=The Nature of Chunks= There is a debate 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, 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 [|Ban] : /RNBQKBNR w KQkq - ||~  ||= 8/8/8/8/8/6b1/2k1P3/4KB2 w - - ||
