So, if you care about comp vs comp results, you add a little option that makes
your program try to create closed positions against computers. You lose about 60
rating points on SSDF for the slow down. At the same time gain about 300 points
on SSDF because Fritz and most of the others self destruct every time you
succeed in making a closed position. So you finish ahead.

And you stop losing to the anti-computer experts on ICC as well.
