Circular chess - meaning and definition. What is Circular chess

Introduction To Chess ClocksA chess clock is a handy tool usually used to time the game per player in a chess tournament.We use clocks in chess to regulate and track the time and add more exhilaration to the game. In this article, we’re going to learn about chess clocks. Brief History Of Chess ClocksLet’s start this mini chess history class with this fact:A famous match between Howard Staunton and Pierre St. Amant in 1843 reportedly lasted 14 hours!Chess has always been a time-consuming activity, but they were especially so in the past.In the early 1800s, chess games could last anywhere from 8-10 hours. It became not only a game of strategies but also of endurance because players would try to stall and exhaust one another. In the 1850s, tournament organizers began to innovate to shorten games.Initially, they tried using watches and sand timers. They implemented a system where players paid fines if they were late.Mechanical chess clocks started appearing by the 1880s, foreshadowing the two-faced analogue and digital clocks of the 20th century we now know. Chess clocks are clocks with buttons that consist of two adjacent clocks, one for each player. The clock counts down from an agreed-upon time and stops once the time expires.If the agreed time is 2 hours, each player has a 1-hour game timer to make all their chess moves for the entire game.TypesYou can use two types of chess clocks: the analogue clock and the digital clock.The analogue chess clock has two of the traditional circular face display clocks we know with a minute and hour hand.Digital chess clocks or digital timers come in all shapes and sizes. It can display just the time or have some more details of the game, depending on how advanced it is.PurposeNo matter which one you choose to use, both serve the same purpose of adding time pressure to the game and tracking that.UsageThe clocks or timers don’t run simultaneously. Instead, when either player presses a button to make a move, the other player pauses his/her clock.Essentially, after making your move, you push the button on your clock to track the time you spent in your turn.Pushing the button on your chess clock stops the time from running on your clock and starts the time on the other clock or your opponent’s.What Is Time Control In Chess?Time control is basically the chess term for agreed time per player for the game. It is how much time each player receives to make all of their moves in the game. They can be simple or complex depending on the type of time control applied.Types Of Time ControlClassical Chess Time ControlUses longer overall time (90 minutes or more)Players are given 120

And then after the 10 seconds, the time that was left previously will begin to countdown this will continue until the allotted time runs out.The time delay is being set for 5 or 10 seconds depending on the chess tournament itself.28. Chess clock increment timing controlThis type of setup is one of the most common types of timing modes used in chess tournaments.The chess clock will start as standard countdown timer but after every move and press of a button, additional time will be seen to the timer.If for example, the increment setup that was given is 20 seconds, that 20 seconds will be added to the remaining time after hitting the button of a chess clock.In tournaments, the increment time that can be given is 30 seconds.That would be an excellent addition to your chess clock timer, more time to think of an excellent move.29. Chess clock blitz chess timing controlThis type of game is quite a fast-paced game; you can have at least a minimum of 5 minutes in one gameplay of chess.Blitz chess game can be distinguished by having the chess clock set to less than 10 minutes.A less than 10 minutes chess game is considered a blitz chess game. This type of timing mode does have an increment feature on its chess clock.For its increment option, the most common would be not less than 2 seconds.30. Chess clock bullet chess timing controlThe bullet chess type of timing modes in chess clock is set for at least less than two minutes…This is a fast-paced chess game, faster than the blitz chess timing mode.There is an increment or delay timing mode setup with a bullet chess game. The increment or delay setup for bullet chess is found to be not less than 1 second.Chess notation is no longer applicable for this type of chess game.31. Chess clock quick chess timing controlThis type of chess timing modes is widely used in chess clubs, and the quick chess setup is typically played with the timing of more than 10 minutes.You can check out chess clubs and some chess tournaments playing even more than 60 minutes.I don't know if I can play that long, but I find it more convenient to play between 15-20 minutes online.32. Chess clock standard chess timing controlThis is the type of chess game that I am used to playing, and the standard chess timing can be set to more than 30 minutes.The rating of a chess player can be affected if, for instance, the timing is more than the Quick chess timing control. I haven't seen any other apparent explanation about this but this type of time control overlaps will have a change on your chess ratings.33. Chess clock multiple time controlThis type of chess time control can be explained by following the common multiple time control for FIDE rules of 90 minutes for the first forty moves and then followed by 30 minutes for the rest of the game.And then after an increment of 30.
