John's rollout of 43Z63H41 is shown above.
By moving one of Brown's 10pt spares to his 10pt, we get 43Z32H41, where a different best play emerges (see the first rollout below).
Instead, if it is Brown's 8pt spare that is moved to his 10pt, we get 43Z43H41, and the result is a tie (see the second rollout below).
