In this book the reader will find an opening repertoire for Black against 1. e4, based on the Petroff Defence and designed to be used up to the highest level.

This book is a completely new edition of the original The Safest Grünfeld of 2011. I rechecked all the lines and changed my recommendations according to latest developments of theory and my new understanding. Especially the anti-Grünfeld chapters are basically new. In my opinion top players have long lost hope to find advantage in the main lines and try early deviations. Anand chose 3.f3 against Gelfand and 5.Bd2 against Carlsen. So I devoted special attention to the Sämish approach with two different propositions. 3...Nc6 is less studied and probably more rewarding from a practical standpoint, while 3...d5 is in perfect theoretical shape, but requires more memorization. Every too often White players try to avoid the Grünfeld by refraining from d4 or c4. I added an additional chapter on the very topical lately Trompowsky and Barry/Jobava attack. The 7.Bc4 system in the Exchange Variation, and the Russian System have also underwent a major reconstruction.

This book presents a Black repertoire based on the Scandinavian Defence with 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd6. Kotronias offers new plans for Black in the most topical lines. They are backed by deep analysis based on solid chess understanding.

Five years after the first edition, the book was completely rewritten and redesigned. While remaining true to the original structure, this new edition underwent major changes

This book presents an opening repertoire for Black to players who are looking for initiative and counterplay in the Ruy Lopez.

By playing 1.d4 Nf6 2.c4 g6 3.f3, White kills three birds with one shot.

This book presents a Black repertoire based on the QGA. The authors consider the Classical System with 3.Nf3 Nf6 4.e3 e6, but they also offer alternative approaches – building up tension with 4…Bg4, and the destructive 4…a6 aimed at quick equalisation.
