Query: Giddins imitates chernevs 100 best games of chess

This book has 50 games with 50 lessons to boot. Mr Giddins annotates the games with minimal lines and a lot of verbal explanations explaining the strategies, and what the players are trying to do in the game. It follows chernevs 100 best games of chess, and contains more modern games. Since Mr. Giddins is an expert on unknown russian chess games, there are a lot of those annotated in the book as well. I preferred chernev's 100 games over this book as it had a lot nicer games and in larger quantity, but this book contains some hard to find russian games that I found nice. It is good for the improving player to go over these games as well as other books, such as Rubinsteins 100 chess games by kmoch and Capablanca's games by Reinfeld.
