Michael Keller is specialized in two- and threemovers.

The Keller paradox is a direct mover theme that requests that "White moves to a square just controlled (or controlled again) by Black."
In 1994 Friedrich Chlubna wrote the collection "Michael Keller. Ein Meister der Schachkomposition" comprising 279 problems by Keller.

On Wikipedia you may see an excellent and strategically very rich threemover of his. Of course Michael Keller composed many beautiful problems, but here is a typical one:
