Implementation Notes

• Explanation of Change
  Implements 1850jr, a small 1830 clone from 1995 that was originally published in an Italian fanzine. BGG link. I reached out to the designer via BGG and got his permission. Screenshot of geekmail below.

Maybe just a curiosity of a game, but I played a couple of hotseat games and there were at least a few interesting moments.
