Quality Chess Puzzle Book

When I decided to make a chess puzzle book I had many ideas in mind: The puzzles should be challenging but not so difficult that a chessboard is needed they can be solved on the train, plane or wherever you happen to be when you have a few minutes to spare. The positions should be educational with some instructive point to the solution. I have generally stuck to that, but I also selected many puzzles just because they were fun. The positions are all from fairly recent games, so that the reader will not have seen them before in older puzzle books.
