I'd appreciate having this book in electronic form. I may break down and buy it in hard copy anyway.

Modern-Chess.com also has an excellent e-book by IM Kanmazalp. I'd not previously heard of him, but can vouch for the quality of his work.

Regardless of the source, we are talking about:
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. Bg5! e6 7. Qd2 a6 8. O-O-O Bd7

The original main-line continues with 9.f4 b5. With ...b5!? we get to the line referred to by Yermolinsky and others the Kozul suicide line. Unfortunately for black, white came up with a second main line starting with 9f3. Both moves have done well for white. 9f4!? is tactical and sharp, lending itself to concrete analysis. 9f3!? is more amorphous with different ideas an many transpositions. It's harder to get a handle on 9f3.

After 9f3, IM Kanmazalp analyzes the old main line with 9...Be7 and the newer 9...Nxd4. Take your pick. I imagine I will take a few looks at both lines. I was already familiar and comfortable with 9f4, but I can tell you that Kanmazalp has a lot to add.

After 9...Nxd4 10Qxd4, Kanmazalp continues with 10...Be7. While I will doubtless go through this, I first looked at a suggestion of Stockfish, namely 10...Bc6. For example 11. h4 h6 12. Be3 d5!? 13.exd5 Nxd5 14. Nxd5 Qxd5 15. Qxd5 Bxd5.

It's hard to believe that white has anything here, though either player might enjoy playing this endgame (or not).

My approach is first see if there is anything that I like vs. 9f3. If so, then I can look forward to learning more about the highly combative 9f4.

To me if I understand, the Kozul "Suicide" Variation is the best variation for Black. I really do not like putting the bitchop on e7 or any of those related old lines. Last time I looked at those variations, Black suffer a lot positionally, except without the sharp counterplay of the Kozul. Does anyone even analyse those lines as much  ¿ I am not referring to White, I mean Black players who play against the Richter-Rauzer

The entire Classical is usually not played as much as the Najdorf or Taimanow at high level, except occassionally. And even in those occassions, it seems that most choose the Kozul anyway. I find the entire variation to be fun and sharp. If you are in the mood to get into one of those situations where if you or your opponent make a slip you win.

I had contacted Thinkers few months ago and I was told that this book available the 21th of this month.

Recently Modern Chess have new database on the Richter-Rauzer as well:

Maybe the Classical is becoming more popular ¿ 

Hi.

Not me.
If there is anything that is especially puzzling or interesting I would be quite willing to take a look though.

Have a nice day.

I do not own the Negi, but I got to look at it for a day or so. I remember that his mainline is the Kb1-f5 variation, where Kozul and Jankovic recommend Qc5. So, the moves after the initial Kozul position are
11. Kb1 Qb6 12. Nxc6 Bxc6 13. f5
I think Negis mainline is 13. ... b4 now, where he also adresses Marins proposal. I didn't properly checked it, but a friend of mine did and he believes that Negis analysis on that can be improved fairly easily. Food for thought?

But my interest lies in the comparison to Kozul and indeed, they meet in a sideline after

13. ... Qc5 14. Bd3 h5 15. fe fe 16. Rhf1 (Kozul looked at e5!? mainly) Bg7 and now Negi proposes 17. Ne2 which only got an "unclear" sign by K&J. He then follows a correspondence game but I think there were not much else analysis. For me, even without checking this does seem like a proper way for White and Black. Negi can claim a typical advantage, while Kozul and Jankovic seem to be happy to play Black in another typical, unclear Kozul variation. So not a big upset here!

I hope that this answered your question

It's the Kozul. Naturally, it turns the chessboard upside down.

The funny thing is that my students nearly always notice this before I do during an analysis, since I almost never look at the numbers and letters.

Thanks CarriedbyGg!

Sorry for the long waiting. Kozul proposes 9. ... h6 10. Be3 b5.
