In Response To: Find an ace - Rollout (Stick)

I didn't think the upcoming the plays were tricky enough to disqualify 0-ply, and I wanted a quick result. My rollout settings were to stop at 2.5 jsd with a min of 324 games, and that did the job. I'm sure Chuck won't be sending the rollout police to give me a kicking.

Here's a related position that also shows the superiority of 8/7. This is something I obviously need to get my head round.

The score (after 0 games) is: White 0, Joe 0

Move number 5: Joe to play 31

White	130
Joe	164
Position ID: w2aHAyBmZmGARQ Match ID: cIkFAAAAAAAA

Rollout 1296 trials at 0 ply.

Annotation

Filling in the five point makes 8/7 too risky, acording to 2-ply, but the rollout again favours the open play.
