"Ah. Well. There's not much to be done about the board, of course, so that I have to keep track of in my head."

He gestures to the strangely arrayed cards on the table.

"As there's no need for the pieces to match, I was able to assemble the two sets using multiple decks. Red suits for white, black suits for black."

"Kings and queens are self-explanatory, of course. Jacks for knights, aces for bishops, tens for rooks. Numbered cards for the pawns, no particular need to differentiate."

He looks back to Obi-Wan and shrugs.

"It seemed far more productive than attempting solitaire with missing pieces."

This is the most animated his voice has been during the entire conversation, although it's still very quiet and tense. He clearly wasn't kidding about needing to take his mind off of things.

"I'll admit, I'm actually not much of a chess player."
