I am a little more worried about 11...b4 at once. White has compensation after 12.Nce2 Bxe4 13.Ng3 Bb7 14.f4, but is it enough for two pawns?

At the moment it is clear as mud to me.


Yes, of course , i 've forgotten Qh5 a key move in the ussr. Now i became more clear and i have a good feeling!

If you are right, then White has a problem after 4...e6 5.Bc4 a6 6.Nf3 Ne7 7.Bg5 h6, as 8.Bh4 will be answered with d6 9.0-0 Nbc6 heading for a favourable transposition: 4...Nc6 5.Nf3 d6 6.Bc4 e6 7.0-0 Nge7 8.Bg5 a6 9.Qe2 h6 10.Bh4?! iso 10.Be3. Or can White take benefit from not having played Qe2 ? I am not convinced by the famous game Landa-Kasparov, Moscow 1988, bceause of  10.Qd2 g5 11.Bg3 Ng6 12.Rad1 e5 13.Nd5 Bg4 14.Be2 Bg7 15.Ne3 Bxf3 16.Bxf3 Nd4 and White's bishops do not impress me.


Interesting it seem you've right tought i'm not sure that whites are really in danger but those positions looks rather unclear

There are two other relevant games, albeit by transposition:

Tkaczyk,P - Jedrzejowski,M [B21]
corr 1996
1.e4 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3 e6 5.Nf3 a6 6.Bc4 b5 7.Bb3 Bb7 8.Qe2 Ne7 9.Bg5 h6 10.Be3 Ng6 11.0–0 Be7 12.Nd4 0–0 13.Rad1 Qc7 14.Qh5 b4 15.Nce2 Bxe4 16.Ng3 Bb7 17.f4 Nh4 18.f5 Nxg2 19.Bxh6 Qe5 20.Bxg7 Kxg7 21.f6+ Bxf6 22.Ngf5+ exf5 23.Nxf5+ Kg8 24.Qg6+ Kh8 25.Bxf7 Rxf7 26.Qxf7 Nh4 27.Rd3 Qc5+ 28.Re3 Nxf5 29.Qxf6+ Kh7 30.Qxf5+ Qxf5 31.Rxf5 Kg6 32.Rf2 a5 33.Rg3+ Kh5 34.Rf5+ Kh6 35.Rf6+ Kh5 36.Rb6 Ba6 37.Rbg6 Nc6 38.R3g5+ Kh4 39.Rg2 Kh5 40.R6g5+ Kh6 41.R5g3 Be2 42.Rxe2 1–0

Notes:
12...b4 worries me a bit; 13.Na4 Bxe4 14.Rad1 Qa5 15.f4 Nc6 (0-0 16.f5 is great for White) 16.f5 Nge5 17.fxe6 dxe6 18.Nxe6 fxe6 19.Bb6 only shows, that a5 is a bad square for the queen. Is 14...Qc7 better? 15.f4 Qb7 16.f5 Nh4 17.fxe6 fxe6 18.Bxe6 is another attacking line.
17...Nc6 18.Ndf5 Bf6 19.Nxh6+ gxh6 20.f5 Nge5 21.Ne4 and White has a dangerous attack.

Frankle,J (2250) - Serper,G (2555) [B21]
American op-37 (2), 2001
1.e4 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3 e6 5.Nf3 a6 6.Bc4 b5 7.Bb3 Bb7 8.Qe2 Ne7 9.Bg5 h6 10.Be3 Ng6 11.0–0 Be7 12.Rad1 0–0 13.Nd4 Qc7 14.a3 Nc6 15.Qh5 Nxd4 16.Bxd4 Rac8 17.Rd3 Bd6 18.Rfd1 Be5 19.Bxe5 Qxe5 20.Qxe5 Nxe5 21.Rd6 Bc6 22.R6d4 Rc7 23.a4 bxa4 24.Nxa4 Rb8 25.Bc2 Bxa4 26.Bxa4 Rxb2 27.f4 Ng4 28.h3 Ne3 29.R1d2 Rxd2 30.Rxd2 d5 31.Rd3 Rc4 32.exd5 Nxd5 33.Bb3 Rc3 34.Rxc3 Nxc3 35.Kf2 a5 36.Ke3 a4 37.Kd3 axb3 38.Kxc3 Kh7 39.Kxb3 Kg6 40.g4 h5 41.Kc4 hxg4 42.hxg4 e5 0–1

Which shows, that 14.a3 is a lame move.

1.e4 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3 e6 5.Bc4 a6 6.Nf3 Ne7 7.Bg5 b5 8.Bb3 h6 9.Be3 Bb7 10.O-O Ng6 11.Nd4 Be7 and the obvious plan is 12.Qh5 (winning a tempo and compared to the Serper game even two) b4 13.Nce2 Bxe4 14.Ng3 Bb7 15.f4 Nc6 16.Rad1 and 17.f5. I am a little more worried about 11...b4 at once. White has compensation after 12.Nce2 Bxe4 13.Ng3 Bb7 14.f4, but is it enough for two pawns?

In that Novak-Lanc game White has some other options.
12.Nd4 (iso 12.Nd2) Bxc3 13.bxc3 Bxe4 14.a4 bxa4 (Qc8 15.axb5 Qxc3? 16.Rfc1 +-) 15.Rxa4 Bb7 16.f4 0-0 17.f5 exf5 18.Nxf5 and all White pieces are ready for action.
12...Qf6 (iso Nc6) 13.a4 bxa4 14.Bxa4 Nf4 15.Qc4
14.a4 (iso 14.Rad1) bxa4 15.Rxa4 followed by 16.e5 or 16.f5.

At the moment it is clear as mud to me.

We'll see, if this name will stick. Personally I would prefer to use the analogy with the Open Sicilian (Scheveningen, Dragon), so it would be logical to name the ...Nge7 the Taimanov Defence. Only problem is that I don't know if GM Taimanov would approve.

10...Nbc6 11.a4 b4 12.Nd5 Na5 13.Nxb4 g5 14.Bg3 Qb6 is quite unclear.
According to my sources the result of the game was a draw and a glance at the final position convinces me, that this is the correct one.
17.Rd1 deserves a big questionmark - probably even two.

I still find 10.Be3 simplest. With ...b4 Black can grab a second pawn, but will lose the exchange. After 10...Nbc6 play will transpose to other variations.

Hello Mnb and all!

First of all i would like to propose a name for variations with Nge7 (before the developpement of the king's bishop).This variation was played as early as the fifties by players such as Suetin, Koblenz(koblencs)... then Petkevitch, Sakharov and more recently Yudasin and the King himself! (Landa-Kasparov 1988) so why not the USSR's variation!

Second  the USSR  Smiley with h6 is relatively unknown territory so it's not easy to find the right way.
At the time (1994)Burgess prefered h6 Bh4 and now Langrock recommand h6 Be3


In the game i just give some personnal ideas if you don't like it find another one!

The remark on 8.Qe2 Ne7 is an important one, as in regular ...Nge7 lines the queen usually does not go to e2. Black gets ...Bb7 for free: 8.Qe2 Ne7 9.Bg5 f6 10.Be3 Nc6! (not mentioned by Palkovi) 11.0-0 (what else?) and Black has transposed to the favourable line 4...Nc6 5.Nf3 e6 6.Bc4 a6 7.0-0 Nge7 8.Bg5 f6 9.Be3 b5 10.Bb3 Bb7 when 11.Qe2 is not such a good move, see Garcia Ramos-Barria Zuniga, Valencia 2003.
White has to play 8.0-0 iso 8.Qe2 and offer a second pawn. It makes me wonder though, if 8.0-0 Ne7!? is a good idea. There is a game Lochte-Knechtel, Bavaria 2002, which is not very helpful: 9.Bg5 (the usual reaction) h6 (f6!?) 10.Bh4 (but this is unual, in similar lines 10.Be3 is the approved move) b4?! (necessary? Why not d6 or Nbc6 ?) 11.Ne5 Nbc6? (g5 12.Qh5 Rh7 13.Nd5 is to be investigated, if this line ever becomes important) 12.Nc4 d5 13.exd5 (13.Nxd5!? is also strong) bxc3 14.dxc6 Qxd1 15.cxb7 Qxf1+ 16.Rxf1 Rb8 and White missed the mate, subsequently spoiled his advantage and had to adjust to a draw on the 56th move.

Later edit:
after a good night sleep I have come to the conclusion, that stereotypal play is best: 8.0-0 Ne7 (b4 9.Nd5!) 9.Bg5 h6/f6 10.Be3 as b4 11.Na4 Bxe4 12.Nb6 looks promising for White.

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

A quick sum up about the move order:
  1. e4 c5 2. d4 cxd4 3. c3 dxc3 4. Nf3 e6 5. Bc4 a6 6. Nxc3 b5 7. Bb3 Bb7 8.0-0! (8.Qe2 Nge7!? Langrock) d6 (8...b4 9.Nd5!) 9.Qe2 Nbd7 10.Bf4! Ngf6 (10...Be7 11.Rfd1) 11.Rad1 with compensation

Great analysis here guys! Dji's 10) Bf4 is definitely very dangerous for black.  Shocked

Some really great variations and analysis here, especially by Dji who first brought up 10.Bf4! and Rad1! instead of the "automatic" Rfd1. Nd5 really is deadly in many variations.

I wonder what SevenSpheres who started this thread thinks: Quote:
I would very much like to see an example of the Nd5 sac with Rooks piled on the d-line, I just can't get this variation out of my head.  I think a stark visual example of Black getting thrashed would be just the right tonic for my ailment!

    Sevenspheres is missing ,not connected since 27 may 2007. I hope he'll come back ! Uberdeker and others too.

Hope you slept well.  Wink Then the problem 18...f5 might disappear like snow in the sun: 19.Rc4 Qb8 20.Ba4+ Kf8 21.Ne5 Nf6 22.Rd1 and White must have enough for the piece.
I am confident, we have solved the a6/b5 problem.


Cool ! Cool

Probably 17.Qd2 is little better for white

You might be right indeed.

a)15...exd5 16.Bxd5 Bxd5 17.Rxd5 looks critical. Black has quite a few reasonable moves: Nf8; Qb7; Qc6. White may try 16.Rxd5 Nc5 17.e6 Qxf4  18.Rxc5

The problem is here 18...f5!? that why i 've a lot of time last night, I've tried  17.Rc1 too ( instead of 17.e6 ) maybe enough for a draw

Now i  try 13.a5 Qc7 14.Na4 Nf6 15.Nb6 but before i've to sleep!  lol
