Actually, no! I was kind of hoping that by reading this section, I might find out about them. Why write a blog post section specifically targeted at those readers for whom it holds no new information? The responsible thing to do here, if you really didn't feel like explaining some key component of your discussion, would have been to provide a reference to someone else's explanation. Now it feels like you were wasting my time -- 'oh, hey kid, wasn't talking to you!'

Also, as others above have mentioned, the generalized introduction (a way to make 2 losing games into a winner!) does not lead intuitively into the extremely case-specific exposition.
