CATALOG OF CHESS MISTAKES Andrew Soltis BOOK REVIEW

Have you ever wondered why you lose chess games? Here i s a book which t e l l s you what you've been doing wrong. In fact, i f you're anything like me, you w i l l feel like you're looking in a mirror of the past as you study the many errors which Soltis describes. Each chapter deals with a particular type of mistake, from tactical oversights to psycholog-i c a l misjudgements, and i s fu l l y illustrated with diagrams and analysis from master games. I t i s said that understanding a problem i s half of the solution to that problem, and that i s where the chess student stands to benefit from reading this book. I f one can learn to recognize the patterns of potential mistakes he should be forearmed to successfully avoid making them. - WML $10,95
