Composers: The content demonstrates one Ceriani-Frolkin rook with thematic square c8, two with thematic square e8, as well as the two original rooks both visiting square e8 (anti-Pronkin). It is now generally accepted that only one ‘supporting’ Ceriani-Frolkin is needed while performing two-fold anti-Pronkin theme on the same thematic square. In particular the second Ceriani-Frolkin with thematic square e8 is not involved in de the double anti-Pronkin part of the entry, and hence should be considered as thematic in itself.
This implies that the full thematic content is two anti-Pronkin rooks on the same square e8, as well as two Ceriani-Frolkin rooks on squares c8 and e8, respectively. This very new, difficult and homogeneous combination was our primary intention – it is symbolized, in the future proof game language developed in the special issue Die Schwalbe 250A, by the notation AP(R,R) & CF(R,R).
Concerning the construction, one has to ensure that the thematic captured pieces are the promoted ones and not the original ones (rebirthed after promotion). This is done here with the white g-pawn standing on g7 and the visible promoted Qg6. This couple may be constructed only when the three black captures gxh6, fxg6xh5 have already occured, and rather early in the game, as the above mentioned Queen is necessarily the first black promotion – among the 3 – which left its thematic square. We hope that it is enough to ensure the soundness of the entry.
Concerning computer analysis, this is over for Euclide after 24. Bg2 (Natch may go a bit further but not much) mainly because both programs are considering that after 24. … Rfg3, this rook may arrive to g3 in 2 moves (probably jumping over the white g-pawn!) This obviously could not be considered as a bug, but certainly as a flaw from those programs. The remaining part of our proof game has been checked with Popeye, using the a=b command. (2016-03-25)
Reto: Stelvio finds the solution quite quickly with v1.17 but full resolution would take weeks if not months with the current code. I'll retry this when Stelvio has improved further. (2023-04-17)

It is a fine demonstration of the potential of the fairy condition Disparate. In the solution, a white promotion (into piece X) occurs on square c8 before any move of [Qd8] or [Ke8]. The following move Qd7 proves that X is not a rook (it can still be a queen because of the fairy condition!). The immediately following move Ke7 proves that X is not a knight. Then Ke6 is played, followed by a move by Qd7 which proves that X is not a bishop.
X thus can only be a queen! (We still have to show that the position is legal.) Only after completion of the proof, the promoted queen is captured. It is admirable that the author managed to compose a move sequence obeying all mentioned constraints concerning the move order. A rich demonstration of the fairy condition, exciting to solve.
Henrik Juel: Definition of Disparate from Julia's Fairies:
If one side makes a move with a piece of type “x” (black, white,neutral, half-neutral, etc., King included), the other side cannot answer immediately by moving a piece of the same type “x”.). A pawn promoting is a pawn move.
To me, it is not clear from the definition that 9.c8 is undetermined, and only later is inferred to be 9.c8=Q
Why can White not decide to promote to queen? (2017-03-18)
Henrik Juel: I misunderstood your text, Vlaicu
Now I see that White indeed decides to promote to queen, and your argument shows why the other promotion choices do not work in this proof game (2017-03-18)
Henrik Juel: ... even though the promoted man never moves (2017-03-18)
paul: Jacobi checked the last 12 moves and gave unique solution.

Duplicate Diagram: P1214056

Judge's comment [Kostas Prentos]: "This is not the first quadruple Pronkin in a proof game; Nicolas has published a few, already. It is the first time that one of the four thematic pieces, the wQ, is captured at home, and is replaced by a new Pronkin Queen. The promoted black Bishops are an effective, but unpleasant alternative to the standard method of doubled pawns that usually come with this theme. In this case, the capture on d1 is thematic, and that on a1, forgivable, considering that it takes 5 moves to reestablish the Rook on a1. On the plus side, all the surviving white army has resumed the initial position."
