Not at all - uneven scaling would be a nonlinear transform and this 
isn't possible in a raytracer.  See

http://tag.povray.org/povQandT/languageQandT.html#bending

for details.

I seriously doubt Go pieces are in fact continuously unevenly scaled 
spheres - if they were it would be quite difficult to create the forms 
to manufacture them.  More likely they are composed from a differently 
scaled upper and lower half - you can do this with CSG in POV-Ray.
