| Dec-17-02 | | JustAFish: Could someone explain to me why 6 dxc5 is not good? It seems to me like it either wins a pawn or blasts the king out into the open. Is it because, after ... Qa5 it allows the b8 knight to go to eventually go to d4? |

 | | Honza Cervenka: It seems to be that 6. dxc5 can give quite good play to black after 6...Qa5. I know only one game with 6. dxc5 - Bisguier vs Najdorf, 1955 - but I am not sure that it is definitely bad for white. Of course, 6. d5 restricting black's mobility and space is a logic and good move. |

| Dec-17-02 | | judokausa1: Well I can give you a basic idea Justafish. The main reason dxc isn't good for white is that it releases the tension in the center. Combined with the fact that white will have no good outposts for any pieces while black has an excellent one on d4. combine this with opening the a1-h8 diagnal. Also of note is that it breaks the basic rule of never opening the game up when your behind in development. Whites king looks a long way from castling and black is going to start pouring on the pressure. Winning the e pawn for white will more than likely be his death after 0-0 and Re8. |

| Dec-17-02 | | PVS: Specifically 6. d5 chases away the knight so black has to waste a move and post the knight poorly. |
|
| Dec-18-02 | | JustAFish: Thanks for the assistance, folks. While not an obvious blunder, from what you all say, I'm pretty much convinced that 6. dxc5 allows black to at least achieve equality because of the need for white to counter the simple threat against the e4 pawn after 6. ...Qa5. In the Bisguier game, this allows Najdorf to get another piece out and regain the pawn. |

| Dec-04-04 | | Backward Development: of interest:
after black's sixth move
"A lot has already happened in the first six moves. Taking advantage of the white queen's biship's development to g5, instead of the usual e3, where it participates in the struggle for d4, black quickly counterattacked the white center with ...c5, since 6.d5 kept black's knight from developing to c6, najdorf now intends to bring it to c7, so he can prepare g5 with a6. This costs a lot of time, however, and the result obtained is disproportionately small, compared with the amount of effort expended. The knight occupies a passive position on c7, wher eit remains unemployed for some time. In the end, it nearly costs black the game."
after white's 23red move
"small advantages, patiently accumlated, have grown into a sizeable stack; now with this move, white begins his search for the decisive strengthening of his position. The threat is
24.nf4 g5
25.ne6 gh
26.nxf8; additionally, his last move helped fix the black e and f-pawns on dark squares.
Still, white might have given some thought to the transfer of his bishop to a different diagonal. It has already done its work here by inducing f6 and might have caused black considerable grief after 23 Be1. 23 Ra1 was also possible, but although an immediate...f5 would not work in view of
24.e5 de
25.d6+ kh8
26.de etc., white would always have had to consider an eventual...f5 anyway."
after white's 27th move
"Why did white sacrifice that pawn? can't black begin a counterattack now? not yet, and only meanwhile, white needs only two or three moves-nc3 and Rb1, for example-to take over all the key points on the queenside and then to pick up the c5 or the e7 pawn. the knight's poor placement at a8 helps white greatly in the execution of this plan."
after white's 34th
"Practically all of white's advantage disappears after the exchange of rooks. Better was
34.Rxe7 Rb3
35.Bxf6
or
34...Bd6
35.Re6 Be5
36.Bxf6 Bxc3
37.Bxc3 Rb3
38.Ba5!
White overestimated the strength of the pawn at d3 in rejecting this continuation, although his pawn on d5 would have been much more dangerous.
The best line of all would have been 33.Bg3, instead of 33.Kf3, offering to exchange bishops. However white had overlooked black's reply, 33...Rb8." |

| May-21-09 | | superstoned: Even Bronstein, world champion candidate, can miss what a comfortable armchair analyst at home might consider obvious during the heat of battle. He "overlooked"? the point of the Bh6-f4 maneuver, which allows Black the freeing Rf8-b8! Kinda puts things in perspective. |
