Chess Puzzle Books
600 Positions to Improve Your Calculation and Judgment
Many puzzle books take a far too simplistic approach and offer endless positions where the solution is nearly always along the lines of: queen takes something check, king takes queen, check, check and a pretty mate. Aesthetically pleasing perhaps but of minimal use for actual improvement as the patterns are so familiar. Practical Chess Puzzles avoids this pitfall. The positions chosen are far more like those that actually appear on the board during the vast majority of games.
