These are not random games. They are chosen to show different sides of Niemann’s chess: the famous wins over Magnus Carlsen, a direct attacking finish, a practical squeeze against Christopher Yoo, and an early long-form grind that ends in mate.
| Date | What happened | Why people still ask about it |
|---|---|---|
| August 2022 | Niemann beat Carlsen in the FTX Crypto Cup with the black pieces. | It became an earlier reference point once the bigger September dispute erupted. |
| September 4, 2022 | Niemann defeated Carlsen in round 3 of the Sinquefield Cup in Saint Louis. | This was the result that triggered the entire public storm. |
| September 5, 2022 | Carlsen withdrew from the tournament. | The withdrawal was unprecedented and widely interpreted as a major accusation. |
| September 2022 | Niemann admitted cheating in online games when younger, but denied cheating over the board. | A lot of online confusion mixes online admissions with over-the-board claims. |
| September 19, 2022 | Carlsen resigned after one move in an online rematch against Niemann. | That moment turned chess drama into mainstream sports news. |
| October 2022 | Chess.com published its report, and Niemann filed a lawsuit over the allegations and fallout. | This shifted the story from gossip to documents, statements, and legal filings. |
| August 2023 | Chess.com and Niemann announced an agreement; Niemann was reinstated and Carlsen said he would play him if paired. | It ended the formal standoff without ending public debate. |
