15552-game rollout of 41Z-65R-43

A week or two ago I posted the position after 41Z-65R-43 and expressed my surprise that GNU thought the defensive 5-point was better than the offensive 5-point. Neil asked for a longer rollout; see below. My play of 9/5 8/5 appears to be slightly preferred, but really it's still TCTC. I don't plan to roll this out any further.
