1.exf3e.p. Bc2# is the only possible solution, but this necessitates R: 1.f2-f4. Can we prove this?

(13+13) with 1+2 pawn captures. Bf8 captured at home, so to satisfy White appetite, the missing Black pawn (a or b) must have promoted via c2 on c1. Two more White units must be captured to allow this.

The kings cage can only be unlocked by retracting WPc2. But the clock is ticking as there are only 6 black moves which can be retracted.

The promoted piece was captured on e3 or h3. If either capture is undone, then a White bishop square is cut off, so WB must be replaced prior to this.

Now the order of the early moves is: WdP moves, WQB & WQR escape, BP promotes on c1 to X (capturing WR at some point), X captured by WP.

So the first White capture must be dxNe3 and the second White capture releases gxXh3. The second White capture releases WKB & WKR. WKR captured by original BfP.

The clock starts ticking with gxh3. Black has 6 pawn moves. WKB has 3 moves to reach h7. WR has 3 if it goes via d file, or 2 if it starts on g1 (in which case WfP or WQB must also move once). So certainly at least 6 White moves. Last move was therefore White (even if the stipulation didn't tell us), and it can only have been WfP coming from f3 or f4. If it had been coming from f3 it would have blocked WKB in its progress, so the last White move was indeed R: 1.f2-f4.

WKR did therefore move from g1-g4-e4, and R: 1. ... fxRe5 2. Rg4-e4. Prior to that, move order not unique, but counting still exact.

Note that WN loitering on b4, pretending to be part of the cage, is present on the board just to make up the numbers.
Jeliss: "Obstruction of passage square f3 to Bishop of same colour."

"Version 'Pittsburgh Leader' 08.06.1913"
Yoav Ben-Zvi: Appears as the first problem (D445) in the booklet on Dawson's RA problems by G.P. Jellis. The obstruction that occurs in the Try -1.Pf3-f4?, by WP of WB, is described as "obstruction of passage square". It is not considered by Dawson and his disciples to be a Retro opposition. Dawson's conception of RO was quite broad, it included cases where the interference was not by occupation of the target square, so the only valid reason that I can see to exclude this case is that the 2 pieces involved are both of the same color. Fabel's definition explicitly excludes "Monochrome RO". I conclude that it would be preferrable to interpret RO as a bi-chromatic interference. The keyword Retro opposition should be removed. (2018-04-07)
A.Buchanan: To my mind, RO involves some kind of parity-tempo issue between the sides, not just some kind of race-tempo. If it was just about "bi-chromatic interference", one might say that bPe4 blocks wBh7 from an immediate retreat, so it has to be wPf4 that retreats first, legitimizing the ep key. So I agree this is not RO. (2024-01-06)

A.C. White: "He [Loyd] cared little for the means he used, so long as his results were successful. And, strangely enough, it almost seems as though his results were increasingly successful and all the more artistic when he took the most radical liberties with the conventional theories of composition. ... It is certainly not considered good form to reply to a check by Black with a direct capture. To do so is recognised as crude, obvious and unscientific. But Loyd's genius thought little of theory, giving all its attention to practice. And his results justified his independence. These problems are among his very best. The key of No. 581 is one of the most puzzling in all two-move composition, subtle, artistic and scientific in the highest measure; and the mates blend with it most beautifully."

'Sam Loyd and his chess Problems': "The interception of the line of action of the Black pieces by White leads to some pretty effects, but in general they are less striking than the effects produced by a similar interception by Black. The reason for this doubtless is that when the Blacks interfere with their own pieces they do so against their will, because the enemy has in some way or other lured or forced them into a trap. On the other hand when it is White who interferes with Black, it is usually a case of direct attack combined with malice aforethought. It may be cleverly devised and it may be well hidden, but a theme which depends for its effect mainly on the moves of White's attack can never have the charm or the unexpectedness of one which is developed through the defensive efforts of Black. Take No. 436 It is clear that removing the White Rook threatens 2 Qb1 mate. Black's obvious replies would be 1. ... B x P or 1. ... P x Q. This readily suggests 1. Rc6 to be the key, because in no other way could White give the two necessary diagonal mates (2. QxP mate and 2. PxB=Q mate) which the Black Queen and Rooks are all in position to defeat. A cut-off key of this sort is better disguised in a three-move problem, as the Black defenses that have to be prevented are less easily seen."
