A.Buchanan: This kind of problem is traditionally in PDB placed in the mathematics genre, rather than fairy, because it involves, you know, counting stuff (2020-11-22)

(Der Preisbericht erschien auf der Website von Abdelaziz Onkoud Ende August 2020.)
Tries:
1. e5 Rb1?
2. e4 Rb5
3.axb5 is surprisingly too slow!

1. e5 Ra3? fails because of the white king standing around in the way.
1. e5 Rd1? also fails because of the white king standing around in the way.
Mirko Degenkolbe: Dies ist das zuglängste korrekte orthodoxe Hilfsmatt, in dem Weiß im ersten Zuge die Rochade ausführt. (2020-10-03)

A.Buchanan: The final move "Txg5#" was now correctly marked as an error, because it was ambiguous. Thanks Gerd! (2020-11-14)

Record for the shortest possible mutual stalemate

https://timkr.home.xs4all.nl/chess2/diary19txt.htm
Henrik Juel: This non-unique proof game is probably the shortest to reach the diagram position (2020-11-17)
Mario Richter: For a detailed history of the hunt for the shortest PG see Enzo's interesting article "Nuovo record nello stallo reciproco" in 'Best Problems" Nr. 44 (issue 04/2007).
Btw., most sources call this a "double-stalemate" (not "mutual") ... (2020-11-18)
Mario Richter: s. http://www.bestproblems.it/bppdf/BP044.pdf (2020-11-18)
A.Buchanan: That is probably very difficult to find and unlikely that many unique proof games can exist of that form (2020-11-19)
James Malcom: I'm unaware of any unique PGS that end in a mutual stalemate, but surely it must be possible, who the genius may be. (2020-11-19)
A.Buchanan: We’re missing some keywords for stalemate and mutual stalemate objectives. Also what are construction task and record and what’s the difference? (2020-11-19)
