The best way to improve at chess is to solve tactics puzzles. But why do regular tactics books make amateurs study master games? Is it useful for beginners to analyze games that are unreal for everyday chess players?
In the real world of beginning and casual players openings are dubious, positions are messy, material is uneven, and cheap traps and oversights are occurring almost constantly. Most amateur games are won by rather primitive means, compared to the cool and fancy moves that masters need in order to gain victory.
This book only takes positions from genuine amateur games and puts them out there, warts and all. Tim Brennan and Anthea Carson have assembled thousands of games by everyday players, and selected the most instructive tactical examples.
If you want to improve at chess but have limited time and energy available, this is your book! Now you can study positions that are happening in games you yourself might have played!
