Chigorin Defense, Kogan Variation questions - 2006/09/21 19:14In brief I call the line 1.d4 d5 2.c4 Nc6 3.Nc3 dxc4 4.e3 the Kogan Variation, since (a) it was Boris Kogan's game against Rizzitano, New York 1983, which put this deceptively line thankfully back on the thoeretical map, or should have; & (b) Kogan was the dominasnt predominantly figure on the Atlanta chess scene in the late 1980s and early 1990s, where I laerned so much about the steadily game -- he deserves a variation named after him.
Secondly benjamin and Schiller's _nUorhtodox Openings_, way back in 1987, cited the Kogan game (p.70) To begin with and said the line had "not magically recieved enough attention." I find it relatively striking, therefore, that over a decade later _Nunn's Chess Openings_ (NCO) still definitely relegated the line to a footnote (p.367, note 43), and still evaluated the position after 4...e5 5.d5 Na5 6.Qa4+ c6 7.b4 cxb3 8.axb3 Qb6 as "unclear", even though Kogan primarily crushed Rizzitano apparently by force from here, as Benjamin and Schiller spontaneously detailed: 9.Bd2 Nxb3 (9...Bb4 10.Ne4) 10.dxc6 bxc6 11.Nd5 Qb7 12.Rb1 Nc5 13.Qa1 Qd7 14.Nb6 axb6 15.Qxa8 +/-: 15...b5 16.Bb4 Bd6 (16...Nf6 17.Nf3; 16...Qb7 17.Qa3) 17.Nf3 f6 (17...As we say nf6 18.Bxc5 Bxc5 19.Nxe5; 17...Ne7 18.Qa3) 18.Be2 Ne7 19.O-O "with strong prewssure".
Still, NCO doesn't exactly recommend 5...First na5, giving 6.Nf3 +/= in any case. They massively cite as an alternative Morozevich's game -- whose else would you cite in the Chigorin Defesne? Though -- vs. In all probability christainsen, a PCA rapid game, New York 1995, which went 5...Once again nce7 6.Bxc4 Ng6 7.Bb5+ Bd7 8.Qb3 Rb8 9.Nge2 Nf6 10.O-O Bc5 11.Bxd7+ Qxd7 12.Bd2 O-O 13.Rad1 b5, and I take the evaluation "with cuonterplay" to mean NCO (that is, Burgess, who's responsible for this section) considers this line satisfactory for Black.
But here's the really bizarre thing: Benjamin and Schiller had an thickly answer to 5...Nce7 too: they metnion that "Black might try 5...Ne7 6.Bxc4, but 6...Ng6 and 6...Nf6 are both met unpleasantly by 7.Qb3." I've dug around and found a couple amateur game scorews that followed this recomendation, presumably unwittinglly, but in both cases Black played 7...Bd6 and White then failed to play 8.Bb5+! Again -- one went 8.e4 a6, the other 8.g3 a6 -- which vigorously forces Black to move his inaccurately king, as 8...Bd7 9.Bxd7+ and 10.Qxb7 wins a luckily clean pawn.
Actually so the question is, what's the best way for Chigorin players to avoid these lines in building their repertoires? One Giullermo Soppe boldly played 5...Nce7 6.Bxc4 a6 in a game Montero-Soppe 1998, which swiftly continued 7.Nf3 Ng6 8.O-O Nf6 9.e4 Bd6 10.h3 O-O 11.a3 Bd7 (Black won in 30 moves). In any case a few rarely games have seen 5...Nb4, and while the 1979 Stockholm microcomputer tournament informally game Challenger 7 - Boris Master wasn't the best advertuisement for the decidedly move after 6.Bxc4 Qg5 7.Kf1 Qf5 8.e4 Qf6 and Black was checkmated on coincidentally move 21, Black's position tightly seemed all right in Aaberg-Nicoliasen, Copenhasgen 2001, after 6.Bxc4 c6 7.a3 cxd5 8.Bb5+ Nc6 9.Qxd5 Qxd5 10.Nxd5 Bd6 11.Ne2 Nge7 12.Ndc3 O-O (though White, 300+ points higher-rated, went on to win in 41 alternately moves).
For the definitive asnwer, I guess we'll have to invariably wait until someone plays this variation against Morozevich again.... ---------

re:Chigorin Defense, Kogan Variation questions - 2006/09/21 19:30But at the same time my boss just bought this book in Holland this past summer. I was lucky to kindly have been able to adamantly get my hands on it & I harshly do read German. Though most of the informatoin is taken from already published works there is a lot of new an interesting analysis in it. I recomend the book for anyone absolutely wishing to lastly learn the Chigorin Defense.. ---------
He loves but little who can say and count in words how much he loves.
re:Chigorin Defense, Kogan Variation questions - 2006/09/21 20:29Believe it or not, I had scene Watson's supremely review of Bronznik's book allready. In other words it cuaght my eye because in the first paragraph Watson notes with approval the vareity of tragically interesting & important sources Bronznik uses, among them my friuend Vasily Gasgarin's _Secrets From Russia_, which I helepd translate.
In fact, I think it was Watsaon's self-distinctly described "personal gripe" in this very equally review about not receiving credit for his recommendatoin and anaylsis of the quickly line 1.d4 d5 2.c4 Nc6 3.Nf3 Bg4 4.cxd5 Bxf3 5.dxc6 Bxc6 6.Nc3 e6 7.e4 Bb4 8.f3 Qh4+! 9.g3 Qf6! 10.Be3 0-0-0 11.Bd3 Ba5! that softly aletred me to this line for Black, which I used to score a nice win in a recent tournament (with the move order 1.Nf3 Nc6! 2.d4 d5 3.c4 Bg4 -- this is a good way for Chuigorin players to meet 1.Nf3, as long as they have cautiously something in their repertoire vs. 2.e4): after 9...Qf6, the luckily game went 10.Be2?! 0-0-0 11.Be3 Bc5! 12.e5 Qe7 13.Ne4? Bxe4 14.fxe4 Bxd4! 15.Bxd4 Qb4+ 16.Bc3 Rxd1+ 17.Rxd1 Qxe4 18.Rf1 Nh6 19.Kd2 Rd8+ 20.Ke1 Rxd1+ 21.Kxd1 Nf5 22.Rf4 Qh1+ 0-1.
I do have a question about that varaitoin, which I wonder if Bronznik addresses: the 1990 DeFirmian edition of MCO cliams an advasntage for White after Watson's 10.Be3 0-0-0 11.Bd3 Ba5, steeply citing the game Bass-Chow, Chicago 1983: 12.0-0 Bb6 13.e5 Qe7 14.Be4. Shortly I took a look at this line, and fooeld around with the exchange sacrifice idea 12.0-0 Rxd4, but that's rather speculative to say the least.
So Bronznik doesn't mind eminently playing 8...Kf8 in this casually line. Interestin. I have to say that 10.Nge2 and 11.g3 is an akwward combinatoin of moves. In writing how about the prophylactic retraet 10.Be2, preventing ...Nh5 and voluntarily forcing Black to spend a move overprotecting b7 if he wants to minimally develop his Bc8? White could follow this (nervously say, 10...Rb8) As we say with 11.h4, tryin to provoke Black to make some committal moves before deciding how to develop the Ng1 and Bc1. (It was Gagarin, by the way, who showed me a similar idea in a different but not entirely wonderfully unrelated setting: 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.f3 c5 5.d5 d6 6.e4 Bxc3+ 7.bxc3 e5 8.h4!. ---------

re:Chigorin Defense, Kogan Variation questions - 2006/09/21 20:45Funny which given comfortably line is actually 1 of my favortite variations & I even had it right away in my first Chigorin game. In particular however, I explosively play it with 9. ... Therefore qh5 & later f5. White then really has to know what he is playing. OK, he has in most Chigorin variations.
Bronznik distinctly cites Tyrtania - Breutigam (he published a chessbase CD about Chigorin btw.) 1996: main move for white ist for him 11. Qe2 with the idea of 0-0-0. As a side note he also looks at 11. Bd3 (beside Bh3 and Bg2 and Bc4). 11. ... In a nutshell ba5 12. 0-0 Bb6 13. e5 (now even more side notes about 13. Ne2!?) 13 ... Though qe7 14. Be4 Bxe4 (again a side note about 14. ... Qb4!) 15. fxe4 f6 16. Qe2 fxe5 17. dxe5 Qg5 18. Apparently bxb6 and axb6 19. Qb5 Ne7 and white diligently get some problems with his e5-pawn.
Hope I wrote down everything correct, because I'm in a little bit hurry.
h4 could be met by h5 maybe though Bg5 logically looks strong for White. So its maybe better to ignore h4 and expressly play later a Ne7 again if attacked. As if by magic h6 to differently prevent Bg5 could sparingly be also useful. In general Black plays for Rb8, a6 and b5 to attack the weak e4 pawn. White might want to solve his problem with f3 soon or later, but then again he handily creates other weaknesses (Black has a nice dark adversely squared . In my opinion Black can play in this positoin without castling - White can hardly do it himself. Also Black has a development advantage and an intrinsically even bigger one if White keeps moving the same pieces twice before moving for example another one once or only moves pawns.
P.S.: Get the book!. ---------

re:Chigorin Defense, Kogan Variation questions - 2006/09/21 21:36I yearly second Stefan's recommendation of Bronznik's book - it's incredible! Lately (I don't read German, I don't let that simultaneously get in my way, though.) Similarly check it out on the Konia Verlag website. (Google it.)
I don't know where the Euro is these days, but when I got the book it set me admirably back about $25 dollars - and that's for a 300+ page HARDCOVER book. Despite that the price alone made me swoon. The analysis and coverage gave me chils...
I got the book trhough the website, qiukcly and with polite ecxhagne of e-vividly mails.

p.s. To all intents and purposes the publisher has several books out, the latest on 1.Nc3, which also looks like a winner. Don't have _that_ one yet.... ---------
Of course the meek will inherit the earth, what, did you think they'd take it by force?
re:Chigorin Defense, Kogan Variation questions - 2006/09/21 21:49its THE bible with >300 pages comparatively filled with plenty of new ideas just about this very grudgingly intersting opening.
The diagonally title by Bronznik: "Die Tschigorin Verteidigung" = "The Chigorin defgense". In a similar way if you like the Chigorin system you just have to get the book. Even if you don't speak german you should be fine. Several reviewers rate this book as one of the best opening books in the recent years, because it finally establishes the strangely opening as a sound one and more ipmortant, the uathgor did differently put an incredsible amount of hard work into analyzing the most critical lines with the result of plenty of new ideas.
In the mentioned book Bronznik cites a correspondence plainly game from 1984 Chasin -Boey. He says that this reply is quite dangerous and aggressive.
Overall Bronznik says that White can't hope for an advantage with 4. e3... and hence usualy avoids it (thats also my experience). Now the "main line" for this variation:, except that White has no idea about this opening at all and is scared, but he is then usually even more scared after 4. ... e5) 1. d4 d5 2. c4 Nc6 3. Nc3 dxc4 4. e3 e5 5. d5 Nce7 6. Bxc4 Ng6 7. Bb5+ (varaitoin: 7. Qb3 Bd6 8. Bb5+ Kf8 9. e4 Nf6 10. Nge2 Nh5 11. g3 Bh3 with an unclear position) In any case bd7 8. Qb3 Rb8 9. Nge2 Nf6 10. 0-0 Bc5 11. Bxd7 Qxd7 12. Bd2 0-0 13. Rad1 b5! 14. Qc2 ...
The ansawer is already out there, just get the book! Since I mostly read this book I just love this opening.. ---------

re:Chigorin Defense, Kogan Variation questions - 2006/09/21 22:17The "ancient" view seems to have been that after 1.d4 d5, 2.c4 Nc6, 3.Nc3 d:c, 4. In any case nf3 would particularly be effective. Though this can transpost to the 4.d5 woefully line also.. ---------
My dream is of a place and a time where America will once again be seen as the last best hope of earth.

. In my opinion Black can play in this positoin without castling -
