If you haven't yet, you might enjoy reading "Bobby Fischer Goes to War: How A Lone American Star Defeated the Soviet Chess Machine" by David Edmonds and John Eidinow.
Great book about the 72 match. The book isn't focused on chess, as much as it is on the battle and struggle of the key players of the match.
I watched the match on tv as a little kid. Everyone started playing then, it seems, even me.
I've played competitively. Great fun.
If ever looking for a book about chess itself, I like "My 60 memorable games, by Robert Fischer". Recent versions are algebraic notation, which I prefer. I think for many levels of players this is a good book, because Fischer really does a great job in his move by move analysis. Honestly better than any other author in taking the reader through high level moves. Not a "how to play" book, but rather a fabulous "why I made these moves" book. Play the moves on your board while reading it, and I bet you will gain insights. The kind of book I can say that about with any level of player, as long as you know how to follow moves from notation.
