Cf. relative pin.  \nactive 1. Describes a piece that controls a number of squares, or a piece that has a number of squares available for its next move.  \n2. An “active defense” is a defense employing threat(s) or counterattack(s) .  \nAntonym: passive.  \nEnvelope used for the adjournment of a match game Efim Geller vs. Bent Larsen, Copenhagen 1966  \nadjournment Suspension of a chess game with the intention to finish it later. It was once very common in high-level competition, often occurring soon after the first time control, but the practice has been abandoned due to the advent of computer analysis. See sealed move.  \nadjudication Decision by a strong chess player (the adjudicator) on the outcome of an unfinished game.  \n2 2 B  \nThis practice is now uncommon in over-the-board events, but does happen in online chess when one player refuses to continue after an adjournment.  \nadjust (see Touch-move rule) To adjust the position of a piece on its square without being required to move it. A player may only do this on his turn to move, and he must first say “I adjust”, or the French equivalent \"J'adoube\" .  \nadvanced pawn A pawn that is on the opponent’s side of the board (the fifth rank or higher) . An advanced pawn maybe weak if it is overextended, lacking support and difficult to defend, or strong if it cramps the enemy by limiting mobility. An advanced passed pawn that threatens to promote can be especially strong.  \nadvantage A better position with the chance of winning the game. Evaluation factors can include space, time, material, and threats.  \nAlekhine vs. Nimzowitsch, 1930  \nAlekhine’s gun  \nAlekhine’s gun A formation in which a queen backs up two rooks on the same file.  \nalgebraic notation The standard way to record the moves of a chess game, using alphanumeric coordinates for the squares.  \namateur The distinction between professional and amateur is not very important in chess as amateurs may win prizes, accept appearance fees, and earn any title, including World Champion. In the 19th century,“Amateur” was sometimes used in published game scores to conceal the name of the losing player in a Master vs. Amateur contest. It was thought to be impolite to use a player’s name without permission, and the professional did not want to risk losing a customer. See also NNor N.N.  \nanalysis The study of a position to determine best play for both sides.  \nannotation Written commentary on a game using a combination of comments, chess symbols or notation.  \nannounced mate A practice, common in the 19th century, whereby a player would announce a sequence of moves, believed by him to constitute best play by both sides, that led to a forced checkmate for the announcing player in a specified number of moves (for example,“mate in five”) .  \nantipositional A move or a plan that is not in accordance with the principles of positional play. Antipositional is used to describe moves that are part of an incorrect plan rather than a mistake made when trying to follow a correct plan. Antipositional moves  \nare often pawn moves; since pawns cannot move backwards to return to squares they have left, their advance often creates irreparable weaknesses.  \nAnti-Sicilian A","cbCaikU0JFAZ592Y","https://ap.wps.com/l/cbCaikU0JFAZ592Y","pdf",833596,29,"English","# Glossary entries (A-Z)\n## A-D\n## E-H\n## I-L\n## M-P\n## Q-T\n## U-Z\n# References","[{\"question\":\"What is the purpose of this chess glossary?\",\"answer\":\"It explains commonly used chess terms in alphabetical order, linking related concepts to dedicated entries such as specific problem terms or chess variants.\"},{\"question\":\"How are terms organized in the glossary?\",\"answer\":\"Entries are arranged alphabetically by term, with page references and cross-references for related topics.\"},{\"question\":\"Does the glossary include both rules and strategy concepts?\",\"answer\":\"Yes.
