Rules

FIDE tournaments are held according to the FIDE handbook rules, which is used as a basic guide for many chess tournaments. The handbook contains nine articles dealing with chess competitions.

The chess clock

A chess clock is a clock with two separate time displays of which only one display can be running at a time. The player with the black pieces
White and Black in chess

 will have their timer running first, and will make the first move. The player or the arbiter may end the game at any time after the player's opponent has oversteped their time limit. If a timed out clock remains unnoticed, the game will continue as normal. If the game needs to be interrupted, the arbiter shall stop the clock.

Irregularities

If it is found that the starting position of the pieces is incorrect, the game must be cancelled and restarted. If it is found that an illegal move has been made, the game must return to the position directly before the irregularity. For the first two illegal moves by a player, the arbiter shall give two minutes extra time to his opponent each time. If a player is to make a third illegal move in the same game, the arbiter can declare the game lost by the offending player. If a game begins with the piece colors

 reversed, the game should be stopped and restarted unless an arbiter rules otherwise. If a player displaces any pieces, they should place them in the correct locations on their own time.

The recording of moves

. However, if a player reaches less than five minutes on their clock, and does not have a time delay of thirty seconds or more, they are excused from recording the remaining game moves until the game has been completed. At the conclusion of the game, both players must sign each other's scoresheets and turn them to the event organizers if instructed to do so. In fast chess games, players are not required to record moves, as it would take away from important thinking time. The scoresheets must be visible to the arbiter at all times. Each player must be familiar with the following chess abbreviations
Punctuation (chess)

Draw (chess)
In chess, a draw is when a game ends in a tie. It is one of the possible outcomes of a game, along with a win for White and a win for Black . Usually, in tournaments a draw is worth a half point to each player, while a win is worth one point to the victor and none to the loser.For the most part,...

 according to the rules of chess, the player is allowed to stop both clocks and record the draw claim as long as his or her opponent agrees to the claim. If the opponent disputes the draw claim the director may be called to come to a conclusion. If the claim is found to be correct, the game is drawn. Once a player has made a move from a position eligible for a draw, they lose their rights to claim a draw on that position.

Quickplay finish

The quickplay finish is the phase of the game when all remaining moves must be made in a limited time. If a player has two minutes or less left on their clock, they may ask the arbiter to adjudicate a draw. The arbiter must decide if the player's opponent is making any attempt to win the game by normal means, or if the position can be won in any way. If the arbiter decides against a draw, the player's opponent will be awarded two extra minutes of time. Otherwise, the game is drawn, and the decision of the arbiter is final.

Players are granted one point (1) for a win, a half (½) point for a draw, and no points (0) for a loss toward their tournament score, unless otherwise stated by the tournament director beforehand. Full-point byes are received when a player is excluded from a round because of an extra player. Thus, in tournaments with an odd number of players, a different player will receive a full-point each round. A full-point bye is equal in points to a normal win. Half-point byes can be requested by a player who will be unavailable for a round. If accepted, the player will receive a half-point, as if they had drawn the game. A player who wins by forfeit or default will also be granted one point. Players may use the following format to record the game score:

Player conduct

Players are not allowed to take any action that will bring the game into disrepute. For example, deliberate attempts at cheating by sneaking a captured piece back on to the board can be punished by this rule, rather than the rules dealing with illegal moves.

Players can not make any use of any outside information. This includes advice, notes, and analysis of another chess board. Electronic devices are not to be used in the tournament area unless approved by the arbiter. If a player's mobile phone

Once a player has finished their game, they are considered a spectator. Refusal of a player to comply with the rules may result in penalty. If two opponents both refuse to obey the rules, the game may be considered lost by both players. In 1976, smoking

 job is to see that the Laws of Chess are observed and make decisions in the best interest of the competition, but must not interfere with the game otherwise. If a rule is broken, the arbiter may choose from a number of penalties including the following:
  • warning the offending player
  • increasing the remaining time of the opponent
  • reducing the remaining time of the offending player
  • declaring a game to be lost
  • reducing the points scored in a game by the offending player
  • increasing the points scored in a game by the opponent
  • expulsion of the offending a player from the event

The arbiter may also expel offending spectators from the venue. Spectators are also forbidden to use mobile phones at any time in the playing area, and may be expelled for it. Member federations are allowed to ask FIDE authorities to give an official decision about problems relating to the Laws of Chess.

Tournament categories

FIDE classifies tournaments according to the average Elo rating of the participants. The starting category for master-level tournaments is category I, which applies to a tournament whose participants have an average Elo rating from 2251 to 2275. From 2276 to 2300 it is a category II tournament, and so on with a further category every 25 points. The strongest tournaments to date have included a category XXI section.

A time control is a mechanism in tournament play that allows each round of the match to finish in a timely fashion so that the tournament can proceed. The three main types of time controls used in chess tournaments are blitz, standard, and compensation.

Blitz

In blitz chess
Blitz chess
Fast chess, also known as blitz chess, lightning chess, sudden death, speed chess, bullet chess and rapid chess, is a type of chess game in which each side is given less time to make their moves than under the normal tournament time controls of 60 to 180 minutes per player.-Overview:The different...

 (also known as sudden death chess) each player starts with a fixed amount of time to spend on their moves of the game. The FIDE Handbook designates the following common blitz time controls:
  • Bullet: one or two minutes per side
  • Blitz: less than 15 minutes per side (often 5 minutes), sometimes with a small time increment every move
  • Rapid: 15–60 minutes per side (often 25 minutes), sometimes with a small time increment every move.
  • Armageddon: a single game guaranteed to produce a result, because the Black side has draw odds (that is, for Black, a draw is equal to a victory). To compensate, White has more time on the clock.

Blitz time controls increase the odds that one would "lose on time", meaning a forfeiture of the game due to the expiration of one's chess clock. Blitz tournaments are often documented with the notation "G/5" of "G/15", meaning "game in 5" and "game in 15", respectively.

Standard

Standard time controls (STC) are one's in which a player has a set amount of time to complete a specified number of moves. If the specified number of moves is met, the player's time will rejuvenate. The first standard time controls, introduced in 1861, were 24 moves in two hours, with the average game lasting five hours. In the mid-1980s, a new format, 40 moves in two hours, proved popular because few games lasted over 60 moves.

Compensation

Compensation (also known as incremental or delay) time control methods require the use a special clock, called a delay clock. There are two main forms which provide compensation for both the time lost in physically making a move and to make it such that a player can avoid having an ever-decreasing amount of time remaining.

    . When it becomes a player's turn to move, the clock waits for the delay period before starting to subtract from the player's remaining time. For example, if the delay is five seconds, the clock waits for five seconds before counting down. The time is not accumulated. If the player moves within the delay period, no time is subtracted from his remaining time.
  • Fischer delay, invented by Bobby Fischer

    . When it becomes a player's turn to move, the delay is added to the player's remaining time. For example, if the delay is five seconds and the player has ten minutes remaining on his clock, when his clock is activated, he now has ten minutes and five seconds remaining. Time can be accumulated, so if the player moves within the delay period, his remaining time actually increases. This style of time control is common on internet chess server

    s, where the delay is termed an "increment".

Prizes

The winners of chess tournaments are often rewarded with monetary prizes. Often, the chess tournament draws its prizes from a prize fund, from which all the winners in each section are rewarded. For example, the 2008 World Open chess tournament
