White's triplet) 27.Rxa2 Rb8 28.Ra1 b3 Black wins.

24...Rh6 25.h3

  • White could put up a more stubborn resistance with 25.Rxc5 Rxh2 26.Bxb4 axb4 27.Kf3 Rh6 28.Rxa2 Kf8 29.Nb3 Re8.

25...Rg6 26.g4 Rh6 27.Rxc5 Rxh3 28.Be1 Rh1 29.Nxa2 Rh2+ 0-1

  • After 30.Kf3 Rxa2 31.Rxa2 Nxa2 32.Rxa5 Nc1 Black has an extra piece.
  • Ms. Limontaite resigns.

  • 40.Kh2 Bb7 41.Bf3 Rb6 42.Kh3 Bc6 43.Kg4 Kf8 nobody is going anywhere.

    • 44.Kh2 Bb7 45.Rc7 Rb6 46.f5 gxf5 47.gxf5 Rb3 is equal and lifeless.
