Seems like a great way to 'get your brain working', although I must say the game examples of the Polgar sister's in the combination's section seem to be far more advanced than the rest of the material in the book would prepare you for. Maybe it's just me, though.
Great book, if you are willing to put in the work. It amazed me how quickly I started to see patterns, how I knew how to prioritize possibilities. I'm only around a hundred pages into this tome. It is also, surprisingly fun to work with. If you are going to put in the work it's totally worth it, if not it's at least a book that might impress people if on your shelf.
