Henrik Juel: Missing Joke keyword, I guess (2020-05-11)
A.Buchanan: Curious that retro a7-a8=sT discomforts the animation still - maybe you should report to Gerd? (I trouble him with enough stuff already - don't want to be the only one emailing him! :-) (2020-05-11)
A.Buchanan: Maybe +sBe7f7 to refute R. ... e8=sK/fxe8=sK :-) Note this "cook" is actually prevented in the original. (2020-05-11)
A.Buchanan: Oops and a more major cook R: 1. Se8/g8-f6+ (2020-05-11)
James Malcom: This problem was only half-finished before I fell asleep. It’s fixed now. (2020-05-11)
A.Buchanan: Great! You could save another piece I think -sLg6, -sBf7, + sDf7. This also removes the obtrusive promotion (2020-05-11)
James Malcom: Yes, that is true. Position edited. (2020-05-11)
James Malcom: I see nothing wrong with fiddling if it improves economy. (2020-05-11)
A.Buchanan: If promotion to Bl unit is allowed, can’t Bl just have played e8xd7+ or g8xh7+? Can replace bPd7 with bR but eliminating bPh7 is more complicated. Need +wPh7 +bPg6h6. And also bRb7 to prevent discovered check by bPc8 prior to e7-e8=bK. I think that’s watertight now! :-) (2020-10-13)
A.Buchanan: The issue is that there are two or three levels of Bl promotion joke: this problem relies on the "basic" joke where black officers can be created. But where's the line to stop us promoting to Bl pawn or king? If we go that far, then a position like this 2kr3K/1r1r1qrR/7p/8/8/8/8/8 is required. Oh dear: sorry to have brought it up :( (2020-10-13)

Within hours, the English problemist Michael McDowell sent me a Belén problem that was both a Meredith and a three-mover.

(diagram)

"Or start Na4 on c3 for a 9-piece setting if you don't mind a flight-taking key," he added. Man for man, that setting was later independently also sent to me by Joshua Green. (The key is then 1.Na4)." [P1380105]

A.Buchanan: The castling & e.p. conventions are not inherently retro, although they may combine with other content. We don't enough about the history of the game, so the convention simply decides (2020-09-21)
James Malcom: Wrong problem to comment on, Andrew? (2020-09-21)
A.Buchanan: Hi James - I should have said: this problem was marked Retro not #3, so I changed the genre. My earlier comment is an explanation (2020-09-22)

Very nice, James and Andrew (2020-09-29)
A.Buchanan: Thanks Henrik - Belen precondition of bKc1 was satisfied 1.0 move ago. From that position there is a sound #5 but position is clunky and not Meredith.
You didn’t fall into the trap of thinking Black has no last move: there is a dualized solution with BTM waiting for you if you did. (2020-09-30)
James Malcom: Haha, yeah. I fell for Andrew's trap, hook, line, and sinker! :-) (2020-09-30)

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)

Definition:
Three trys by different white pions fail on three different escapes of the black king from the corner.
In the solution, two completely different matt images: one on the edge, which ends with pattern matt, and one surprisingly in the middle of the board.
Kindergarten problem.
Rex-solus.
Miniature.
A.Buchanan: Two of the tries are bogus in that the sK move is forced. It’s like counting a random queen check as a try if Black’s only legal reply is to capture the queen (2020-11-06)
