• FeelingBlue moves 4/2 4/1

Not very interesting for a bulletin board problem apparently, but it was for me with the match on the line. I was tempted to take the 'middle' road and leave 5 shots, but a good thing I didn't because, it's wrong, and also I would have got hit with opponents upcoming 54 roll. OTB, I figured that the least amount of shots would probably not be a blunder, but it's often right to volunteer a few extra shots to get closer to home with the last chequer. In this case these two themes nearly balance one another out, but statistically its right to go ugly and minimise shots.
