The JR Chess Report (August 23): Chuckie Takes Jermuk
Chuckie wins Jermuk Grand Prix

Ukraininan grandmaster Vassily Ivanchuk, known to his many, many fans as "Chuckie", scored 8 points in 13 rounds to take first place in the fifth leg of the FIDE Grand Prix completed just hours ago in the health resort Mecca of Jermuk, Armenia.

Vassily Mikhailovich spent most of the tournament tied for the lead with Hungarian grandmaster Peter Leko and Rustam Kasimdzhanov of Uzbekistan. For Kasidzhanov, it was his most impressive finish in an elite grandmaster tournament since being prematurely raised to that level of competition by winning the 2003 FIDE Knock Out Tournament in Tripoli, Libya, the last Knock Out tournament on which FIDE foolishly insisted calling the winner world champion.

When the final round started today, six out fourteen players still had a shot at winning or sharing first prize with Leko and Ivanchuk sharing the lead with 7 points each. Chuckie, playing Black, defeated Armenian GM Vladimir Akipian in 62 moves to assure himself at least a share of the tournament title, while Leko lost to Israeli GM Boris Gelfand in 78 moves. Gelfand, with 8 points, finshed tied with Armenia's Levon Aronian, who beat Russian GM Ernesto Inarkiev today. Leko, with 7 points, finished tied for fourth with Kasimdzhanov and former Russian national champion Evgeny Alekseev, both of whom played draws today.

Old Timers Short, Timman and Korchnoi Shine in Staunton Memorial

Former world championship challenger Nigel Short, 44, rejoined the 2700 club after an absence of many years by scoring 8 points in ten rounds in the Scheveningen team match while Jan Timman, 57, also a former world title competitor, won the round robin competition in which Viktor Korchnoi, 78, who nearly won the world championship from Anatoly Karpov 31 years ago, finshed a strong third at the seventh annual Howard Stauton Tournament with finished in London at the historic chess haunt Simpson's Divan Monday.

In the round robin event, Mh. Timman scored 7 points in nine rounds while Viktor Lvovich scored 6. Russian grandmaster Alexander Cherniaev was second with 6 points. Timman won 6 games and lost one, that to Viktor Lvovich.

In the ten-round-by-five-board Scheveningen team match, the British players, led by Short, defeated a Dutch team led by national champion Jan Smeets, 26-23. Mr. Short's dominance in this event is demonstrated by the fact that the British team won with Mr. Short being its only player to score better than 50%.

Viktor Lvovich Korchnoi was born in Leningrad, the once and future St. Petersburg, on March 23, 1931. He was in the world championship cycle by the late fifties and was four times Soviet Champion. In 1974, he narrowly lost the final candidates' match to Karpov, who went on to take the title when then-champion Bobby Fischer defaulted in a dispute with FIDE over conditions for the title match. Viktor Lvovich defected to the West in 1976, finally settling in Switzerland. Although still stateless in 1978, he won the right to challenge Karpov for the world title. The match was held in Baguio City in the Philippines and was won by Karpov, 6 wins to 5 with draws not counting, in 32 games. Korchnoi also played Karpov for the world title in 1981, but was soundly beaten by Karpov in a match held in Merano, Italy. Viktor Lvovich is considered one of the greatest players never to win the world championship. Since 1996, he has earned the reputation of being the greatest senior citizen player of all time.

Keti Arakhamia-Grant Takes Baltic Queen Crown

Grandmaster Ketevan Arakahmia-Grant of Scotland by way of Georgia won the Baltic Queen Women's Tournament in St. Petersburg Thursday with 6 points in nine rounds.

International master Ekaterina Atalik of Turkey by way of Russia, who led much of the way until faletering in the final rounds, finished second with 5 points. Grandmaster Pia Cramling of Sweeden, German IM ELisabeth Phtz and IM Viktorija Cmilyte of Lithuania tied for third with 5 points each.

Ms. Arakhamia-Grant started the tournament badly, scoring only 1 points in the first four rounds. She then won her next four game, culminating with an eighth round win over Mrs. Atalik to secure the tournament title.

Ms. Arakhamia-Grant became a full grandmaster earlier this year and switched her federation from her native Georgia to Scotland. She has lived in Edinburgh since her marriage to grandmaster Jonathan Grant in 1996. The couple have one child. Ms. Arakahmia-Grant was the overall Scottish national champion in 2003 and runner up in the British national championship in 2006.

Four Share First Prize in Acropolis Open

Four players shared the top honors in the Acropolis Open completed Tuesday in Chalkida, about 30 miles from Athens.

Borki Predojevic (Bosnia), Hristos Banikas (Greece), Ioannis Papaioannou (Greece) and Atanas Kolev (Bulgaria) scored 6 points each in nine rounds. Predojevich is first among equals with the superior tiebreak score.

The tournament got off to a tragic start when Greek master Nikolaos Karapanos suffered a heart attack while planning his final moves against Dan Zoler of Israel in the first round. Zoler, a doctor, immediately jumped into action in an attempt to revive Karapanos, but to no avail. Karapanos was taken to a hospital where he was pronouced dead.

Dr. Zoler, who was in a completely lost position, resigned the game and, understandably shaken, withdrew from the tournament.

One hundred players started the event.

3. Jakovenko - Inarkiev, Round 11
Rather than provide an important game or two for Jermuk this week, my staff* and I have decided to provide one good game between two players who had no chance at first prize by the end of the tournament and provide some late-round games critical to the prizes next week.

  • Also good is 26...dxe5! 27.d6+ Qxd6 28.Qxd6+ Kxd6 29.Rxb6+ Kc7 when Black has an extra pawn.

27.Nxg6+ Kd8

  • 27...fxg6?! 28.Bxe4! Rh8+ 29.Kg1 Be5 30.f4 Bc3 31.Rb1 is equal.

  • White misses his best chance in the game.
  • If 32.Kg2! c2 33.Rb2 Rd3 then:
    • If 34.Rh3! Qd7 35.Qe4 then:
      • 35...Rxe3 36.Bxe3 Bxb2 37.Rh7 Qxh7 38.Bb6+! wins for White.

32...Qe7 33.Ba3?

WHITE: Dmitry Jakovenko
Position after 33.Bc1a3


  • The strongest move is 33...c2! 34.Rxb7 Qxb7 35.Rh8+ Ke7 when:
    • 36.Nf5+ Kd7 37.Rxa8 Rd1+ 38.Kg2 Qxa8 gives Black the exchange.
    • If 36.Rxa8 then after 36...Qxa8 37.Nxc2 Rxd5 Black wins the exchange.


  • White misses the saving grace and leaves three pieces unprotected.
  • 34.Kg1! Rf8 35.Qe2 Rd2 36.Qc4+ Kd8 37.Qb4 is equal.

34...Ra4 35.Rb3?

  • This puts pressure on the pawn, but neither the Rook nor the Queen is going to take while it is defended by the Bishop.
  • Correct is 35.Bb4! Rf8 when:
    • 36.Qd1 Rxa2 37.Qb3 c2 38.Rc1 Qg5 39.Bxd6+ is equal.
    • If 36.Qd3 Rxf2 37.Bxc3 Rxg4 38.Rh7 Rgxg2 39.Rxg7 is equal.


  • White misses the best move, but it won't cost him as much this time.
  • 35...Rf8! 36.Qd1 Ra5 37.Re3 Qd7 38.Qe1 Kd8 exhausts the last of White's initiative while Black is ready for attack.

36.Rh7 Kb8!

  • 36...Rh8? then:
    • 37.Rxc3+! Kd8 38.Rxh8+ Bxh8 39.Rb3 Be5 40.Kg1 is equal.
    • If 37.Rxh8?! Bxh8 38.Kg1 Bc8 39.Ne3 Bd4 gives Black the more active game.


  • If 37.Qe3 Qxe3 38.Nxe3 Rh8 39.Rxh8+ Bxh8 then:
    • 40.Kg2 Kc8 41.Bxd6 Rxa2 42.Rb4 Rd2 43.Bf4 Rd4 Black is better owing to the superiority of his Bishop pair.
    • If 40.Kg1 Bd4 41.Nc2 Be5 42.Ne3 Ka7 leaves Black's position well defended and his c-pawn ready to advance.

37...Rxa2 38.Nf4 Ra1!

  • The Bishop is toast. So is White.

39.Kg2 Rxc1 40.Ne6 c2 41.Rxg7

WHITE: Dmitry Jakovenko
Position after 41.Rh7g7:B


  • The Queen sacrifice puts the Knight too far away from the passed pawn to make any difference.
  • The text wins faster than 41...Rg1+ 42.Kxg1 c1Q+ 43.Kg2 Qxg7 44.Nxg7.

42.Nxg7 Rb1! 0-1

  • After the pawn queens at c1 and the Rooks are exchanged, Black will be a Rook to the good.
  • Dmitry Vladimirovich resigns.

WHITE: Jan Timman
Position after 31...Re8b8


  • Here the best move was in order.
  • If 32.g3 a5 33.Bd2 h4 34.Qxb7 Rxb7 then:
    • 35.g4! Bd4 36.Rc4 gives White the initiative.
    • 35.Bxa5!? hxg3 36.Bc3 Rc7 37.Bb2 Rxc1+ 38.Bxc1 White has the advantage of the remote passer.

32...Kg7 33.Qxb7

  • If 33.Qc4 Kg8 then:
    • 34.Bf4 Bxf4 35.Qxf4 Rc8 36.Rd1 remains equal.
    • 34.Bd4 Bf4 35.Re1 Bd2 36.Rd1 Bg5 remains equal.

33...Rxb7 34.Rc6!

  • White has better chances attacking the unprotected pawn than the unprotected Bishop.
  • 34.Rc5 Bc7 35.Ke2 Kf8 36.g4 hxg4 37.hxg4 Ke7 remains equal.

34...a5 35.Rc5!?

  • This looks like the correct follow up to White's last move, but it isn't/
  • Correct is 35.Bd2! Ra7 36.Rc5 Bc7 37.Bc3+ when:
    • 37...f6 38.g4 hxg4 39.hxg4 Kf7 40.Kg2 Bb6 41.Rb5 gives White teh more active game.
    • 37...Kf8 38.g4 hxg4 39.hxg4 Ke7 40.g5 gives White more freedom; Black is almost out of reserve pawn tempi.

35...Bc7 36.Ke2 Kf6 37.Rb5!?

  • The game is again equal.
  • 37.Bd2 Ra7 38.Bc3+ Ke6 39.g4 hxg4 40.hxg4 gives White more freedom.

37...Rxb5 38.axb5 Ke6 39.Kd3 Kd5?

  • Black's King can get no closer to the queenside, but White's King has nothing stopping it.

40...f5 41.Kb3 f4 42.Ba7

  • 42.Bd2 Bb6 43.Bxf4 Bxf2 44.Bc7 leaves the a-pawn fried.

  • If 44...Be1 45.f3 Kd6 46.Bxa5 then:
    • 46...Bh4 47.Bd2 g5 48.Ka5 Bf2 49.Ka6 wins for White, as it will cost Black the Bishop to stop the pawn.

  • Black could have resigned after seeing this move. He must either lose the Bishop or allow the pawn to queen.


  • 49...Be3 50.Bxe3+ Kxe3 51.b7 is clearly hopeless.

50.Kxb6 h4 51.Bg5!

  • Zugzwang!


  • If 51...Kg3 then after 52.f4 Kxg2 53.Bxh4 Kxh3 54.Bg5 the White King takes the remaining Black pawn.

52.Bxh4 g5 53.Bxg5 1-0

  • Black takes one pawn while White queens the other.

6.Nxd4 Bd7 7.Nxc6 bxc6

  • If 7...Bxc6 8.Bxc6+ bxc6 9.c4 then:

10.Nf3 dxe4 11.Bxe4!?

  • 11.Qxe4 Nf6 12.Qh4 h6 13.0-0 Rb8 14.Bd2 Nd5 15.c4 Nf4 16.c5 Nxd3 17.cxd6 Qxd6 18.Rad1 Rb5 19.Bc3 0-0 20.Be5 Qd5 21.Bxg7 Kxg7 22.Ne1 Qg5 23.Qd4+ e5 24.Qxd3 is equal (Yakovich-Shulman, Op, Vladivostok, 1994).

WHITE: Jan Timman
Position after 18.h2h3


  • Black goes into a line that involves a speculative exchange sacrifice.
  • If 18...e5 19.Ba5 Qxa5 20.Rxd6 then:
    • 20...Qxa2 21.Red1 Be8 22.Qc4 Qa3 23.R6d5 Rc8 remains equal.
    • 20...Re8!? 21.Red1 Be6 22.a4 c4 23.Nd4 exd4 24.Rxe6 gives White a tactical edge.

19.Bf4 e5

  • The pawn advance is part of Black's plan. He's going to have the two Bishops and wants an open center for them in compensation for sacrificed material.

20.Nxe5 fxe5 21.Bxe5 Qc8 22.Bxb8 Qxb8

  • The material advantage gained by White is not as palpable as it would be in a closed center. Black's two Bishops are nearly equal to White's Rook and two pawns.

23.Re2 Qb6 24.a4 Qa6 25.c4

  • If 25.Red2 Bf5 26.Qe8 Qg6 27.Rd6 then:
    • 27...Qh5 28.R1d2 Qg5 29.Qd8 Qf4 30.Ra6 is equal.
    • 27...Qg5 28.R6d5 Qg6 29.Rd6 Qg5 30.R6d5 draws.

25...h6 26.Re3 Bc6!?

  • Black exposes his back rank to White's Rook at d1.
  • Better is 26...Qf6 27.Rf3 Bf5 28.Qd5 when:
    • 28...Qg6 29.Re1 Bd7 30.Rxf7 Qxf7 31.a5 gives White a modest material advantage.
    • 28...Qe6? 29.Qxe6 Bxe6 30.Rxf7 Kxf7 31.Rd8 gives White excellent winning prospects.

27.Qe6 Qb7 28.Rd8 Kh7 29.Qc8 Qxc8 30.Rxc8 Bb7?!

  • Black "forces" White to move the Rook to a better file.
  • If 30...Rf6 then after 31.h4 h5 32.a5 a6 33.Re2 Bd7 34.Rd8 White still has a theoretical material edge and the initiative.

31.Rd8 Bc6 32.a5

  • 32.Re6!? Bd7 33.Ra6 Bf5 34.Ra8 Bc2 35.Rb8 g5 is equal.

32...Be7 33.Rc8 Bh4 34.g3

  • 34.Rxc6? Bxf2+ 35.Kf1 Bxe3+ 36.Ke2 Bd4 wins for Black.


  • 34...Bg5? 35.Rxc6 Bxe3 36.fxe3 Rf3 leaves White two pawns to the good.

35.Rxc5 Bf6 36.Rd3 Re7 37.f3?!

  • White weakens his kingside.
  • Better is 37.f4 Be4 38.Rd6 Bc2 when:
    • 39.Rb5! Re3 40.Kf2 Rxb3 41.Rxb3 Bxb3 42.c5 White continues to enjoy a material advantage.
    • If 39.b4?! Bc3 40.Rdd5 Bxb4 41.Rb5 Bc3 then:
      • 42.c5 Ba4 43.Rb1 Bxa5 is equal.
      • 42.a6!? Re6 43.c5 Rxa6 44.Kf2 Be4 gives Black the initiative..

WHITE: Jan Timman
Position after 37.f2f3


  • Black takes full advantage of the weakness and takes the f-pawn.


  • 38.Rxf3? Bd4+ 39.Kg2 Bxc5 is a huge mistake.


  • The game is equal.

39.Rcd8 Re1+ 40.Kf2 Ra1

remains equal. 40...Bxd8 41.Kxe1 Bxa5+ 42.Ke2 Bb6 43.b4 remains equal.
41.R8d7 Be4 42.R3d6

  • 42.Re3 Ra2+ 43.Ke1 Bc6 44.Rxa7 Bd4 remains equal.

42...Bc3 43.Rxa7

  • 43.g4 Rxa5 44.Re6 Bc2 45.Re3 Bb4 then:
    • 46.Rf3 Ra3 47.Rff7 Bc3 48.c5 Bxb3 gives Black the initiative.
    • 46.Kf3 Ra3 47.Rd5 a5 48.c5 Bxb3 gives Black the initiative.


  • White takes advantage of the pin to attack the Rook.


  • Now White misses the opportunity to force a draw.
  • If 44.Rdd7? Bc5+ 45.Ke2 Ra2+ then:
    • 46.Kf1 Bxa7 47.Rxa7 Bc2 48.c5 Bxb3 gives Black enough time to stop the c-pawn.
    • 46.Ke1 Bb4+ 47.Kd1 Rg2 48.Kc1 Rxg3 gives Black a strong position.
  • 44.Ke3! Re1+ 45.Kf2 Ra1 46.Ke3 Re1+ draws.

44...Bxd6 45.Rxd6 Rxa5

  • Black has the material advantage.

46.Ke3 Bg2 47.h4 Rf5 48.b4?

  • This move costs White his kingside pawns.
  • If 48.Rd3! then Black will have to take more time to take the pawns, e.g., 48...Kg6 49.b4 Rf3+ 50.Kd4 Rxd3+ 51.Kxd3 Kh5, giving White time to advance his queenside.

    • 50...Rf2+ 51.Ke3 Rf3+ 52.Kd2 Rf2+ 53.Kc3 is equal.


  • 49.Ke2 Rxg3 50.Kf2 Rg4 gives Black the material advantage.


  • That's one pawn.


  • 50.Kc5 Rg4 51.Rd4 Rxd4 52.Kxd4 Kg6 53.b5 Kh5 wins the h-pawn.

50...Rg4+ 51.Kc5 Rxh4

  • That's the second pawn.

52.b6 Bb7

  • Black misses a faster win.
  • If 52...h5! 53.Rd2 then:
    • 53...Bb7! 54.Rd3 Re4 55.Rd7 Ba6 wins for Black.
    • 53...Be4!? 54.Kd6 g5 55.Rd4 Rf4 56.Ke5 Bg2 57.Rxf4 gives a pawn back to White.

53.Kb5 Rh1 54.c5 Rb1+ 55.Ka5

  • If 55.Ka4 Ba6 56.Rd4 h5 57.Ka5 then:
    • 57...Be2 58.Re4 Bf3 59.Rh4 Kg6 wins for Black.
    • If 57...Bf1!? 58.Rd5 Rb5+ then:
      • 59.Ka4 Kg6 60.Rd6+ Kg5 61.c6 Rxb6 62.c7 Rxd6 63.c8Q gives White some counterplay, but Black should still win.
      • If 59.Ka6 then 59...Rxc5+! wins immediately.

55...Ra1+ 56.Kb4 Rc1 57.Kb5 Bg2 58.Rd2

  • White puts up a more stubborn defense after 58.c6 Bf1+ 59.Ka4 Ra1+ 60.Kb4 Rb1+ 61.Ka3 Rxb6.

58...Rb1+ 59.Kc4 Bh1 0-1

  • White can make no further progress with his pawns.
  • Mh. Timman resigns.
