Yes, I see.

My problem was that for SEE, my king value could be as large as I wanted (within
an int), but for storing evaluation scores, I want the material values to be
small, as they have to fit in a hash entry. But of course, that doesn't matter
as for evaluation purposes the values of the kings are balanced out.
