Negative levels are not really supported. However there is some
improvement in strength past level 10. Processors are faster
now and sometimes GNU Go has been run at level 12 in tournaments.
I think there are cases at around level 18 when GNU Go did not
seem to terminate and make a move in a reasonable amount of
time.
