I have not had the fortune of reading the other four books in Seirawan's series, but this book makes me want to try and get a hold of them.
Seirawan covers twelve modern grandmaster games in move by move explanations. There are not enough chess books on the market that do this, I feel that this sort of book acts like a bridge for the intermediate player to walk over into the advanced realm. Even beginners (with a basic positional and tactical understanding) will learn and enjoy the games that Seirawan has annotated.
Seirawan writes with originality, and provokes the reader to think for himself as he reproduces annotations by other world class grandmasters and then argues with them. This is something not seen in enough books of chess.
I am not giving this book five stars for one reason. Microsoft Press decided that they would publish this book as an incomplete version, they left out six games (the original would have eighteen, the one published only has twelve).
For players who want similar move-by-move accounts of chess games, take a look at 'Kasparov vs. Deep Blue: The historic match between man and maching' by Bruce Pandolfini, and 'Logical Chess: Move by Move' by Irving Chernev.
