Bu Xiangzhi wins Blindfold Chess World Cup in Bilbao

10/21/2007 – He led the event from start to finish, and until the last round had not lost a single game (performing, incidentally, at almost 3000 Elo). But even the last-round loss to Judit Polgar could not stop the remarkable Chinese GM from taking first. Meanwhile Sergey Karjakin overtook his great rival Magnus Carlsen to win Silver. Final report.
 

Bilbao Blindfold Chess World Cup

The Bilbao Blindfold Chess World Cup took place from October 16th to 20th, 2007, in the Hotel Sheraton Bilbao. The participating players are listed in the graphic below (provided by the official web site):

The Blind Chess World Cup was played in semi-rapid match mode, as a double round robin, with each pairing playing a mini-match of two games each day of the tournament. Time controls were 25 minutes per player for the entire game plus 10 seconds increment per move.

Round nine was remarkable, with all games won by White. The Chinese former child prodigy Bu Xiangzhi put an end to all our theoretical scenarios by winning his first Saturday night game against Judit Polgar, thus reaching a point score that nobody could come near. At that stage the astounding Bu had scored 7.5 points from nine games, with a rating performance of 2990 (i.e. he achieved a result against a field of 2710 average GMs that you would expect from a player rated 2990). Meanwhile Magnus Carlsen, the youngest player in the tournament, defeated former FIDE world champion Veselin Topalov quite convincingly, and seemed well on the way to occupying second place. Pentala Harikrishna continued his grim fight for last place with a loss to Ukrainian GM Sergey Karjakin.

In the final round Judit Polgar, the strongest female player in history, by a long margin, fought hard to take back a point from Bu. The Chinese player suffered his first and only loss in this event. Sergey Karjakin won his second game against the luckless Harikrishna, and since Magnus Carlsen drew against Topalov he was overtaken by Karjakin according to the Bilbao scoring rules (see below).

Final results

Using the traditional point system, the final cross table would look like this:

In Bilbao wins counted for three points and draws for one. So the scores according to this system are calculated as follows:

Player

2. Sergey Karjakin

There is one clear difference between both tables. Before the final two rounds Magnus Carlsen had been in second place, half a point ahead of Sergey Karjakin on the traditional table and one point ahead in the Bilbao system. In the last two rounds Carlsen won one game and drew the second, while Karjakin won both games. On the traditional table Krajakin caught up with Carlsen, though he had a slightly worse tiebreak score. On the Bilbao table he overtook Carlsen – that is the point of wins counting more than double that of draws – and landed clear second.

So what effect did the Bilbao system have on the draw statistics. After all this is the reason for introducing the three-points-for-a-win system. Here are the statistics:

As you can cee the drawing percentage is extremely low, just 30%, which would seem to convincingly justify the scoring system. On the other hand in blindfold chess errors occur very frequently and lead to fewer draws than would occur if the players could see the board. So the jury must remain out on the advantages of the scoring system. It would be interesting to stage a few high-profile tournaments with high prize funds – no appearence fees – to see if players will change their styles, avoid draws and go for the money.
