The Modern Benoni arises after 1.d4 Nf6 2.c4 c5 3.d5 e6. It leads to unbalanced structures and exciting play, so it has naturally been a favourite of ambitious attacking players such as Tal, Fischer and, more recently, Topalov, Ivanchuk and Gashimov.The Modern Benoni is a bold answer to 1.d4 and GM Marian Petrov shows it is possible to play this line confidently without memorizing extreme levels of theory. Black must certainly be well prepared, but the workload is less than most aggressive defences this book supplies all Black needs to know."
