Above is Chase's rollout of his (original) position.
R (Run, bar/24 18/15) is a typical Nackgammon play. With multiple checkers back on both sides (and therefore less ammunition for the home boards), it is a common strategy to make the 14pt, 15pt or 16pt to help control one's own outer board and frustrate the opponent's similar aim.
Below are three variants.
[I suspect that higherply rollouts would relatively weaken H (Hit, bar/24 6/3*), though probably not enough to overturn.]
