In Response To: 42P-51S-32 XG2 RO (Dmitriy Obukhov)

I finally returned from my trip last night, so I can create diagrams again.

I'm not sure anyone else is aware of the nice contrast between 42P-51S-32 and 31P-51S-32, so I guess it's up to me to point it out.

42P-51S-32 [D d17 S27 Z29 U55] "<5

31P-51S-32 [d S12 Z25 D35] /5

You can click on the captioned links to see rollout details.

The nacbracs tell us that in the left-hand position D (Down, 13/11 13/10) is the best play, and d (down, 13/8) is weaker by .017. By contrast, in the right-hand position, d is the best play and D (fourth best) is weaker by .035. It's a margin swing of .052.
