The line is the subject of Chapter 3 of Alexei Kornev's book Play 1.d4 d5 2.c4 e6!, published by Chess Stars. The contents page of the book is available at the link. It's a repertoire book from Black's perspective. Kornev writes that after 5.e4 "Black must find several very precise moves in order to reach equality".


Since White gets a significant advantage at once with with 5.e4, I doubt that anyone has ever written a book about it.

  • But isn't this kind of similar to the Semi-Tarrasch, which someone has probably written a book about?

    Worth mentioning that some top players do play it occasionally, especially at rapid time controls. Kramnik has a dozen or so games as black. Way less bad than 1.d4 d5 2. c4 Nf6 3. cxd5 Nxd5 for example. Stockfish gives it +0.3 or so. Commented Aug 2, 2023 at 16:37
  • Indeed it has been played, but without much success. Lichess gives the WDL percentages as 37-47-16. Books have certainly been written about openings that may be worse, like 1.e4 e5 2.Nf3 f5, but those are tricky and interesting. If I were an author I would not find this an exciting project.

  • I think those percentages are for the 4...exd5 variation.

  • Interesting to see the line appearing in today's World Cup classical game between the Muzychuk sisters: chess24.com/en/watch/live-tournaments/… Commented Aug 9, 2023 at 14:26
