The 75th running of the annual Tata Steel Chess Tournament begins today. As the folks at Chess Vibes note, this is one of the two or three most important tournaments of the regular chess calendar:
Six players out of the current top ten will be present in Wijk aan Zee. Besides Anand and Carlsen there's three times winner Levon Aronian, fast-rising star Fabiano Caruana and former winners Sergey Karjakin and Hikaru Nakamura.
The event has only recently been known as the Tata Steel tournament.
The event has been held since 1938 and until 1999, the year of the famous game Kasparov-Topalov, the event was called Hoogovens Tournament. Between 2000 and 2010 the name was Corus Tournament and since 2011 it is called Tata Steel tournament, after Tata Steel bought Corus in April 2007 for 8.1 billion Euros.
When I was younger many people just called it "the Wijk aan Zee tournament"; Wijk aan Zee is a small resort town on the Dutch coast where the tournament is always held. Follow all the action at the official site.
