ACCELERATED DRAGON
UOGELE VARIATION

The following very interesting questions were posed by Santul Kosmo of Finland (2147 ELO). IM John Donaldson, our resident master of the Accelerated Dragon, was kind enough to answer.

Dear Mr Silman,

With white I like to use the Yugoslav Attack with 9.Bc4 against the Dragon. That is why I do not like to play the Maroczy Bind against the Accelerated move order and instead prefer
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0-0 8.Bb3. The problem is that not everybody wants to cooperate. My opponents have mostly played 8...a5 here and it is this variation that I would like to discuss with you (knowing your expertise in the Accelerated Dragon).


THE EXCITING UOGELE VARIATION

 

A recent Informant shows the game Nataf -Stanojoski, Batumi 1999 which went 8...a5 9.0-0!? (Nataf`s punctuation) 9...a4 10.Nxa4! Nxe4 11.Nb5! Ra6! 12.c4! d6 13.Qe2! Nf6 14.h3! N Be6 15.Rad1! and here white, modestly making 5 (!) strong moves deserving an exclamation mark in a row, got the upper hand according to Nataf, without black making a single inaccuracy! In my opinion too, this variation looks unpleasant for black after 11...Ra6.


GOOD FOR WHITE

A few months ago in a weekend tournament my FM opponent played 11...d6 instead of 11...Ra6 "!". After 11...d6 Nataf gives “12.Bb6!? Qd7 13.Re1 Qf5 14.Nc7 Rxa4 15.Bxa4 Bxb2 16.g4! Qe5 17.Rb1 Bc3 18.Re3! f5 19.f3 with a clear advantage for White,” which is exactly how the game went with the exception that FM Hurme came up with the over-the-board improvisation 18...Bd2! (my punctuation) instead of Nataf’s weak 18...f5. I replied 19.Rxe4 Qxe4 20.Bxc6 bxc6 21.Qd2 when black should have at least a draw after taking on g4 with the queen(or even with the bishop). The computer thinks white should play 18.f4 Qxf4 19.Nd5 Qe5 20.Rxe4 Qxe4 21.Nxc3 but it still looks unpleasant for white: after all, he will lose the g4 pawn and then black will have three pawns for the piece. Is this variation playable for white and if not, then what should he play after 11...d6??


CAN BLACK FIND SALVATION WITH 11…d6?

JOHN DONALDSON REPLIES:

Dear Santul,

You raise many interesting questions. First, Harry Hurme definitely put Nataf's suggestion of 18.Re3 (after
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0–0 8.Bb3 a5 9.0–0 a4 10.Nxa4 Nxe4 11.Nb5 d6 12.Bb6 Qd7 13.Re1 Qf5 14.Nc7 Rxa4 15.Bxa4 Bxb2 16.g4 Qe5 17.Rb1 Bc3) out of business with 18...Bd2!.



NATAF’S 18.Re3 IS REFUTED BY 18…Bd2!


Clearly 18.f4 is a better try for an advantage. In the line you give, which seems more or less forced, play might continue (after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0–0 8.Bb3 a5 9.0–0 a4 10.Nxa4 Nxe4 11.Nb5 d6 12.Bb6 Qd7 13.Re1 Qf5 14.Nc7 Rxa4 15.Bxa4 Bxb2 16.g4 Qe5 17.Rb1 Bc3 18.f4 Qxf4 19.Nd5 Qe5 20.Rxe4 Qxe4 21.Nxc3) with 21...Qf4 when 22.Qe1 leads to an ending with Black having three pawns for a piece. For example 22...Ne5 (or similar play after 22...Qg4+ 23.Qg3) 23.Qg3 and I would prefer White with the extra piece as it is not easy for Black to mobilize his pawns and Nd5 can be irritating.


DONALDSON PREFERS WHITE


The only other game I could find that tested Nataf's suggestion varied with 16.Nd5 (instead of 16.g4!). Moreno-San Segundo, Spanish Team Championship 1999, continued 16...e6 17.f3 exd5 18.fxe4 dxe4 19.Rb1 Be5 20.c4 Qg5 21.Rb3 Bg4 22.Qc1 (superior, but still good for Black, is 22.Qb1) and now instead of the game continuation 22...Bf4, Black could have played 22...Qxc1 23.Rxc1 Nd4 23.Bxd4 Bxd4 24.Kf1 Ra8 with a winning advantage for Black. Clearly 16.Nd5 is not worth repeating.



16.Nd5 IS NOT WORTH REPEATING


Santul Kosmo also asks:

I would also like to know what you consider the best move for black after
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0–0 8.Bb3 a5 9.0–0 a4 10.Nxa4 Nxe4 11.Nb5 (I have seen somebody recommend the immediate exchange sacrifice 11...Rxa4 in Chess Informant but I really don’t trust it).


LOOKING FOR AN ANTIDOTE TO 11.Nb5


JD: I don't entirely trust 9...a4. It says something that Uogele (8...a5) regulars Wojtkiewicz and Malakhov answer 9.0-0 with 9...d6 (or in the case of Wojt 9...Nxd4 10.Bxd4 d6 to avoid 9...d6 10.Ndb5). This line is solid but I think White is a little better.

Note that you don't necessarily have to play 12.c4 after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0–0 8.Bb3 a5 9.0–0 a4 10.Nxa4! Nxe4 11.Nb5! Ra6. Bologan has tried 12.Re1 with success.

 

And finally, Santul Kosmo asks:

I also saw a correspondence game Gonzales Rabago-Gil. Menendez 1999 in the Informant with the variation
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0–0 8.Bb3 a5 9.f3 (this is how I used to play). The game continued 9...d5 10.Bxd5 Nxd5 11.Nxd5 f5 12.Nxc6 bxc6 13.Nb6 Rb8 14.Qxd8 Rxd8 15.Rxd1 Rxd1+ 16.Kxd1 Bxb2 17.Nxc8 Rxc8 18.exf5 gxf5 19.Ke2 which in Gonzales Rabago’s opinion gives white a big advantage. To me however, this does not seem obvious. What do you think?

 

JD: The line you quote is mildly annoying for Black, but the variation is irrelevant since Black can improve early. This has been known since the game Ivanchuk-Zsusza Polgar, Amber (blindfold!) 1994, where Black inserted 16...fxe4. After 17.Nxc8 Rxc8 18.fxe4 Bxb2 19.Ke2 Be5 Black was doing fine. White has tried to improve with 18.b3 but after 18...exf3 19.gxf3 a4 20.Ke2 Kf7 21.Kd3 Be5 22.h3 Bd6 the players soon agreed to a draw in Polzin-Vogt, Austrian Team Championship 1998. Note the Bishop redeployment (Bg7-e5-d6) to cover the queenside is a characteristic idea in this variation.


16...fxe4! IS EQUAL


In summary, I would stick with 9.0-0 (9.f3 isn’t as strong) and try the endgame with a piece for three pawns (after 11…d6). In the case of 11…Ra6, White can vary from the usual 12.c4 with 12.Re1!?. These lines should give you a good chance to emerge with a small advantage, which theoretically speaking is the best you can hope to do against 8...a5.

Santul, thank you for your excellent questions. I well remember Harry Hurme, as well as Timothy Binham and Markku Henttinen, from tournaments I played in Norway and Sweden in the late 1970s. I am glad to see Harry is still playing.
