X to play 55

It's tempting to try to blitz here, but after 15/5*, what are the
other two 5's? 8/3(2) breaks the 8pt and leaves a ton of return
shots, while 13/8(2) and 6/1(2) are both rather awkward. XG prefers
13/3(2), which keeps the return shots down and is more likely to
hold on to X's lead in the pip count.

In the variant below, I have moved a spare from X's midpoint to
his 8pt. XG favors 15/5* 8/3(2), which no longer breaks the 8pt.
