Now time to face a long theorical opening. This opening play a lot by Karpov, Anand and topalov. The black top player are sokolov and Kochnoi.

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-1800s 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.
In the Open Defence, 3...a6 4.Ba4 Nf6 5.0-0 Nxe4, Black tries to make use of the time White will take to regain the pawn to gain a foothold in the centre, with play usually continuing 6.d4 b5 7.Bb3 d5 8.dxe5 Be6. Here 8.Nxe5, once adopted by Fischer, is much less often seen, and Black should equalise after the accurate 8....Nxe5 9.dxe5 c6, which avoids prematurely committing the light-squared bishop and solidly defends d5, often a problem in the Open.
White has a variety of options at move nine, including 9.c3, 9.Be3, 9.Qe2 and 9.Nbd2.
Karpov's move, 9.Nbd2, limits Black's options. In the 1978 Karpov–Korchnoi World Chess Championship match, following 9.Nbd2 Nc5 10.c3 d4 (10...Be7 is an old move that remains popular) Karpov introduced the surprising 11.Ng5!?, a move suggested by his trainer, Igor Zaitsev. If Black takes the knight with 11...Qxg5 White regains the material with 12.Qf3. This variation played a decisive role in a later World Championship match, Kasparov–Anand 1995, when Anand was unable to successfully defend as Black.
