In Response To: Prime vs. Prime - Blue to play 4-2 (Carlo Melzi)

Over the board I played 9/3, follow-up was:

6-2 Bar/23 13/7 6-4 9/3 8/4

end I eventually lost the game.

From my rollout, it seems that the big downside of the dumping move is the high number of gammon lost.

However, it seems like at this score 6/2* 3/1 is actually best, as it wins about the same number of games and a few more gammons.

Do you think we can trust this rollout?
