Positional Judgment
   

If you want to assess whether you will win this game or not, you make a Positional judgment. Basically, this consists of measuring territory and thickness/influence.

Measuring territory is easier in the sense that it is quantifyible, but it requires the mental pains of counting.

Measuring thickness is harder in the sense that it is not quantifyible, but one can develop some kind of intuition for it, which enables one to assess thickness faster than territory.

There is a wonderful book, written by Cho Chikun, on how to make a positional judgment, though it explains the territorial assessment in much more detail than the influence part.

RobVanZeijst in one of his [ext] columns outlines his "QARTS" system, in which he quantifies thickness and aji. QARTS is for Quantitative Analysis of Relative Territory and Strength. The idea is to assign -20 points to a weak group without eyes, and -10 points for a weakish group with room for one eye. Together with counting established territory in the usual fashion, this is a tool for judging reinforcements or the relative merits of an invasion versus a reducing move.


A search in Google turns out two revelant pages:
