Time Trouble
In chess played with a time control, time trouble, time pressure, or its German translation ''Zeitnot'', is the situation where a player has little time to complete the required moves. When forced to play quickly, the probability of making blunders is increased, so handling the clock is an important aspect of chess playing. The last move of the time control (often move 40) is especially prone to blunders if players only have a few seconds to play it, and many games have been lost due to poor time management in time pressure. Practical aspects Players often spend large amounts of time after the opening as they consider their plans and calculate various tactical variations. In many cases, spending this time to find the correct path is worth the risk of time trouble later on if the position is simplified to a point where it can be played quickly. However, spending large amounts of time in simple positions on non-forcing matters is often excessive. In time trouble, players are usuall ...

Time Control
A time control is a mechanism in the tournament play of almost all two-player board games so that each round of the match can finish in a timely way and the tournament can proceed. For turn-based games such as chess, shogi or go, time controls are typically enforced by means of a game clock, which counts time spent on each player's turn separately. A player that spends more time than the time control allows is penalized, usually by the loss of the game. Time pressure (or time trouble or ''Zeitnot'') is the situation where one player has very little time on their clock to complete their remaining moves. Classification The amount of time given to each player to complete their moves will vary from game to game. However, most games tend to change the classification of tournaments according to the length of time given to the players. In chess, various classification schemes are used. FIDE defines time controls based on the sum of the amount of time allotted to each player, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blunder (chess)
In chess, a blunder is a critically bad mistake that severely worsens the player's position by allowing a loss of , checkmate, or anything similar. It is usually caused by some tactical oversight, whether due to time trouble, overconfidence, or carelessness. Although blunders are most common in beginner games, all human players make them, even at the world championship level. Creating opportunities for the opponent to blunder is an important skill in chess. What qualifies as a blunder rather than a normal mistake is somewhat subjective. A weak move from a novice player might be explained by the player's lack of skill, while the same move from a master might be called a blunder. In chess annotation, blunders are typically marked with two question marks ("??") after the move notation. Especially among amateur and novice players, blunders often occur because of a faulty thought process where players do not consider the opponent's . In particular, checks, , and need to be considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Professional chess players spend years studying openings, and they continue doing so throughout their careers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permanent Brain
In turn-based games, permanent brain (also called pondering) is the act of thinking during the opponent's turn. Chess engines that continue calculating even when it is not their turn to play end up choosing moves that are stronger than if they are barred from calculating on their opponent's turn. Use with chess programs The strength of chess programs depends very much on the amount of time allocated for calculating. Many chess programs use pondering to improve their strength. Current programs cannot create strategic plans, so a program simply tries to predict the opponent's move and begins to calculate its response. If the opponent's move has been guessed correctly, then the program continues to calculate. If the prediction fails, the program begins a new computation. Pondering is less effective than normal thinking. For example, if the program guesses 25% of the opponent's moves correctly, the use of pondering is on average equivalent to increasing the normal calculating time b ...

Game Clock
A chess clock is a device that comprises two adjacent clocks with buttons to stop one clock while starting the other, so that the two clocks never run simultaneously. The clocks are used in games where the time is allocated between two parties. The purpose is to keep track of the total time each party takes and prevent delays. Parties may take more or less time over any individual move. Chess clocks were first used extensively in tournament chess, beginning with a competition at the London 1883 tournament. They are often called game clocks, as their use has since spread to tournament Scrabble, shogi, Go, and nearly every competitive two-player board game, as well as other types of games. Various designs exist for chess clocks and different methods of time control may be employed on the clocks, with "sudden death" being the simplest.
