Glossary of Chess Terms, Definitions, and Acronyms

Chess has a rich vocabulary with many terms and acronyms ranging from from ACP to Zwischenzug. Here we provide an alphabetical list of chess terms along with their definitions as well as various acronyms and their definitions. It is our intention for this to be the most comprehensive and complete list available on the Internet. Our glossary of terms and acronyms will be updated on a regular basis as our readers inform us of additions.

Glossary of Chess Terms


A B C D E F G-H I-L M-N O P Q-R S T U-Z


[ECO] [Elimination Tournament] [ELO] [Equality] [Endgame] [En Passant] [En Prise] [Exchange] [Exchange, The] [Expert]

Acronym
Encyclopedia of Chess Openings

Side Note
ECO classifies openings using codes from A00 to E99. The codes are in wide use throughout the chess world in a mini-library of five volumes A, B, C, D, E - referring to the five main groups of the classification of openings.



Elimination Tournament [Top]

ELO [Top]

Definition
A mathematical rating system, now used worldwide, to rank chess players.

Side Note
Elo is often written in capital letters, ELO, but it is not an acronym. It is named after its inventor, Arpad Elo (b.1903 Hungary; d.1992 USA). The Elo method was adopted in 1970 by FIDE for rating world class players.



Equality [Top]

Definition
A situation in which neither side has an advantage over the opponent.

Example
Where both Black and White have approximately the same chances to win the game.

Side Note
Equality in a position doesn't mean that the game is necessarily a draw. If the game were continued 100 times from the equal position, both sides could expect an equal number of wins.

See Static Equality and Dynamic Equality



Endgame [Top]

Definition
The endgame is the third and last stage of a chess game. There are few pieces on the board, the Kings are more active, and Pawn promotion is a key objective.



En Passant [Top]

Definition
A French term that literally means “in passing.” When a pawn advances two squares something it can only do if it has not yet moved, and passes an enemy pawn on an adjacent file that has advanced to its fifth rank, it may be captured by that enemy pawn as if the advancing pawn had moved only one square. This optional capture may be made only on the first opportunity, else the right in that instance is permanently lost.

Side Note
See Special Moves - En Passant
