The Ruy Lopez, generally called the Spanish Game outside of English speaking
countries, is a chess opening characterised by the moves:
1. e4, e5 2. Nf3, Nc6 3. Bb5
The Ruy Lopez is one of the most popular openings. It has such a vast number of
variations that in the Encyclopaedia of Chess Openings all codes from C60 to C99
are assigned to them.
The opening is named after the 16th century Spanish priest Ruy López de Segura.
He made a systematic study of this and other openings in the 150-page book on
chess Libro del Ajedrez written in 1561. However, although it is named included in
the Göttingen manuscript, which dates from around 1490. Popular use of the Ruy
Lopez opening did not develop, however, until the mid-1800s when Carl Jaenisch, a
Russian theoretician, "rediscovered" its potential. The opening is still in active use
as the double King's Pawn opening most commonly used in master play; it has
been adopted by almost all players at some point in their careers and many play it
from both the white and black sides.
