This test position is bad.
Programs can easily solve it if they want a draw and believe that black is
better when white does not play Ba3.
I want to use a test suite when programs cannot see the right move for the wrong
reasons for future tests.
I remember that I read that the quick test suite is a good test suite for this
target but I do not remember where to find it.
