A.Buchanan: There is a good try here. It seems that there are two possible pawn histories. In the one in the given solution, wBef cross-capture, while wBah are waylaid (= captured by officers on their own original files). In the other, sBef cross-capture, while wBah capture to promote. In the latter case, could sS or sT uncapture a white officer which, following various parity-fixing adventures, unpromotes on b8, and then gives White the necessary tempi? The Black cross-capture would have been wBe2-6 sBf7-f6xe5 wBf2-f7 sBe7xf6-f5. I could imagine a situation with sSd8, sTc8, wDb7. Then R: 1. Db8-b7 a7-a6 2. b7-b8=D Tb8-c8 3. a6xSb7 Sc5-b7 4. Kg8-f8 Sd3-c5 5. Kf8-g8 Sf4-d3 6. Kg8-f8 Sg6-Sf4 7. a5-a6 Sf8-g6 8. a4-a5 Te8-e7 retropat. In this line, wPh3 was not waylaid, so can't get that extra critical tempo. a3-a4 is not possible because then wTa1 could never have escaped its home. (2022-01-24)

paul: The first 7 moves tested by WinChloe in 2 hours. (2019-12-15)
Henrik Juel: Jacobi 0.7.5 in Heuristic and PG demolition mode did not find the intended solution using more than 10 hours
The best attempt was 1.a4 e6 2.a5 La3 3.bxa3-f8=L Sc6 4.Ld6 cxd6-e7 5.a6 Dc7 6.axb7-b5 La6 7.bxa6-b7 Sf6 8.bxa8-d8=S Kxd8-b7 9.h3 Kc8 10.h4 Kd8 11.h5
Note the natural notation of the Take&Make moves, far better than something like 3.bxa6[-wBa6,+wSa8], which should be written as 3.bxa6-a8=S (2021-10-23)
A.Buchanan: I will copy Gerd Wilts on your notation suggestion, which doesn't work quite now here but might be made to work - I agree it's superior. (2021-10-24)
Nightrider: What a pleasure to read this! I invented take&make, and I used the natural notation (like "bxa8-d8S") right from the beginning. Isn't it ideal if readers may understand the idea of a condition immediately by the notation of the moves?

By the way, the same holds for the (much more recent) condition make&take, where a move of a wSc3 that captures a bBg8 (for example) should be written analogously as S-f6xg8. Here again, does this natural notation not make clear on the spot what the basic idea of make&take is?

(And does it not look MUCH more elegant, for both conditions, if they are written in small letters exclusively and without blanks around "&" ? For me, it was always take&make and (years later) make&take. But, de gustibus non est disputandum...) (2021-10-24)
A.Buchanan: Hi Nightrider, thanks for kind words. I did email Gerd directly after the earlier post. He's pretty busy at the moment but in a few months thinks will have more time to deal with some items on the backlog.
For names, I agree that syntax varies. Sometimes it's down to taste, more often it's just random noise. There's also the question of "&" versus "and". (StrateGems uses both in one page!) In German, nouns are always capitalized, and the rest of PDB inherits that kind of uniformity, with the idea that PDB is just applying a local pattern, not trying to be authoritative in promoting a "canonical" way of writing each term. WinChloe has similar policy: Take & Make. YACPDB has Take&MakeChess. Search engines divide up words into atoms, so when I ask google for take&make I get "Take & Make" & "Take&Make" almost equally, so Google is blind to the distinct form that you prefer. Sorry.

Schwarz hat zuletzt f7-f5 gezogen, da d7-d5 an der retrograden Einsperrung des Lc8 scheitert.
Henrik Juel: C+ Popeye 4.61 after analysis
Analysis
White is missing one man, so last move was not a pawn capture
White pawns captured all six missing black men, so last move was not d7-d5
Obviously last move was not made by Ke7 or Sd8f8, so last move was f7-f5 legitimizing the ep key (2020-11-02)
