Every chess fan marvels at the wonderful combinations with which famous masters win games. How do they find those fantastic moves? Do they have a special vision? And why do computers outwit us tactically? 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. We can no longer deny it, computers outdo us humans when it comes to tactical vision and brute force calculation. So why not learn from them? Charles Hertan's radically different approach is: use computer eyes and always look for the most forcing move first. By studying forcing sequences according to Hertan's method you will develop analytical precision, improve your tactical vision, overcome human bias and staleness, enjoy the calculation of difficult positions. This New and Extended Fourth Edition presents 50 pages with new and instructive combinations. With a foreword by three-time US chess champion Joel Benjamin.
