Rinaldo Bianchetti (Genoa, November 17, 1882 – Ruta di Camogli, November 21, 1963) was an Italian chess player, chess composer, and honorary master.

Biography
He was an industrial engineer by profession and attended the Genoa Chess Club as a young man. He wrote over a hundred studies, particularly on kings and pawns.

In 1925, he published a monograph entitled "Contribution to the Theory of Endgames of Soli Pawns," in which he further developed the theory of reciprocal squares originally introduced by Edward Cecil Tattersall. Bianchetti's book was plagiarized and translated into French under the names of Marcel Duchamp and Vitaly Halberstadt.

A friend of the French scholar Henri Rinck, he is considered one of the most profound analysts of the first half of the 20th century.

From 1923 to 1926 and then from 1946 to 1957 he was editor of the studies section of the journal L'Italia Scacchiistica .
