I mean you didn't understand what the characters themselves were talking about. Kakashi had just finished explaining to Naruto about Nature Transformation, and Naruto was asking about all the other non-elemental jutsu. That's when Kakashi mentioned Yin and Yang release. as far as Shikamru's comment "Specialized Chakra" can mean anything, but in this case I am fairly sure he was talking about chakra with an unusual composition. Like Being made almost entirely of the spiritual component of chakra.
