> You can't ask what hint Alice gave to Bob on her previous turn
This sounds like reading the rules too stringently and not by their intent if you ask me, since it is asking only about information that the person is supposed to know.
It would be like saying if someone asks what the rules of the game are you aren't allowed to answer because none of the rules explicitly state that you can convey information about the rules of the game.
The point is that the other player may wonder: "why are they warning me about that rule right now? Do they see that based on how we are playing, someone is going to misplay soon?"
That leaks the players information state. Proper Hanabi is played with AI, who can't feel how boring the game is when played correctly.
Considering we are discussing card games, Chairman Mao would have been the more logical game to bring up. Unlike paranoia, but like Hanabi, it's a game for insufferable people.
