[computer-go] Odd results on 19x19

[David Fotland]

The styles of CS (CS-9-17-10k-1CPU), MFGO (mfgo12exp-15), and GNUGO
(gnugo3.7.10_10) are different, and it's generating some odd results.

Many Faces beats GnuGo 70%.  There are not many games, but this is
consistent with over 100 test games I've run.
CS beats GnuGo 55%.  Over 100 games played.
CS beats Many Faces 90%.  Only 20 games, but consistent with earlier
results.

If we look at results against GnuGo, Many Faces seems stronger than CS, but
in games against CS, Many Faces is much weaker.

Many Faces plays a fighting style, and CS plays a territorial style, but I'm
still surprised at the difference.
