Manual Step 6 of world's leading teaching method in chess. For independent students rated up to 2100. This step by step method consists of six steps. Each step has a workbook with exercises and summaries for the student and an accompanying manual for the teacher / trainer / parent. The manuals contain complete scripted lessons for the teacher, as well as aids that address the learning stages and development of children. Because there are so few chess teachers capable of teaching Step 6, this manual has been written as self-study book. See also 'Learning Chess - Workbook Step 6'.
I didn't read this or the Step 5, book that carefully; I achieved 2300 or so FIDE, without studying either of them or Step 4, at least against a computer. They warrant re-reading, with a bit of care. (using the workbooks of course) The basic training through Step 3, improved my play markedly (from 1700-2300). Well worth the time. Recommended.
