Book excerpt: This book provides one thousand combinations from chess tournament play. It is not the typical book with positions and their solutions. Rather, it tests the actual players against the computer. Sometimes the computer finds the correct solution but not always. The reader needs to study the positions and determine for himself whether the move selected by the computer is correct or not. The reader is encouraged to make notes in the spaces provided in the back and then to come back over time and review his notes to see whether or not the solution he found is correct. The objective is to sharpen the player's tactical skills by solving representative combinations that appear in typical games. The complete solutions are not provided; only the first move. This is a unique book with a method not to be found in any other chess book.
