The Ruy Lopez Powerbook 2025 is a comprehensive special book with which you can check your opening lines and set out on a search for promising additions to your repertoire. For this new edition of the Ruy Lopez Powerbook 2025 once again only games from the engine room of playcess.com were used. The enormous total of 3.66 million Ruy Lopez games allows for meaningful statistical analyses not only for the main lines but also for numerous side variations. A must for all Ruy Lopez players! The Ruy Lopez Powerbook 2025 is an opening book which you can use with your Fritz or ChessBase program. It does not contain a database – i.e. no games are supplied with it.
The Marshall Attack is analysed so deeply that it can be reckoned to be a reliable drawing weapon for Black, that is especially true in the engine room. To avoid it 6.d3 b5 7.Bb3 is becoming more and more popular (after...a6 4.Ba4 Nf6 5.0-0 Be7).
Somewhat surprisingly there is now in the engine room a clear preference for 7...Bb7, whereas in humanoid chess 7...d6 is the move of the top players and also clearly the most frequently played. The Powerbook allows interesting studies with the bishop move.
The Spanish Opening is one of the absolutely oldest. It is named after the Spanish priest Ruy López de Segura, who in 1561 presented his analyses on this way of starting the game in a book. But even today the Spanish can be seen in many games of top players and it is quite clearly the most important of the Open Games. Not only does White develop his bishop, he also immediately puts pressure on the black e5-pawn. Whereas previously 3...a6 was almost obligatory, nowadays 3...Nf6 – the Berlin Defence – is favoured.
