Before Dungeons & Dragons, the kernel of the rules for that game were presented in a wargame called Chainmail (1971) by co-author Gary Gygax. This rulebook had a mini-game for Jousting, which I formally solved in 2022. I had the opportunity to present this at the Computers and Games conference (CG 2022), and it was recently published by Springer in the volume below (link):
