GNU Go is tuned to play best at level 10. At higher levels, it
is not certain that it will play any better, only slower. Two
years ago, around the time of the 3.0 release, we did some
testing and found no improvement at levels above 10. Of course
the program has changed since then, but I recommend using level 10.

One thing that may make it stronger is to compile it with
experimental semeai. That is, 

'configure --enable-experimental-semeai; make'

may make an engine that plays better during complicated
fighting, though it will also make the engine slower.
