On the other hand, maybe being “logically omniscient,” the guesser would inevitably conclude that a codebook is the only reasonable scheme, and that would outweigh the enormous coincidence of the 5-character string being a valid name.
I don’t think this would be true because the string chooser picks a string after they know which person they are trying to point to
So, given that they need to point to Wei Yi, they might choose to use the name instead of the Schelling codebook if the Schelling codebook has a lower success probability than the name (even if the Schelling point is quite unique!). This is not a repeated game.
It’s hard to say what a UDT agent would do, though. It could go either way.
