A.Buchanan: How about wLa1 instead? (2020-10-06)
Henrik Juel: Yes, that would improve the economy slightly (2020-10-06)
Ladislav Packa: wBa1 is illegal... (2020-10-07)
A.Buchanan: Hi Ladislav why is wLa1 illegal, please? That was essentially my question before (2020-10-07)
Mario Richter: wLa1 instead of wDa1 is of course legal too: one of the dark-squared wBishops unpromotes on h8, one wQueen on g8. Black pawns g7+h7 let the wPawns g2+h2 pass by cross-capturing the 2 original wRooks. (2020-10-07)

Add the black queen
b) +wSb1
Marken Foo: There is a twin (b) +wSb1 pointed out by the chess.com user caveatcanis back in 2016, when accidentally misreading the diagram. It turns out to be a cute twin that fits the idea. (2020-10-21)
A.Buchanan: How many of these "Where in the world is Carmen Sandiego?" problems have you got, Marken? is it worth making a keyword? https://en.wikipedia.org/wiki/Carmen_Sandiego (2020-10-21)
