Luis Ramírez de Lucena

He is believed to be the son of humanist writer and diplomat Juan de Lucena.

[1] Lucena wrote the oldest surviving printed book on chess, Repetición de Amores y Arte de Ajedrez con CL [150] Juegos de Partido ("Repetition of Love and the Art of Playing Chess with 150 Games"), published in Salamanca around 1497.

[2] The book includes analysis of eleven chess openings but also contains many elementary errors that led chess historian H. J. R. Murray to suggest that it was prepared in a hurry.

Commentators have suggested that much of the material was copied from Francesc Vicent's now-lost 1495 work Libre dels jochs partits dels schacs en nombre de 100.

The smothered mate (later named Philidor's legacy) is in the book.
