The change of aim causes the replies to the king flights to move round in an ABC-BCA cycle, an idea known as the Lačný theme, after Slovak composer L’udovít Lačný (1926-2019).
Jacob Hoover: We have a 3x2 Lačný, but presented in a very unique and interesting way.
Richard Stein: A nifty cyclic theme, and the fact that both parts use the same key is a sneaky trick.
