Pachi is currently completely unoptimized here; I had an optimized
version at one point (not sure if I ever committed it), but then had
to deal with too many bugs so I better removed it again. What I have
in mind doing is first separating local gammas with contiguity (that
could should take a lot of the cases) and using the row sums trick
for non-local gammas.
