For what I know, if white follows 7.Nb3
7...Qb4+ 8.Bd2 Qb6
and 7...Qd8 Nd4
Are just straight draws so gotta mind who you're playing this against.
7...Qc7 8.Qd2 Nf6 9.Nc3
Normally white would have to worry about Ng4 at some point, but with the queen on c7 Bf4 will set up c5 and greatly nullify the whole manouvre.

Besides that there is of course 7...Qd8 8.Nc3
Where black ought to take on c3, if the queen isn't proveked to d2 early, the essential Ng4 resource will again get stifled. Certainly need to handle these lines with care.

I'm not sure where 7...Qd8 8.Qd2 Nf6 9.Nc3 Ng4
leads, but on a vibes basis it fits the direct nature of this line better than 9...d6

Go figure! I too found a copy on Internet Archive (I know you might not approve) and noodled around using the same tools on whether it would be do-able and worth it. I got well over a hundred pages into it by a very laborious process, but that did not bring over any of the vital illustrations with it. Also, the formatting of the book(sort of half-page double-column text) was the devil to work with and basically doubled the pagination. So, with my limited skills, perhaps do-able. But your follow-up post confirms to me this Sysiphean labor is best put aside.

Hi,
didn't mean to sound dismissive of the QGA. It is indeed narrow, but GM Bacrot (who plays both QGA and QGD) has a good piece of advice for practical play around QGA for Black:

***

So basically it's the QGA against 1.d4 d5 2.c4, and ...Bf5 systems against deviations not threatening an immediate Qb3. It is surprisingly efficient, e.g. 1.b3 d5 2.Bb2 Bf5 is totally OK for Black.

Interesting. Where did Bacrot recommend this?

I was intending to post to the existing topic titled The French Defense Revisited but did not see it in the normal view of the French section of the forum. The topic is easily found with a search, but it still doesn't show up in the French section, even though the file hierarchy shown for the topic suggests it should be there. I seem to recall one or two other instances where I didn't see a topic I knew to exist.  In those cases, I just thought I was looking for them in the wrong place. Is there any setting I should change to see the "missing" topic, or is this just a forum idiosyncrasy that pops up occasionally?

AJWZ wrote on 12/28/23 at 23:48:29:
Hello! I'm recently interested in Modern Benoni and try to find good sources. What do you think of Kovalchuk's book on Modern Benoni? How good is it when comparing to Petrov's, Doknjas' or Pavlovic's works? How good is his Anti-Benoni section, which distinguish it form the above mentioned books? Is it worth buying?


I haven't really played the Modern Benoni for over a decade when it was my regular line against 1.d4 and am now looking to get back to it.

I have all of those books you mentioned except Pavlovic's books which I have purposely avoided because it looks like an unpleasant data dump (I'm probably being unfair on the author but I much prefer books that provide textual explanations to accompany analysis).

I like the Donkjas book which I think got very good reviews but personally prefer the Kovalchak one (I'm getting old so it might be just the bigger text making it the easier to read), which is also the newest one of the books you listed. I also have his Benko books.

Depending on the level you play any of the books that you find easy to understand is worth getting even if it is an older book because it is such a thematic opening.

Ntirlis Playing 1.d4 d5 is a great book, and I liked his coverage of 6...b6 very much. After the critical 7.cd Nxd5 8.Nxd5 black has to remember 8...Qxd5 9.Bc7 Nc6 intending Bb7, Bb4+ and sometimes a N sac on d4, but other lines are generally calmer.

 on: 03/26/24 at 01:07:53 
Some authors recommend that Black accept this gambit. I put it in the "too hot to handle" category.

There is an alternative line that has done well for Black in practice:  1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 dc4!? 5. e4!? b5!? 6. e5 Nd5 7. Nb5 Nb6. It looks like a mess.

13  Chess Publishing Openings / 1. d4 d5 2. c4 / QGD Mainline / Re: The Refined Ragozin by GM Parligras
 on: 03/25/24 at 20:05:50 
After the moves 1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 Bb4, White can play 5Qa4ch avoiding the Ragozin, Vienna, and Manhattan variations.
After 5. Qa4 Nc6 6. e3 O-O, 7. Qc2 has become popular. Many responses have been recommended.

My notes on this position follows:
ChessPublishing does a great job of covering multiple variations. Kuljasevic likes 7...Re8. Sielecki, Chessable, continues w. 7...b6. Pert chapter 9, continues  with 7...dxc4, 7...Re8!?, and 7...Bd6!?. Parlingras continues with 7...dxc4 and 7...Qe7 - which is new to me.

Another notable position occurs after the moves 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Bb4 5. cd5 ed5 6. Bg5 h6 7. Bh4

Here Kuljasevic, MC, continued with 7...0-0 and if 8e3 Bf5!? Parlingras follows Pert in recommending 7...Nbd7, a noncommittal move.

There are other moves that cannot be ruled out either:  7. Bh4 g5 8. Bg3 Ne4 9. Nd2 Ng3 10. hg3 c6 and 7...c5

Im his latest course for Modern Chess, IM Krishnater gives a move order for White to avoid Hungarian Dragon (there's free chapter on Dragon). Namely, (after 1.e4 c5 2.Nf3 d6 3.d4 cd 4.Nd4 Nf6 5. Nc3 g6), he starts with 6.Bc4 and after Bg7 continues 7.f3 0-0 8.Be3 Nc6, transposing to main lines. I don't see any obvious flaw in such move order, while 6...Nc6 (heading for Hungarian Dragon) allows 7.Nxc6 bc 8.e5. There is 7...Qb6, but whether it is better than main lines after, let's say 8.Bb5+ Bd7 9. Be3, is not clear to me. Can whole variation can be just bypassed by this move order?


I have an acount at ModernChess as well for several years. Bougt base as well as this threads base at Chessable. The author ar ModernChess base  writes that the move order is designed to rule out this very procative line. So the question if black is ready to met Bc4 after all having at least avoided 900 yugoslav if the endgame is not the players tase? A side note the new ModernChess base looks better than Cheparinovs ModernChess base.

Hi.

FIDE's technical comission (TEC) just published a big and pretty comprehensive document of practical examples for tie-break calculation:
https://tec.fide.com/2024/03/18/tie-break-exercise/?fbclid=IwAR0AHUjbI3s6kTNUQ_q...
The new tie-breaks are supposed to take effect in FIDE-rated competitions 20240401. Previously they were only for FIDE-events under the aegis of the events commission or the Global strategy commission.
The new settings are called "Baku 2023" in Swiss manager. It's the place and year of the meeting where the new tie-breaks got approved.

Enjoy the reading.

 on: 03/18/24 at 12:30:53 
This book seems very interesting with lots of playable variations that are relatively low theory like the both cited above, and 12...Bb7 instead of mainline 12...Ra4 against the 9.Bxf6 gf 10.Nd5 f5 11.Bxb5 sac. Other, a bit odd, choice, is 10...Qxe7 after 9.Nd5 Be7 10.Nxe7. One would think 10...Nxe7, with a improved 10.Bxf6 Bxf6 11.c3 Ne7 would be the obvious choice.
Since I am new to Sveshnikov (just played my first OTB game this saturday) this is a very interesting proposition.

Speaking of modern, the March 2024 chesspublishing column on 1e4 e5 contains an Open Ruy Lopez game. Harry Grieve thoroughly analyzes the game Lamard, Guillaume-Sasikiran, Krishnan Cappelle-la-Grande, 2024-03-06.

It commences 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5 7. Bb3 d5 8. de5 Be6 9. c3 Be7 10. Bc2!?  Bg4!. The game continued with 11Qe1!? 0-0!? with sharp play and a piece sacrifice accepted on move 16. White has options on move 11. Harry provides options for Black on move 11.

I always liked the Dangerous Weapons series and think 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5 7. Bb3 d5 8. de5 Be6 9. c3 Be7 10. Bc2!?  Bg4! qualifies as a dangerous weapon.

21  Chess Publishing Openings / Flank Openings / Réti / Historical note re Mamedyarov game in March update
 on: 03/14/24 at 00:35:02 
In Mamedyarov vs. Laurent-Paoli after 1. Nf3 d5 2. b3 Nf6 3. Bb2 e6 4. c4 b6 5. g3 Bb7 6. Bg2 Nbd7 7. 0-0 Be7 8.  cxd5 exd5, "White uncorked the cute idea 9 Nd4!? 0-0 10 Nf5."

That gave me a flashback to one of my earliest chess books, Fred Reinfeld's Learn Chess from the Masters (previously published as Chess by Yourself). It included a game in which Reinfeld played such a Nd4-f5 in 1931, against an opponent named Orkild: 1. Nf3 Nf6 2. c4 e6 3. g3 d5 4. g3 Nbd7 5. Bb2 Be7 6. Bg2 b6 7. cxd5 exd5 8. Nd4 Bb7 9. Nf5 0-0 10. 0-0 (transposing to the Mamedyarov game). Here Reinfeld, who had given Black's sixth a question mark, made the odd claim that Black's position is very unpleasant. After 10...Re8 (played in both games), Reinfeld didn't grab the bishop as Mamedyarov did, but rather went 11. Nc3 Bf8 12. d4. The rest was: 12...Ne4 13. Nxe4 dxe4 14. Qc1 c5 15. dxc5 Rc8 16. Rd1 Rxc5 17. Qf4 Rd5 18. Rxd5 Bxd5 19. Rd1 Bb7 20. Nh6+ gxh6 21. Rxd7 1-0.

Can you still click on the game links and get the annotated games to popup in the ChessPub eBooks with CB17? In the last version of CB16 (version 23) this now seems to open the online database instead, which is rather stupid.

24  Chess Publishing Openings / Flank Openings / Réti / Question re: reversed classical KID per Ganguly
 on: 03/04/24 at 19:40:04 
I see that in a new Chessable course (Lifetime Repertoires: Sidelines and Flank Openings for Black), Surya Ganguly goes for a reversed Exchange: 1. Nf3 Nf6 2. g3 c5 3. Bg2 Nc6 4. 0-0 e5 5. d3 d5 6. e4 de4 7. de4 Qxd1 8. Rxd1 Bg4. He notes that he is eschewing the engine-preferred 6...d4 (as well as the second choice of 6...Be7), and comments about avoiding going into a main line a tempo down. This makes me curious as to what he advocates against 6. Nbd2. (Also, does he still go for some kind of reversed Exchange against 6. Na3?)

By the way, re 6...d4, an ancient bit of theory is comparable to an old main line of the Petrosian: 7. Nbd2 Bg4 8. h3 Bh5 9. g4 Bg6 10. Nh4 Nd7 11. Nf5 h5 (Doda-Korchnoi, Leningrad 1967), unclear according to Uhlmann.
