65R.32S.53.65? - Rollout

While I've been busy the past week I've tried to keep up with at least reading and tossing on some rollouts. Now that I have time, I'm going to repost the results, not in the original threads, because thankfully all of you have kept the forums busy and most of the posts have been kicked way down.

Here, I felt 21/10 was clear. By moving the front checker you create another builder at the cost of a few more indirects while you're down in the race. The few more indirects are devalued even further since if you leave it, it's subject to attack being the lone checker back, no possibility to anchor, in a close race.
