play all play one stop play next play all
Aber nach 11. Lh1 kann Weiß auch g2xLh3 zurücknehmen!
Cook: gxsLh3!
Henrik Juel: 1.d5-d4-d3-d2-d1B-b3xa2-c4-f1 10.Bg2-h1 12.fxg3ep+?? fxg3# seems to fail, because after 11.Bh1 last move could be g2xh3. So what is the solution? (2003-04-28)
Thierry LE GLEUHER: After 11.Bh1, the last move can't be g2xh3 because of the promoted Bishop h1 imcompatible with the bP structure! (2005-09-25)
Henrik Juel: Why couldn't Black have a promoted bishop at this point in time (where wPa2 and bPd7 are no longer present)? 12 captures by black pawns seem to match the 12 missing white men. (2005-09-26)
Joost de Heer: Besides, after g2-g4, the black bishop must've been promoted too. (2005-09-30)
James Malcom: Henrik, gxh3 is indeed impossible. The last move sequence must go something like 1. Kfg8 Se2+ 2. Kh2 Sg1. There cannot be a knight on h3, cutting off g8, or a queen/rook, cutting off h2. Thus, gxh3 has already been played and g2-g4 is the last move. (2021-09-14)
Mario Richter: Position after 11. Lh1 is 8/5p2/8/5ppp/5pPk/5p1P/5P1K/6nb.
It can be easily shown, that in this position g2xLh3! is indeed a legal retraction.
So the ep-capture is not justified and the problem is cooked!
(Perhaps Thierry forgot, that black pawn d7 "disappeared"? But Joost's argument raises [correctly] the question, why a promoted Bishop on h1 is ok for g2-g4, but not for g2xLh3.) (2021-09-15)
Henrik Juel: So the good guys (Mario, Joost, and me) win over the bad ones (Thierry and James) by 3-2... (2021-09-15)
Henrik Juel: or, less insultingly:
By a majority of 3 to 2 this problem has been deemed cooked (2021-09-15)
James Malcom: Make it 4 to 1: 1. Nc3 Nf6 2. Nd5 Rg8 3. Nxf6+ exf6 4. d4 Ke7 5. Bg5 fxg5 6. Nf3 Kf6 7. Ne5 Bd6 8. Nc6 Bg3 9. hxg3 bxc6 10.

Kh2 Ng1 40. gxh3 (2021-09-16)
A.Buchanan: Is it also possible that in the critical position, the last moves were R: 1.gxSh3 exXf345 2.X~? I think I can fix the cook R: 1.gxLh3 nicely. (2021-09-17)

Bob Baker: I'm not sure how this suggestion should be submitted. In the link to the explanation of Pocket Pieces in English, "whicht" should be "which", "turnto" should be "turn to", and "No piece must be taken" should be "No piece may be taken". (2023-11-01)

Henrik Juel: Black makes 15 captures.
The first 16.0 moves are correct by Euclide 1.0; but it takes some 14 minutes, so a complete test would probably take days (2014-12-09)

It's a long way to Tipperary, it's a long way to go (\eb).
Bis zum bitteren Ende. Ein netter Anticirce-Witz (WWi).
Da bin ich beim Zählen fast eingeschlafen, bis ich erkannt habe,
daß es mit multiplizieren auch geht (MN).
Eine fein säuberlich verschnürte Seeschlange! Die Diagrammstellung
ist übrigens anticirce-legal! Die schlichteste aller
Märchenschach-Legalitäts-Konventionen, nämlich "`Märchenbedingung
ab Diagramm, vorher orthodoxes Hilfsspiel"', greift gelegentlich zu
kurz so wie hier (LZ). Der Mann wird mir mit seinen Ideen langsam
unheimlich. Toll, dieser mehrfache 90\%-Exzelsior (NG).

a) The four pieces which move reveal their colours. So with 2. ... cxb7# delivers check to bK, whichever it turns it to be! All other flight squares are covered by wK, wLb6 & if necessary sSd7.
b) Now wK, wDb8 & (if necessary) sTd7 cover the flight squares.

Synthese-Meeraner (im Selbstmatt), Themafigur: sL
[MD 1607]
In the starting position there is an immediate set matt.
But this cannot be maintained by white.
That's why he has to come up with something new.
In order to restore the starting position and thereby shift the duty to move to black, White needs ten moves.
The black king has to run two linear Rundlaufs and the white queen must be led a tempo onto the square d6. Only when all of this has been implemented can white S and white Q return to their original stands, forcing black to set the mat.
Model mate.

Sie muss unter ständiger Beobachtung des schwarzen Königs den sBa7 dazu zwingen, dass er nach a2 läuft. Dabei muss die Dame genau spielen, denn beispielsweise das Feld g2 ist ein absolutes Tabu für sie.

Unique set play retro try in the retro twin s). 1.Kc7 axb7 2.Kd8 b8=D#. Zero set play in b).
All pieces are necessary for soundness in at least one twin except for sBa4 ("the manager").
First publication had typo in stipulation
Henrik Juel: If you disregard retro considerations and blindly test with Popeye 4.61, you get lots of cooks in part a) and 1.Re7-c7 e6-e7 2.Kc6-d7 Ke4-d5 3.Kd7-c8 e7-e8=Q #
in part b) (2023-05-20)
Henrik Juel: Part b) is OK, because last move could be Kd4-e4, and a normal h#3 ensues
But in part a) White (not Black as intimated by the Keyword) has no last move, and the stipulation changes to h#2.5 with the solution 1...a6*b7 2.Kc6-c7 Ke4-d5 3.Kc7-d8 b7-b8=Q #

Henrik Juel: Die Schwalbe Märchenschachlexikon says
Psycho: A rotating combination of Rook, Bishop and Knight, which continually surrenders (temporarily) the power last used. Thus, there are three distinct Psycho pieces (separate pieces, not merely states, for Madrasi/Isardam purposes): Psycho-Rook (PR): B+S powers (not R) - last move was orthogonal. Psycho-Bishop (PB): R+S powers (not B) - last move was diagonal. Psycho-Knight (PS): R+B powers (not S) - last move was (2:1) leap. Upon moving, psychos immediately change into: PR after moving orthogonally, PB after moving diagonally, PS after leap. Psychos may not be used for castling. (e.g., Upon moving as Rook, a psycho-Bishop becomes a psycho-Rook, which has the powers of Bishop and Knight: pBa1-a8=pR.) Castling with a psycho is not legal. When any form of psycho is present, promotions to all forms of psycho are allowed. (2023-12-22)
Kevin Begley: FYI: The game of the psycho-Queen (a fairy condition using these units) starts with a psycho-Queen (which starts with all three powers: Rook, Bishop, and Knight, but upon moving it descends into one of the three psycho units described above (psycho-Rook, psycho-Bishop, or psycho-Knight). It can be played on an 8x8 board, though intended for a special board (8 ranks, 10 files, remove the corner squares) inspired by Frank Vigor Morley's "My One Contribution to Chess). There are various pawn promotion options, but I now favor promotion on the last square of the file (7th rank for pawns on an edge file) to psycho-Queen, Rook, Bishop, Knight (but NOT to psycho-Rook, psycho-Bishop, or psycho-Knight).
