I already watched Kaguya-sama. Most of it wasn't very impressive but the part with the umbrella was amazing. The characters playing mind games switched goals too quickly. For example, I remember they were playing mental chess but then the narrator said their energy was drained and they both wanted the food on the table (there was only one food item) and the victory condition changed from outwitting the other into grabbing the food first.

You uploaded Ted Chiang's understand, which I read before. I would ask for mind game books but this is an anime board and I don't wish to talk of an off-board topic.
