I think that the main problem is that humans do not know much about chess and
the positional test suites are not good because of this reason(they often have
not the right moves as solutions).

The tactical test suites are also not good because most of them involve
sacrifices and there are cases in games when there is a tactical idea with no
sacrifice.
