Predator at the Chessboard - Ward Farnsworth - Bog

Chess tactics explained in English: the second volume of material from www.chesstactics.org. This book is the second in a two-part set. The two books together contain over a thousand examples organized in unprecedented detail. Every position is accompanied by a commentary describing a train of thought that leads to the solution; these books thus are the ideal learning tool for those who prefer explanations in words to long strings of notation.
Book II -- the present volume -- covers pins and skewers, removal of the guard, and mating patterns. (The first book in the set provides an introduction to tactics and explains forks and discovered attacks.) Also available in hardcover.
