Batumi Chess Olympiad 2018

[Hans Jung]

China beat the surprise Polish team decisively in rd 10.

[Hans Jung]

Poland almost did it! Two rounds away from the gold and still a chance. They had upset some great teams and were leading going into rd 10.

[Hans Jung]

US vs China for the gold tomorrow.

Batumi Chess Olympiad 2018

October 4, 2018

Round Ten

From Peter Doggers at chess.com

Board one Ding Liren was Jan-Krzysztof Duda's third 2800 opponent in the tournament, but the first he failed to hold the draw against.

Early in the game there was a move repetition, but Ding decided to continue. Soon after, he found an amazing piece sacrifice and ended up winning a dazzling game.

Keep in mind that he needs to sit on a special, softer chair, and still walks on crutches. Although he is used to them by now (he needs them for another two months or so), Ding told Chess.com that he drinks less water to avoid having to go to the toilet!

China - Poland 3-1

OPEN SECTION CALCULATIONS FOR GOLD

U.S. (17 points): Wins gold by beating China. Can also win gold by tying China and hoping to maintain its very small edge on tiebreaks. Cannot win gold with a loss.

China (17 points): Wins gold by beating the U.S.. Can also win gold by tying the U.S. and having France-Russia draw and Poland not win; or by tying and having its previous opponents do well enough to overcome the small tiebreak deficit with the U.S. and Poland.

France, Russia, Poland (all 16 points): Must each win and have U.S.-China be a draw. Must also hope for previous opponents to do well to overcome tiebreak deficit (note that Poland already has better tiebreaks than anyone, even the leaders).

_________

WOMEN'S SECTION CALCULATIONS FOR GOLD

China (17 points): Wins gold by beating Russia. Can also win gold by drawing Russia and maintaining its superior tiebreaks over all the teams that could then tie it (Ukraine, U.S., Armenia). Could even lose the match and win a multi-team tiebreak event, but only if U.S.-Ukraine is a draw and if Armenia does not win.


Ukraine (16 points): Wins gold by beating the U.S. and China loses and Armenia does not win. Could also win and have China tie, if many of its previous opponents score well enough to overcome a tiebreak deficit with China.

U.S. (16 points): Wins gold by beating Ukraine and China loses and Armenia does not win. Could also win and have China tie, if many of its previous opponents score well enough to overcome a tiebreak deficit with China.

Armenia (16 points): Wins gold by beating Georgia one and China loses and U.S.-Ukraine is a tie. Could also win and have China tie, if many of its previous opponents score well enough to overcome a tiebreak deficit with China.

[Hans Jung]

Congratulations to Team Canada for making a comeback after several tough losses and finishing 23rd.

[Hans Jung]

The ladies had a reasonable result coming close to their starting rank.

[Hans Jung]

Americans are probably disappointed with the 4 draw split with China as China got the gold and US the silver. Russia made a comeback to get the bronze.

[Hans Jung]

Fabiano Caruana and Sam Shankland showed great form. Fab Fabi is only a few rating points back of Magnificent Magnus and Sam Shankland has shown that he belongs in the top 25 of the world.

Fabiano Caruana:

Last Olympiad we benefited from the tiebreak system; this time unfortunately, we didn't. Nevertheless, silver is a good result and I'd like to thank all my team members for their dedicated work. Congrats to China on gold in the Open and Women's sections!

[Frank Dixon]

Both Men's and Women's Canadian teams should be very proud of their performances at the Olympiad!!

[Victor Plotkin]

Very proud of what exactly? Of lucky pairings in the last 3 rounds?

More on Russia – China (Women) in Round Eleven

From Sagar Shah at chessbase

https://en.chessbase.com/post/china-...th-double-gold

“Aleksandra Goryachkina quickly built up a winning position against Shen Yang. She played some amazing sacrificial chess and crowned her strategy with a mating attack.

This game also received the best game prize in the women's section of the entire event!”

“Lei Tingjie's draw motivated Ju Wenjun to try her best. The score was 2-1 now and if she won the game a 2-2 tie would mean Ukraine and China would be at the top with 18/22. The game was equal throughout. It seemed impossible that Kosteniuk would lose that game. But Ju Wenjun didn't give up. She kept moving around and at some point she won a pawn. The position was still even, but in that stressful environment where you have spectators, coaches, arbiters, media around you, the chances of making a mistake are very high. Somewhere around move 83 when the position was still equal Kosteniuk claimed a three-fold repetition. The arbiters decided to make the moves on the board to check the authenticity of the claim. It took nearly half an hour to do that . At some point, Kosteniuk understood that her claim was wrong and was not happy with what was going around. This half an hour break surely took a toll on her.

The game resumed but Alexandra was not herself. She blundered immediately and lost the game. It was a humongous effort by Ju Wenjun who showed why she is the current World Champion. She could have taken a draw and no one would have told her anything as the position was drawish for so many moves. But she fought on. She persevered. For her team, for her country and they were rewarded with the gold medal. China tied for first place with Ukraine, but the tiebreak favoured the Chinese women. Spare a thought for the Russian women who fought so hard but had to be content with the fourth place.”

Position after Ju Wenjun’s 83…Kf6




Some Comments from the EC Forum:

Chris Rice:

Pure drama at the end in the Ju Wenjun - Kosteniuk game and Ju Wenjun gives her side of the story in a 4 minute interview to chess.com. She wasn't sure that the Kosteniuk claim was going to be turned down and even when it was she couldn't see how to win until Kosteniuk made the fatal error of moving the knight to f4.

Christopher Kreuzer wrote:

Having played through the game where Kosteniuk made an incorrect threefold repetition, I have some sympathy. She made the claim at move 83, and between moves 76 and 84 it does feel like the position might have repeated several times, but it hadn't been three times.

Note that the positions after White's 76th move and Black's 84th move are the same, but with a different player to move. Black effectively triangulated with her king on these squares: g6-f7-f6-f7-e8-d7-d6-e7-f6-g6. White had run out of checks by that point.

Roger de Coverly:

I'm marginally surprised it isn't a feature of the DGT boards (or rather the software that transmits the moves to the world) that they flag up repetitions, thus enabling arbiters to give an instant decision. But the arbiters at match level may not have access to this. "Computer says no" might not have been accepted by the player making the claim.

Mike Klein at chess.com

A few dozen spectators and several big TV cameras were fighting for spots around the board, while being chased away by the furious Russian team captain GM Sergey Rublevsky and the arbiters.

The spectacle took a new turn when Kosteniuk suddenly claimed a three-fold repetition. In a small twist of geopolitical irony, Ukraine's victory depended on a Russian claim.

The match arbiter stopped the clock and started to reconstruct the game (thereby making the mistake of allowing the players to think on about their game while the clock wasn't running).

At some point, chief arbiter Takis Nikolopoulos returned into the playing hall and ordered the arbiter to go through the game with the players. The claim turned out to be incorrect.

With extra time on the clock for Ju, the game continued. Kosteniuk seemed to have distracted herself mostly. She failed to concentrate fully and soon made the ill-fated decision to play actively.

She maneuvered her knight to a worse square, which allowed Ju to win material.
