Well, if white do not try to win and want to force the draw it is draw, but we
were playing white and want to win.
This line is not good to win as black has at least a draw.
For me this is specific preparation (preparation against Shredder) which is
allowed of course.
I believe the program was showing a good evaluation, but that only confirms my
statement that the program did not realize black was a little better.
