Wesley So was born October 9, 1993, in Bacoor, Cavite, Philippines. He became one of the strongest Filipino grandmasters, then switched to representing the United States in 2014. He won the US Chess Championship in 2017 and 2021, was ranked in the world’s top 5 at his peak in 2017, and won the inaugural FIDE Fischer Random (Chess960) World Championship in 2019, defeating Magnus Carlsen in the final.

His style is solid, precise, and technically excellent. He doesn’t play for complexity or chaos, he plays for small advantages, converts them with endgame technique, and avoids the mistakes that cost other players points. The chess is less spectacular than Tal or Carlsen at their best, but the results have been consistently elite for over a decade.

Philippines to the United States

So was one of the strongest players to emerge from the Philippines, a country with a respectable chess tradition but no previous top-10 grandmasters. He represented the Philippines until 2014, when he switched to the US federation. The switch generated some controversy in the chess world, federation changes of this magnitude are uncommon and the Philippines had invested in his development.

He has been unambiguously American in his chess career since 2014, winning the US Championship twice and playing on the US Olympic team.

The Fischer Random Championship

The 2019 Fischer Random World Championship (played in Chess960, where the pieces are randomly placed at the start of the game, eliminating opening preparation) was the first of its kind. So won it, beating Carlsen 13.5–12.5 in the final. The result showed that his understanding of chess structures extended beyond memorized openings.

Bobby Fischer himself proposed Chess960 as a solution to what he considered the excessive role of opening memorization in modern chess. The format requires players to understand the game from the first move rather than relying on preparation, which suits players with deep structural understanding over those with encyclopedic opening databases.
