Statistics
[edit]Moves | 1800–1900 | 1901–1935 | 1935–1998 |
---|---|---|---|
1. e4 e5 | 63% | 31% | 15% |

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]
