2.13 Seconds Chess, or, Realization That Magnus Is Losing, is a series of video edits based on a clip of chess player Hikaru Nakamura getting up from a game, looking at a game being played by Magnus Carlsen and Vincent Keymer, and expressing shock about how the game is going after purportedly noticing that Magnus is losing.
The clip comes from a game at the FIDE World Cup 2023, which Carlsen ended up losing. The video became the subject of memes in October 2026, which focus on how fast it took Nakamura to realize that Carlsen, considered one of the best professional chess players, is losing.
