Kramnik is still not in form, scoring only 50 %. Van Wely was also in bad form
lately and lost a lot of ratingpoints on the Fidelist. This tournament will have
been a morale boost I think. A surprising winner! These GMs keep getting younger
and younger!
I hope Naiditsch gets invited to some more tournaments.
The combination is not very hard, even I can see how it works! But you have to
find it at the board of course..
As a testposition this is not so difficult for a chessprogram; some

This is Pro Deo 1.1 Vulcan {9k9k}, only change is in evaluation of double pawns.
There are no doubled pawns yet on the board but still the eval is surprisingly
lower than from Vulcan {9k9i}.
