It is also the case in a lot of positions in the GCP test suite and I wonder if
you think to have a different test suite in order to help you to test changes in
the search rules.

I do not know of a tactical test suite when the difficulty of the positions is
similiar to the GCP test suite but programs do not find the right move for the
wrong reason and do not change their mind fromm the right move to the wrong move
unless they have some bug.
