I do the same thing, but I want to be sure I understand something...
For the static evaluator to be blissfully unaware of checks, I have a
check extension in my qsearch as well as my search. Further, I allow the
checked side to evaluate all moves, not just captures. And as a result,
I sometimes get the runaway evaluation that John described at the start
of this thread. Isn't this approach neccessary to simplify the evaluator
as you have described, and if so, then isn't an absolute upper limit to
the search depth required?
