I found a gem on the FMJD website, it is an article titled Checkers
by John Reade. It is a four page description
of Anglo-American Checkers that is clear and concise. I like that it contains the two kings against one king problem,
as it shows the precision of even the simplest tasks in checkers, and also the small edge you need for victory compared
to 10x10 International Checkers. Two sample games are given. The first game is a Single Corner from William Payne from 1756, and contains a note on the goose walk trap. The second game is the famous Wyllie vs Martins repeat game from 1863, with a Glasgow opening that is very effective against the Cracker Barrel computer. The 1863 game in the article does have an ending that is different from what I am familiar with. The article goes on to First Position, a mega study in itself. The solution given was a surprise to me, and convinces me more than ever to play out those endings! The article ends with American Position, while First Position involves the double corner, American Position involves the single corner.
