Corus Studies Day: solution and two new problems
The 22 solvers at the study competition had three hours for the nine tough
positions, most especially created for this event. At the awards ceremony the
chief organiser Yochanan Afek presented some of the studies to the audience
and journalists, and in a highly entertaining (and inspiring) session demonstrated
the solutions.

Here was one of the studies which we gave you to solve by yourselves.

White to play and draw
1.g5! The only way to meet the promoting threat as 1.Rxd2 1.Rxd2? loses
to 1...Qe8 or 1...f6.
1...d1Q+! 2.Rxd1 g6+! Since 2...Rxd1 3.Qa4+ Ke7 4.Qxd1 g6+ 5.Kh4
is just draw. 3.Kh6 Rxd1 4.Qa4+ Ke7 5.Qxd1 Kf8! Preparing a mate net
by Kg8 and Qf8. 6.Qd4! The threat is of course 7.Qh8+. 6...Qb2!
7.Qh8+!! The stunning point of the whole study: a neat sacrifice of
the queen! 7...Qxh8 8.f6! Ke8 9.g4 Qf8+ 10.Kxh7.
A tremendous finale: Black, a queen up and a move at hand cannot avoid stalemate!
(Of course he can sacrifice the queen iwht an immediate draw). Another outstanding
and breathtaking masterpiece from the workshop of the prominent Israeli composer
who lives in San-Francisco. Draw. [Click

Two new studies from the Corus Study Day
In our report we were only able to publish the above study, since the other
equally spectacular examples were being submitted for prize competitions. In
the meantime two more have been published in The Problemist and we
have permission to reproduce them.

IM Yochanan Afek sent us two new studies for you to solve
Piotr Murdzia + Andzey Jasik
The Problemist 2009

White to play and draw
It looks as though White has an easy draw, but after the obvious key you must
look for a spectacular black counter-attack. White has to set up a very clever
positional draw in order to save the day. Peter Murdzia (Poland), a strong over-the-board
IM, is the current world champion solver. He could not attend the event this
time and sent this lovely study with greetings instead.

White to play and win
This study by the legendary over-the-board Dutch grandmaster contains an very
beautiful pawn sacrifice, the purpose of which only becomes apparent at the
end of the winning line.
Editorial note: The solution to these new studies will
be given in a few days. We urge our readers to try and solve both themselves.
The solutions contains some astonishing moves and beautiful ideas and
demonstrate how far the art of study composition has progressed.
