One of the games I learned from that old card games rule book was Canfield. What I remembered to Google the name was four cards wide and hard as hell. Game also known as Demon because it is so hard. I like the small playing field.

When I was in high school I would play the standard solitaire game for hours at a time while sitting in front of the TV. It became too easy. I had an old card games rule book (black one shown above) and I learned how to play all of the other solitaire games they had in that book, including several that used two decks. Two I remember were Spider and Napoleon at St. Helens. Some were very hard. I have a couple of decks sitting on the coffee table and I will occasionally deal out a few hands of the standard game while I am watching something. Usually late night. Like now watching Darkman on DVD.
