A time control method with time delay, invented by Bobby Fischer. When it becomes a player's turn to move, the delay is added to the player's remaining time.

Fischer Delay is an increment timing method often used in chess.

In this method (also known as increment, bonus, and Fischer, after Bobby Fischer's patent on it) timing method, a specified amount of time is added to the player's main time after each move, unless the player's main time ran out before they completed their move. For example, if the time control is "G/90;inc30" (90 minutes of main time per player, with a 30-second increment each move), each player gets an additional 30 seconds added to their main time after each move, unless the player's main time ran out first.

Under FIDE and US Chess rules, each player gets the increment for the first move as well. For example, with "G/3;inc2", each player starts with three minutes and two seconds on the first move. Not all digital chess clocks automatically give the increment for the first move; for those that don't, the increment time has to be added manually.
