    • 22.Rb2?! e4 23.b5 Nc7 24.h4 Qh6 25.Bxf7+ Rxf7 gives Black the advantage in space and the more open Bishop.

21...Qg5 22.b5

  • 22.Qe2?! e4 23.Na2 Be5 24.Re3 Rae8 25.b5 gives Black the advantage in space.

22...Nc7 23.Bxf7+

23...Rxf7 24.Ne2 Rg7

  • If 24...Qg4 then retains the advantage after 25.Qc2 Rg7 26.Nxf4 exf4 27.a4 with fewer pawn weaknesses and an embryonic throne in Black's side in a passed h-pawn.

  • If 25.Qc2 Bd2 26.Rg3 Qh6 27.Rxg7+ Kxg7 then:
    • 28.Nf3 Bg5 29.Ng3 Rf8 30.Nxg5 Qxg5 31.Qc3 is equal.]

    • 29.Bxc7?! Qxc7 30.Qb1 Bxb3 31.Qxb3 Rd8 gives Black the exchange.

27.Be3?!

  • 27.Bb4! a6 28.a4 f4 29.a5 bxa5 30.Bxa5 doesn't give Black nearly enough compensation for his pawn.

27...f4 28.Bc1 Bg4 29.Qd2

  • 29.Qc2 Qh5 30.Nf3 Kf7 31.Kh1 Rh8 32.Re1 Bxf3 33.gxf3 Qh4 is equal.

WHITE: Levon Aronian
Position after 29.Qd1d2


29...Rf8!

  • White can't get at Black's queenside pawns, so the Rook is free to take a direct role in the defense of the center, freeing Black's other pieces for more active roles.

30.Nd3 Ne8 31.Nxf4?

  • White must think he sees something that isn't there.
  • 31.Nf2 Bh5 32.Rg3 Rxg3 33.hxg3 Qg6 34.Nh1.

31...Rxf4 32.Rxf4 Qxf4 33.Qxf4 exf4 34.Bxf4 Rf7!

  • After the exchanges on f4, Black has a piece for three pawns. The game is now equal.

35.g3?

  • 35.Re3 Rxf4 36.Rxe8+ Kf7 37.Ra8 Be2 38.Rxa7+ Kf6 White's queenside pawns begin to fall, but the kingside paws make the game a fight..

WHITE: Levon Aronian
Position after 35.g2g3


35...Re7!

  • Rooks are happiest on open lines.

36.h3

  • The pawn sacrifice is intended to deflect the Bishop from the h5/d1 diagonal, thus making ...Re2 less likely.

36...Bxh3 37.Kf2

  • This is White's best move in that it prevents the Rook from coming behind White's pawns. Nevertheless, it is inadequate.

  • 38.Rb1 Bg4 39.Re1 Rxe1 40.Kxe1 Ne4 41.Bc1 Kg7 activates Black's King.

38...Bxg4

39.Re3 Ne4+ 40.Ke1

  • 40.Kg2 Kg7 41.Bxd6 Rf7 42.Bb8 Bf5 43.Rd3 Bg6 Black maintains a material advantage.

  • The position is quite common in master play and may result from several variations in the move order.
  • In this position, White has the edge in space and Black has the "little center" and prepares for possible opertion on the open c-file.
  • After 12.Bd3 Nb4 13.a5 Bd7 14.Qe1 Rac8 if the players want to call it a day early, then 15.Qg3 Nh5 16.Qf3 Nf6 17.Qg3 invites a repetition of moves.

Position after 18...e7e5


19.dxe6

  • White's plan is to expand on the kingside. Black will be ready counter in the center or on the opposite wing.
  • If 19.Kb1 Qc7 20.Rd2 Rc8 21.h4 then:
    • 21...Qd8 22.g5 Ba4 23.h5 Bxb3 24.axb3 Qf8 is equal.
    • 21...a5 22.h5 a4 23.Nc1 Bb5 is equal.

19...fxe6 20.Re3

  • 20.f4 Qf6 21.Re4 Bc6 22.g5 Qf5 23.Rc4 e5 24.Rxd6 gives White an extra pawn.

20...Rf7 21.Nd2 d5 22.Nb3

  • 22.h4 Ra6 23.Kb1 Qa5 24.a3 bxa3 25.Rxa3 is equal.

22...Qc7 23.Kb1 Rb8 24.Rde1?!

  • 24.h4? Rc8! 25.Rf1 Qxc2+ 26.Ka1 Qg2 27.Rfe1 gives Black one extra pawn and counting.

24...Rc8 25.R1e2

  • 25.Rc1 Ba4 26.h4 Bxb3 27.Rxb3 Qf4 28.Qxf4 Rxf4 gives White a pair of active Rooks.

25...Qb6

  • 25...Bb5 26.Rf2 Qb6 27.Rd2 Qa6 is equal.

26.h4!?

  • The text move has the drawback of restricting the Queen's freedom.
  • 26.Qh4 a5 27.g5 a4 28.Nd4 Rc4 29.Rd2 b3 gives Black more freedom.

26...d4!

  • Once again, the best antidote for action on a wing is to strike back in the center.
  • 26...Qc7 27.h5 Qf4 28.g5 gxh5 29.Qxh5 Rf5 30.Rh2 remains equal.

27.Re5

  • 27.Re4 Rxf3 28.h5 Rf1+ 29.Nc1 Rh1 gives Black an extra pawn.

27...d3

  • If 27...Rxf3 then:
    • If 28.h5 Rf1+ 29.Re1 Rxe1+ 30.Rxe1 e5 then:
      • 31.hxg6 Qxg6 32.Qxg6+ hxg6 33.Rxe5 Bxg4 is equal.
      • 31.Nxd4 then:
        • If 31...Bxg4 32.hxg6 Qxg6 33.Qxg6+ hxg6 is equal.
        • 31...exd4? 32.Re7! Qf6 33.Rxd7 gives White a strong initiative.
    • 28.Qd2 Ba4 29.h5 Bxb3 30.axb3 Rxc2 31.Qxc2 d3 gives Black the initiative.

28.cxd3 Rxf3 29.d4?!

  • Bulgarian GM Vladimir Dimitrov, commenting live on Chessdom.com, estressed disdain for the text move because now "Black transfers his Bishop to 'd3' and (wins) at least a pawn." He called 29.Qd2 "more solid" but didn't elaborate on the matter.
  • If 29.Qd2 Ba4 then:
    • 30.h5 Bxb3 31.axb3 Rf6 32.hxg6 hxg6 33.Re1 is equal.
    • If 30.Qd1 Qd8 31.Rd2 Qf6 32.Rxe6 Qxe6 33.Qxf3 Rf8 is equal.

30.R2e3 Bd3+

  • There's Dimitrov's Bishop on d3.

31.Ka1 Qxd4 32.Rxe6 Rf1+ 33.Re1 Qxg4!

  • Black has won that pawn, just like Grandmaster Dimitrov said.
  • If 33...Rxe1+ 34.Rxe1 Qxg4! 35.Qg5 Qxg5 36.hxg5 then:
    • 36...Rc2 37.Re8+ Kf7 38.Ra8 Rc7 leaves Black with an extra pawn.
    • If 36...a6 then:
      • 37.Rd1 Re8 38.Nd4 Re5 39.a4 Be4 40.Re1 Re8 gives Black an extra pawn.
      • 37.a3?! bxa3 38.bxa3 Rc3 39.Re8+ Kf7 40.Rb8 Be4 gives Black an extra pawn and the initiative.

34.Rxf1 Qxe6 35.Nc5

  • If 35.Rc1 Rxc1+ 36.Qxc1 Bf5 37.Qg1 Qe4 38.h5 a6 then:

    • 39.h6 Kf7 40.Nc5 Qf4 41.Nxa6 Qd6 42.Nc5 g5 Black still has the active game.

35...Qe2 36.Rc1 Bf5 37.Qf4 a5 38.h5

  • 38.Qd4 Qe4 39.Qxe4 Bxe4 40.a3 h6 is a more stubborn defense.

38...Qe7!?

  • If 38...Rd8 39.hxg6 hxg6 40.Qg3 a4 then:
    • 41.Nxa4 Qc2! 42.Qb3+ Qxb3 43.axb3 g5 Black has the remote passed pawn and White's King is confined to two squares.
    • 41.Qe1 Qxe1 42.Rxe1 a3 43.Rg1 Rd2 gives Black the extra pawn and the more active Rook.

39.Qc4+

  • White would get more milage from 39.hxg6 hxg6 40.Qc4+ Qf7 41.Qd4 Qd7 42.Qe5.

WHITE: Leiner Domnguez
Position after 39.Qf4c4+


39...Be6!

  • Black threatens the Queen and skewers the critical a2 square.

25.Nxb6 Qe5!

  • The ability to make this mating threat is the reason why the exchange sacrifice works in the text whereas it failed in the notes to Black's 22nd move.
  • If 25...Nxe3 26.fxe3 Qxe3+ then:
    • 27.Kh1 Qg3 28.Kg1 Qh2+ 29.Kf2 Bc5+ 30.Kf3 Bxb6 gives Black command of the dark squares.

    • 35...Rb8+ 36.Ka6 Ra8+ draws.
    • If 35...Re8?? then after 36.Rxe3! Black cannot recapture because 37.Rd8+! leads to a backrank mate.

34.Kc4 Bf6 35.Qd3 Qxg3 36.Rd1 Qc7+ 37.Rc5

24...Bc5 25.Rg3 Qf6?

  • Black fails to find the best defense. This allows White to ignite a pyrotechnic display that overwhelms Black.

    WHITE: Manuel Len Hoyos
    Position after 15.Be2h5


    15...b4!

    • White attacks with a familiar Sicilian motif.

    16.Na4 Qa5

    • 16...Qc7 17.Bf3 Rb8 18.b3 Bd7 19.Nb2 Rc8 20.Qd2 Qc3 gives Black the active game.

    17.b3 Bd7

    • 17...Bb7 18.Bf3 Bc6 19.Qb6 Qxb6 20.Nxb6 Rb8 gives Black the advantage; White has a backward pawn on the c-file.

    18.Qb6

    • Black has the advantage in space, so White forces an exchange of Queens.

    18...Qxb6 19.Nxb6 Ra7

    • 19...Rd8 20.Nxd7 Rxd7 21.g3 Rc7 22.Rd3 is equal.

    20.Nxd5

      • 22.c4 bxc3 23.Rxc3 Bb4 24.Rc8+ Ke7 25.Rd1 is equal.
      • If 22.Nc8 then after 22...Rd7 23.Nxe7 Bxd3 24.Nc6 Bb5 Black has won the exchange.

    20...exd5 21.e6

    • White cannot stop Black from bringing his rook to White's front rank.

    • Dr. Tarrasch declared that as a general rule Rook and pawn endings are drawn. Even he knew there were exceptions, but this one looks pretty lifeless at the moment. The players might have given it up sooner if they weren't playing for sole possession of first place late in the tournament.

    26...Kf6 27.Rxh7 Kf5 28.Kd2!?

    • White's best shot is 28.Rh4 Re7 29.Rh5+ Kg4 when:
      • If 30.Ra5 Kxf4 31.Rxa6 then:

    10. Jack Rabbit .. out of curiosity, would you say the virginity
    rate among your hobby is higher than 85 percent?

    Or would you say it's closer to 95-98 percent?

    Not that there's anything wrong with it.

    I'm just wondering.

    13. Old news story from 2006
    From ChessBase.com
    Dated 16 May 2006
    (with emphasis added)


    Topalov-Radjabov game for the world title agreed
    The prize fund is $1.5 million.

    Sofia, May 15, 2006 The manager of the Chess World Champion Veselin Topalov, Silvio Danailov, and the Minister of Sport of Azerbaijan Azad Rahimov, agreed yesterday on a game for the world title to be held between Topalov and the Azerbaijanian Teimour Radjabov (Elo 2720). All conditions of the World Champion have been accepted and the two sides have signed a memorandum.



    The Minister of Sport of Azerbaijan, Azad Rahimov, with Topalov's manager Silvio Danailov

    The match will probably take place in April 2007 in Baku. The award fund will be $1.5 million, of which $1 million will be for Topalov. According to the rules of FIDE every chess player with an Elo rating over 2700 can challenge the World Champion in a game for the title. Radjabov, currently number 13 in the FIDE ranking, will be the next challenger if Topalov defends his title in the game against Kramnik in September this year in the capital of Kalmykia, Elista.


    As we know, the Topalov lost the reunification match to Kramnik and the proposed match between Topalov and the young Azerbaijani GM Radjabov never took place.

    Also from the article, here is a picture of Azerbaijani Sport (my emphasis again) Minister Rahimov making the ceremonial first move at the MTel Masters Tournament in Sofia, Bulgaria, where the Sport Minister, representing Radjabov, took part in negotiations with representatives of Topalov and FIDE, the world chess federation.

    15. Of course it is

    All it needs is a professional level of competition and a world governing body to enforce uniform rules. It also helps if government agencies responsible for supporting sports events, such as the Ministry of Sports in Azerbaijan, assist in organizing Twister tournaments as they do in organizing chess tournaments and the Olympic Games.
