So if you look at the josekipedia entry, you can see that it offers two alternatives after the white attachment (played by black in your game) - follow those lines further, both are refutations of the overplay. You can either push up and split, leaving you with a big corner (http://josekipedia.com/#path:qdodmdqepdpeocncndoeob), or you can hane and then crawl, leaving your opponent with no base and pressure from the pincering stone (http://josekipedia.com/#path:qdodmdqereperf).
Although it seems to you that the attachment attacks your stone and grabs the corner, actually the knight's move is very cuttable. Either you cut it, or your opponent defends it - either is good for you.
[edit: it looks like you considered the push up response in your own review - good! - but you rejected it because it looked like bad shape maybe? just one more move was needed and things started looking good for you.]
By the way, you say your pincer was a mistake, but it looks totally fine to me
