What should I study at my level? From 10 low to 5 [gm levels, you should probably concentrate on recognising standard shapes as they come up in your owa games, or play through professional games looking for them. It may be hard to understand why mistakes in shape are bad play, until you have also studied the basic shape concepts. In particular the study of joscki at this point may appear to be unrewarding, plain and simple memorisation. Problem solving, first of all about basic life-and—death and then more general tactics under the heading of tesuji, is likely to seem more attractive to the player interested in progressing beyond 10 kyu. After solving enough problems from the go literature, you should begin to find the Vital points in formations. This book can serve as a reference for these standard shapes.
