I want to attack here, so I'd start with 3/1*. Then we could go
all out by switching points with 4/2*(2), but I don't think we have
enough ammunition in the zone for that. I'd bring down two more
checkers with 13/11(2). For the last 2, 23/21 gets ready to launch,
whereas the other 2's don't seem to accomplish much, so I'd try 23/21.

XG goes full bore with 2 infield hits and leave the blot on 23 in place and brings down more ammo from the midpoint. I felt some urgency to getting that blot on 23 out of there.

That's interesting that XG thinks there's enough ammo in the zone to
support the all-out blitzing play. Below is a variant that I found
interesting.
