The Nature of Chunks

The debate is about the nature of chess chunks. One possibility states that chunks are built by encoding particular combinations of pieces-on-squares (POSs), and that chunks are formed mostly by “close” pieces (in a “Euclidean” sense). A complementary hypothesis, as proposed by Alexandre Linhares and Paulo Brum ^[6] , is that chunks are encoded by abstract, semantic information such as given in following positions, the Fool's mate and its “most economical” representation, as given by Jenő Bán ^[7] :
