Sally: Weshalb aber geht dieletzte Variante auch nicht in den Diagrammen a) und b)?. Weil Weiß bei blockierender Stellung des Lh3 (sB4) zuletzt eindeutig oder mit dem König gezogen haben muss, was die Rochade verbieten würde. (2018-6-24)
Henrik Juel: If you dislike 'ferner', part c) could be written as 'sBg4 nach a2'
Analysis: last move was made by Ke1 or Ta1 in diagram position and in part b), so castling is possible in part c) only
C+ by Popeye 4.61 (2018-6-24)
