Nach 1.Kc1 ... 6.a8=D Kb5! braucht Weiss noch 48 Züge bis zum s#.
Mit der Stellungsveränderung sBc7 nach c5 ist es ein s#45 (mit den bei Blathy üblichen Dualen) (2020-11-14)

Olaf Jenkner: See "Das längste Selbstmatt" (Die Schwalbe June 2005):
The stipulation is s#340, Mintz's correction was published 1986.
The problem is cooked in 330 moves.
The longest correct selfmate is s#255 (P1091383) (2015-01-01)
Olaf Jenkner: The matrix was invented 1903 by William A. Shinkman. (2015-01-01)
A.Buchanan: Should the keyword be renamed then? How is it generally known? (2015-01-03)
Olaf Jenkner: In my opinion yes. We should ask Frank Müller. (2015-01-03)
Frank Müller: Ich darf dazu Sir Jeremy Morse in The Problemist July 2006, Seite 430, zitieren: "... and it now seems right to call it the 'Shinkman-Bláthy-matrix'. (2015-01-03)
A.Buchanan: OK thanks: I have renamed the keyword. Detail: I have now set up both the author and the keyword so that (1) they will appear with the Hungarian diacritical "á", but (2) they can be searched with either "á" or "a" (or wildcard "%" of course). I had set up "Høeg" the same way recently, and it seems to work. Please tell me if there are any issues. (2015-01-03)
