Corus Studies Day: Twan Burg – a stunning victory
By IM Yochanan Afek
The talk of the day in Wijk aan Zee, was the amazing performance of young Twan
Burg in the first Corus solving tourney for endgame studies. The 18-year-old
HMC Den Bosch player from Schijndel (a small town in the province of Brabant
in the Netherlands) emerged a clear victor, ahead of a highly experienced field,
including two times solving world champion GM John Nunn and members of the Dutch
and Belgian national solving teams.

The study solving champion in Wijk: Twan Burg from Schijndel
22 solvers worked hard for three hours, to crack nine tough studies, especially
created for this event by such composers as Jan Timman, Yochanan Afek, Piotr
Murdzia, Andjey Jasik, Gady Costeff, Ilham Aliev and Siegfried Hornecker. None
of the solvers managed to solve them all, but Twan came first by conquering
seven of them. He scored 36 points out of the maximum of 45.

The favourite, British GM John Nunn, ended up second, scoring 32 points, ahead
of the Belgian champion Eddy van Beers, who had 28 points. Following the money
prize winners came Dutch solving champion GM Dolf Wissmann and Martin van Essen,
with 22 points each.

Participants and press at the prize giving
The event was sponsored by Corus tournament, ARVES (the Dutch-Flemisch association
for Endgame studies) and Harold van der Heijden. Chief arbiter was Ward Stoffelen
from Belgium. Corus officials Theo Hoogland and Arno Vrins expressed their wish
to host the event also next year as part of the world's most prestigious chess
festival.

Famed expert and collector Harold van der Heijden presents solving GM Dolf
Wissman his famous database of 70,000 studies as a prize.
A special booklet (edited by Luc Palmans and printed by Bernd Ellinghoven)
was presented with the full award of last year's monumental Corus-70 composing
JT for endgame studies and distributed among the players.

This year we have also witnessed an immense growth in the popularity of the
daily Corus two-mover challengers. An average of 500 daily entries on the official
website and dozens of daily visitors as well as players and officials in the
tournament venue, regularly handed in their solutions. The chief arbiter asked
every day for copies for all his colleagues, using it as an enjoyable pastime
during the lengthy playing sessions. Even GM Vassily Ivanchuk was seen solving
a challenger while playing against GM Karjakin, and smiling when he finally
found the key, which eventually seemed to inspire his splendid victorious performance
in this game…

White to play and draw
Editorial note: The solution to this incredible study
will be given here in a few days. We urge our readers to try and solve it themselves.
The solution contains one of the most astonishing moves and beautiful traps
we have encountered in a long while. Note that we are unable to publish the
other equally spectacular studies yet, since they are being submitted for prizes.
We hope that with Yochanan Afek's help we will be able to show them to you when
they are free for reproduction.
