This book offers an entertaining way to test your skills and train yourself with 300 positions taken from actual games.

I loved this book because you don't need to have a chessboard at hand, you just try to solve the problems looking at the position diagram on the book. This alone is a good training for your brain, helping to develop the capacity to think ahead and visualize combinations in your head, after all when one is in an actual game you have to be able to analyze positions and visualize moves and combinations.

I truly believe anyone can benefit from exercising his analytical and visualization abilities.
