Murray writes, “This work follows the model of Salvio in containing Openings and problems or End-games, but it is far in advance of it, both in arrangement and in the accuracy and importance of the analysis… As an introduction to the Openings del Rio’s work was far superior to any work in existence in 1750, but it was admittedly written for advanced players.”

This is possibly the rarest 18th-century chess book.
