412:, its inventor), like increment, adds a fixed amount of time after each move, but no more than the amount of time spent to make the move. For example, if the delay is ten seconds and a player uses ten or more seconds for a move, ten seconds are added after they complete their move. If the player uses five seconds, only those five seconds are returned to the clock. This ensures that the main time left on the clock can never increase even if a player makes fast moves. As with increment, under FIDE and US Chess rules, the delay time is applied to the first move.
270:
time (verbally) begins once the player falls below a certain threshold of time, such as 10 minutes; when the time is being counted, the player is informed at intervals how much time they have used in their current period, and how many extra periods they have left. (For example, the time may be called at 10-second intervals, and when 55 and 58 seconds have been used; during a player's final minute, the last 10 seconds are counted one by one.) Similarly, in the televised

317:, players stop the clock, and the player in overtime counts out the required number of stones and sets the remaining stones out of reach so as not to become confused, whilst the opponent sets the clock to the overtime period. If all the moves are made in time, then another period of overtime starts — another set of stones and the timer again reset to the overtime period. If all the moves are not made in time, the player has
369:'s patent on it), 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.
184:, the time control is standardized to 25 minutes per side with a 10-point penalty for each minute or part thereof that is used in excess, so that overstepping the allotted time by 61 seconds carries a 20-point penalty; a player who oversteps by 10 minutes automatically loses; in this case, their opponent is given enough additional points to win by one point, if they were not already in the lead at that time.
305:, with designations such as "5 minutes + 12 seconds per move". Under this time control each player has twelve seconds added to their clock after every move, starting from the first move, regardless of how much time they spend on each move. Thus if a player thinks for eight seconds before making their first move, they will have five minutes and four seconds on their clock after making it.

uses a similar system, but the byo-yomi time is variable and always covers 25 moves. Thus the time control "20 minutes + 15 minutes byoyomi" on IGS means that after the initial 20 minutes of thinking time are over, a player is granted 15 additional minutes, which may be spent however they choose.

games and many amateur tournaments, a player has several byo-yomi periods, for example five periods of one minute each. If a player makes their move within a one-minute period, they retain all five periods for their future moves. If a player oversteps one minute, they start the following move in the

A typical time control is "60 minutes + 30 seconds byo-yomi", which means that each player may make as many or as few moves as they choose during their first 60 minutes of thinking time, but after the hour is exhausted, they must make each move in thirty seconds or less. To enforce byo-yomi, a third

In higher-level tournaments, such as the Kisei tournament, the player's time is often composed entirely of byo-yomi periods (for example, in an eight-hour game, the player may have 480 periods of one minute each), rather than having a main block of thinking time.

After the main time is depleted, a player has a certain number of periods (for example five periods, each of thirty seconds). If a move is completed before the time expires, the time period resets and restarts the next turn. If a move is not completed within a time period, the time period will
