People do not use the word positional for material. positional evaluation is the part of the evaluation function that is not about counting material. When somebody wins material in game it is called tactics. Positional understanding is about the value of the not material factors. Positional understanding is important in chess because there are position when one side has less material but better position. If you search deep enough you can see that the side with material advantage is losing but there are cases when you need to see 50 plies forward to see that the side with material advantage is losing and computers cannot see it by search. A good program must have positional evaluation that tells it in part of the cases even without search that the side with material advantage is probably losing. > > >>"perfect" or "final truth" or "general orientation."

The problem is that people do not understand you and it is usually not the case with other people. You can explain yourself better even without knowing standard definition by giving definitions for what do you mean by the words that you use. Uri
