Grand Slam Final Begins in Bilbao



The Grnad Slam Final Tournament began in Bilbao, Spian, today with three of the four winners of designated qualifying tournaments and Aremian grandmaster Levon Aronian, who took the place of Nanjing winner Veselin Topalov after Topalov withdrew from the event.

The other three competitors are Alexander Grischuk, who won this year's Linares International Tournament in March; Sergey Karjakin, now designated a Russian grandmaster, who won the Corus Tournament in Wijk aan Zee in January; and Alexei Shirov, playing in his adopted home country, who won the MTel Masters' Tournament in Sofia in May.

In today's first round action, Grischuck defeated Aronian in 52 moves while Karjakin and Shirov fought 25 moves to a draw.

The quadragular tournament consists of six rounds and ends Saturday.



Old Timers Defeat Youth for First Time



The Experience team scored its first victory in the three-year-old team match series against Rising Stars today in Amsterdam as the latest edition of the event ended in a 27½-22½ win for the old timers.

Not-so-old old timers Peter Heine Nielsen (36) and Peter Svidler (33) were the top scorers for the Experience team with 6½ and 6 points respectively.

Jan Smeets, the reigning Dutch national champion, was the only Rising Star to score better than 50% in the ten round match. Smeets had 6 points out of a possible 10. As the leading scorer on the Rising Stars, Smeets will compete in next Spring's Melody Amber Rapid/Blindfold Tournament in Nice, France. The past winners of the ticket to Nice from Amsterdam were Magnus Carlsen in 2007 and Sergey Karjakin in 2008.

1. Drunk grandmaster checkmated after dozing off
CHENNAI, India (Reuters) - A leading French chess player turned up drunk and dozed off after just 11 moves in an international tournament in Kolkata, losing the round on technical grounds, domestic media reported Friday.

Grandmaster Vladislav Tkachiev arrived for Thursday's match against India's Praveen Kumar in such an inebriated state that he could hardly sit in his chair and soon fell asleep, resting his head on the table, Hindustan Times newspaper reported.

Indian papers carried pictures of the world number 58 sleeping and the organizers' futile attempts to wake his up.

The game was awarded to the Indian on the technical ground of Tkachiev being unable to complete his moves within the stipulated time of an hour and 30 minutes, the paper said.

6. I know
It is the Reuter's headline so I guess it makes for a good headline. From reading the article it's clear it was forfeit but Reuter's wrote the headline, not me.

22. Here's a little more about it
. . . from ChessBase.

Tkachiev has been in trouble like this over his drinking before. He likes life in the fast lane. Unfortunately, drinking goes that territory.

That's really too bad. He's a good player.

Mikhail Tal's drinking was legendary. There are two big difference between Tkachiev and Tal. First, Tal was in poor health his enire life and knew from his yout he wasn't likely to live to be an old man. Tal embraced life because he knew he wouldn't time to live, so he lived while he had the time. He was once asked about correspondence chess. He replied: I drink, I smoke, I gamble and I chase girls, but correspondence chess is a vice I've never acquired.

The second big difference is that Tal was a functioning drunk. After a night of drinking, a friend had to get Tal to a morning game. He could hardly walk. But he won the game.

26. Further Note:
Tkachiev has scored 3½ points in 6 rounds (as of today) in Kolkata. I would wager that the forfeited game is his only loss.

Incidently, he was playing an opponent he would be expected to beat. Had he done so, he would be within striking distance of first place.

I don't know what the prize money is like in Kolkata, but it sounds like Tkachiev took a pretty expensive drink. I hope it was good stuff.

Incidently, according to a friend of his, Tkachiev won the French national championship last month after going dry for three months. He won by a half-point over defending champion Maxime Vachier Lagrave.

24. Chess is so boring the players are falling asleep now.
That's a first. I can see soccer players falling asleep, but I guess chess makes sense also.

The poor guy was hungover, I guess. I'd probably start drinking too if I woke up one morning and realized chess was my whole life.;)

25. Hey, it's just another example of substance abuse in sports
!!

Besides, in Tkachiev's case, chess isn't his whole life. There's also the women. Lots of women.

20.Kg2!

Position after 32.Nh2g4


32...Be4!?

  • Black is on the vege of winning, but now begins to make some inferior move that cost him first the victory and then the game.
  • If 32...Bd5 33.Rg5 Nf7 34.Rf5 Be6 35.Rxf7 Bxf7 36.h6 g6 37.Qf3 Bd5 38.Qe2 Bb7 leaves Black an exchange to the good.

  • Again Black balks at putting the game away.
  • 37...Nxb2 38.Rb1 Qc4 39.Rxb2 Qe2 40.cxb4 Qxe1+ would just about finish Black.

38.cxb4 Ne5

  • 38...Rd6 39.Rc1 Qd7 40.f3 exf3 41.Bc3 f2+ maintains Black's advantage, but it is no longer a winning advantage.

39.Nxe5 Rxe5 40.Qxc8?!

  • After getting back in the game, White tries to give it back to Black again.

42...fxe3 43.Bc3 Rg5!?

  • Black doesn't need to waste time pawn hunting. He needs to move his passed pawn forward.
  • Better is 43...Ree8 44.Ba4 Re4 45.Bc2 Rf4 46.a3 Be7 when the focus is on Black's advanced passer.

44...Bd6 45.Rd1 Bc7?!

  • This is another critical error that costs Black his passer.
  • Black remains better after 45...Rd8 46.Kf1 Bc7 47.Rxd8+ Bxd8 48.a4 Rg4, since if the e-pawn falls White's pawn at g2 will fall with it and Black will still have a passed pawn.

46.Rd7!

  • Black cannot support his passed pawn.

46...Bb6

  • If 46...Be5 then after 47.Re7 e2 48.Kf2 the pawn falls and the game is equal.

59.Bd5 Rc8+ 60.Kb3 Rd8 61.Bb7 Rd6 62.a4 Bd8

  • 15...Nf6 16.Qc2 Bb4 17.Rf1 Ba3 18.Rd3 Bxb2 19.Qxb2 c5 20.Rfd1 is equal (Miton-Sandipan, Op, Ottawa, 2007).

16.Rf1 Bd6 17.Bd3

  • 17.Rfe1 Bb4 18.Rf1 Bd6 19.Rfe1 Bb4 20.Rf1 Bd6 draw (Carlsen-Leko, IT, Morelia-Linares, 2007).

  • 17...f5 18.Qe3!?

    • 18.Qe2 c5 19.dxc5 Nxc5 20.Bc2 Ne4 21.Bxe4 Bxe4 22.Be5 draw (Wojtkiewicz-Kolev, ZT, Budapest, 1993).

  • The game is equal.

19.Rfe1

    • If 22...Bxe1? 23.Qxh7+ Kf8 24.Bg6! then:
      • 24...Qf6 25.Rxe1 Nc5 26.Bxe8 Kxe8 gives Black an extra pawn for which White has no sign of compensation.
      • 24...Bxf2+ 25.Kxf2 Qf6+ 26.Kg1 Ke7 27.Bxe8 Rxe8 28.Rxd4 gives White an extra piece.

23.Bxd4!?

  • The pawn sacrifice is dubious.

23...Bxh2+! 24.Qxh2 Rxd4 25.Rxd4 Qxd4

  • Black is a pawn to the good with a centralized Queen.

26.Qc7

  • Raiding Black's queenside pawns seems to be what White wanted when he sacrificed on this 23rd move; he cannot possible get adequate compensation beyond a pawn and lost time.

26...Qd2

  • If 26...a6 then:
    • 27.Qa7 a5 28.Qc7 Rd8 29.Kf1 a4 is clearly better for Black.

27.Kf1 Rd8!?

  • Black does not like 27...Ra8 28.Qb7 Qd8 29.Kg1 a5 30.Qf3 Ra7, although he remains a pawn up with good prospects.

28.Qxa7!

  • White has equalized.

28...Rd4 29.g3 h5

  • 29...Rd6 30.Qb8 Qb4 31.g4 g6 32.gxf5 exf5 33.Qc7 remains equal.

30.Qa8!?

  • Unless White can get support for the Queen in its raid (which he can't), he should be content to get his pawn back and retreat.
  • 30.Qxb6 h4 31.gxh4 Rxh4 32.Qc6 Rh2 33.Qf3 remains equal.

30...h4 31.gxh4?

  • At the very least, White should make Black open the kingside on his own time.
  • 31.Qf3 hxg3 32.Qxg3 Qh6 33.Qf3 remains equal.

Scandanavian Game: Horseman Gambit


1.e4 d5 2.exd5 Nf6

  • This is another gambit defense associated with the great American grandmaster, Frank Marshall. Since the sixteenth century, the conventional thing for Black to do is play 2...Qxd5.

          • 7.Bd2 e6 transposes into Watson-Rogers and accompanying lines, above.
      • If 5.Bc4 c6 6.Bd2 Bf5 then:
        • If 7.Nd5 Qd8 8.Nxf6+ gxf6 9.Bf4 then:

  • See also Domínguez - Carlsen. IT, Linares, 2009.

12.Bxe5

  • Black has an extra pawn, but White has the advantage in development.
