In a blitz, one should generally focus on attack first and defense
second. But here, X has four checkers behind O's five-prime, and
urgently needs to escape before collapsing. So 24/21 is a must,
and then the question is whether leaving the 5pt slotted (hoping to
make it) is worth the risk of getting it sent back. Again, under
"normal" blitz conditions, the gain of making the 5pt might be
worth the risk of leaving a direct shot, but here, XG says it's a
whopper with cheese to play 24/21 13/11.

If X didn't have so many checkers boxed in behind O's prime then
the decision would be a lot more complicated (see variant).
