Peter Lékó and Levon Aronian could argue during the WEISSENHAUS Freestyle Chess G.O.A.T. Challenge about which of them was the first world champion in chess960. Both would be right. Lékó won a 960 match against Michael Adams in 2001, the first such match between super grandmasters, which was only subsequently declared a world championship. When Aronian won in 2006, the private tournament was already called the World Championship.
Lékó certainly has one thing over Aronian in the 960 context: he played the game with the man who invented it. Chess960 is also known as “Fischer Random” because it is based on an idea by Bobby Fischer. Fischer lived in Hungary for a while in the 1990s, where the exceptional talent Lékó caught the attention of the former world champion. And so it came about that the two played a few games in private.
