Thank you for your brilliant analysis!

With regard to your challenging variation 51S-44B-41U-44, P (Point, 9/1*(2)) does not appear compelling to me because, here, the game plan blitz will probably become a flash in the pan without the vulnerability of White´s home (blot on her 4pt). Instead of P, my ideas range from C (Cross, 24/16(2) 9/5(2)) to A (Attack, 9/5(2) 6/2(2) and O (Outer, 13/9 9/5(3)).

O (Outer, 13/9 9/5(3)) brings one extra checker into the zone, and exerts pressure on the backchecker on the acepoint, but it strips the midpoint.
A (Attack, 9/5(2) 6/2(2) unstacks the 6pt, and it develops Blue´s home. Yet it omits some action on the far side of the board which I would prefer.
For this reason, C (Cross, 24/16(2) 9/5(2)) appears more well-balanced. It makes the golden point and moves up the anchor.

C or A? I tend to C. 24/16(2) 9/5(2)
