Henrik Juel: Note that in problems castling acts like capture and pawn move with respect to the 50 moves rule. After 949.a6xSb7 there are 4 moves left by [Pa7]; but each camp can shift only KDT, on d1-g1 and b8-e8, respectively, so the triple repetition rule now limits the length of the game. (2004-09-09)
A.Buchanan: In some problems it's certainly the case that the 50-move rule operates incorrectly in this way. Such problems are fine, but obviously wouldn't want to impose this as a standard. Different composers can make different assumptions here (2023-06-20)

Welches waren die 12 Schlagfälle?
R: 1. ... Tc1xSd1 2. Sc3-d1 Tc2xLc1 3.
Henrik Juel: -1... Tc1xSd1 -2.Sc3 Tc2xLc1 etc.
The other black captures were f7xLg6 and g7xSh6.
White captured c2xPb3xPa4, g2xLf3, and h2xSg3xSf4xPe5xPd6xPc7.
Unusually easy for a Ceriani retro.
The record in this genre may be P1000077 ; does anyone know of a retro with less than 19 men in the diagram position and the stipulation 'What were the captures?' ? (2012-07-13)
James Malcom: What is the full solution? (2023-05-30)
Henrik Juel: The 12 captures are given in the first three lines of my 2012 comment
The further retroplay is easy and of little interest, I believe
James, you might want to change the initial retroplay to
R: 1. ... Tc1xSd1+ 2. Sc3-d1 Tc2xLc1+ etc.
(with uncheck plusses added) (2023-05-30)

Mario Richter: My assumption: a record construction for the ratio g/f with f=number of uniquely determined last moves, g=length of the shortest proof game (s. Fairy Chess Review No.9 28.Nov.1949, p.69 for an explanation), here we have 42/19 (2012-07-16)

A.Buchanan: I think it's perhaps a little disrespectful to describe the problem is "cooked" when there is no intention for the PG to be solution to be unique. It's certainly good to know that there is no shorter solution. (2023-03-25)
