- Peak rating of 2768 (2014). A figure that puts him firmly in super-grandmaster, world-title-contender territory.

Trivia & fun facts
- A “solid” player who’s also a blitz king. It’s a rare combination: Domínguez is famous for slow, careful, deeply prepared classical chess — and yet he’s an outright World Blitz Champion. Clean chess doesn’t fall apart when the clock speeds up; it thrives.
- He was Caruana’s second in a World Championship match. When Fabiano Caruana challenged Magnus Carlsen for the crown in 2018, Domínguez was on his team helping prepare openings — a job reserved for the very best theoreticians in the world.
- Part of the Capablanca lineage. As Cuba’s long-time No. 1, Domínguez carried forward a chess tradition that runs back to José Raúl Capablanca, one of the greatest players in history and a Cuban national hero.
- A double-life repertoire. He plays the ultra-solid Petroff Defense to hold the draw and the razor-sharp Najdorf Sicilian to play for the win — proof of just how complete his preparation is.
- An overnight American star. The moment he switched federations in December 2018, he became one of the top-five players in the United States without playing a single new game — that’s how strong he already was.
- Part of an American super-team. His switch added elite depth to a US squad already loaded with Fabiano Caruana, Wesley So, and Hikaru Nakamura — arguably the strongest national chess lineup of the modern era, and one he debuted for at the 2022 Chennai Olympiad.
