Next to strategic planning and tactical analyses, positional judgement belongs to the basic and most important abilities of Go. Positional judgement includes the correct evaluation of territory, influence an potential and answers the most important questions: who leads and how high, where on the board is still hidden potential and what strategy is in regard to the status of the game reasonable. This is the fundament for all deep tactical and strategical decision making. Mostly the accurate counted territory is - subject of this first volume - the most important issue of positional judgement. In the second volume the dynamic aspects of positional judgement are central, like influence, reduction, aji, potential, thickness and fight. These concepts are explained with several examples and 100 middle game problems.
