The JR Chess Report (May 23): Is the G. W. Bush of chess stealing the FIDE election?
Edited on Sun May-23-10 03:34 PM by Jack Rabbit
Is Kirsan Stealing the FIDE Election?



Political intrigue now taking place in Russia would make it appear that Kirsan Ilyumzhinov, the incompetent and corrupt president of both the FIDE, the world chess federation, and the Russian Autonomous Republic of Kalmykia, is attempting to assure his re-election as FIDE president by coup d'etat.

Kirsan, known not necessarily affectionately in the world wide chess playing community by his first name, is often called in these reports the "George W. Bush of Chess" for his habit of coming up with big ideas than never seem to pan out or just weren't very good in the first place. To extend the Bush analogy, the part of Florida in recent events is being played by the Russian Chess Federation and the part of Katherine Harris by Arkady Dvorkovich, a top official of the RCF and a supporter of Ilyumzhinov's re-election bid. Al Gore is portrayed by an unlikely performer for the part, former world champion Anatoly Karpov, who is opposing Kirsan in his bid for re-election. There is a very real possibility that somebody in the Russian government is playing the part of Jeb Bush, acting behind the scenes to make sure things come out the way they're supposed to come out, regardless of the will of the voters.

One week after a quorum of RCF board members voted to endorse the candidacy of Anatoly Evgenyevich, members of a private security firm invaded the RCF's offices in Moscow, ejected board chairman Alexander Bakh, a Karpov supporter, from his office and seized the federation's bank accounts. The security firm was apparently acting on orders from a government official.

Dvorkovich had been claiming all week that the vote of the board members was invalid because he was not present. The fact is that on May 14, the day of the vote, Dvorkovich first tried to change the site of the meeting, then tried to cancel it and then told Kirsan's supporters on the board to not attend in the hopes that it would deny Karpov's supporters a quorum. All such actions failed. Seventeen of the 32-member board met and voted unanimously to endorse Karpov.

Prior to the vote, on May 3, Dvorkovich had issued a statement to the effect of the RCF had endorsed Kirsan's candidacy for re-election. Karpov immediately objected, pointing out that no vote had been taken at that time and that Dvorkovich had no authority to sign off on the endorsement in any event. Only the chairman of the RCF board, Bakh, could do that.

In order to be elected president of FIDE, a candidate needs to have the support of a delegation of which he is a member. For Karpov, this is not a serious problem, since in addition of being a member of the Russian Federation he is also a member of the German Federation due to the fact he competed in the Bundesliga many years ago. Kirsan, who was a talented youngster in Kalmykia (he was the Kalmykian champion at the age of 14), never became an international star in chess and is a member only of the Russian Federation. There was some talk that he could be nominated by the presidential board, but that appears to have about as much validity as the claims of such Bush Administration constitutional scholars as Dick Cheney and David Addington, who apparently could read invisible ink on the Constitution that nobody else could. The claim would certainly be challenged, and if Kirsan were overruled he would be ineligible for re-election.

Big Four in Quad Final of US Championship



The "Big Four" of American chess -- Gata Kamsky, Hikaru Nakamura, Alex Onischuk and Yuri Shulman -- are currently taking part in the final phase of the 2010 US Championship in St. Louis, a three-round mini-tournament to determine the new champion.

The quadrangular touranament, or the "Quad" as it is called in St. Louis, began yesterday with Nakamura playing White against Kamsky and Onischuk playing White against Shulman. Both games ended in draws.

In the round starting as we go to press (2 pm CDT/12 noon PDT), Nakamura plays White against Shulman and Kamsky has White against Onischuk. There is a live broadcast featuring commentary by US grandmaster Maurice Ashley and WGM Jennifer Shahade on the http://saintlouischessclub.org/2010-us-championship">official website of the St. Louis Chess Club and Scholastic Center.

The battle for fifth place, called the "challenger tournament," continues today among the 20 other players in the tournament with grandmaster Alex Stripunsky currently a half point ahead of former US champion Alex Shabalov.

The challenger tournament concludes today while the Quad is scheduled to finish tomorrow, with speed chess play offs, if necessary, scheduled for Tuesday.



Eljanov leads Astrakhan Grand Prix



Ukrainian GM Pavel Eljanov leads the sixth and final leg of the 2008-09 FIDE Grand Prix (being played in May 2010) with one round remaining in the Russian city of Astrakhan in the Volga Delta near the Caspian Sea.

Pavel Vladimirovich is assured of at least a share of first prize as he leads a half d0zen other players by a full point and need only avoid loss in the final round to take first place clear.

The final round will be played tomorrow.

US Championship, Round 5
St Louis, 18 May 2010

Spanish Petit Royal Game: Pogo Stick Defense
(Bird's Defense)


1.e4 e5 2.Nf3 Nc6 3.Bb5 Bc5

  • This is the variation of the Ruy Lopez analyzed by Ruy Lopez in the 16th century. For three hundred years thereafter, the Spanish Game in general was considered pedestrian and most masters preferred to play the King's Gambit; the Italian was their idea of a "quiet game."

4.0-0 Nd4


5.Ba4 Nxf3+ 6.Qxf3 Ne7

  • If 6...Qf6 7.Qg3 Ne7 8.d3 h6 9.Nc3 c6 then:
    • If 10.Kh1 Ng6 then:
      • 11.Ne2 Qh4 12.Qxh4 Nxh4 13.f4 exf4 14.Bxf4 gives White better development and the advantage in space (Oral-Schutz, Op, Brataslava, 1990).
      • 11.Be3 Bd6 12.Ne2 Nf4 13.Qf3 Nxe2 14.Qxe2 0-0 15.Rad1 Bc7 16.d4 d5 17.exd5 is equal (Dr. Tarrasch-Allander, SX, Eskiilstuna, 1913).
    • 10.Be3 Bxe3 11.Qxe3 Ng6 12.Ne2 0-0 13.c3 Nf4 14.Nxf4 exf4 15.Qf3 d6 16.d4 gives White the advantage in space (Brodsky-V. Shulman, Op, Kstovo, 1994).

7.Qc3!?

  • If 7.d3 0-0 8.Nc3 d6 then:
    • 9.Bg5 Be6 10.Rad1 Bb6 11.Bb3 Qd7 12.Bxe6 fxe6 13.Qg4 Rf7 14.Be3 Nc6 is equal (Ivanesovic-Nikolic, Yugoslav Ch, Kladovo, 1991).
    • 9.Be3 Bb6 10.Bb3 Be6 11.Qg3 Bxb3 12.axb3 f5 13.Bxb6 axb6 14.Qh4 Qd7 is equal (A. Sokolov-Gulko, City Ch, Moscow, 1981).

7...Bd4

  • The game is equal.

8.Qg3 Ng6 9.c3 Bb6 10.d4 0-0

  • 10...exd4 11.Rd1 dxc3 12.Nxc3 Qe7 13.Bg5 Qe5 remains equal.

11.f4!?

  • This pawn advance loosens Black's kingside.
  • 11.Be3 Qe7 12.Bc2 exd4 13.Bxd4 d6 14.Nd2 remains equal.

11...exf4!?

  • Black takes the wrong way.
  • If 11...exd4! then:
    • 12.Kh1 dxc3 13.Nxc3 c6 14.Rd1 Bc7 15.e5 gives Black an extra pawn.
    • 12.cxd4? Bxd4+! 13.Kh1 Qf6 gives Black an extra pawn and he will certainly get another.

12.Bxf4 Nxf4

  • 12...d5 13.exd5 Qxd5 14.Bc2 Nxf4 15.Rxf4 c5 remains equal.

13.Qxf4

  • White gets the advantage in space from his central pawn duo.

13...d6 14.Nd2 Be6 15.Kh1 c6 16.Nf3 h6 17.Bc2 Qd7 18.e5 dxe5

  • 18...d5 19.Qe3 Bf5 20.Bxf5 Qxf5 21.Nh4 gives White a slight advantage in space.

19.Nxe5 Qd6

  • If 19...Qd5!? then 20.Qd2! Qb5 21.a4 Qd5 22.Qd3 f5 23.Ng6 gives White the initiative.

20.Qg3 f5!?

  • Black plays on the wrong wing. His pieces are queenside, so pawn advances should be made there to work hand-in-hand with the pieces.
  • 20...c5 21.dxc5 Bxc5 22.b4 Bb6 23.Rad1 Qc7 restores equality.

21.Rae1 Bc7!?

  • White makes another inaccuracy. Having advanced the f-pawn, he should bring his Rooks to the kingside.
  • If 21...Rae8 22.Qg6 Bc7 23.Ng4 then:
    • 23...Bc4 24.Nxh6+ Kh8 25.Qxd6 Bxd6 26.Rxe8 Rxe8 is equal.
    • 23...Kh8 24.a4 Bg8 25.Qxd6 Rxe1 26.Rxe1 Bxd6 27.Ne5 gives White a small advantage in space.

22.Qh3!

  • The Queen has a paralyzing effect on Black's position.
  • 22.a4 c5 23.dxc5 Qxc5 24.b4 Qe7 25.Qe3 leaves White with a very slight edge in space.
  • 22.Qg6!? Rf6! 23.Qh5 Bxa2 24.Rxf5 Raf8 25.Ref1 is equal.

22...f4?

  • Black opens the h7/b1 diagonal for White's pieces to attack the Black King.
  • 22...Bxa2 23.b3 c5 24.Ra1 cxd4 25.Nd3 dxc3 26.Rxa2 Black still has a defensible game.

Open Queen's Gambit: Catalan Opening


1.d4 Nf6 2.c4 e6 3.g3 d5 4.Bg2 dxc4 5.Nf3 a6 6.Ne5

  • Now that Anand and Topalov have completed their match, one should expect pawn sacrifices in the Catalan to become fashionable for a while.

6...Bb4+

  • The text sets up a situation similar to the fourth game of the Anand-Topalov match, except Black's fifth and White's sixth move had not been played.
  • 6...c5 7.Na3 cxd4 8.Naxc4 Bc5 gives Black an extra pawn; see Anand-Topalov, World Ch Match Rd 2, Sofia, 2010.

7.Nc3

  • 7.Bd2!? Qxd4 8.Bxb4 Qxe5 9.Na3 Nc6 10.Bxc6+ bxc6 11.Bc3 Qd5 12.f3 e5 gives Black two extra pawns and more space (Aronian-Mamedyarov, Euro Club Cup, Ohrid, 2009).

7...Nd5 8.Bd2 Nb6

  • 8...b5 9.0-0 Bxc3 10.bxc3 0-0 11.a4 f6 12.Nf3 c6 13.Qc2 Bb7 14.h4 Qe8 15.Rfe1 Nd7 16.e4 Nc7 gives White more space and Black an extra pawn (D. Gurevich-Hess, World Op, Philadelphia, 2009).

9.e3 N8d7 10.Nxd7

  • 10.Qg4 0-0 11.Rd1 Qe7 12.0-0 Rb8 13.Qe2 Nxe5 14.dxe5 Bd7 leaves Black with an extra pawn (Sherevich-Kachiani, OlW, Torino, 2006).

10...Qxd7 11.Ne4 Qb5 12.0-0!?

  • 12.Bxb4 Qxb4+ 13.Qd2 a5 14.0-0 Bd7 15.a3 Qxd2 16.Nxd2 0-0-0 gives Black an extra pawn and White more space (Vidit-Zhou Jinchao, Asian Ch, Subic Bay, 2009).

12...0-0

  • Black has an extra pawn; White has more space.

13.a4 Qa5 14.Qe1

  • 14.Bxb4 Qxb4 15.Qd2 a5 16.Qxb4 axb4 17.Rfc1 remains equal.

14...Bxd2 15.Qxd2 Qxd2!?

  • Black does not have a serious space deficit and needn't exchange Queens.
  • 15...Qh5 16.h4 a5 17.Qd1 Qg6 18.h5 Qh6 gives White more space and Black an extra pawn.

16.Nxd2 Bd7 17.a5!?

  • White misses a shot to turn the game around.
  • If 17.Rfc1 then 17...Bxa4 18.Nxc4 Bc6 19.Bxc6 bxc6 20.Ne5 assures White of winning back the pawn with greater piece activity.

17...Nd5 18.Rfc1

  • The c-pawn isn't poisoned. White should just take it.
  • 18.Nxc4 Rad8 19.Rfd1 f6 20.Rac1 Bc6 21.e4 gives White the advantage in space.

18...Bb5 19.Bf1 c5 20.dxc5

  • White has restored the material balance.

20...Rfc8

  • If 20...Rac8 then 21.Nxc4 Rxc5 22.Nd6 Rxc1 23.Rxc1 Bxf1 24.Kxf1 wins Black's b-pawn.

  • &&
  • 20...c3 21.bxc3 Bxf1 22.Kxf1 Rfc8 23.Rab1 Rab8 24.Nb3 gives White an extra pawn.

21.Nxc4 Rxc5 22.Nb6!?

  • This allows for an exchange of Knights with only diminishes White's attack.
  • If 22.Nd6 Rxc1 23.Rxc1 Bxf1 24.Kxf1 then:
    • 24...b5 25.e4 Nb4 26.Ke2 f6 27.Rc7 gives White greater piece activity.
    • 24...f5? 25.Nxb7! Kf7 26.Rc6 Nb4 27.Rc7+ leaves White a pawn to the good.

  • Black drops a pawn at a crucial moment.
  • 25...Bxg2! 26.Kxg2 Rb8 27.f4 h6 28.Rc7 g5 29.Kf3 gives White the clearly more active Rook, but Black has better queenside pawns and thus a defensible game.

    11. Shabalov - Christiansen, Round 4
    This game is a real slugfest between two veteran heavy hitters. One learned the finer points of chess from Tal himself; the other has just spent forty years playing like he did.

    • Also good for Black is 26...Bxd2 27.Rxd2 Nb6 28.Nd3 Nc4 29.Rdc2 a5.

    27.Nd3?!

    • White neglects protecting the d-pawn, but he would lose the b-pawn otherwise.
    • If 27.Nef3 then Black wins the b-pawn after 27...Bxd2 28.Rxd2 Nc4 29.Rdc2 Rxb2 30.Rxb2 Nxb2.

    27...Bxd2!

    • Black removes a potential defender of the queenside.

    31...f6 32.Re2 Kf7 33.exf6 gxf6 34.Rae1

    • Black cannot save the b-pawn, so he looks for compensation elsewhere.
    • 34.Kg2 R8b6 35.Ree1 Nxb2 36.Nxb2 Rxb2 37.Rxa5 Rd2 leaves the Black Rooks lunching on White's pawns.

    34...R8b6 35.Nf4?

    • Although with White committed to abandoning the b-pawn the Knight is of little use at d3, this move is premature. White could use the tempo to his kingside pawns into a safer formation.
    • If 35.h3 then after 35...Nxb2 36.Nf4 a4 37.Rxe6 Rxe6 38.Nxe6 Nc4 Black wins the b-pawn giving Black an advanced passer, but White still has the resources to make its promotion less than inevitable and can whip up counterplay with his stronger kingside pawns.
    • Fixing the e-pawn with 35.f4? proves futile 35...Rb3 36.Nc5 Rxb2 37.Rxb2 Rxb2 38.Kg1 Rb6 when Black has won the b-pawn and his e-pawn remains perfectly safe.

    • Black simply reinforces the b-pawn.

    • 21.Rac1!? then 21...Bb4! 22.Bd2 Bf8 23.b4 Rac8 24.h3 c5! gives Black the advantage in space.

    • The game is again equal.
    • 21...Rad8 22.fxg4 Bxd4+ 23.Nxd4 Rxd4 24.Qf2 Rexe4 gives Black the advantage in space.

    22.Kg2 Bf8 23.Nf5

    • If 23.Bxe5 Rxe5 24.Qc3 b4 25.Qc4 then:
      • 25...Qc5 26.Qxc5 Rxc5 27.h3 Rd8 28.f4 Re8 remains equal.

      • 26.Nc3 b4! 27.Nd5 Bxd5 28.Rxd5 Rxd5 29.exd5 g6 forces the Knight to retreat to h4, a bad square.
      • 26.Nd6 Bxd6 27.Rxd6 f5 28.Rad1 Qa8 gives Black the tactical edge with the threat of 29...fxe4.
    • 24.Nf5? Nxf3! 25.Kxf3 Bxe4+! 26.Qxe4 Rxe4 27.Kxe4 Qb7+ puts White's King in a open center and gives Black pawn majorities on both wings.

    23...c5 24.Nc3 c4! 25.Bxe5!?

    • By now, White sees the danger in in allowing Black to play his Knight to d3. Nevertheless, there are other ways of dealing with the situation than exchanging his good Bishop.
    • Inadequate is 25.Be3!? Qb8 26.Bf4 Qc8 27.Nd5 Bxd5 28.Rxd5 Nd3! when White must contemplate sacrificing the exchange to prevent the octopus at d3 from being a bone in his throat for too long.
    • Best is 25.b3! (undermining the outpost) then:
      • 25...Rac8 26.Bxe5 Rxe5 27.bxc4 Rxc4 28.Nd6! leads to an equal game.

    12. Updates (Tuesday): Gata Kamsky new US National Champion
    Edited on Tue May-25-10 12:53 PM by Jack Rabbit


    Gata Kamsky, a Soviet-born American of Tatar descent, won his first US national championship since the early 1990s minutes ago when he defeated his friend and training partner Yuri Shulman in a rapid Armageddon game in St. Louis.

    Shulman, who was also born in the old Soviet Union, drew Kamsky yesterday in the final round of the quadrangular championship to tie Kamsky for first place.

    In today's game, the players started with a base time of 60 minutes, but put in bids of time for the right play Black with the odds of draw (meaning that for Black a draw would be as good as an outright victory). Shulman, not noted for his speed chess skills, all but conceded Black to Kamsky by bidding 40 minutes while Kamsky bid 25, which some commentators thought very low. Shulman played a solid Queen's pawn opening which morphed into a Slav-Grünfeld Defense and appeared to have the upper hand by about the thirtieth move. However, an inaccuracy allowed Kamsky to equalize if not get the better game. On the 66th move Shulman, seeing he could not win the game, agreed to a draw.

    Kamsky last won the US Championship in 1991.

    Eljanov wins Astrakahn Grand Prix



    Ukrainian grandmaster Pavel Eljanov took first place in the sixth and final leg of 2008-09 FIDE Grand Prix (yes, we know it's the end of May 2010) yesterday with 8 points out of 13 rounds in the city of Astrakhan in the Volga Delta.

    Pavel Vladimirovich finished a full point ahead of fellow Ukrainian GM Ruslan Ponomariov, Russians Dmitry Jakovenko and Evgeny Alekseev, former two-time junior world champion Shakhriyar Mamedyarov of Azerbaijan and Teimour Rajabov, also from Azerbaijan.

    The Grand Prix series was won by Armenian grandmaster Levon Aronian, who did not participate in Astrakhan having already cinched the title. While FIDE has not yet posted the final results, it appears that second place will go to Rajabov.


    Chinese Championships begin in Xinghua



    The annual Chinese National Chess Championships began yesterday in Xinghua in Jiangsu province.

    The defending champion in the general group is Ding Liren, who last year was untitled but this year competes as a grandmaster. Ding is off to a poor start, losing in the first round to last year's runner up, Wang Hao, and in today's second round to Ni Hua.

    The leaders after two rounds are Bu Xiangzhi and Li Shilong with perfect scores.

    As last year, it is indeed improper to refer to the general group as the "men's group," as Hou Yifan is again playing with the guys.

    Shen Yang is the defending women's champion. The leaders after two rounds are Gu Xiaobing, Huang Qian, Ju Wenjun and Wang Doudou with a point and a half each.
