A Weekend in North Holland

The HWP club in the city of Haarlem has celebrated its 75th anniversary in a series of attractive events. The celebrations were concluded last weekend in a strong blitz tournament in which I took part and was lucky to win the senior prize. The final standings may be seen here:

On Sunday I visited the traditional Cultural Village tournament which was played for the first time in a rapid format and took place in café De Zon in Wijk aan Zee. My pupil IM David Klein was the highest rated participant and indeed emerged the unbeaten outright winner.

Results and games may be watched here:

David, a rather busy student in the University of Leiden, has recently been awarded with the GM title provided he will cross the 2500 Elo barrier. He still needs 9 rating points which he hopes to score already in Groningen open later this month. The victory in WAZ seems like a decent warming up.

Martin Minski.

Intermediate Check!

Among my various studies published last year the following was especially tactical:

In pgn.

The German fine composer and devoted promoter Martin Minski was inspired by the punch line and came up with a very interesting logical version. I was flattered by his co-authorship proposal and the joint study was then sent to the 3rd tourney of Maroc Echecs.

In pgn.

A premiere in Morocco for me as well as a pleasant tourney victory. The instructive award of the judge Richard Becker may be seen here:

New Issues

A new issue of the quarterly EG has just appeared. Besides the regular columns and the wealth of recent tourneys’ awards, a great deal of it is dedicated to the great Czech composer Mario Matouš [16.6.1947- 4.7.2013], one of my all time favourites. His countryman Emil Vlasák wrote a lively pictorial obituary illustrated by a small and appetizing selection of the great man’s best efforts of which three were chosen as the Study of the Year in 1990, 1997 and 2007. Here is the first of those three:

M. Matous pgn.

Among the various items in the new issue is my own article: The Magic of the Chameleon-Echo triggered and inspired by the recent Moscow studies composing championship, in which not fewer than three of the awarded studies show doubling of an element on neighbouring lines. Consequently all pieces change their colour (which explains the name of the theme).The second prize-winner in that event displays 2 masked batteries created on neighbouring diagonals:

A. Skrypnik pgn.

If you wish to enjoy the best of the Art of the Endgame Study you are invited to join the happy circle of EG subscribers by simply writing to: Marcel Van Herck: Dit e-mailadres wordt beveiligd tegen spambots. JavaScript dient ingeschakeld te zijn om het te bekijken.

At the same time we have received the November issue of the world’s leading composition periodical The Problemist, published by the British Chess Problem Society and edited by the English player and solver David Friedgood. It’s mainly dedicated to the recent Batumi congress and the 9th World championship for composing. My own regular column Studies presents the usual portion of original entries as well as a short survey of the composing tourneys in Batumi. You may read a lot more about this rich magazine and the BCPS here:    

1. c4!? Having spent part of the last weekend following the world championship match between Anand and Carlsen in Chennai I still managed to take part in a thematic rapid tournament organized by De Pion club in Amsterdam. It was the 19th edition of the Kees Besselink c4 tournament. A normal 7 rounder with 20 minutes per player, however with the unique condition of all games starting with 1.c4. That helps a great deal as you can always blame the opening. Here are the results of the A group:  In this fairly inactive period it’s a good opportunity to stay sharp for the upcoming team matches.

VLG Wageningen at the Lead

The second round of the Dutch team competition was proved successful again for my team of Wageningen. We were paired with the ambitious SISSA Groningen and the match took place in the Mind sports centre in Groningen. Following a close and hard fought match we finally won 5.5: 4.5. Here are the individual results:

This weekend I visited the last 2 rounds of Hoogeveen tournament to see the young Philippine Wesley So winning the crown group and the Israeli GM Maxim Rodshtein winning the main open following a last round thriller. All results, games and photos may be seen here:  

An older endgame study of mine was the event’s challenger:

Here it is in PGN and auto-play formats.
