But it is! :)
6. A turn is either a pass; or a move that doesn't repeat an earlier
grid coloring.

Actually, mainly faster - there should be no strength difference if you
limit games number, not time.

You should watch my presentation. ;-) It is a technique for tree
search to try to spread parallel-descending threads to different nodes
by adding a loss to the node when the thread descends through it and
removing it when it is returning back to the root. There is some
search efficiency bonus, though the strength gain was very small
in my measurements.
