Gioachino Greco was an Italian chess player and writer. He recorded some of the earliest chess games known. His games, all against anonymous opponents ("NN"), were quite possibly constructs (Hooper & Whyld 1992), but served as highly useful tools for spotting opening traps.
Mikhail Botvinnik considered Greco to be the first professional chess player (Gufeld & Stetsko 1996:5).
Gioacchino Greco was also known in Italy as "il Calabrese", which means "the Calabrian". Some sources quote that his parents were Greeks and that he had been born at Celico, a village near Cosenza (Murray 2012:828).
