GMHans Moke Niemann

Hans Niemann was born in San Francisco and began chess while living in the Netherlands as a child. After returning to the United States, he studied in California, Connecticut and New York. He supported his early professional ambitions by teaching chess. At eleven he became the youngest winner of the Mechanics' Institute's Tuesday Night Marathon. He won the K-8 section at SuperNationals in 2017 and became an international master in 2018. He earned the grandmaster title in 2021 and won the World Open that July. His victory over Magnus Carlsen at the 2022 Sinquefield Cup brought both attention to his playing strength and a major dispute over cheating allegations. The resulting legal case was settled in 2023. His competitive career continued, and he reached twelfth in the world in May 2026.
