I believe “satisfyingly” would work, the definition of satisfyingly is: “in a way that gives fulfillment or the pleasure associated with this.” The definition of “proudly” is: “with a feeling of deep pleasure or satisfaction in one's own achievements, qualities, or possessions or those of someone with whom one is closely associated.” The word satisfy is used in the definition so I believe they are similar!
Borges's story The Garden of Forking Paths can be considered to be a three dimensional chess game for a variety of reasons. First, like a game of chess, a nearly infinite number of possible outcomes are proposed through the story (just as how a chess game can allow for a variety of different outcomes). Also, chess is a game of choice, just as the Garden of Forking Paths - both the story itself and the novel of the same titles mentioned in the story - allows for the reader to, in essence, choose their own design and strategy. Furthermore, the lead character\protagonist in the story is manipulating events throughout the story to, in essence, score a "checkmate."
