general assessment can also be wrong.
general assessment is result of experience and it is possible that the
experience is misleading because the position that you look at is slightly
different than the positions that your experience is based on them and the
difference may mean that instead of having bad position you have better
position.

I think that you need concrete lines also when you talk about positional
evaluation.

Of course in case of positional evaluation you cannot have a forced line but you
can have some logical lines that demonstrates that white get the advantage.
