Battlegrounds of the Romans...
The intent is to collect games that contain d3 instead of d4. White may play c3 or Nc3 with d3. Fredthebear has zipped through a ton of Italian games of all varieties. Italian games with various move orders are easy to misplace, and some are mislabeled originally.
This collection has not been completely edited since changes were made, so a mix still exists. For example, the Evans Gambits need removed, but they're not hurting anything for now.

"Gioachino Greco (1600 – 1634) was an Italian chess player and writer who recorded some of the earliest known chess games. He was the first to use the initials NN to describe an anonymous opponent and his writings are said to have influenced many future Grandmasters. His rivals and chess comrades of the day were Ruy Lopez de Segura and Francois-Andre Danican Philidor, both legendary and influential players in their own right. Mikhail Botvinnik considered Greco to be the first professional chess player.
He played chess during the age of the “Italian Romantic Style”, for which he studied the Giuoco Piano (1.e4 e5 2.Nf3 Nc6 3.Bc4) and published his analysis in the form of short games around 1625. These games are regarded as classics of early chess literature and some are still taught to beginners today. What a legacy – to continue influencing the chess community almost 400 years later!"
