Me vs. Falafel 53 Holding Game ROs

From this thread:http://www.bgonline.org/forums/webbbs_config.pl?read=53597.

I played 16/8, not burying since the race was close and I am approaching a cube. GNU preferred my play by about .045 on 2-ply. Falafel bet that 11/3 was right. After about 2k trials his play was slightly ahead on my GNU RO but nowhere near statsig; my play was slightly ahead on his Snowie RO, we called it a wash.

I started doing some Snowie ROs on my other computer which then broke for unrelated reasons but I lost the Snowie ROs. I would have liked to see those but just didn't work out. XG RO was posted in the thread.

To make sure there were no peculiarities with whatever the bot was doing I did ROs with a centered cube and a turned cube. Not much difference, though, as 11/8 6/1 wins both on GNU. Not sure that I entirely understand why this is better than 16/11 6/3 or 11/3.

The score (after 4 games) is: atrifix 4, fanar 4 (match to 7 points)

Move number 20: atrifix to play 53
