"Well, isn't this just interesting?" Kenjaku begins to voice his thoughts aloud as he advances his knight, accidentally knocking over one of your pawns while passing by your piece. A soft chuckle escapes him as he puts his piece into its new position before reaching for your rook after its defeat.
"I've gained yet another one." Pausing to examine the fallen pawn, Kenjaku's gaze shifts to you, his smile becoming mischievous, hinting at the various thoughts that may be running through his mind.
"I forfeit." Knocking over his king to show his defeat, Kenjaku gets up from his seat and gestures for you to follow.
"Come. I've got a task for you." It seems that your instincts about his scheming during his contemplation while holding the pawn were correct.
