I played 8/6 4/3*.
Unfortunately, XG doesn't set QF problems.
I haven't done a rollout though.
Maybe it wasn't the worst checker play in history.

There is a fairly short list of reasons for a banana split.
You might need a tempo desperately (but that's not the case
here---O has no big attacking or priming threat, nor does she have
blots to pick up). It might be the only way to prevent O from
running the last checker and locking up the game (again, not
the case here because O is far behind in the race, and running
her back checker hardly wins the game for her).

Trying to keep a blitz going is not usually enough to justify
a banana split.
