I agree with your assesement, but whenever I tried checks in
qsearch, my search blew up. Even if I limited them in all kinds
of ways, the branching factor got out of hand. It already is
somewhat large, so I couldn't allow it to get bigger.

I wonder if you 'try' checks (have a few rules that indicate
when it might be worth trying certain moves) or 'filter' checks
(have rules when a check is prolly bad) or do something
even different.

Because I couldn't get it to work in qsearch, I've been trying
to make the evaluation catch those blind spots. So far, it helps
againt the biggest problems, but still...
