Mastering the Najdorf

My brother and Javier Moreno recently finished a book (my brother's first), titled "Mastering the Najdorf". The content is rather cryptic (it's an advanced book on chess), so I just keep it on the shelf and page through it now and then (maybe hoping some of it will sink in subconsciously). Nonetheless, it's very cool to see my little bro's name on the binding.
