The first two rolls started to steer the game towards mutual priming. So, it's best to improve on both sides of the board by splitting the rear checkers.

Splitting is even more urgent if white has a stronger priming structure arising after 43D-31P-21:

However, in 43D-64P-21 (the second roll is misplayed) white has an attacking structure, so splitting is not the best idea. (Rollout due to David Rockwell.)
