I don't know
quite enough about Go (the name of that game) to say for certain, but it appears white is in an unwinnable (or very hard to win from) position on the board in the last panel, and that's why they called the game as 9
th's win (he was playing black). It's sort of a visual metaphor for their conversation - 9
th had the upper hand throughout, even from the start, where he pretended to have not secretly met his senior brother last night after the assassination attempt, and the concubine took it at face value. Even after that, he controlled the flow of the conversation to get the information he wanted and not give anything away.
What's
really interesting is that apparently the emperor was the one who started the game, and 9
th sat down, looked at the board state, grasped what the emperor had been doing, and carried it to enough of a close his opponent gave up.
Go is a game where you can put down one piece of your color every turn, and attempt to entirely surround your opponent's constructions to capture all the pieces in them, and enclose blank spaces to score them. It's absolutely fascinating, because the first several placements (and most of the seemingly obvious placements that aren't made down the line) look completely absurd to someone who doesn't understand the game, but there's a lot of mindgames and 'threatened territory' hiding in the wings. If chess strategy is a wolf leaping at you to tear your throat out, Go strategy is a bear encircling you with its arms to crush your ribcage. I'm no expert, but I've played it a bit, and it's kind of fun.
