When Ron asked how Harry had nearly beaten him in chess, you had Harry mention Sabacc. Umm...Sabacc's a card game. The only board game I've seen in Star Wars is called dejarik (yes, it's the one Chewie and R2 were playing on the way to Alderaan).
After McGonnagall's reaction to finding those compulsions on Hermione, I wonder how many she's under.
Keep up the good work!
According to 'Han Solo at Stars End' by Brian Daley (1979), Sabbacc is a combination of luck, skill, and strategy. Reminds me of chess.
Also I didn't know the game R2D2 and Chewbacca were playing even had a name.
McGonagall is under quite a few, but the time hasn't come to let her go. That comes much later.
