This rich book on chess tactics proposes a revolutionary method for finding winning moves. Charles Hertan has made an astonishing discovery: the failure to consider key moves is often due to human bias. Your brain tends to disregard many winning moves because they are counter-intuitive or look unnatural.
The Small Encyclopaedia of Chess Openings is based on the same 500 fundamental codes and system of elimination but it's a fifth the length. Instead of five books just one! The best and most up to date information. The creative output of generations of chess masters filtered for the reader's convenience.
