Michael: GNU 2-ply appears to misplay more than XG. Moreso after 20/14 23/21 particularly rolls 21 and 32 pointing and breaking the prime seems incorrect
7/5* 6/5 would not be my play. GNU 3- and 4-ply also play 7/5* 6/5. Perhaps someone is interested in finding out how big an error that is, and whether 8/5* or 6/5*/3 is correct. Here's the position after 20/14 23/21 and double/take.
The score is 0-0/3. White to play 2-1
