Wesley So, Levon Aronian, Leinier Dominguez and Sam Shankland all have something in common. They play for the US national team, and they are all Libra. Although many Libra grandmasters play excellent chess, none have won a world championship title, except for Ruslan Ponomariov, who won the FIDE title in 2002. Even legends like Ossip Bernstein, Viacheslav Ragozin and New York-born Reuben Fine were close, but not close enough. Maybe it's because Libras bring too much lightness to the game? | Photo: Pixabay
