Last two moves?
(-:
See P1234039 and P1375777
The joke here is that pawns may promote to enemy officers (but not to pawns or kings)
Henrik Juel: R: 1... 0-0-0+ 2.a7-a8=sT! (2020-10-12)
A.Buchanan: Maybe this is a moderate joke where we allow promotion to Bl officers, while son-of-P1375777 can be the extreme joke where promotion to any Bl unit is allowed (i.e. pawn & king too), including in the history of the game. What would Josef Cumpe think? :-) He and I are both dressed as clerics in out chesscomposers' blogspot pics: http://chesscomposers.blogspot.com/2012/08/august-16th.html. Perhaps he was a real one though? (2020-10-13)

Last two moves?
(-:
See P1234039, P1375777 and P1380852.
The joke here is that pawns may promote to *any* unit (friend or enemy; officer, king or pawns).
Henrik Juel: R: 1... 0-0-0+ 2.a7-a8=sT
not 2.e7-e8=sK, because then sTa8 would have moved, and castling not allowed (2020-10-14)
A.Buchanan: Exactly, Henrik. Also: sB on 7th rank could retract to 8th rank, so we need sT instead (2020-10-14)

Henrik Juel: Three ep captures in the retroplay was first shown 105 years ago, P0002031 (2020-11-06)
James Malcom: Many, many thanks for that Henrik! However, this seems to be the first bicolor 3 ep representation?!

Also, how many other 3 ep retractor showings are there? I have only found a few: P0000018 (cooked), P1193561, and P1193562 come with a hoard of promoted pieces, and P0000326, P0002591, and P0002031 are all "proper" retractors, but all of them are one-sided. (2020-11-06)
Henrik Juel: James, you might want to try to find the first example of 4 ep captures in the retroplay
The best chance is probably bicolor (2020-11-06)
Henrik Juel: In the proof game genre, which is easier than the last moves? one, the current PDB records are
Orthodox: 3 ep captures, P1000929
Madrasi: 8, P0005964
Circe Parrain: 10, P1095546 (2020-11-06)
James Malcom: Henrik, the fairy record actually is- Anti Take & Make: 13. P1380673
I know of the solution thanks to Juraj, the fairy master, on Matplus.
Also- Monochrome: 3, P1240593

And indeed, 4 is likely is more possible with bicolor, as 4 by one side can only be done with at least one promoted piece Q/B, which may very well be frowned upon no doubt.

And also on an interesting note, in fairy retractors, it seems that 5 has been done at the least in a VRZ, Typ Proca, P0003873. (2020-11-06)
James Malcom: Actually, it turns out that the bicolor representation has been done before, no shocker there: 1969, P0004900 & 1994, P0004497 I've tagged all of these showing under "ep in retroplay' for better clarity and searching. (2020-11-07)
