Actually it alone can not at all.

Reading myself I found it too hard to understand to not clarify.

By that I meant the board setting of which the eval() was propagated.

After each search we got pairs of states of approximately the same value even though the [immediate] eval() does yield different values.

I was talking about root moves, that now have a propagated value and a direct evaluation.

We know that our eval() is wrong in a particular direction.

For every move with two evaluations we know that our eval() judges it too low or to high and can try to find out why.

Because all root move result states can not be too different it should not be hard to figure out what made the difference.

They can only be different by turn, thus few (two) pieces make the difference.
