This Grandmaster Repertoire 20 - The Semi-Slav by Lars Schandorff is an English-language chess opening book that presents the Semi-Slav Defence as a Black repertoire against 1.d4. Part of the Grandmaster Repertoire series, it offers serious opening preparation in a clear, well-organised format.
This is a book for players who want to understand the Semi-Slav properly rather than simply memorising lines. It is suited to opening preparation, tournament study and repertoire building, and it gives readers a practical way to work through one of the most important defences against 1.d4.
What this book covers
Lars Schandorff builds a complete repertoire from Black’s side and focuses on the key ideas, typical pawn structures and critical moves that shape the opening. The result is a title that can support both day-to-day study and more focused tournament preparation.
If you are looking for an English book on the Semi-Slav Defence, this volume from the Grandmaster Repertoire series is a straightforward addition to a serious chess library.
Reviews and praise
GM Simen Agdestein wrote of Schandorff’s earlier 1.d4 books: “I have recently been reading Lars Schandorff’s Playing 1.d4 books, thinking that it cannot possibly get more instructive than this.”
GM Boris Avrukh summed them up briefly: “Lars, I want to play your book.”
IM John Donaldson said that Lars Schandorff has a gift for creating opening books that are both accessible and practical to use, and described this title as essential reading for anyone who plays the Semi-Slav Defence.
