The only 'Rundlauf' or ... switchback (?) I knew is this one:
Theodor Nissl 1910
White to move, mate in six.
Any more examples? I like the theme.
Here are a few Mate-in-4-miniature-rundlaufs for you.
White: Ka4, Rc7, Bb5, Nd7; Black: Ka8, Na7, Ne3.
White: Ka1, Rb6, Nb1; Black: Ka4, Pa6.
C. G. S. Narayanan
White: Kg3, Qh1; Black: Kg5, Pf6, Pg4, Pg6.
And one final rundlauf dedicated to SwissGambit
Itamar Faybish / Göran Wicklund / François Labelle & Alexandre Leroux
Proof game in 13.5 moves.
