It covers a complete White repertoire built around the Catalan, plus all key replies you’ll face: Slav, QGA, Benoni, Englund, Queen’s Indian, Old Indian, Grünfeld, King’s Indian, and Dutch.

For Black, it includes a full French Defense package (with all main sidelines) and the QGD Tartakower, both in the main line and against the London and other sidelines.

To show you the style of this repertoire, let’s look at one piece of it - the Catalan. Your plan is simple:

1. Take control of the center with d4 and c4
2. Castle kingside with Nf3, g3, Bg2, 0-0
3. Develop the queenside (often Nbd2, Qc2, b3, Bb2)
4. Break in the center with e4 and start your attack
