[Retros] one man PGs

[Francois Labelle]

Hi Roberto,

I remember a discussion about the two-sided version of "one man PGs" on 
the Retros mailing list in 2004 where it was called "Lazy-Spectators-SPG".

The challenge was posted at the bottom of this post:
https://pairlist1.pair.net/pipermail/retros/2004-November/000950.html

Then Michel Caillaud listed some already published At-Home 
Lazy-Spectators SPGs in 9.0 moves and composed some in 10.5 moves:

This was followed by more attempts (often cooked) and discussion. See 
posts with the title "Two little SPG-challenges":
