What is the reasoning behind this? If I just stop at some arbitrary place, the
in the middle of a 10 piece capture sequence, I return a totally wrong score. I
mean if there is a capture sequence of 9 ply, and you stop at 8, it might be
when white have just taken blacks queen, and you return +9, when in fact, if the
position is reached, black will just recapture whites queen.

I don't understand how this can work, unless some extra care is taken.
