History Of Ruy Lopez Opening
The opening is named after the 16th century Spanish priest Ruy López de Segura, who made a systematic study of this and other openings in the 150-page book on chess Libro del Ajedrez written in 1561. Though it bears his name, this particular opening was included in the Göttingen manuscript, which dates from around 1490. Popular use of the Ruy Lopez opening did not develop, however, until the mid-19th century when Carl Jaenisch, a Russian theoretician, "rediscovered" its potential. The opening remains the most commonly used amongst the open games in master play; it has been adopted by almost all players during their careers, many of whom have played it with both colours. Due to the difficulty imposed on Black's player, and the fact that Lopez was a priest during the Inquisition, a common nickname for the opening is "The Spanish Torture".
