A chess opening or simply an opening refers to the initial moves of a chess game. The term can refer to the initial moves by either side, White or Black, but an opening by Black may also be known as a defense. There are dozens of different openings, and hundreds of variants. The Oxford Companion to Chess lists 1,327 named openings and variants. These vary widely in character from quiet positional play to wild tactical play. In addition to referring to specific move sequences, the opening is the first phase of a chess game, the other phases being the middlegame and the endgame.
Opening moves that are considered standard (often catalogued in a reference work such as the Encyclopaedia of Chess Openings) are referred to as "book moves", or simply "book". Reference works often present move sequences in simple algebraic notation, opening trees, or theory tables. When a game begins to deviate from known opening theory, the players are said to be "out of book". In some opening lines, the moves considered best for both sides have been worked out for twenty to twenty-five moves or more. Some analysis goes to thirty or thirty-five moves, as in the classical King's Indian Defense and in the Najdorf variation of the Sicilian Defense.
Professional chess players spend years studying openings, and continue doing so throughout their careers, as opening theory continues to evolve. Players at the club level also study openings but the importance of the opening phase is smaller there since games are rarely decided in the opening. The study of openings can become unbalanced if it is to the exclusion of tactical training and middlegame and endgame strategy.
A new sequence of moves in the opening is referred to as a theoretical novelty. When kept secret until used in a competitive game it is often known as a prepared variation, a powerful weapon in top-class competition.
Book moves are conventional moves. If you know several conventional openings or book moves, you can quickly and easily plan appropriate responses, an important consideration in blitz games. In addition, you can anticipate how an opponent will respond to your move. In essence, the number of book moves indicates how much theory was known by the players in a specific game—this knowledge is incredibly important when analyzing your games, as it gives you insight into where your opening knowledge ended and tells you exactly where you should start studying your openings.
The following moves are example of a Spanish game. (Ruy López Opening: Morphy Defense, Caro, Graz Variation)
The ECO Codes is a classification system for the chess openings moves. Below is a list of chess openings organized by the Encyclopaedia of Chess Openings (ECO) code. The openings are divided in five volumes labeled from "A" through "E".
