Chess during Pentecost

During the Pentecost weekend a number of chess tournaments were played and we'll look at a few: the Bussum Open, the Limburg Open, and the GM tournament in Calgary, Canada. GM Dimitri Reinderman was the strongest in the knockout phase that decided matters in Bussum. In Limburg there was a five-way tie for first place among GM Vladimir Dobrov, IM Mher Hovhanisian, IM Daniel  Hausrath, GM Sipke Ernst and IM David Miedema. The tournament in Calgary was won by Wesley So.

Pentecost is the Greek name for the Feast of Weeks, a prominent feast in the calendar of ancient Israel celebrating the giving of the Law on Sinai. Later, in the Christian liturgical year, it became a feast commemorating the descent of the Holy Spirit upon the Apostles and other followers of Jesus Christ. In the Eastern church, Pentecost can also refer to the whole fifty days between Easter and Pentecost. The feast is also called Whit Sunday, or Whitsun, especially in England.

In many countries the following Monday is traditionally a public holiday, and so the long weekend is a perfect opportunity to organize a long weekend chess tournament! In this report we'll discuss two traditional Dutch Pentecost weekenders, the Bussum Open and the Limburg Open, and also a GM tournament played in Calgary, Canada.


Dimitri Reinderman won the 28th BSG Pinkstertoernooi in Bussum, The Netherlands. The grandmaster from Amsterdam finished first on tiebreak after the first six rounds. Then, a knockout phase followed, and Reinderman proved to be the strongest blitz player.

It was the first time that the organizers tried out this interesting format. It was basically an attempt to make the event a bit more exciting, as it avoied the disappointing quick draws that are often seen in the last round of open tournaments. (For instance, in 2004 the author of these lines won the Bussum tournament together with the late IM Leon Pliester after we drew in three moves.)

The top 8 after six rounds qualified for knockout matches while the rest of the participants in the A and B group simply played their final, seventh round. In the playoff Reinderman defeated Peter Ypma, FM Lars Ootes and, in the final, GM Robin Swinkels.

During the same days another traditional long weekender took place in the Netherlands: the Limburg Open in Maastricht. One could say that Bussum's new format was even more justified when you look at the final standings in Maastricht, where five players tied for first place with 5.5/7: GM Vladimir Dobrov, IM Mher Hovhanisian, IM Daniel Hausrath, GM Sipke Ernst and IM David Miedema. Dobrov was declared winner on tie-break. The tournament was stronger than Bussum (GMs Ivan Sokolov, Leif Johannessen and Roeland Pruijssers were among the players who scored 5/7). 

Here's Dobrov's win over French GM Andrei Shchekachev, the game which won the brilliancy prize.

The GM tournament in Calgary wasn't really a Pentecost tournament as it started on May 14th already, but we'll include it in this report as well. It was the 6th edition of the "Calgary International Chess Classic" where, as usual, the aim was to get players scoring IM/GM norms. The format was a 9-round Swiss among twenty players.

This year's edition was the strongest in its history with e.g. GM Wesley So of the Philippines, GM Eugene Perelshteyn of the USA, GM Victor Mikhalevski of Israel, our ChessVibes Training co-editor GM Robin van Kampen and Calgary's own GM Eric Hansen. There was also a Reserve section for amateur players and there were simuls and lectures.

So was in excellent shape and won the tournament with 8/9. He drew two games and won seven. Here's his interesting win against Mikhalevski; the game sees a theoretical exchange of a queen for three minor pieces.

In the same weekend GMs Dimitry Svetushkin and Sergey Ovsejevitsch tied for first place at the 28th Internationale Hasslocher Schachtage while there was a seven-way tie for first between GM Aleksander Delchev, GM Alberto David, FM Julien Song, IM Lucian-Costin Miron, GM Vladimir Epishin, IM Christopher Debray and GM Namig Guliyev at the 37th Open International de Fourmies in France. We like the Bussum idea even more! :-)
