I see, thanks for clarifying. I guess there are several ways to think of both: Flatland as described at normaldeviate.wordpress.com talks about the best place to look for a treasure, so in that way it is also about optimal strategy. And Monty Hall is about updating a prior belief about where the prize is, so (in my mind at least) they are both about priors and also both about optimal strategies.
