"A great book of simple mates in 1,2 and 3 moves with combinations and games as well. This book will give you firm visual pattern recognition practice, a necessary building block for tactical combinative play. You would not build a house without bricks - these are the bricks."
"Pachman's classic book that is extremely readable and contains a huge amount of useful examples and explanations on CLassic to pseudo-modern chess strategy. A transitory book to be read between "My System" and "Secrets of Modern Chess Strategy"."
"A more challenging problem book on true combinative play. Problems get more and more difficult as you progress through the book, truly giving the reader a challenge. Use in conjuction with the Polgar book."
