I know 6...Be7 was played by some strong players recently, but it looks silly. What's the concept behind it?


I think the idea is that if White plays 7 dxe5, you don't need to play b7-b5 and can play 7... Nc5 or possibly 7... 0-0 8 c3 d5

Or 7 Re1 b5 8 Bb3 d5 9 dxe5, White is forced into an Open Ruy Lopez with Re1 which is not considered the most critical.

So often White is going for 7 Re1 b5 8 Rxe4 d5 9 Nxe5 Nxe5 10 Rxe5 bxa4 with a unique position ... there is a fair bit of analysis on the main Chesspublishing.com site.

Unfortunately, after 9...Nc5 10. c3 Be7 11. Bc2 d4 13. Nb3 d3, if White bails out with 13. Nxc5 dxc2 14. Qxd8+ Rxd8 15. Nxe6 fxe6 16. Be3 Rd5 17. Rfc1 Nxe5 18. Nxe5 Rxe5 19. Rxc2, we arrive at a dry endgame where it feels like White is playing for two results.

If Black is just aiming to equalize, how do I even try for any winning chances? Marin's claim of "easy equality" just seems too rosy to be true.


I don't know if it is easy equality, haven't studied the line in depth. But Marin is much stronger than I am. I just got the course from Modern Chess, will check it out.

Anyway, maybe you'll have to deviate earlier, by 6...Be7 if you'd like something more imbalanced?

Unfortunately, that I don't really know. I have just noticed that the move seems to lead to positions that are not as "dry".

Marin's work is an ebook available at Modern-Chess.com. It seems to read in perfectly in either ChessBase or Chess Opening Wizard. I like both programs


It also imports flawlessly into Chess Assistant. It comes with Houdini loaded in as the default engine, but several more are available.

I've had no trouble importing purchased chess books from Modern Chess. They just PGN files, so you will need a program that imports PGN.

Everyman Chess has several electronic products, many of which come in multiple formats. Their Kindle and EPub files work very well to give you an electronic book which you can open on screen next to your preferred computer chess board. Their CBV files import perfectly into ChessBase. Their PGN files require some clean-up by the user - at least that has been my experience using Chess Opening Wizard or Chess Assistant.

I have both Marin and Mikhalevski works. The newer work by Marin has some improvements as one might expect.

Marin's work is an ebook available at Modern-Chess.com. It seems to read in perfectly in either ChessBase or Chess Opening Wizard. I like both programs.

Chess Opening Wizard is a position data-base and every recommendation and branching is visible at every move. There's your repertoire! Of course you can add in your own moves or games (PGN) that you choose. Stockfish 10 analysis is available.

ChessBase works too. You get a great view, game by game. That is ideal if you want the drama of a particular game, or if your mind files information by game. Deep Fritz analysis is available.

I think that the most problematic part of the Open Ruy López is the rook and bishop endgame where Black has the isolated e-pawn.

I think that I could hold this against someone my rating and higher, but an elite GM would probably try to torture anyone if they got that as White.

Having said that, if I were White (and played 1. e4), I would not choose that line to try to win.

You are absolutely right that Kaufman recommends the Breyer and the Marshall as his primary recommendations in the new edition.  He also has a chapter on the Moeller for Black. 

That said, in the White part of the book he says Lc0 puts the Open on par with the Marshall and that after analyzing with Lc0 he had a newfound respect for the Open.  He recommends a main line after 9 Nbd2 as the best chance for an advantage but given the limitations of a repertoire book he doesn't have space to look at all that many sidelines or analyze it in too much depth.

This looks fun.  The Dilworth and the Open more generally is easy enough to play at the club level.  LcO seems to like it too according to the new Larry Kaufman book. 


I thought that Kaufman recommended the Marshall and Breyer in his new book.
