List of chess openings

From Wikipedia, the free encyclopedia

This is a list of chess openings, organised by the Encyclopaedia of Chess Openings (ECO) code classification system. The chess openings are categorised into five broad areas ("A" through "E"), with each of those broken up into one hundred subcategories ("00" through "99"). The openings were published in five volumes of ECO, with volumes labeled "A" through "E".

This article uses algebraic notation to describe chess moves.

Statistics

[edit]
Moves 1800–1900 1901–1935 1935–1998
1. e4 e5 63% 31% 15%
1. e4 other 23% 20% 35%
1. d4 d5 10% 28% 15%
1. d4 other 3% 16% 23%
1. other 5% 12%

These statistics show a movement away from symmetrical defences to asymmetrical defences. In particular, in reply to 1.e4, the Sicilian and French defences, and to 1.d4 the Indian defences. Also, particularly amongst strong players, an increased use of the English Opening for White.[1]
