Cook: R: 34. ... Lc7-d6 35. Bd6xDc5 Db4-c5,Db3-c5,Db5-c5 dann 1. Dxb7#
Mario Richter: How about R: 34. ... Lc7-d6 35. Bd6xDc5 Db4-c5, 1. Dxb7#? (2021-02-16)
A.Buchanan: Well spotted, Mario. The first 33.5 retractions are clear but then there is a bit more flexibility. Can sLg7 be shifted to b6? I don’t think it’s actually needed in the former location. (2021-02-17)
Mario Richter: For me, this dual makes the problem cooked.

I think that shifting sLg7 to b6 doesn't help (e.g. it allows the Bishop to uncapture the white pawn ob a5) (2021-02-17)
A.Buchanan: Sorry I wasn't trying to imply that the "flexibility" is tolerable: it's definitely cooked. Without the clock ticking for the mate, there is no unique retraction at all, as Black pieces can just wander all over. I don't suppose we can shift sBb7 to b6? (2021-02-17)
Mario Richter: No, shifting sBb7 to b6 allows a black rook to temporarily occupy b7, thereby giving wLd6 the opportunity for tempo moves, e.g. R: 1. ... Tc7-c8 2. Ka8-b8 Tb7-c7 3. Lb8-d6 Kc8-d8 4. Ld6-b8 Td8-d7 5. Lc7-d6 Te8-d8 6. Lb8-c7 Td7-b7 7. Ld6-b8 Kd8-c8 8. Kb8-a8, dann 1. Lc7# (2021-02-17)
A.Buchanan: I have some other ideas: but even I can see that none of them work. OK this one is cooked. (2021-02-17)

A.Buchanan: This is a cool problem with tempo loss for both players (bK9 & wPf2). Noam likes to end proof games with checkmate, and in this case I guess it serves to eliminate shorter solutions which would otherwise save half a move. Checking 16.5 is sufficient for soundness. Thanks for taking the time to test. (2023-01-11)
A.Buchanan: Bit baffled how there can be 64 solutions in 18.0 moves since White just moved. 18.5 maybe? (2023-01-11)
ras@bsiag.com: Quickly checked because 45h seemed a lot for only 17.5 moves and only a few captures: Stelvio 0.98 is done in 210 seconds. (2023-01-11)
ras@bsiag.com: Well, Stelvio treats shorter solutions of same parity as cooks, so any shorter solution in 16.5, 15.5 etc would have been found by checking for 17.5. But anyhow, quickly checking 16.5 is done in a few seconds, finding no solution (of course). (2023-01-12)

PR M.Caillaud: According to Winchloe, a complete diagonal by a King is a novelty. The trick to start from h8 is nice. Travel on the 1st rank is a valuable thematical addition. I wish the composer could improve it to make a straight line (f1-g1-h1) in order to produce a more striking visual effect (even if with less thematical moves).
