| WannaBe: <RonB52734> Just read your profile, a lot of the names you mentioned doesn't have a bio on their page. Would you care to add a few words to their page(s)? :-) Or ask the players themselves to join us and chip in a few words. Do they all in your town?! And what town is that, if I may ask? |
 |
Aug-08-05
 |
| RonB52734: Yes, they're all here (Stanislav G Kriventsov may not live here -- I'm not sure. But he plays here frequently). And "here," of course, is Pittsburgh. www.pittsburghcc.org With the exception of Stanislav G Kriventsov and Alexander Shabalov (sometimes called "the Pittsburgh pounder"), the fellows I mentioned in my bio are strong local players who do get the chance to play in some top-level competitions and so they have turned up in the cg.com database (but, sadly, generally with losses against great competitors). |

| jamesmaskell: Do you know the 10 year olds name? Im curious... |

|
| RonB52734: Well of course I know the 10 year old's name! He sat across the board from me in a Tuesday night tournament and took my lunch money! (Quite a young gentleman, actually, and well known in local chess circles). On principle, I won't post a 10-year old's name on the Internet, although, to paraphrase Robert Novak, his name can be determined from the USCF's website. |

| WannaBe: <RonB52734: ... took my lunch money!...> Ouch... I'd take him back to the dark and deserted alley and get the lunch money back! And then take his! :-)) |

| TheAlchemist: In the variation <10.Bd3 h6 11.Bh4 g5!? 12.fxg5 Ne5> I have come up with a dubious Queen sacrifice <13.gxf6?! Nxf3 14.gxf3>, which is (most likely) fundamentally unsound, but can be very tricky. I have analyzed it with my computer a bit, but I would like to hear comments from a human perspective. Anyone? Thank you. P.S.: Here is one game, with the usual 13.Qe2: Gulko vs Savon, 1973 |

[Site "Moscow"]

Of course, he was only 11 at the time. |

| TheAlchemist: <azaris> Thanks for the find! After looking at it more objectively, I realize it's unsound, but still, OTB anything can happen :-) I still favor 14. gxf3 and 15.Rhg1, though. But Black just has to play Bc6 on time, to prevent Nd5 and h6-h5 to develop the Bishop on h6. If he doesn't, then trouble might arrive. |

| TheAlchemist: <tpstar> Thanks! I haven't done such deep analysis myself, so yours is much appreciated. If that buries my line objectively, it does not, however, bury my intentions of playing it, if it ever arises in a game. So far, the furthest I got was until 10.Bd3, then my opponent played 10...b5. It was a rapid game (my opponent's rapid rating was 400 points higher), I played very well and outplayed her in a Rook ending, but lost on time. |

|
| tpstar: <TheAlchemist> I was surprised it wasn't more negative (so to speak) since White gets 2N&P versus Q. I'm guessing White's space advantage on the Kingside gives compensation, plus the advanced Pf6, also Black's lack of development. The above shows one huge drawback of computer analysis = no human would play 15 ... b6 and then play 16 ... b5, therefore you could omit #2 altogether. I do think 14 ... Bf8 is better than 14 ... Bd8 by defending the g7 entry point (especially since you planned 15. Rhg1), but also allowing ... 0-0-0 if desired. I'd be concerned that Black's Queenside Pawn storm would trump any attack you might get against Black's King, and the Queen is a potent attacker over there. Good luck with it. =) |

| BaranDuin: Lately I was able to do an interesting piece sacrifice after 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 6 Bg5 e6
7 f4 Be7 8 Qf3 Qc7 9 0-0-0 Nbd7 10.g4 b5 11.Bxf6 Nxf6 12.g5 Nd7 13.f5 Pc5 (The first new move for me, I was prepared for Bxg5+) 14. h4 (Probably f6 was better) b4 
click for larger view(Pushing away the knight and slowing white 's attack considerably it seemed to me, but after 5 minutes of thought(it was a rapid game) I found : ... fxe6 15. bxc3 I lost the game because I played badly (The fact that my opponent outrated me with more than 500 points played also a role). |
|
| Dec-30-05 |
| azaris: <BaranDuin> I suppose Black can't be allowed to pry open the b-file, so White must continue with 16. Qxf7+ Kd8 17. b3 Nxe4 18. Bg2 Bb7 19. Bxe4 Bxe4 20. Qxg7 Re8. I'm not sure if there is enough comp. |
|
| Dec-30-05 |
| JustAFish: <RonB52734> If it's any consolation, I played the exact same game during my trevails with the Najdorf about a year ago. |
|
| Dec-30-05 |
| BaranDuin: <Azaris> I played Qxf7+ but now i think exf7+ is better. After for example ... Kf8 17.Qxc3 Kxf7 18. Bc4+ Ke8 19. Bd5 Bb7 20. Bxb7 Qxb7 21. Nf5... White has a very goed position. |
|

 |
| AdrianP: <Baranduin> I'm not sure about Kxf7 in your line, allowing White to develop the attack with tempo. I think Black needs to leave the pawn there for the time being to provide some protection for his king. |

| soughzin: Can anyone with a little experience in this line help explain the differences in the 7th move options for black? I've looked into b5 already and see the unique motives there but I'm wondering about Be7,Nbd7 and Qc7. Thanks |
|
| Nov-11-06 |
| Kean: good question. i dont know about b5, but i like qc7 for it switches the q, from the file of the white rook down there to the c-file. there she fortifies e5 & c4. then b5 could be played, bb7 and the bishop has a good diagonal, straight to the white q; nb6-c4 & the kt is supported by the q & b5. also the q is eyeing c2 & now any rook can go to c8, strengthening the pressure along the file. hey the najdorf is great! |
|
| Nov-11-06 |
| Stanley Yee: Look up "Mastering the Najdorf" by Arizmendi & Moreno on Amazon.com which favours 7...Qc7 or 7...Nbd7 as they both cover the e5 square, although there is certainly nothing wrong with the solid 7...Be7. Read the book reviews. There is so much material out there on the Najdorf that a repertoire book is about all the memory can handle, and this book is excellent. |

| AdrianP: <Soughzin>
A quick summary:-
(1) 7. ...Qb6 is the poisoned pawn, which is the main reason why most White players have moved onto 6. Be3 rather than 6. Bg5. It's been more or less analysed to a draw. See Vallejo Pons v Kasparov, Linares 2004 1/2-1/2 for one of the main lines. Both sides really need to know their stuff to avoid losing - as a generalisation, White needs to keep sacrificing material and Black needs to keep finding only moves. (2) 7. ...b5 is the Polugaevsky variation which is just as hair-raising as the poisoned pawn. There has been no 'refutation' of 7. ...b5, but its popularity has dropped off. (3) 7. ...Be7 is the (old) main line, followed by 8. Qf3 Qc7 9. O-O-O Nbd7 and then either 10. g4 or 10. Bd3. There's a huge amount of theory including lots of interesting sacs and still some new ideas, but Black seems to hold his own. (4) 7. ...Nbd7 is similar to 7. ...Be7 and can transpose. It's a favourite of Gelfand's and the main point is to control e5 asap and maybe save a tempo if the bishop is more comfortable staying on f8. Again, there's lots of theory. Gelfand beat off Carlsen, Radjabov and Nakamura in succession in recent times in this line. 7. ...Qc7 is also OK and tends to transpose.
