You may recall that in the recent problem, "Which point to make?"
XG thought that allowing 4 hitting rolls was too much risk. So
here, you might think that something like 11/5 10/8 is indicated.
However, XG thinks that 11/5 10/8 is a whopper, and wants to fill
in the gap with 7/3(2). But see the variant.
