In Response To: The 3 is easy (neilkaz)

OTB I couldn't see the differences Peter pointed out and figured it was very close. I analysed this match in XGR and it picked up my error. I didn't believe it was non trivial so I rolled it out 3888 and the rollout agreed so I extended the XG rollout and decided to check GNU as well. Will post XG from home.

The score (after 0 games) is: gnubg 0, user 0 (match to 3 points)

Move number 6: user to play 23

gnubg	52
