New Chessable imprint! This book is based on what was voted the best opening course on Chessable by its users. German coach and YouTube personality IM Christof Sielecki, aka Chessexplained, presents a complete solution to chess players of all levels for their opening choices with the Black pieces. With this repertoire, the reader will not only safely navigate the opening phase, but will also understand what is happening and how to play for a win. Why is the repertoire called simple? For the simple reason that the variations are straightforward, easy to remember, and require little or no maintenance. But, as IM Sielecki puts it, simple does not mean boring!
