Yoav Ben-Zvi (The Problemist, 05/2017): The key by the White queen crosses c4, a Critical effect that is negative as it prevents the mate by P-c4 in response to random moves by bNc5 and bBb5, and also crosses e4, an Anticritical effect that is positive as it allows the mate by Pe4 in response to the same random moves. Correction moves by bB in the Set play and by bN in the solution lead to reciprocal change of mates with those in response to the random moves.

SBD (2013-08-09): A remarkably similar idea to P1040360, Sophie Schett, Schachminiaturen 1903 with the sacrifice of a knight rather than a bishop.

Doppelte AUW in einem langzügigen Serienzugselbstmatt, da kann man nur mit Mutter Kempowski sagen: "Wie isses nur möglich!". Kein Wort, nur tief durchatmen und staunen! (Preisrichter Theodor Steudel).
