Time trouble

Last updated

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. [1]


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. [2]

In time trouble, players are usually focused on maintaining the integrity of their position. Lars Bo Hansen's principles are to ensure that pieces remain protected, avoid unnecessary pawn moves, and avoid analyzing unnecessary tactics. [1] Webb advises players to keep track of the number of moves played, and work out a provisional response to each of the opponent's moves on the opponent's time. [2] This trick is called "permanent brain" or "pondering". When the opponent is in time trouble, Webb advocated the barrage technique which involves planning two or more moves ahead, and then playing them in rapid succession. The idea is to give the opponent little time to prepare for the second move, increasing the probability of that move being a mistake. Playing a barrage of moves does increase the chance of a blunder from the barrager as well, and the technique is inadvisable in a winning position where a player should focus on winning on the board. [2]

Rules governing time trouble

FIDE has some additional rules regarding players in time trouble.

The first rule regards the recording of moves. A player with less than five minutes remaining, in a game where there is not a 30-second or greater time increment per move, is not required to keep score as usual. However, if the player makes the time control, he must update the scoresheet before making a move as soon as the flag falls, marking expiry of the first, and now passed, time control. If only one player is in time trouble and not recording moves, the opponent's scoresheet may be used to update the score. In the case of mutual time pressure, where both players have stopped recording the moves, the tournament director or an assistant should be on hand to record the moves as they are played, and their notes can be used to update the scoresheets upon passage of the time control. If the game score is not recorded by anybody during the time pressure period, the players shall endeavor to reconstruct the moves of the game, under the control of the tournament director; if this is not possible the game continues with the next move being regarded as the first move of the next time control. [3]

The second rule regards the arbiter's possibility of ending a game as drawn due to a player's lack of effort in winning the game by "normal means". Occasionally it happens in a sudden death time control without increments that a player has trouble in physically executing an indefinite series of moves in the time remaining. The opponent could try playing on this, and continue to play on in the hopes of winning by time forfeit, rather than by winning the position on the board. To prevent this FIDE allows tournament organizers to apply the guidelines in articles III.4 or III.5. [4] A tournament played with article III.4 allows a player with less than two minutes remaining to summon the arbiter and request that a five-second increment be introduced. Invoking III.4 constitutes a draw offer which the opponent may accept. Otherwise, if the arbiter agrees to introduce the increment, the opponent is awarded two minutes in addition to the increment. In a tournament played with article III.5 a player with less than two minutes may summon an arbiter and request that the game be declared drawn "on the basis that his opponent cannot win by normal means, and/or that his opponent has been making no effort to win by normal means". The arbiter may accept the claim (which ends the game immediately as a draw), reject the claim (after which the game continues, with the opponent receiving two additional minutes), or postpone the decision. In this case the opponent may be given two minutes extra, and the game continues until the arbiter makes a call or the claimant's flag falls after which the arbiter makes a decision.

The rules allowing an arbiter to declare a game drawn do not apply to blitz chess. Several high level blitz tournaments, such as the 2009 World Blitz Championship, are played with a two-second increment which allows players time to execute moves and discourages attempts to win on time in trivially drawn positions such as king and knight versus king and knight. [5]

US Chess version

Tournaments governed under the rules of the United States Chess Federation have a similar rule to FIDE's guidelines that can be used if this variation is announced beforehand, called the "insufficient losing chances" rule. A player with less than two minutes remaining without time delay or increment can petition the tournament director for a draw on the grounds that the opponent has no reasonable chance of winning the position, had both players had ample time. In US Chess guidelines, this would mean an average tournament player (class C) having a less than a 10% probability of losing the position against a master, with both players having sufficient time. The tournament director may accept the claim (ending the game as drawn), reject the claim and penalize the claimant with one minute less time, or postpone the decision. If the tournament director postpones the decision, there is the option of substituting a non-delay clock with a delay clock with the claimant having his remaining time halved. Since the insufficient losing chances rules calls upon discretion from the tournament director, clocks with the time delay or increment feature are preferred over clocks without them.

Chess clock Two adjacent clocks with stop/start buttons

A chess clock consists of two adjacent clocks with buttons to stop one clock while starting the other, so that the two clocks never run simultaneously. Chess clocks are used in chess and other two-player games where the players move in turn, and in some legal settings where each side is allotted a specific amount of time for arguments. The purpose is to keep track of the total time each player takes for their own moves, and ensure that neither player overly delays the game.

Rules of chess Rules of play for the game of chess

The rules of chess govern the play of the game of chess. While the exact origins of chess are unclear, modern rules first took form during the Middle Ages. The rules continued to be slightly modified until the early 19th century, when they reached essentially their current form. The rules also varied somewhat from place to place. Today, the standard rules are set by FIDE, the international governing body for chess. Slight modifications are made by some national organizations for their own purposes. There are variations of the rules for fast chess, correspondence chess, online chess, and Chess960.

Time control Mechanism used in chess

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. Time controls are typically enforced by means of a game clock, where the times below are given per player. Time pressure is the situation of having very little time on a player's clock to complete their remaining moves.

The fifty-move rule in chess states that a player can claim a draw if no capture has been made and no pawn has been moved in the last fifty moves. The purpose of this rule is to prevent a player with no chance of winning from obstinately continuing to play indefinitely or seeking to win by tiring the opponent.

In chess, there are a number of ways that a game can end in a draw, neither player winning. Draws are codified by various rules of chess including stalemate, threefold repetition, and the fifty-move rule. Under the standard FIDE rules, a draw also occurs in a "dead position", when no sequence of legal moves can lead to checkmate, most commonly when neither player has sufficient material to checkmate the opponent.

In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times during the game. The rule is also known as repetition of position and, in the USCF rules, as triple occurrence of position. Two positions are by definition "the same" if the same types of pieces occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture en passant is the same. The repeated positions need not occur in succession. The reasoning behind the rule is that if the position occurs three times, no real progress is being made and the game could hypothetically continue indefinitely.

A game of chess can end in a draw by agreement. A player may offer a draw at any stage of a game; if the opponent accepts, the game is a draw. The majority of draws in chess are by agreement.

Fast chess Chess variant with little move time allowed

Fast chess is a type of chess in which each player is given less time to consider their moves than normal tournament time controls allow. Fast chess is subdivided, by decreasing time controls, into rapid chess, blitz chess, and bullet chess. Armageddon chess is a particular variation of fast chess in which different rules apply for each of the two players.

Promotion (chess) A rule in chess

In chess, promotion is the replacement of a pawn with a new queen, rook, bishop, or knight of the same color. It occurs immediately when the pawn moves to its last rank, with the player choosing the piece of promotion. The new piece does not have to be a previously captured piece. Promotion is mandatory; the pawn cannot remain as a pawn.

In chess, a blunder is a critically bad move. It is usually caused by some tactical oversight, whether it be from time trouble, overconfidence or carelessness. Although blunders are more common in amateur games, all human players make them, even at the world championship level. Creating opportunities for the opponent to blunder is an important skill in over the board chess.

Cheating in chess is a deliberate violation of the rules of chess or other behaviour that is intended to give an unfair advantage to a player or team. Cheating can occur in many forms and can take place before, during, or after a game. Commonly cited instances of cheating include: collusion with spectators or other players, use of chess engines during play, rating manipulation, and violations of the touch-move rule. Many suspiciously motivated practices are not comprehensively covered by the rules of chess. On ethical or moral grounds only, such practices may be judged by some as acceptable, and by others as cheating.

The current world blitz champion is the French grandmaster Maxime Vachier-Lagrave. Bibisara Assaubayeva from Kazakhstan is the current women's blitz world champion.

The World Rapid Chess Championship is a chess tournament held to determine the world champion in chess played under rapid time controls. Prior to 2012, FIDE gave such recognition to a limited number of tournaments, with non-FIDE recognized tournaments annually naming a world rapid champion of their own. Since 2012, FIDE has held an annual joint rapid and blitz chess tournament and billed it as the World Rapid & Blitz Chess Championships. FIDE also holds the Women's World Rapid & Blitz Chess Championship. The current rapid world champion is the Uzbek grandmaster Nodirbek Abdusattorov. Alexandra Kosteniuk from Russia is the current women's rapid world champion.

Some board games, such as chess and Go, use an adjournment mechanism to suspend the game in progress so it can be continued at another time, typically the following day. The rationale is that games often extend in duration beyond what is reasonable for a single session of play. There may be a sealed move: the next move that would be made is sealed in an envelope, to be played out when the game resumes. This practice ensures that neither player knows what the board position will be when it is their next turn to move.
