What's this for? It causes weird things to happen with short lists.

Unless I've totally misunderstood your spec, you don't need all that
islice and stoplist stuff.
def chopupmoves2(movelist):
parlen = len(movelist) // 3
return [movelist[:parlen], movelist[parlen:parlen*2],
movelist[parlen*2:]]
for k in range(13):
mlist = range(k)
print
print "v1", chopupmoves(mlist)
print "v2", chopupmoves2(mlist)
