I reported last week on the final results in the superb top group at Wijk aan Zee won by Peter Leko and the very strong "GM B" in which the young Ukrainian star Sergey Karjakinran out the winner. But such is the strength in depth in Wijk that even the third group "GM C" is more than worthy of attention.

This year's event averaged a very respectable 2442 (category 7) - a more or less average international tournament: with the field of 14 including two players just over 2600, Russians Evgeny Aleseev and Alexey Korotylev and a couple over 2500 - Vladimir Georgiev (Macedonia) and IM Erwin L'Ami (Holland); though the tail was of course much longer than in "GM B".

In a closely contested event, it was Georgiev who ran out the winner on 10.5/13 ahead of Korotylev and Women's Grandmaster Natalia Zhukova (Ukraine) 10; and L'Ami and Alekseev 9.

This group of five was well clear of the rest none of whom got more than 50 per cent. The result which really stands out is Zhukova's big score. She won eight lost just one (to Korotylev) and drew four. Her last round win against Manuel Bosboom involved a large accident in which he missed that his f pawn was pinned.

In a very messy French, Bosboom's troubles started in the diagram in which he can probably safely take the exchange with 25.Qa3+ though his reluctance to weaken the white squares was understandable. Instead, he erected a powerful barrier along the long white diagonal but simply missed that his forcing moves were "preparing" 28...Rxg3+.
