Karácsonyi Simul: A unique world record is broken in Hungary

A rare family chess spectacle took place in Budapest on 28 December, as four members of the Karácsonyi family combined for a 150-board team simul. With all siblings rated above 2000, they moved in sequence across every board, relying on shared understanding of the position throughout the six-hour event. Facing a competitive field, the quartet achieved an impressive overall score, creating what appears to be a unique moment in chess history and an inspiring example of collective play at a high level.
