[what is this?]

GMC Joop van Oosterom was born in Hilversum on December 12th, 1937, five days after Max Euwe lost the world title. His first notable success at chess occurred in April of 1955, when he became the Dutch Youth Champion in Enschede. However, financial and professional interests would soon separate him from competitive chess for many years.

In 1966, two ex-IBM employees, Van Oosterom and J. C. Mol, founded the Automation Center Volmac, the first Dutch software company. In 1988 Volmac went public and Van Oosterom and Mol became multi-millionaires, obtaining cash and stock for their stake in the company. According to Dutch financial magazine "Quote 500," Van Oosterom's wealth is currently estimated in excess of 1 billion Euros.

By the early 1980s, Van Oosterom was secure enough to devote attention to his first love. He was Dutch CC champion in 1980-1981, and played in a number of other correspondence events, including winning the Three-Quarter-Final Candidates section of the 14th World Championship which began November 1987, and was awarded the CC-IM title as a result. In February of 2005, Van Oosterom achieved his lifelong goal as he became the 18th World Chess Correspondence Champion. He crowned this success by becoming the 21st World Chess Correspondence Champion in 2007 also.

A true philanthropist, Van Oosterom became involved in chess sponsorship, through the Max Euwe Association that he founded. Starting in 1992, he began to sponsor the innovative Melody Amber tournaments, involving leading GMs in both rapid and "blindfold" games. This tournament was conducted annually for 20 years. Brother of Henny van Oosterom.

Mar-21-05  DP12: Actually if you analyse this line with g4 against the Najdorf I think the critical game is Gormally v. Kaufman which showed close to a forced perpetual in the g4 lines. But to say that the English attack is not dangerous is not right at all... especially in the e6 lines white has a strong position although of course black has counterchances which if he exploits well, he can turn the game. e5 has Kasparov as has been used alot lately seems more solid but of course white still has to be at least slightly better although of course your point that whoever is most comfortable (i.e Kasparov) will win.
Apr-15-06  EmperorAtahualpa: An article in Dutch by GM Hans Ree about correspondence chess and world correspondence chess champion Joop van Oosterom:


Door Hans Ree

In het correspondentieschaak mag alles. Je mag computers gebruiken en vrienden om raad vragen, zelfs als die vrienden veel sterker schaken dan jij zelf. Om het te verhinderen zou je een sterke geheime correspondentieschaakpolitie nodig hebben, dus een verbod is zinloos.

Vorig jaar werd de Nederlandse financiėle zwaargewicht Joop van Oosterom de 18de wereldkampioen correspondentieschaak. Er wordt vaak gezegd dat hij bij het spelen van zijn partijen geholpen wordt door de topschakers die in zijn jaarlijkse Ambertoernooi mogen spelen, maar ik denk dat dat niet juist is uitgedrukt. De partijen die hij in dat wereldkampioenschap speelde en de analyses die hij er later over publiceerde zijn zo fantastisch goed dat ik er van overtuigd ben dat hij zich er zelf helemaal niet mee bemoeid heeft.

Zoals gezegd, het is niet tegen de regels, maar het zou zuiverder zijn als dat wereldkampioenschap zou zijn toegekend aan Van Oosterom Holding of iets dergelijks. Bij autoraces en in de paardensport is het ook niet zo dat de eigenaar van de renstal zelf tot wereldkampioen wordt benoemd.

Het lijkt me dat er voor de beste correspondentieschakers weinig aardigheid meer aan is om aan een wereldkampioenschap mee te doen waarvoor het anonieme collectief van Van Oosterom zich ook heeft ingeschreven. Misschien komt het daardoor dat twee oud-wereldkampioenen samen de strijd zijn aangegaan, man tegen man, net als vroeger.

Het zijn Mikhail Umansky, een Rus die in Duitsland woont, en de Nederlander Gert Jan Timmerman. Umansky was de 13de wereldkampioen in het correspondentieschaak, van 1998 tot 2000, en Timmerman de 15de, van 2001 tot 2003.

Sinds juli 2005 spelen ze een match van zes partijen. In vier daarvan waren gambieten voorgeschreven. De partijen kunnen worden gevolgd op de website en ze zijn volgens mij van een grote diepzinnigheid die in het gewone schaak meestal niet haalbaar is. Als ik het goed begrepen heb is de bedenktijd in iedere partij 60 dagen voor 10 zetten.

  whiteshark: Dear Mr. van Oosterom,




May-13-07  Caissanist: If Piket really did play Oosterman's games then his opening repertoire has undergone a huge change in a relatively short time. Piket never played the Najdorf Sicilian as black, and only rarely opened 1.e4 as white.
May-17-07  Manic: This is the guy who is our opponent in the next Chessgames challenge right?
May-17-07  Karpova: No, Gert Jan Timmerman will be our opponent.
May-31-07  Karpova: Now it's official: Joop van Oosterom is the new World Champion of Correspondence Chess!

The only one who could have caught him was our GM Nickel (with 6 points and four games not finished yet) but he said himself that he would likely score 2/4 from the last games.

He drew Hector Walsh (2649) but would have had to win all of the remaining games. Crosstable:

Congratulations to Mr. Oosterom!

Jul-02-07  Prokofiev fan: He probably used his billions to buy a supercomputer or two, and low and behold he is the WCCC.
Jul-02-07  russep: Exactly how is correspondance chess played what are the rules.

  Willem Wallekers: <offramp: ... but has their relationship continued now that Piket is inactive.> Yes, it has. Piket got a job in a company of Van Oosterom
Mar-12-11  gauer: Hats off to Mr. Oosterom for 20 years of sponsoring & organizing a gold standard of Melody blindfold / rapid events.

Oct-31-14  john barleycorn: <eternaloptimist: He is currently the #1 ranked correspondence chess player in the world!>

This qualifies him for challenging <TheWorld>.

Premium Chessgames Member
  eternaloptimist: <john barleycorn> Indeed it does qualify him for that! Naiditsch is clearly no match for the CG team. We need to face a correspondence GM, not a regular GM. I might submit a request to to have our team face a corr. GM for our next game.

  diagonal: <Although it was commented in the chess circles already for some time, the news that probably the biggest chess mecenas of the 20th century Joop van Oosterom had passed away at the end of 2016 became official only now.

It is difficult to express how much this man meant for the chess world only with a few words. He sponsored a countless number of chess events: The Melody Amber Rapid and Blindfold Chess Tournament as the most famous one.

Van Oosterom also helped the local chess club in Monte Carlo, the small nations, the Volmac chess club, ladies, veterans and young players, always providing fantastic playing conditions for everyone. Practically all the big names in the chess world took part at least once in those events in Monaco, Nice, Amsterdam, Aruba or other cities.

Joop van Osteroom was a stong player himself and even took part in a World Youth Chess Championship in 1955. He also became two times a World Correspondence Champion in 2005 and 2008.


Veselin Topalov expresses his sincere condolences to the widow of Joop van Oosterom, Muriel, as well as to his daughters Melody and Crystal.>

He bought his titles. So that is a joke. That Susan rat praises him says enough I think. Rats will be rats and die like rats. That's right 😊
