well im a 13yr old with a passion for chess.. i started playing and reading yasser sierawans books to understand the basics of the royal game. also i got into a opening fever and not to the point of chess which is strategy, tactics and etc, instead of the memorization of moves, without knowing the concept of why they were made.when i opened this book i fell in love with it as it lead me to victorys, defeating 2 NM's at blitz tournaments, all with the normal basics of attacking the king, which are all explained in this book. I recomend it to anyone, its defenitly a classic!. Good Luck!
