I was geatly amused when at the very end, as the two chessplayers are riding off, the Rifleman's son Mark says, "Golly Pa, I'd sure like to do that!"
"Play chess?" Pa asks.
"No," Mark replies.
I also noted that in 1880 they somehow got ahold of one of those Renaissance sets from the distant future.
For fun and giggles, review and enjoy this episode of The Rifleman that features chess. It's from 1961, a period when western themes still ruled the airwaves.
The chess part comes later in the episode but why not watch it all.
