EXPERIMENT 28:

In this experiment, GnuBG 3-ply checker skill, (strong bot), played 20,000
money games against GnuBG 1-ply checker skill (weak bot).

Strong bot won 13,100 (50.82%) and weak bot won 12,679 (49.18%) of
the points, with a total of 25,779 points and an average of 1.2890 points
per game; strong bot won 10,137 (50.69%) and weak bot won 9,863
(49.32%) of games.

In comparison, in the cubeful version of this experiment, strong bot won
24,247 (51.43%) and weak bot won 22,901 (48.57%) of all points, with a
total of 47,148 points and an average of 2.3574 points per game; strong
bot won 10,215 (51.08%) and weak bot won 9,785 (48.93%) of games.

As weak bot won 0.61% less points and 0.39% fewer games, this time we
can see that the weak bot performed worse, even if by a very little, in the
cubeful session than in the cubeless session, as some may have expected.

I will add some conclusion drawing comments here after doing more
experiments along the same lines.
