Chess books written by Aagaard, Dvoretsky and Kasparov are suitable books for master level players. I have recently discovered the book *Perfect Your Chess* by Volokitin & Grabinsky which is similar in vein. What other chess books are suitable for master level players?

I use the term *master level players* to refer to players who are at a level equivalent to 2200+ FIDE rating. Books suggested should:

 - be suitable for a general master level player.
 - contain sufficient material that will stimulate a master level player.
 - be useful in the training of a master level player.
