Chess books for Young Players

The magic formula to improve your game consists of two components: study and play. Study provides the theory and play provides the practice. Together they formulate the most effective way to improve your game.
Finding a good chess teacher in your area should be your first step. There is nothing better than having an experienced teacher to guide you and provide you with a well rounded study plan. Many teachers will also take you to and coach you at local and national tournaments.
Pattern recognition is the key to learning tactics. Study the tactical patterns in the problems given in the suggested books above. Try and work out each problem by spending no more than a few minutes on it. Then if you still haven't figured it out look up the solution in the book. Mark the ones you missed. Then move on to the next problem in the book. After you have completed the book, go back a second time over the problems you missed. This is the most efficient way to learn tactics!
