Who is Wesley So?

Wesley So was born in Bacoor, Cavite, in the Philippines, in 1993, and was a chess prodigy from a young age. He earned the grandmaster title in 2008 at just 14 — the youngest Filipino GM in history and, at the time, one of the seven youngest grandmasters the game had ever seen. He also became the youngest player ever to cross the 2600 rating (in October 2008), a record that had previously belonged to a teenager named Magnus Carlsen.

In 2012 he moved to the United States to study at Webster University, joining the powerhouse college chess program run by grandmaster Susan Polgar. He transferred to the US Chess Federation in 2014, turned full-time professional, and quickly rose into the world’s top handful of players. In February 2021 he became a US citizen. Today he’s one of the faces of the American chess boom, alongside Fabiano Caruana and Hikaru Nakamura.

What is Wesley So’s playing style?

If Carlsen is the great “grinder” and Caruana the great “preparer,” So is the great technician. His chess is calm, clean, and precise — he built a reputation for a low-risk, positional style that rarely overreaches, quietly improves his pieces, and pounces the moment an opponent slips. He’s famously hard to beat: he goes on long unbeaten streaks precisely because he almost never hands you a free point.

What openings does Wesley So play?

So’s repertoire matches his temperament: sound, classical, and reliable. As Black against 1.e4 he leans heavily on the Ruy Lopez — especially the rock-solid Berlin Defense — and he’s equally at home in quiet, maneuvering Italian Game (Giuoco Piano) positions as White. Against 1.d4 he trusts classical, well-tested setups like the Nimzo-Indian and Queen’s Gambit structures.

The Berlin Defense of the Ruy Lopez — the calm, rock-solid line that sits at the heart of Wesley So's repertoire as Black.
