Whats a chess clock and how do they work?
A. A chess clock is actually two clocks! When you’re thinking, your clock ticks down. After making a move, you hit a button at the top of the clock and your opponent’s clock starts ticking. If you run out of time, you lose the game, unless there is checkmate on the board or your opponent has insufficient mating material. There are two main types, the digital and analog clock. As stated in the tournament rules for the Standard Tournament “2. Clocks: 2a. Clocks will only be used when both players agree. However, players on the top 10 boards of each section during rounds 3-6 will be required to use a clock if one of the two players requests it and provides a clock. 2b. Time control for this tournament is G/30 (30 minutes per player per game). Chess Clocks will be set for 30 minutes for each player. NO time delay will be used.” Additionally, clocks may be used when a resonable amount of time has elapsed without significant progression in the game.
