[Retros] Die Schwalbe 229 - problem 13635

[raosorio at fibertel.com.ar]

Hi,
Motivated by an Andrew Buchanan's question, I consider apropiated to show this
problem with the original stipulation in english, avoiding the loop english-german-
english. There are a couple of very subttle differences: a) LEGAL circuits , where the word
legal reinforces the idea;  b).....THE maximal number.... , instead of .....A maximal number....

Circuits means no more that the straight interpretation: From c2 to c8 and back to c2.
How many moves is free, but there is a logical conection with the question.
