Book excerpt: Renowned chess teacher and grandmaster Artur Yusupov continues his complete course of chess improvement. Volume 1, The Fundamentals, showed club chess players the basic ideas they should know. Now Volume 2, Beyond the Basics, sets off on the road to mastery. Yusupov guides the reader towards a higher level of chess understanding using carefully selected positions and advice. This new understanding is then tested by a series of puzzles. Artur Yusupov was ranked No. 3 in the world from 1986 to 1992, just behind the legendary World Champions Karpov and Kasparov. He has won everything there is to win in chess except for the World Championship. In recent years he has mainly worked as a chess trainer with players ranging from current World Champion Anand to local amateurs in Germany, where he resides.
