Adrian Storisteanu: See also slight variation P0577817. (2015-09-12)
Gunter Jordan: Dies ist kein Umwandlungswechsel, dazu müssten die UW auf dem selben Feld erfolgen. (2023-01-11)
A.Buchanan: Why would we talk of helpmate promotions (particularly black ones) as underpromotions. Is a knight ever an under-promotion? And we still with all this under-promotion effort don’t know what the pieces are: it might be rook or bishop. Just label them as promotion:lts and be done (2023-01-12)

A.Buchanan: For h# problems, Art. 15 is just a motivation for set play. They come down to the same thing, pruning the first single move. So if we talk about set play for an Art. 15 problem, maybe it means *after* the player has been flipped for retro reasons. And set play doesn't care whether the position is legal or not! (Otherwise it would be called "*consequent* set play", maybe!)
So here we start with a h#3*, which for retro reasons, becomes a h#2.5*. This yields a mate in 2.5 and a mate in 2.0, and comically we never get to worry that the latter is in an illegal position. If there was a clean mate in 3.0, that could be denoted h#3v, to indicate the try.
Does that work as a notation? How about directmates? (2021-10-20)
Henrik Juel: In problems with stipulations like #2 or #3, the convention is that the number (2 or 3) is the number of white moves, so there the retro joke is clear
For helpmates there is no such convention, but your notation seems OK (2021-10-20)
