Contrary to what the critical pessimists might say, the Reti opening is an ambitious weapon for White. By avoiding the main theoretical debates, White tries to reach an unbalanced position from an early stage of the game, with many different plans being available. This is exactly what I found attractive when I started to play the Reti.
Because of course, I didn’t always play the Reti. At first, I was a pure 1.d4 player. But on numerous occasions, during my preparations, I felt as if I was stuck and being caught in a dead end. For instance, when I had to investigate very complicated lines (as you encounter in the Slav Defence, but many others as well). I thought that I was far from getting any advantage in these openings. And even if I could manage, the positions reached were very classical, and my opponents most likely under-stood them well. That’s why I started to play 1.Nf3 from time to time, but at first without knowing much theory.
It really came as a breath of fresh airto my chess games, and I enjoyed it. In 2013, I decided to go one step further, and build a complete repertoire for my games with 1.Nf3. I did that with my friend IM Romain Picard. We were in the same spirit (even if he is an 1.e4 player, we could find much common ground with our Reti). Of course, when you leave the center to your opponent, you must be very careful not to end up worse after the opening. But I was satisfied with most of the work we did together. About one year ago, Romain Edouard offered me the possibility to write this book.
It was a real challenge for me. There was no real book available with a complete repertoire for the Reti. Even more challenging, some recently published books included the Reti in refutable «sidelines» for White. But I have always been confident that I could manage to overturn these opinions, and write an interesting book with many new lines and underestimated possibilities. My first principle was, even if White is playing a rather ‘slow’ opening, and he doesn’t take full control over the center, he shouldn’t leave Black’s hands free. Allow him to play both …d5 and …c5 or …d5 and …e5 (you won’t meet many lines where …e5 is played by Black). If Black can manage that, I believe that he will hardly be worse. That’s why I decided to concentrate on the different move-orders where White plays 1.Nf3 and 2.c4 against most of the black moves, putting immediate pressure on d5. That’s also why I consider the most critical debate of this book, to be the ‘Advance Variation’, where Black plays 2…d4, because he will try to take some space, following up with 3…c5, heading for a reversed Benoni. In most of these cases, I have been looking for lines clearly keeping the Reti-spirit, but I sometimes transposed into some 1.d4 lines, when I felt that it was needed or clearly the best choice. So, the first point is that I have chosen lines where White is playing a kingside fianchetto in most cases (especially when Black starts with 1…d5).
And this first fianchetto is often followed by another, if possible. My goal was to reach a middlegame full of subtle resources where White has various ways to react in the center, and his main weapon would remain his pair of powerful bishops. It seemed also important to mention that your opponent might not feel that confident in these kind of middlegames, that he might not be so used to meeting. He might also feel that “everything is playable against such an opening”, but that would be a rather naive and dangerous way of reasoning. Recently, most of the top grandmasters have included the Reti in their repertoire.
