In Response To: 52S-64R At Gammon Save will be posted soon (David Rockwell)

I'm sure David is doing a XG rollout and we'll see if what he ends up with is any more definitive than what we had already with GNU. This is one of those early game plays where if you're significantly stronger than your opponent not hitting is a big error in my opinion. Note, running loses more gammons.

The score (after 0 games) is: gnubg 1, user 2 (match to 3 points, Crawford game)

Move number 2: user to play 46

gnubg	160
user	167
Position ID: 4PPgASTgc/ABMA Match ID: 8Al6ABAAEAAA
