Yet this article, like thousand others, don't go beyond binary decisions. Binary decisions are fine for many everyday decisions like figuring out whether to get insurance[1] but the Kelly criterion goes well beyond that[2] without changing the fundamentals: estimate a joint probability distribution of the outcome for each alternative, evaluate E(log X) using it, and pick the alternative for which it is highest.
For a deeper introduction, I recommend the somewhat heavy Kelly Capital Growth Investment Criterion[3] which is a well-curated collection of papers on the Kelly criterion and its various uses.
