Exotic Wijk aan Zee (28.01.2017.)

After Hastings, the next event on the European chess circuit is that held in the Dutch village of Wijk aan Zee, (pop. 2,400) but sponsored by the nearby steelworks, formerly Hoogovens, then Corus and now Tata.

The top Masters Section reads like the membership of some exotic United Nations committee, namely M. Carlsen, (Norway). W. So (Philippines-born). S. Karjakin, I. Nepomniachtchi  & D. Andreikin (all Russia); L. Aronian (Armenia); P. Harikrishna & B. Adhiban (both India): P. Eljanov (Ukraine); R. Wojtaszek (Poland); Y. Wei (China); R. Rapport (Hungary); L. Van Wely & A. Giri (both Netherlands). Even the “local” player, Anish Giri, has a Nepalese father, Russian mother and spent much of his childhood in Japan.

Here is his Rd. 6 win after 5 draws.

White: Anish Giri (2773). Black: Ian Nepomniachtchi (2767)

The solution to last week’s 2-mover was 2.Ra4! and whatever Black tries will be met by different mates.

The final round of the British Chess Problem Solving Championship takes place on Saturday 18th February at Eton College. The competition started last summer with the publication of the “Starter Problem”, in this case a 2-mover by John Rice. Prospective competitors were invited to send in their solutions, and those with the correct key move were sent a set of 8 further problems of varying types and difficulty, to be returned to the organiser by the end of November. Anyone with a good score was invited to the final. The list of qualifiers for this year may be found on the event website.

Here is that starter problem from June 2016, the solution to which was 1.Qb4! threatening 2.Qc4#. Black’s 5 efforts to escape and White’s replies were as follows: 1…Rxb4  2. Nxb4#.

1…Rc5    2.Nb6#.

1…Sc6    2.Nc7#.

1…Bc5    2.Qe4#.

1…Bxe5  2.Rxe5#.

Incorrect solutions submitted, together with Black’s refutations, were as follows:-

1.Qf4?            1…Nf5!

1.Nb6+?         1…Rxb6!
