This book presents the Triangle set-up, which arises after 1.d4 d5 2.c4 e6 3.Nc3/Nf3 c6. This move order avoids many unpleasant systems for White, notably the Catalan, the Exchange Slav and the Botvinnik Variation. It leads to sharp strategically unbalanced play and brings Black excellent practical results.
