I was very interested to see Lasker's Defense featured prominently in John Cox's just released Declining the Queen's Gambit (Everyman 2011), available from New in Chess. I don't think there has been a good book on the Lasker in over a decade, and certainly none from the Black perspective. Based on the excellent sample pages (in PDF or Zipped PDF files), which give the entire Lasker Defense chapter (thanks, Katar, for pointing that out), I'd say it looks like a great book and one which, together with Cox's earlier Dealing with d4 Deviations, offers a complete repertoire for Black against 1.d4. I look forward to reading it more closely.
