Paulo Brum,
a Brazilian computer scientist at Escola Brasileira de Administração Pública e de Empresas, Fundação Getúlio Vargas (FGV), Rio de Janeiro, who contributed along with Alexandre Linhares on cognition in chess, and the nature of chunking.

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 [1] , 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 [2] :
