Now I am tempted to purchase his book over amazon.com
I think "How Chess Games are Won and Lost" is his best. It has many of his games as examples, and he loses several of them, so I felt that I was learning with him, not just from him. It is rare for a strong GM to teach from his losses as well as his wins.
His "Secrets of Chess Endgame Strategy" is also excellent.
"Foundations of Chess Strategy" is my favorite, though, because it made me re-evaluate myself as a player. It also helped me appreciate that there is more than one way to approach the game. He is methodical and theoretical, but at the same time very "un-dogmatic" about the game.
