The Jack Rabbit Chess Report (December 7): The FIDE Follies
The FIDE Follies



Kirsan Ilyumzhinov is the George W. Bush of chess. OK, I know. That one's getting old. So is Kirsan's autocracy over FIDE.

At the close of the 38th Olympiad in Dresden last week, FIDE had an annoucement to make about the current world championship cycle. Kirsan is changing the rules at his pleasure again.

It's all a little confusing. The next challenger ofr the world championship is supposed to be chosen in a series of six Grand Prix tournaments. Except now it looks like there will only be four Grand Prix tournaments. The system is crubling finacially.

So Kirsan has chosen to introuduce a new system without asking the players who have been competing in the Grand Prix what they think about it.

Magnus Carlsen, who turned eighteen as the Dresden games completed, announced his withdrawal from the Grand Prix.

Levon Aronian has suggested the Kirsan review the decision, and reverse it.

Alexei Shirov has suggested banning FIDE. That may be the best idea of all.

Meanwhile, grandmaster Vassily Ivanchuk refused to take a drug test after game in Dresden which he lost. FIDE is threatening the popular Ukrainian GM with a two year ban from chess.

  • If 5.d4 exd4 6.Qxd4 Qxd4 7.Nxd4 Bd7 then:
    • If 8.Be3 0-0-0 then:
      • 9.Nd2 Ne7 10.0-0-0 c5 11.N4f3 Nc6 12.Ng5 Be8 13.f4 b6 14.Ndf3 Be7 15.Rxd8+ Nxd8 16.e5 Bc6 17.Rf1 f5 18.exf6 gxf6 19.Nh3 Rg8 (Trevelyan-Jenni, Euro ChT, Saint Vincent, 2005).

    • 8.0-0 0-0-0 9.Nc3 f6 10.Be3 Bd6 11.Rad1 Ne7 12.Nb3 Rhe8 is equal (Pintor-Sekulovska, OlW, Torino, 2006).
  • 8.Nc3 tranposes into the text or the note following White's ninth move in this variation.
  • For 5.0-0 (Fischer's Exchange Opening), see Bojkovic-Zhao Xue, OlW Rd 9, Dresden, 2008.

5...f6 6.d4 exd4 7.Qxd4

  • If 7.Nxd4 c5 8.Nde2 Qxd1+ 9.Nxd1 then:
    • If 9...Be6 10.Bf4 0-0-0 11.Ne3 Ne7 12.Rd1 Rxd1+ 13.Kxd1 f5 14.Kc1 fxe4 15.Nc3 Nf5 16.Nxf5 Bxf5 17.Nd5 c6 18.Nb6+ Kd8 19.Rd1+ Ke8 20.Bg5 Be7 is equal ( Sherbakov- Sherbakov, Russian Ch, Krasnoyarsk, 2003).
    • 9...Bd7 10.Bf4 0-0-0 11.Ne3 Bc6 12.f3 Ne7 13.Rd1 Rxd1+ 14.Kxd1 Ng6 15.Bg3 Be7 16.h4 h5 17.Kc1 Bd8 18.Rd1 Rf8 19.b3 gives White more freedom (Landa-Malaniuk, Op, Chappelle la Grande, 1995).

7...Qxd4 8.Nxd4 Bd7 9.f3

  • If 9.Be3 0-0-0 10.0-0-0 Ne7 11.Nde2 Ng6 12.h4 h5 13.Nf4 Ne5 is equal (Sahu-Geller, IT, Coimbatore, 1987).

9...0-0-0 10.Kf2 Ne7 11.Be3 f5!?

  • This new move is good for equality.
  • 11...Ng6 12.Rad1 Bd6 13.Nde2 Rhe8 14.h4 Ne5 15.b3 c5 16.Rd2 Bc6 17.Rhd1 Bf8 18.Rxd8+ Rxd8 19.Rxd8+ Kxd8 20.Nf4 Kd7 21.g4 draw (Kochyev-Savon, Op, St. Petersburg, 1994).

    • 14.e5 c5! 15.e6 cxd4 16.Bxd4 Rg8 17.exd7+ Rxd7 is equal.
    • After 14...Nd5 15.Nxd5 cxd5 16.e6 Be8 17.Ne2 c5 18.c3 White's passer give him the advantage.
  • After 14.Nb3 b6 15.Bd4 Rh7 16.Bf6 fxe4 17.Nxe4 gives White more activity and better pawn structure.

12...Nxf5 13.Nxf5

  • 13.Ne4 Nxe3 14.Kxe3 Bd6 15.Rad1 Rhe8 remains equal.

13...Bxf5 14.Rac1 Be7 15.Ne2

  • If 15.Ne4 Bxe4 16.fxe4 then Black exploits the isolated e-pawn by 16...Bf6 17.Rb1 Rde8.

15...c5 16.Ng3 Bg6 17.c3 b6 18.Rcd1 Bf7

  • 18...Bh4 19.Rhe1 Bf7 20.b3 c4 21.b4 Rd3 22.Bd4 remains equal.

19.Rxd8+ Rxd8 20.Ra1?!

  • 20.a4 a5 then:
    • After 21.h4 Be8 22.Bg5 Bxg5 23.hxg5 Rd2+ 24.Kg1 Bg6 Black must win a pawn.
    • 21.Re1 Bh4 22.Bc1 Re8 23.Re4 Rxe4 24.fxe4 Bg6 leaves Black threatening White's passed pawn, which has no protection.

20...Bh4 21.Bf4 Kb7 22.Kg1 Re8!?

  • This allows White's rejoinder, blocking the e-file to the Black Rook and placing the Knight on a splendid outpost.
  • Black maintains a small advatage after 22...g5 23.Be3 Bxg3 24.hxg3 h6 25.f4 g4.

23.Ne4!

  • White has equalized.

23...Bd5 24.g3 Bd8 25.Re1 Kc6

  • Black's ambition now is defensive: bring the King to d7 to protect the Rook.
  • 25...Bf7 26.Kf2 Kc6 27.b3 b5 28.h4 remains equal.

26.a3 g5 27.Bd2 g4 28.Kf2 gxf3

  • 28...Kd7 29.Bh6 c6 30.Bf4 a5 31.h3 gxf3 32.Kxf3 remains equal.

29.Ng5?!

  • Perhaps Black was hoping for Black to reply 29...Bxg5 30.Bxg5 31.Rxe1 Kxe1 when White goes to the ending with Bishops of opposite color and good chances to draw.
  • 29.Kxf3 Kd7 30.Bh6 c6 31.g4 c4 32.Bf4 Bh4 remains equal.

33...Kc4 34.Kd1

    • After 35...Bb7 36.Bc3 a5 37.Nf4 a4 gives White the active King.

      • If 40.Kb1 then after 40...axb2 41.Bd4 Bg8 42.Ne4 Bh7 Black mates on the next move.

36...a5 37.Be3 c4 38.h4

  • If 38.g4 hxg4 39.Nxg4 Bh4 40.Kb1 Be4+ then:
    • 41.Kc1 Bf5 42.Nh6 f2 43.Bxf2 Bg5+ wins for Black.
    • If 41.Ka1 a4 42.Bc5 Bf5 then:

    • If 16.Bc1 Ncb4 17.Bxc4 0-0 then:

WHITE: Zahar Efimenko
Position after 14...Nc6e7


15.e5!

  • White closes the Bishop's best escape route; the Knight on g4 (remember him?) has nowhere to run.

15...Bb6

  • If 15...Bxe5 then after 16.hxg4 Bf4 17.g5 h4 18.Bb2 h3 19.Rfc1 White is threatening 20.Bxg7! with a double attack on the Rook at h8 and the Queen.

WHITE: Zahar Efimenko
Position after 21...Qd8d7:B


22.Qe7+!

  • White forces an exchange of Queens, further progress for the pawn and, just for good measure, wins the Knight at g4.

22...Qxe7 23.dxe7+ Kf7

  • If 23...Ke8 24.hxg4 hxg4 25.Nd2 then:
    • 25...g3 26.Ne4 gxf2+ 27.Nxf2 White is still a piece to the good.
    • After 25...Rh5 26.Ne4 Bc7 (threatening perpetual check) 27.Rfd1! White remains up a piece.

24.hxg4

  • White's play is so dominant that he was able to force Black to leave the Bishop en prise fo 13 moves before finally taking it.

24...hxg4 25.Nd2 g3 26.Nc4 Rh5

  • If 26...gxf2+ then after 27.Rxf2 Bxf2+ 28.Kxf2 Ke6 29.Re1+ Kd7 30.Nd6 White threatens to win another pawn.
  • If 26...Bd4 27.Nd6+ then:

29.Kxf2 Rd5 30.Re1 Ke8 31.Rc3 Kf7 1-0

  • Black's last move is deadful, but he has no defense in any event.
  • If now 32.e8Q+ Rxe8 33.Rc7+ Kg6 34.Rxe8 then White has a prohibitive material advantage.
  • Alexander Sergeyevich resigns without waiting for Grandmaster Efimenko to reply.

  • 14...Rd8 15.c4 bxc4 16.Bxc4 Ngf6 17.Bh6 Nxb6 18.axb6 Qxb6 19.Na5 Bc8 20.Be3 soon brings victory to White (Rasmussen-Glud, Danish Ch, Aalborg, 2007).

15.axb6 Qxb6 16.Na5 Bc8 17.c4 b4 18.Be3!?

  • 18.e5 Bd7 19.Be3 Qc7 20.Bd4 f6 is equal (Vocaturo-Neimer, World Jr Ch, Gaziantep, 2008).

18...Qc7

  • Black has an extra pawn, but White has more space and activity. The game is unclear.
  • 18...Qb8?! 19.e5 d5 20.Nc6 Qb7 21.cxd5 exd5 22.Rfc1 gives White more than enough space and activity to make up for the pawn.

19.f4?!

  • White grabs some space, but better is to treaten a loose pawn.
  • If 19.Bd2 Rb8 20.Ra4 b3 21.Ra3 d5 22.Rxb3 then:
    • 22...dxe4 23.Bxe4 Rxb3 24.Nxb3 Bd6 25.h3 gives White the advantage in space.
    • If 22...Rxb3 23.Nxb3 dxe4 then:
      • 24.Qxe4?! Nf6 25.Qe3 Ng4 26.Qh3 is equal.
      • 24.Bxe4 transposes into the main line.

19...Bd7 20.e5 Nh6?!

  • Fritz says that Black has equalized, but the Knight at this place soon becomes a liability.
  • 20...dxe5 21.fxe5 f6 22.c5 Bxc5 23.exf6 Kf7 24.Kh1 give White a more active game in compensation for the pawn.

21.g4 dxe5 22.fxe5 Bc5

  • White still has more freedom as long as Black's Knight is offsided and immobile.
  • 22...g5 23.Bd4 Bc5 24.Bxc5 Qxc5+ 25.Rf2 then:
    • 25...Ra7 26.Nb3 is equal. This game might continue 26...Qc7 27.Bc2 Ng8 28.Qe3 Ne7 when Black can finally bring her Knight around to the queenside where it have some room to breathe.
    • As badly as it seems to need it, Black cannot redeploy her Bishop with 25...Ng8? because of 26.Qf3!.

23.Bxc5 Qxc5+ 24.Kh1

  • White still has the advantage in mobility.
  • 24.Rf2 0-0 25.Nb3 Qc7 26.Qe4 then:
    • 26...Bc6 27.Qf4 Rfd8 28.Bc2 Kg7 brings Black closer to equality since her Knight now has an open route to the queenside.
    • 26...Kg7 27.Qf4 Ng8 28.g5 a5 29.Be4 Ra7 is equal.

24...0-0 25.h3 Kg7!

26.Qe4 Rac8

  • 26...Qe7 27.Nb3 Rfc8 28.Qe3 Bc6+ remains equal.

27.Kh2 Qc7

  • 27...f5 28.exf6+ Rxf6 29.Rxf6 Kxf6 30.Qf4+ Kg7 31.Nb3 Qc6 remains equal.

WHITE: Hulkar Tokhirjanova
Position after 29...Qc7b8


30.Nb3!

  • White has the initiative. She plans to use it to exploit Black's weak queenside pawns.
  • If 30.Rfd1 Bc6 31.Bf1 then:
    • 31...Ba8 32.Rd6 Qa7 33.Nb3 Qb7 34.Kg3 gives Black an extra pawn, but White is more active.

      • After 33.Nxc6! Nxc6 34.Bg2 Qc5 35.Bxc6 Rxc6 36.Rxa6 Rxa6 37.Rxa6 White is more active.
      • 33.Bd3?! Kg8 34.Qd4 Qxd4 35.Rxd4 Rc7 36.Kg3 Kg7 37.Rd6 is equal.

30...Rc6

  • 30...Qb7 31.Ra5 Bc6 32.Rfa1 Rfd8 33.Be2 Ra8 34.Nc5 White enjoys the initiative.

31.c5

  • Also good is 31.Be2 h6 32.gxh6+ Nxh6 33.c5 Nf5 34.Bf3 when White still has the initiative.

31...Qc8?!

  • 31...Ne7 32.Bxa6 Nd5 33.Qg3 Rxa6 34.Rxa6 Bb5 is equal.

32.Qxb4?!

  • 32.Ra5! would be a better way to exploit the dispersion of Black's pawns: 32...Qb7? fals against 33.Be4 Qc8 34.Bxc6 Bxc6 35.Rfa1.

32...Ne7 33.Be4

  • 33.Qd4 Nf5 34.Bxf5 gxf5 35.Rac1 Rc7 36.Qh4 Rb7 nets Black a pawn.

33...Nd5 34.Qd4

  • White's Queen is trying to keep all her central pawns overprotected, which raises the possibility that it may become overloaded.
  • If 34.Qe1 Qc7 35.Qg3 Bc8 36.Rfd1 then:
    • 36...Qb8 37.Ra4 Rh8 38.Rc4 Rc7 39.Bxd5 exd5 40.Rc3 maintains White's advantage.
    • 36...Rh8 37.Rxd5 exd5 38.Bxd5 h6 (the Rook has nowhere to go) 39.Bxc6 Qxc6 gives White an extra pawn.
  • Also good is 34.Bxd5 exd5 35.Qc3 Qc7 36.Rf6 Rb8 37.Rd6 giving WHite more freedom.

34...Kg8

  • 34...Qc7 then:
    • 35.Kg1 Bc8 36.Rf2 Qe7 37.Rf6 Rc7 38.Bxd5 Rd7 39.Raf1 gives White pressure on the kingside.
    • If 35.Kg2?! Bc8 then:
      • 36.Bxd5 exd5 37.e6+ Kg8 38.exf7+ Rxf7 is equal.
      • 36.Rf3 Rd8 37.Kh1 Kg8 38.Raf1 Rd7 39.Bxd5 exd5 is equal.

35.Rfc1 Qd8 36.Qd2 Qb8 37.Bxd5!

  • White does well to initiate the exchange.
  • 37.Bc2? Qxe5+ 38.Kh1 f6 39.gxf6 Qxb2 40.Ra5 Qxf6 gives Black two extra pawns.

37...Qxe5+!?

  • Black's plan is also to keep pieces in the center.
  • Because of the inaccurate play by White that follows, this ends up giving Black two extra pawns.
  • 37...exd5?! 38.Nd4 Qxe5+ 39.Kg2 Rcc8 40.Rxa6 gives White two passed pawns and more activity.

38.Kg1?

  • White snatches defeat from the jaws of victory.
  • This move directly cedes a pawn to Black.
  • 38.Kg2 defends the h-pawn better; if 38...exd5 then after 39.Nd4 Rc7 40.Rxa6 Rb8 41.b3 White remains better.

40.Kh1 Qxh3+

  • Black now has two extra pawns.
  • 41.Re1 Qxh3+ 42.Qh2 Rxc5 43.Qxh3 Bxh3 also gives Black two extra pawns.

41.Qh2 Qe3 42.Qh4

  • For White, this move takes the patient from critical to terminal..
  • If 42.Nxc6 Bxc6 43.Qg2 f6 then:
    • 44.b4 fxg5 45.Rf1 Rxf1+ 46.Rxf1 Kg7 gives Black a material edge and more activity.
    • 44.Re1 Qxc5 45.Rac1 Qd6 46.Rf1 a5 gives Black a theoreticla one-pawn advantage.

44...Qd8 45.c6 Bc8 46.Rf3 h5

  • After 46...Re7 47.Rxe7 Qxe7 48.Qf4 Re8 Black's two extra pawns continue to be an advantage.

47.Qf4 Bg4

  • Perhaps stronger is 47...Re7 48.Rfe3 Rxe3 49.Rxe3 Qb6 50.b3 Qc5.

48.Rfe3

  • If 48.Ra3 then after 48...f6 49.Re6 Rcf7 50.Rxf6 Rxf6 51.gxf6 Rxf6 Black remains up by two pawns./li]

48...Qc8 49.Re5

  • In her haste to regain lost material, White makes White's task easier.
  • Better is 49.Qd6 Qb8 50.Qe5 Rd8 51.Qf6 Rdc8 52.b3 Rf8 when Black still has two extra pawns, but has difficulty taking advantage of them.

Position after 49.Re3e5


49...Rxc6!!

  • The sacrifice is stronger than 49...Qb8 50.Qd2 Rcc8 51.b3 Rfe8 52.c7 Qa8 when Black continues to piddle about with three pawns for a piece.

50.Nxc6 Qxc6

  • With an asymmetrical material balance, Black has a theoretical one-pawn advantage.

51.Qd4 Rc8

  • 51...Bf3+ 52.Kg1 Qc2 53.Qf2 Qxf2+ 54.Kxf2 Be4 cuts the line of communication between White's Rooks.

52.R5e3

  • This assures that the line of communication is not broken, but it further pacifies White's position.
  • Black is still better after 52.Re7 Bf3+ 53.Kg1 Be4 54.Qf2 Rf8.

52...Qd7!

  • The text is stronger than 52...Be6 53.b3 h4 54.R1e2 h3.

53.Re7 Bf3+ 54.Kh2 Qd6+ 55.Qe5 Qxe5+

  • Also good is 55...Qb4 56.Re8+ Rxe8 57.Qxe8+ Kg7 58.Qe5+ Kh7.

56.R1xe5 Rc2+ 57.Kg3 Be4 58.Ra7

    • If 61.Kh3 Bf5+ 62.Kxh4 Rc3 63.Rxf5 Rc4+ 64.Kg3 gxf5 leaves Black two pawns up.
    • After 61.Kg1 h3 there is no way to stop the h-pawn.

9. Update (Monday): Hou Yifan named Grandmaster
Hou Yifan became the youngest lady ever to earn the title of international grandmaster, a title once reserved for men, when the honor was conferred upon her by FIDE at the meeting of the federation's general assembly in Dresden in late November.



Hou Yifan
Photo: First Saturday (Hungary)

Her accomplishments this year include first place in a strong women's tournament in Istanbul in March, third place in the World Junior Championships in Turkey in July (where she played in the "boys'" event), runner-up in the women's world championship tournament in Nalchik in September and a bronze medal for individual performance on the top board at the Dresden Olympiad in November.

The young lady turns 15 next February 27. She is currently third among all women on the official rankings behind Koneru Humpy of India and Judit Polgar of Hungary.

10. Update (Tuesday): Mickey Adams "apparently" withdraws from Grand Prix
The website Chessdom.com reports today that British grandmaster Mickey Adams will not participate in the next leg of the FIDE Grand Prix in Elista starting next week, speculating that Adams has withdrawn from the Grand Prix altogether.

If it is true that Adams has withdrawn, then the Cornish grandmaster joins a growing list of top ranked chess players in revolt against FIDE and its President, Kirsan Ilyumzhinov, for the arrogant and high-handed manner in which the world championship cycle was modified with the cycle in progress. Grandmasters Alexei Shirov of Spain and Levon Aronian of Armenia have spoken out against the FIDE's latest action and 18-year-old Norwegian grandmaster Magnus Carlsen has withdrawn from the Grand Prix in protest.
