On the basis of a peculiar chess puzzle, the paper presents an analysis of a more general philosophical problem, which links chess with ontology and phenomenology, namely the problem of the ontological status of a chess piece. In The Controversy over the Existence of the World, Roman Ingarden presents the most complete study of this problem, as well as several other problems related to it which might be generally characterized as the fundamentals of the philosophy of chess. The presentation of Ingarden's considerations is supplemented by comments taken from works of other thinkers such as Husserl, Searle or Smullyan.
