This book considers a gambit treatment of the Slav and the Semi-Slav. White offers the c4-pawn in order to get a space advantage and a long-term initiative. It also covers the Closed Catalan and the modern line 1.d4 d5 2.c4 e6 3Nc3 Nf6 4.Nf3 Be7 5.g3 0-0 6.Bg2 dxc4 7.Ne5. The author's idea is to throw 1...d5 players off their comfort zone by dragging them into sharp unbalanced positions. If you're fed up with the all mainstream Slav/Meran theory out there, this book will offer you new refreshing approaches for both sides.
