King seems to give thorough coverage to the main moves 4Nc3 and 4e5. Do you know if he looks at 4Bxc6!? also?

King devotes an entire chapter to 4.Bxc6. (He also has separate chapters on 4.Nc3 and 4.e5). After 4.Bxc6, King's main line is 4...dxc6 5.d3 g6 6.h3 Bg7 7.Nc3 0-0 8.Be3 b6. Now he covers three variations: 9.0-0, 9.a4, and 9.Qd2. The queen move, which is by far the most common according the the Mega Database, prepares 0-0-0, resulting in a sharp position with the kings castled on opposite sides. King says Black's chances in this line are no worse than White's, adding that the computer supports this assessment.

GM Daniel King has a bit of coverage of the variation in Reply #8 in his recent book, King's Anti-Sicilians for Black.

GM Daniel King has at least two suggestions that I think will be interesting to me.

1.e4 c5 2c3 e6 that you mentioned, is something that I've considered before and it's nice to see that it being recommended. It looks like he gives good coverage.

1e5 c5 2Nf3 Nc6 3Bb5!? Nf6!? is something that I've recently looked at due to his recommendation. King seems to give thorough coverage to the main moves 4Nc3 and 4e5. Do you know if he looks at 4Bxc6!? also?

FreeRepublic - GM Daniel King has a bit of coverage of the variation in Reply #8 in his recent book, King's Anti-Sicilians for Black. It might be a bit surprising to see a book on Anti-Sicilians dealing with this position, but it comes about because King recommends meeting the Alapin Variation by transposing to the French Advance: 1e4 c5 2.c3 e6 3.d4 d5 4.e5 Nc6. He then goes for the Euwe Variation and answers 6.Be2 with the same line that you give in Reply #8:  5.Nf3 Bd7 6.Be2 Nge7 7.0-0 cxd4 8.cxd4 Nf5. Now after 9.Nc3, his recommendation is also 9...a6, which he describes as, "A useful move, taking away the b5-square from White's pieces. It's also a waiting move, watching to see how White commits." King mentions the ...Qb6-a7 idea as well in a possible continuation after 9...a6: 10.Bg5 Qb6 11.Na4 Qa7 12.Be3 Be7. He describes this line as "playable". This is apparently one of those positions where Stockfish and Lc0 exhibit a difference in evaluation, with the former giving White a slight edge, while the latter calls it equal. 

King actually prefers 10...Be7 instead of 10...Qb6, giving the following line: 11.Bxe7 Qxe7 12.Qd2 0-0. He concludes that "Chances are balanced".

I also checked The French Defense Revisited, another relatively recent book that recommends the Euwe Variation. In this case, there's no mention of 9...a6 or the ...Qb6-a7 maneuver since the authors prefer 9...Rc8.

I think the Euwe variation works well against 6a3. More challenging is 6Be2.
1. e4 e6 2. d4 d5 3. e5 c5 4. c3 Nc6 5. Nf3 Bd7 6. Be2 Nge7 7. O-O

Black can choose between:  7...Ng6, 7...Nf5, and 7...cxd. I'm leaning towards 7...cd4 8. cd4 Nf5. As Black has traded pawns, White can now play 9Nc3. 9Na3 is challenging also. After 9Nc3 a6!?, ChessPublishing states "Preparing queenside play. One unique idea is to play ...Qb6, and if Na4, ..Qa7 keeping pressure on d4."

15...Rf8 16. Rf8 Kf8, which the engine considers equal. Stockfish suggests 16Kg2 for White and, earlier, 15...0-0-0 for Black

More difficult for White 7...cxd4 8.cxd4 Qb6 9.Bc2 Nb4 10.oo Nxc2 11.Qxc2 Maybe not so great for White...no advantage.

Thanks for the interesting thread.

1. e4 e6 2. d4 d5 3. e5 c5 4. c3 Nc6 5. Nf3 Bd7 6. Be2 Nge7 

7Bd3 is an interesting idea. 7. Bd3 cd4 8.cd4
Now 8...Nf5 is perfectly natural, but justifies White's play, as described in the initial post.
But 8...Qb6!? is better.
Here, Stockfish suggests 9. Kf1!? with equal play. 

So, 7Bd3 is not bad, but not best.

I'd say that's an understatement, since it appears that Black has a useful extra tempo on a line (the "withdrawn" Milner-Barry with 8. Bc2) which is perhaps already slightly better for Black.


I agree

Thanks your replies..
After  7..Qb6 8.dxc5! and Black has no useful pressure on e5 pawn. 
More difficult for White 7...cxd4 8.cxd4 Qb6 9.Bc2 Nb4 10.oo Nxc2 11.Qxc2
Maybe not so great for White...no advantage.

I feel like an idiot.

7...cd4! should be the first choice for Black.  Fritz suggests giving the pawn up via 8.0-0, but still gives Black about 1/2 pawn advantage.  7.Bd3 really does throw the pawn away, and the N on e7 allows Black to play the gambit line more safely with an extra tempo.  I can't imagine that Black is worse here.  In fact, White will have to work extremely hard to save the game.

dom, what did you have in mind?

I agree with Chess_Addict on the importance of 7...Qb6.  However, I have read enough of dom's posts to know that you have probably already considered it.   

My guts tell me that 7.Be2-d3 may be an excellent blitz weapon but would not hold up to the scrutiny of a serious game between two players rated over 2500.  I just don't see the justification.  Black hasn't made any mistakes (unless Nge7 is actually wrong), and Qb6 has to be the main try for Black.

(btw, even the very old idea of 7...g6 may be playable after Be2-d3.  I don't like it much, but it has a point.)

I look forward to your response, dom!

Just an impression, haven't even set the position on the board therefore the chance of my suggestion being crap is even higher than usual, but 7...Qb6 seems a better Milner-Barry to me.

C02: Giving tempo in Euwe variation

I reached end of my reading of Sveshnikov's book about the Advance.
An interesting (new?) move is following one in Euwe variation:
1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Bd7 (Euwe variation ; Black prefer to wait for White choice. If 6.a3 then Black has system with 6...f6!? and if 6.Be2 then Black has systems with 6...Nge7/Nh6) 6.Be2 Nge7 (in the chosen system, Black can play Nf5 or Ng6!?) and now 7.Na3 or 7.oo are common, but I have not found one game on chessbase online database with....
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *

7.Bd3!?   Shocked
Losing one tempo, but White can recover the tempo, in transposition like: 7...cxd4 8.cxd4 Nf5 9.Bxf5 exf5 10.oo Be6 and small advantage to White
The idea behing losing tempo is to deprieve Black from the system with Ng6!? because of 7...Ng6 8.h4!  cxd4 9.cxd4 Nb4 10.Be2 Rc8 11.Nc3 Be7 12.a3 Nc6 13.Bd3 oo (13...Nxh4? 14.Nxh4 Bxh4 15.Qg4) 14.h5 Nh8 15.Qc2 g6 16.Qd2 g5 17.Nxg5 Bxg5 18.Qxg5+ Qxg5 19.Bxg5 Nxd4 20.Bh6. 
If you get one game or analysis for 7.Bd3!? I will be inberested with it  Smiley
