Above is a rollout of a position very similar to Stick's (51S-52S-21@-21E-41 by Mike's sequence). The difference is that I moved one of Blue's 6pt spares back to his midpoint. Even with this change in checker distribution, note that & (double slot) is very close to T (Tower).

What happens if we change the roll to 64? Inspect the rollout below.
