The Ruy Lopez Main Lines, arise (with a few exceptions for move order and such) after 1 e4 e5 Nf3 Nc6 3 Bb5 a6 4 Ba4 Nf6 5 0-0. Some of the lines are incredibly theoretical, but rather than burden you with a ton of theory in lines you will have limited chance of using in your own games, the emphasis in this book is on the lines that are more likely to occur in your games.

Confronting the Sicilian on Your Own terms
The Sicilian jungle is vast. Unless you have a massive amount of time on your hands, it is an exhausting task to keep a sharp opening repertoire together against Black's numerous possibilities. It does not mean that it is impossible, nor does it mean that you shouldn't do it. But for the average player with an average amount of time available for chess studies, it is important to pick the right battles. This is where our weapon, the Chameleon Sicilian, comes in handy.

The Najdorf Sicilian, which arises after 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 has been and continues to be a tremendously popular opening at all levels. It is sharp, unbalanced, with many theory-laden lines - and fun. The main lines after 6 Bg5 e6 7 f4 are steeped in theory, making them tricky to play, especially for players with limited time to study.
