The touch-move rule in chess determines that, if a player deliberately touches a piece on the board when it is his turn to move, then he or she must move or capture the piece if it is legitimate to do so. If it is part of the player touched, it must be moved if he has a legal move. If the opponent's part is touched, it must be arrested if it can be arrested by legal action. This is a chess rule that applies to all games that are played formally There is a separate rule that players who release a piece after making a legal move can not retract that step.

Detail
If a player moves deliberately touching one of their pieces, he must move it if it can be moved legally. As long as the hand leaves no chunks on the new box, the latter can be placed on any accessible box. Accidentally touch a piece, e.g. brushing it while grabbing other parts, does not count as a deliberate touch.
If a player touches an unfriendly part, then he or she should catch it if it can be caught. If a player touches one of its parts and the opposing part, he or she should make the catch if it is a legal action. Otherwise, he must move or catch the first piece they touch. If it can not be determined whether he touched his own piece or his opponent's pieces first, it is assumed that he touched his own piece first. If a player touches more than one section, he or she must move or capture the first piece that can be moved or captured legally. The exception to that is the trial of illegal caster; in this case the king should be moved if possible, but otherwise there is no requirement to move the castle.
When castrated, the king must be the first part touched. If a player touches his fortress at the same time as touching the king, he must dwell with the castle if it is legal to do so. If the player completes two square kings move without touching the castle, the player must move the correct castle accordingly if the drill on that side is legal. Otherwise, the move should be withdrawn and the other king moved.
When the pawn is moved to the eight rank , after the player releases his hand from mortgaging, the movement different pions can no longer be replaced. However, the move was not complete until the promoted part was released on the square (Just & amp; Burg 2003: 20-23).
Example
In the diagram, from the match between the future world champion Bobby Fischer and Jan Hein Donner, White has a winning advantage; Black has just moved 29... Qg5-f5 and White fell for a trick. Fischer touches his bishop, intending to move 30.Bd3, which looks like a natural movement, but then realizes that Black can play 30... Rxc2, and after 31.Bxf5 Rc1 32.Qxc1 Bxc1, the game will be a series, because the bishop is in conflict opposite. After touching the bishop, he realized that 30.Bd3 was a bad move, but because he was obliged to move the bishop, and the other bishops' movements were even worse, after a few seconds he played 30.Bd3. The queens and rooks are exchanged (as above) and a draw based on the agreement is reached after step 34. Had Fischer won the match, he would be tied to Boris Spassky for first place in the 1966 Piatigorsky Cup tournament (Kashdan 1968: 49-50).
The touch-move rule resulted in a worse outcome for Fischer in his game as Black against Wolfgang Unzicker in Buenos Aires 1960. In the position depicted, Fischer touched his pawn, intending to play 12... h6. He then realizes that White can only play 13.Bxh6, since 13... gxh6 will be illegal because the pin on g- file by queen White. After touching his h-pawn, the touch-move rules require Fischer to play either 12... h6 ?? or 12... h5 ??, almost equally bad movements that fatally weaken Black's kingside . Fischer suit plays 12... h5 ?? and resigned only ten steps later - his shortest loss in a serious match (Mednis 1997: 110-11).
In this position in the fast-paced game between former world champion Anatoly Karpov and Alexander Chernin in Tilburg in 1992, White had just promoted the pawn to the queen on the square. Black makes checks found 53... Kd6. Karpov, with very little time left, did not see that he was in check and played an illegal step 54.Qe6. The arbitrator requires Karpov to play a legal action with his queen instead (since he touched it), and he chose 54.Qe7 ?? (54.Qd7 Rxd7 55.Kg6 will still be withdrawn (Fox & James 1993: 198)). After 54... Rxe7, Karpov lost the game (McDonald 2002: 224-25).
In 1889 the match between Siegbert Tarrasch and Semyon Alapin in Breslau, Alapin expects 5.d4, a normal step after 1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 in Defense Petrov. But when he sees the position he has touched bishop king , intend 5.. Be7 replied to 5.d4, not realizing that White is actually playing 5.d3 attacking his knights. Now forced to move the bishop, he will lose his knight without compensation, so soon resigns (Chernev & Reinfeld 1949: 111).

Customize snippets
If a player wants to customize pieces in their box without being asked to move or catch a snippet, players can announce j'adoube [? a'dub] , (in French: I customize ), or words for that effect in another language. J'adoube is internationally recognized by chess players as announcing intent to make incidental contact with their work.
This phrase is used to give a player a warning to his opponent that the player will touch a section on the board, usually to center it on the square, with no intention of moving with it. Although the French term is customary, it is not mandatory; Other similar indications may be used. A player can customize a piece in this way only when it is his turn to move.
Examples of abuse
There are times in the history of chess when a player has pronounced j'adoube after a losing movement to pull it back, so it tries to avoid moving rules. Such behavior is regarded as cheating (see cheats in chess). Grandmaster of Yugoslavia, Milan Matulovi? nicknamed "J'adoubovic" after such an event (Hooper & amp; Whyld 1992: 185,252) (Lombardy & Daniels 1975: 104).
History
The touch-move rule has been around for centuries. In the Middle Ages strict rules were deemed necessary because chess was played for bets. Luis Ramirez de Lucena rules in his 1497 Arte de Axdres (Sunnucks 1970: 462). Benjamin Franklin called it in his 1786 essay The chess morals (Truzzi 1974: 14). At one time the rules also require players who play illegal acts to move their king. In the first half of the nineteenth century, Rule XIII of the London Chess Club provided:
If a player is doing the wrong move, is. , play a Piece or Pawn into any box that can not be legally moved, the opponent has a choice of three penalties; viz., 1, forcing him to let Piece or Pawn remain in the square where he plays it; 2, to move to another square correctly; 3, to replace Piece or Pawn and move the King. (Staunton 1848: 37) (Marache 1866: 24)
While this rule exists, it sometimes causes such tragediomedies in the 1893 game between Lindermann and Echtermeyer, in Kiel. In the game, after 1.e4 d5 2.exd5 Qxd5 White, probably intend regular 3.Nc3, instead put queen bishop on c3. Because the move was illegal, White was forced to move his king instead. After forced 3.Ke2 ??, Black gives a check with 3... Qe4 # (Chernev 1974: 119).
