This time though I have focused mainly on Colle-Zukertort type positions, plus some transpositions to Queen’s Indian-type play, so this is not a repertoire book like the previous one, but rather you can look at it as an opening book. Of course, Slav re- actions with …c6 are covered as well, and also early and quick …c5 and …g6 reac- tions. Due to increased popularity, I have dived into specifics which we can consider now as a renaissance of this old line. Another important thing, and it is indeed an especially important detail, is the or- ganization of material into logical sections, because this system is often transposi- tional. Therefore, it is important to do this because reading this book should be an easy and joyful experience. There are positions in this book that have stood the test of time, but I have also focused on the most recent ideas as I didn’t want to simply repeat the same ideas as before – I wanted to include as much as possible new plans. I also tested these ideas numerous times in my own practice. Milos Pavlovic, December 2024.
