In Response To: 6th move position (happyjuggler0)

This includes the rollout, 2ply evaluation, and 4ply evaluation. I didn't think to roll out 24/20 24/23 until a poster thought it was likely best based on QF (but voted for the obvious play anyway!).

Needless to say I made the automatic play. I honestly don't know what is going on here. Perhaps when white hits (11/36 of the time) on the 7pt by breaking the 5pt that he doesn't gain much equity. Combined with a much (!?) larger gain in equity from the split to white's stripped 8pt, and to white's having made an inner point already. Perhaps together they add up to enough, but seriously I am not sold.

Could someone with Snowie post a 3ply evaluation here to see if that bot is "thinking" the same way that gnu is? A rollout shouldn't seem to be warranted if they both think the same way in evaluation mode. I can't help but wonder if gnu is wrongly not hitting on the bar point or something like that.

The score (after 0 games) is: gnubg 0, blue 0 (match to 11 points)

Move number 6: blue to play 41

gnubg	149
blue	154
