Quick Summary

Sudden-death time control in chess is a format where each player is allotted a fixed amount of time for all their moves in a game. This contrasts with other time control methods where players might have a set number of moves within a given time, or receive additional time after completing a certain number of moves.

While considered too restrictive in the 19th and 20th centuries because it could lead to a player with an advantage losing due to insufficient time, sudden-death formats have survived in speed chess, such as five-minute games. In more recent times, a hybrid approach has emerged where, after initial time controls, players receive an additional block of time for the remainder of their moves, aiming to reduce game adjournments.123
