In general, staying back generates more opportunities to get and
hit a shot, but the straggler is more vulnerable to getting attacked.
Here, O's board is almost as strong as X's, and the risk of getting
attacked forces X to run the straggler. But see the variant below,
where staying back still leads to more gammon losses, but XG thinks
it wins enough extra games to compensate.
