I have also recently looked at this line and I thought that 19.Ba5 looked like a nice improved version of 19.Be1. Anyway, at the end of what I quote above, I think that 24.Rc1 looks pretty nice for white to me. White seems to simply have a nice space advantage with attacking chances on the kingside (and c2-c4 is in reserve). I'm not sure that black is really fine in this line.

When I play the taimanov, I have to play against the Be2/Be3- system in nearly every other game. At move 18 every player moves 18. ... Nd7, but what about ... Ne4!? I analysed it, of course with the help of Fritz, and it seems playable. Any opinions? Use strg + C and strg + V to copy and paste the lines.

Hello MarinFan,
yes, I agree that maybe 11.Kb1 is more promising. But in my game I wanted to avoid this line.That is why I played 11.Qe1 also hopping to surprise my opponent but instead looks like I was surprised myself  Wink.
The game is still in progress, so I do not want to comment it. When we finish it I can share my thoughts.

Hello MilenPetrov,

A few weeks ago my coach showed me line 2) above, and also something against 16Qe2 and 16h3, so think it is good.
             At the moment, don't think 11Qe1 and the usual direct king-side attack is very promising for white, because black can bring this to a halt with f5 at some stage. So 11Kb1, discussed in another tread, trying to use black's queen-side pawn weakness's looks more dangerous.

Yes, you are right about 22Kh1! Sergei Soloviov pointed out this move to me about a year ago. If your idea proves good, it will be included in some future update of the Safest Sicilian with your authorship.

Hello,
first of all thanks to all for your efforts in this forum. A lot of interesting ideas appear here.
Now I want to share a small addiion to the Safest Sicilian book. Recently I am playing a corrspondence game in the following line in English Attack:
1.e4 c5 2.Nf3 e6 3.d4 cd4 4.Nd4 Nc6 5.Nc3 Qc7 6.Be3 a6 7.Qd2 Nf6 8.0-0-0 Bb4 9.f3 Ne5 10.Nb3 b5 11.Qe1 Be7 12.f4 Ng6 13.e5 Ng4 14.Bd2 Bd7 15.Bd3 Rc8!
Here Semkov and Delchev mention 16.Ne4?!, 16.Qe2 and 16.h3.
After 16.Ne4 0-0 17.Kb1 f5! 18.ef6 Nf6 19.Rf1 in the corrections of the book only 19...Bd5 is mentioned. Here are my findings:
1) 19....Nd5 20.g3 b4 21.h4 a5 22.h5 Nh8 23.Ng5 (23.Nd4 Qb6 24.Nf3Nf7=+) 23...Bg5 24.fg5 Rf1 25.Qf1 a4 26.Nd4 a3 unclear;
2) 19....Ne4!N 20.Be4 21.Qe4 Qc4 22.Qc4 bc4 23.Nd4 Bc5 24.Ne2 (24.Nf3) 24...d5 and Black is fine (even slightly beter).
I am interested to hear your opinion about these lines.
In fact in the game I choose 16.Qe2 and the game is still in progress. When we pass the opening phase I will share the game with you.
Best Regards
Milen Petrov

Hello,

Looks good as far as I could tell. At first thought white could get away with 19 f3 because if 19..Bc5+ 20Bd4 but black playing d5, causes some problems. (Sorry not proper variations, but at work and dont have sight of board).
                     In the other variation have not worked out difference with 22Kh1 instead of 22Kg2 yet.

Hi all,

during my holiday I reread the semkov/delchev book again and hopefully I found an interesting (and strong Wink ) novelty:
1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nc3
Qc7 6. Be2 Nf6 7. O-O a6 8. Be3 Bb4 9. Na4 Be7 10. Nxc6 bxc6 11. Nb6 Rb8 12.Nxc8 Qxc8 13. Bd4 c5 14. Be5 Rb6 15. b3 Nxe4 16. Bxg7 Rg8 17. Bb2 c4!
instead of Bf6 and Rd6; I can`t help but Rd6 looks strange to me;
17...Rd6 18. Bd3 c4 19. bxc4 Qc6 = according to S/D 20. g3 Ng5 21. f3 h5 22. Kh1!? [instead of Kg2] h4 23. gxh4 Nh3 24.Qe1 and it seems white can defend successfully and win the game.) With 17. ...c4 black sacrifies a pawn to activate his pieces for example:
18. Bxc4 Qc6 19. Qf3 Nd2 20. Qxc6 Rxc6 21. Bd3 Nxf1 22. Kxf1 f5 and black is slightly better.

Any opinions?

I will test the suggested lines in a CC tournament (WCCC semifinals). Out of the 6 games as black, 4 has started and all chose 1.e4. In one game we're already 10 moves into the english attack. Looking at previous games, I expect one opponent to play the Be2, 0-0, Kh1 line and another to play 2.c3, but then again, I'm not so good at predicting openings.

Maybe they all played 1.e4 because they saw my horrible play in the Najdorf.

Let's see what the other two players choose. Wouldn't it be strange if all play 1.e4?

Btw, I talked to an IM about the Taimanov. He called it 'The Najdorf for the lazy'.

Hello, I'm new here and I've just bought this book. I'd like to ask after 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nb5 d6 6. c4 Nf6 7. N1c3 a6 why can't White simply reply 8. Nd4? it seems that any attempts to take advantage of its position is hopeless e.g. 8... Qb6 9. Be3 Qxb2 10. Na4 Qa3 11. Bc1 Qb4+ 12. Bd2 Qa3 with repetition. So it seems that 8. Nd4 is a decent reply instead of Na3 as mentioned in the book.


8.Nd4 is playable – but apart from the aesthetic problem of moving the knight right back to where it came from – it is unlikely to yield white any advantage. White has wasted two tempi to make black play a potentially useful ...d6 and ...a6. 
After 8.Na3 (though this move is also not without drawbacks) white maintains some control over d5, making black's freeing ...d5 thrust more difficult to achieve. 
After 8.Nd4, In contrast, black can simply play ...Be7, ...0-0 and ...d5 fully equalizing, or if black is reluctant to simplify he can play ...Bd7, ...Nxd4 and ...Bc6 with reasonable prospects.

8.Nd4 is possible. It is mentioned in the books by Burgess and Rizzitano.

8...Be7 9.Be2 0-0 10.0-0 Bd7 11.Be3 Nxd4 12.Qxd4 Bc6 is the main line.

Hello,

I think you are right, would normally play BxN, to try and win d6 pawn, and/or get control of d5 for knights. F3 looks horrible, black would like to get Qb6, or maybe Bh4+ to provoke g3, to weaken f3,e4 in-directly.  Compared to lines where black plays immediate Be6, and pawn is on f2, black is considerably better, .i.e the 10...Be6 lines. Don't see an immediate wham-bam refutation of 11f3. though too.
                It turns out 11Be2 BxB 12 QxB d5 is not too great for white either, but this is non typical pointed line. Maybe didn't include 11f3 because it is clear not a great move at birth?, that and they have to draw line somewhere...

I've run into 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nb5 d6 6. Bf4 e5 7. Be3 Nf6 8. Bg5
a6 9. N5c3 Be7 10. Nd2 Bg4 11. f3
a couple of times. I assume there is a reason why into doesn't even merit a footnote in the book.
http://www.france-echecs.com/diagramme/imgboard.phpfen=rxxqkxxr%2Fxpxxbppp%2Fpxn...
Presumably it weakens the dark squares too much, particularly since Bxf6 is almost a given? Am I correct about that? Tactically the move is not immediately wrong, after all and white could really just play 11...Be6 12. Bxf6 Bxf6 13. Nc4...
