The JR Chess Report (May 2): Aronian Wins GP with Dramatic Victory in Final Round
Aronian Wins GP with Dramatic Victory in Final Round



Armenian grandmaster Levon Aronian took a clear first place in the Nalchik Grand Prix when he defeated his closest rival, former challenger for the world title Peter Leko of Hungary, in the 13th and final round Wednesday.

Aronian and Leko entered the final round tied for first place with 7 points each. The day before, Leko defeated Uzbek GM Rustam Kasimdzhanov to move into a tie with Aronian, who drew his twelfth round game with Russo-American GM Gata Kamsky, to set up the showdown.

Aronian played White in the final round. Both competitors were clearly playing for a win, taking risks when the opportunity presented itself. Aronian started pressing his advantage with an exchange sacrifice on his 34th move; on move 54, Aronian offered to trade Queens and sacrifice his kast remaining piece, a Bishop, with check, which would have left him with two advancing passed pawns, one already on the seventh rank, which Leko's remaining Rook could not stop from promoting. Leko resigned rather than continue a lost cause. (See the game below.)

Being that the Grand Prix is a round robin tournament, the last round pairing was purely coincidnetal, having been decided by drawing lots two weeks ago before the first round. In Swiss system events, such last round showdowns are common.

Aronian's compatriot, Vladimir Akopian, who started the tournament badly with two losses in the fisrt three rounds, roared back to finish tied with Leko for second when he won his final game with Black against Ukrainian GM Pavel Eljanov.


Eight tied for first after 7 rounds in Dubai



The eleventh annual Dubai Open staged its sixth and seventh rounds of a scheduled nine today with eight palyers ending the action tied for first place.

Among those at the top is Azerbaijani GM Gadir Guseinov, the tournament's top seed, Valim Malakhatko of Belgium by way of Ukraine, the number three seed, Armenia's Tigran Kotanjian, re-entering first palce after being there after round four but dropping out of it after losing in round five, and Levan Pantsulaia of Georgia, a former Dubai champion.

The tournament continues tomorrow with live games broadcast on the website of the Dubai Chess and Culture Club starting at 5:30 pm in Dubai (6:30 am in California). The last round is scheduled for Monday.

  • For the more usual 6.e3 c5 7.dxc5 Bxc5 8.a3 see Eljanov-Chadaev, Russian ChT, Sochi, 2009.

6...exd5 7.Qb3

  • If 7.e3 c6 8.Bd3 then:
    • If 8...0-0 9.0-0 Re8 10.Rc1 Nf8 11.Ne5 then:

      • 11...N8d7 12.h3 Nxe5 13.Bxe5 Bd7 14.f4 Be6 15.Qf3 Be7 16.g4 is equal (Dr. Alekhine-Rodrguez, SX, Montevideo, 1928).
    • 8...Ne4 9.Qc2 Ndf6 10.0-0 Bxc3 11.bxc3 0-0 12.Ne5 h6 13.c4 Qa5 14.cxd5 cxd5 15.f3 Ng5 16.Rab1 gives White the advantage in space and activity (Razuvaev-Pesantes, Capablanca Mem, Cienfuegos, 1975).

7...c5 8.dxc5 Qa5 9.a3 Bxc3+ 10.bxc3

  • 10.Qxc3 Qxc3+ 11.bxc3 Nxc5 12.e3 Nfe4 13.c4 dxc4 14.Bxc4 Be6 15.Bb5+ Ke7 16.Nd4 Rac8 17.0-0 Nc3 18.Rfc1 Nb3 19.Nxb3 Bxb3 20.Bf1 Rc6 21.e4 Rhc8 22.f3 a6 23.Kf2 Ba4 24.Bd2 draw (Kaufman-Seirawan, US Ch, Seattle, 2002).

10...Qxc5 11.Qb4!?

  • 11.Nd4 0-0 12.e3 Re8 13.Be2 Ne5 14.Qb4 Ne4 15.Nb5 Qc6 16.Rc1 Qg6 17.0-0 Bh3 18.Bg3 Nxg3 19.hxg3 Bg4 is equal (Naumkin-Dreev, Moscow, 1987).

11...Ne4

  • 11...b6 12.e3 Ne4 13.c4 Qxb4+ 14.axb4 dxc4 15.Bxc4 gives the the advantage in space.

12.Nd4 b6!?

  • White settles for a pssive move when he could go in for a queenside initiative.
  • 12...Nxc3 13.Qxc5 Nxc5 14.Rc1 N3a4 15.Nb5 Ne6 16.Nc7+ assures that White will have compensation for the pawn.

13.f3 a5

  • 13...Qxc3+ 14.Qxc3 Nxc3 15.Rc1 Na4 gives White a more active game.

14.Qxc5 Nexc5 15.Nf5

  • If 15.Rd1 Bb7 16.Nf5 then:
    • If 16...Ne6 17.Nd6+ Kf8 18.Nxb7 Nxf4 19.e3 then:
      • 19...Ke7 20.exf4 Ra7 21.Rxd5 Rxb7 22.Bb5 gives White an extra pawn.
      • 19...Rb8 20.Nd6 Ke7 21.Nf5+ White continues to enjoy the initiative.
    • 16...Rg8 17.Nd6+ Ke7 18.Nxb7 Nxb7 19.Rxd5 Rac8 20.Kd2 gives White an extra pawn.

15...Ne6

  • If 15...Rg8 then White continues to enjoy more activity after 16.Rb1 Ne6 17.Bg3 g6 18.Nd6+.

16.Bg3 g6 17.Nd6+ Ke7 18.e3!?

  • This move is to keep Black's Knight out of f4, but the Bishop is already doing that. White has a more aggressive option.
  • If 18.Rd1! Nf6 19.e4 dxe4 20.fxe4 Ng4 21.Nc4 forces Black to move his Rook to the awkward post at 16 in order to protect his b-pawn.

18...Rd8!

  • Black equalizes.
  • 18...h5 19.Nb5 Bb7 20.c4 dxc4 21.Bxc4is also equal.

19.Rb1 Ba6 20.Kf2 f5 21.Nb5 Rdc8 22.Be2

  • If 22.Bd6+ Kd8 23.Rd1 Nf6 24.Be5 Ke7 remains equal.

22...Bxb5 23.Rxb5 Rxc3 24.Rxd5 Nf6?!

  • Black takes the pressure off of c5.
  • 24...Rac8 25.Ra1 Nec5 26.Bh4+ Nf6 27.Bxf6+ Kxf6 28.Rd6+ remains equal.

Position after 24...Nd7f6


25.Rd2

  • If 25.Bd6+ Kf7 26.Rb5 Nd7 27.Rd1 then:
    • 27...Nec5 28.Bxc5 Nxc5 29.Rxb6 Rxa3 30.Rd5 gives White the initiative.
    • 27...Rac8 28.Bb4 R3c7 29.Bc3 Ke7 is equal.

25...Nc5 26.Rb1 Nfe4+

  • The text is better than 26...Rxa3 27.Rxb6 when:
    • 27...Nfe4+ 28.fxe4 Nxe4+ 29.Ke1 Nxg3 30.hxg3 Rxe3 31.Rb7+ White has a Bishop for two pawns.
    • 27...Nfd7? 28.Rc6! Rc3 29.Rc7 Rb3 30.Bd6+ Kd8 31.Rxc5 gives Black two Bishops for a Rook.

27.fxe4 Nxe4+ 28.Ke1 Nxd2 29.Kxd2

  • White has two Bishops in an open center for a Rook and a pawn.

29...Rxa3 30.Bh4+ Kf7?!

  • Eljanov had drawn even in the tournament standings in the eighth round and wanted a win to further improve his position going into the final rounds.
  • Nevertheless, in the present position he can hope for little better than a darw and passes an opportunity to force the issue.
  • 30...Ke8 31.Rxb6 Ra2+ 32.Kd3 Ra3+ 33.Kd2 draws.

31.Bc4+ Kg7 32.Rxb6 Ra4

33.Bf6+!

  • Also good is 33.Bd5! Rc8 34.Bf6+ Kh6 35.Rb5 Rf8 36.Bc3.

33...Kh6 34.Rc6 Ra7 35.h4!?

  • The players are entering the stage of the game where each should be concerned about reserve pawn tempi. White just wastes one without any apparent compensation.
  • 35.h3 is more precise: if now 35...Rb4 then 36.g4 fxg4 37.hxg4 Rd7+ 38.Kc2 White's Bishops control more ground that Black's extra Rook.

35...Kh5?

  • Black fails to take advantage of White's inaccuracy.
  • 35...Rb4 36.Kc1 Rab7 37.Bc3 Rb1+ 38.Kc2 Rg1 gives Black some counterplay.

36.Ke1 Rb7

  • If 36...Rb4 37.Bg5 then:
    • 37...Rxc4 38.Rxc4 a4 39.Bf6 a3 40.Kd2 a2 41.Ba1 gives White the material advantage, but for now he must invest part of it in defending against the advanced passer.
    • 37...Kg4 38.Kf2 Rb2+ 39.Be2+ forces Black to surrender the exchange.

37.Kf2 Rab4

  • If 37...Rbb4 38.Bd5 Rxh4 39.Rc1 then:
    • 39...Kh6 40.Bxh4 Rxh4 41.Ra1 a4 42.e4 fxe4 43.Bc6 gives White a piece for two pawns.
    • 39...Rh2 40.Rc7 Kh6 41.Bg8 wins easily for White.

38.Bg5 Rb2+

  • 38...Rxc4 could have been played here, too, but the game is going to it's final phase in any event.

39.Be2+!

  • Were the Black Rook not on the second rank, this would be checkmate.

39...Rxe2+ 40.Kxe2 Kg4 41.Kf2 Rb2+ 42.Kg1

  • 42.Ke1 Kg3 43.Rc7 h5 44.Rc6 wins a pawn for White, leaving him a whole piece to the good.

42...Kg3 43.Bf4+ Kxh4 44.Rc7 h5 45.Rc4 Rb4 46.Rd4 g5 47.Bd6+!

  • Lights out!

47...Rxd4 48.exd4 Kg4 49.d5 f4 50.Bxf4 1-0

  • If 50...Kxf4 then after 51.d6 the White pawn stays one step ahead of the Black King.

    • If 52...Ke5 53.d6 Ke6 54.Kf2 Kd7 55.Ke3 then:

    • 55...Kd8 56.Ke4 g4 57.Kf5 Kd7 58.Kg5 the White Kings eats the kingside pawns.
  • Eljanov resigns.

  • The Knight has nowhere to go from a4.
  • The retreat is better: 13.Ne2 a5 14.Qd3 a4 15.Nd2 Na5 16.Qd4.

13...Qc7!?

  • Slightly better is 13...Qb7! (better protecting Black's queenside pieces) when if 14.c4 then 14...Nd8! 15.e5 fxe5 16.fxe5 Bxa4 wins the Knight.

14.Qf2 Rb8 15.f5??

  • There are two things wrong with this move: first, it does nothing about the hanging Knight at a4; second, it Black's Knight a splendid outpost to move, discovering attack on the hanging Knight that has nowhere to go.
  • Correct is 15.Na1! Ne7 16.b3 (both protecting the Knight and opening a square to which it can retreat) 16...f5 then:
    • 17.Qd4 Rg8 18.Qxd6 Qxd6 19.Rxd6 fxe4 20.Rxa6 Nd5 Black is better, but White's game is playable.
    • 17.exf5 Bxa4 18.bxa4 Bg7 19.Qe1 Bxa1 20.Kxa1 Qxc2 leaves Black better, but Whit can fight on.

Position after 15.f4f5


15...Ne5!

16.fxe6 Bxa4 17.Qxf6 Rg8 18.Bxa6 Rxg2 19.exf7+ Qxf7

  • White has only two pawns for the Knight and those are weak.

20.Qh4

  • If 20.Qxf7+ Kxf7 then:
    • If 21.Rdg1 Rxg1+ 22.Rxg1 Rb6 23.Be2 then:
      • 23...Bxb3 24.cxb3 Bg7 25.Bc4+ Nxc4 26.bxc4 Rc6 Black's material advantage is now decisive.
      • 23...Bc6 24.Bd3 Bg7 25.Nd4 Bb7 26.Rf1+ Bf6 Black has a winning position.
    • 21.Rdf1+ Ke7 22.Nd4 Rd2 23.Rd1 Rf2 24.Rdf1 Rxf1+ maintains the material advantage for Black.

20...Qg6 21.Rhf1 Be7 22.Qe1

  • 22.Qf4 Rb6 23.Bd3 Nxd3 24.cxd3 Bxb3 25.axb3 Qe6 is time to turn out the lights.

22...Rxh2 23.Qe3 Bc6 24.Qf4 Rxc2

  • Black is a whole piece to the good. The rest requires no comment.

14. Update (Monday): Dubai Open ends in three-way tie
Russian grandmaster Dmitry Bocharov and Armenians Tigran Kotanjian and Ashot Anastasian finished the 11th annual Dubai Open ahead of all others with 7 points out of nine rounds after the final round was played today.

It appears Kotanjian will take home the trophy based on his superior tie-break score.

Among women competing in the event, the best scores were turned in by WGM Zeinab Mamedyarova of Azerbaijan, the older sister of grandmaster Shakhriyar Mamedyarov, and WGM Atousa Pourkashyian, who recently won her third Iranian women's championship at the age of 20. The pair scored 5 points each to edge out Russian Irina Turova, who scored 5 points.
