| Averageguy: <KingG>Thanks for the comments, but about 28.Bxf5 exf5+ 29.Kg3 I had actually hoped he would play this, because despite it being bishops of opposite colour, I quite liked my winning chances. I can play Ke8-d7-e6 and f6, my bishop can go to d5, and after b4 my king can come in via c4, or I can play g5 and h5. Still, I might be wrong. |

| Averageguy: <KingG>If you have a chess computer, then what's its evaluation of the position after the exchange into the BOOC ending? |

 |
| KingG: Ok, i checked with Fritz, and it says -1.26 before Nf5 and jumps to -0.50 after Nf5. But computers often overestimate material advantage in endgames. I think that for all practical purposes, this endgame is drawn. Of course that doesn't mean that you wouldn't have won anyway, seing as you seemed to be stronger than your opponent. But i think with best play this is a draw. Even if you can win this, you probably made the task more difficult than with keeping your knight, and ideally exchanging it for the OTHER bishop. If you could have acheived that then you would have an easier task. Do you have a plan for winning this endgame? |
|
| Oct-23-05 |
| Averageguy: Hm, the fritz evaluation was interesting. My first moves after 29.Kg3 would probably be 29...Bd5 30.b4 Ke7. My winning plan would be f6 followed by Kf7, and then launching my kingside pawns forward. Do you suggest an alternate move instead of 27...Nf5 ? |
|

|
| KingG: I'm not sure, but anything that doesn't allow the exchange has to be better. Maybe 27. ...Bd5 28.b4(threatening b5) Bc6(preventing it) 29.f4 Bb5 30.Bxb5 axb5 The point is that now White can't really move his queenside pawns, no can he attack yours as he has the wrong Bishop. So you can just put your knight on d5(tying his bishop to the defence of his b-pawn) and advance you kingside majority to create a passed pawn.
This should win.
If White refuses to trade Bishops on b5, say, 30.Bb2, then 30. ...Nd5 and you win a pawn. |

| auldoxon: I'm really surprised that 3.Nc3 is not a major line of Queen's gambit accepted. I regularly play it with a very good result. I invite everyone to discuss it. Welcome for your opinions. |

| soughzin: Is it any better to enter the QGA a move or two later or is it best to do it right off? |

| Archives: Alekhine on todays opening of the day <1.d4 d5 2.c4 dxc4 3.e4> "It is almost incredible that his quite natural move has not been considered by the so called theoreticians. White obtains now an appreciable advantage in development, no matter what Black replies." Going through Alekhines games, you can't help but notice that he generally plays with aggressive intentions in the opening. He seemed to strive for the initiative after the very first move. |

Sneaky: Here's a neat line that busts up computers (and greedy beginners) that don't have very good opening books: 1.d4 d5 2.c4 dxc4 3.e4 b5 4.Nc3 Bd7 5.a4 c6 6.axb5 cxb5 7.d5! (Hans Berliner) and now if 7...e6 or 7...e5 White plays 8.dxe6 and there is no good recapture; e.g. 8...fxe6 9.Nxb5! Bxb5 10.Qh5+ g6 11.Qxb5 "and Black wonders why he chose this defense in the first place." (Berliner) >>
Bereliner gives 7...a5 8.Nf3 as best for black. Incidentally I beat Fritz with this line. [Event "Blitz:1'+2" (with takebacks for me)]

| Knight13: Some books on this opening:
<"Queen's Gambit Accepted"> by Iakov Neishtadt. <"The Queen's Gambit Accepted: A Sharp and Sound Response to 1. d4" by Chris Ward.> (1/3 of this book is focused on 3. e4. The author claims that e4 is the real test to this opening and that it's "the way to refute the QGA.") <"Starting Out: Queen's Gambit Accepted"> by Alexander Raetsky and Maxim Chetverik. <"Easy Guide to the Queen's Gambit Accepted"> by Graeme Buckley. <"How to Beat 1 D4: A Sound and Ambitious Repertoire Based on the Queen's Gambit Accepted"> by James Rizzitano |

| Kriegspiel: I'd like more information (game collections, theoretical background, stats, citations, etc.) on this version of the QGA: 1.d4 d5 2.c4 dxc4 3.e4 a6 4.Bxc4 e6 5.Nf3 b5 and after 6.Bb3 or 6.Bd3, 6...Bb7. |

| exchangesacrifice: I didnt find any games with such moves in the Mega Database, but I think 5. f3 is stronger to protect the e4 pawn, after Nf3 Black should have a good game against the pawn ( if white pushes e5 then the d4 pawn and d5 square are weak) |
|
| Aug-10-07 |
| Kriegspiel: <exchangesacrifice> What's the "Mega Database"? Anyway, the last time the online games collection at chessbase.com was working (it hasn't been functional for the last several days at least) there were two wins by Black, two by White, and four draws, if I recall correctly, from the move sequence I gave. I don't recall 5.f3 and can't double-check on it now (because the database isn't working -- moving 1.e4 gets the response "found 0 games", and that in a database of 3.5 million games!). |

| exchangesacrifice: <Kriegspiel> Sorry to be late for 11 days but Mega Database is a databse which contains very many games http://www.chessbase.com/shop/produ...
I have the 2005 edition, but I don't believe that thngs have changed within 2 years |

| freeman8201: Has the <Queen's Gambit Accepted: Linares Variation> been refuted? I don't see it played in the new century. Anand & Ponomariov seemed to be the leaders of this line but discontinued the line in favor of the Mcdonnell? 3. e4 e5 or ala Alekhine (3. e4 Nf6). And I notice Sergey Karjakin only played the line once which resulted in a loss. After 1. d4 d5 2. c4 dxc4 3. e4 c5 4. d5  f6 5. c3 b5 6.  f4 a6 7. f3! and Black has to make a commital move he wish didn't have to.

This line is fun as black but I've had terrible results if white plays 7. f3!. I've seen some games where black plays 6... a5 but I think Ba6 is better. |

| FiveofSwords: well I also love the queens gambit accepted. I tried the grunfeld for a long time, and the slav of course, everyone just has to check out what is popular with the 'top' players. But I find that in all those lines white does have ways to not necessarily be ambitious but just restrict you (although also the exchange sac grunfeld line is just a friggen nightmare). The QGA is pretty much the only thing I found that black can be certain that he will get nice active squares for his peices. Objectively I think white remains slightly better in many lines, But black still has a position where its quite possible to outplay white, since he usully has a decent activity agains the white kingside and/or good endgame prospects with a stronger queenside and/or isolated white's d pawn. If you like the QGA you might want to check out the petroff...because the two transpose a lot. They also both have a slightly drawish reputation but this is not necessarily deserved. Black has many options in many lines and if he wants to win theres always some opportunity to play some risky move, since he has enough activity normally to support it. |

| FiveofSwords: <freeman8201>. Hmm that position in the diagram looks really scarey to me. I really would not want to deal with this as black. White is just cutting into so many sensitive parts in your position and the d5 pawn is just cruel. I can see how black might have some ideas for winning but he sure is going to have to work for it heh...i really prefer 1 d4 d5 2 c4 dc 3 e4 e5. Its nice and open and you have a lot more of your bits under control. white can usually menace your king a little but its never really quite enough. |

| FiveofSwords: <Azaris> you shouldnt go around telling people all your novelties hehe. Anyway, yeah, thats interesting, I also found this line quite a while ago and noted it as vaguely interesting. I came to the conclusion rather easily that black should not play 7..Nxe4. 7...Bc5 8 Nb3 and THEN nxe4. 9 0-0 Bb6. I think the position should be about equal, im sure that white has compensation for the pawn somewhere, but its up to him to prove it and its not so obvious. Id feel comfortable playing the black side and although a draw seems likely its not impossible at all that black manages to keep his pawn and convert it. |

| Feb-22-09 |
| FiveofSwords: <azaris> oh nevermind you mentioned that in a later post. No I dont like Nd7, white might not take your bishop, then your knight sits there looking goofy. In the game you mentioned black DID have the option of 12...Be6 13 bxe6 fxe6 rxe6 Kf7, when white restores the material imbalance but I think the position actually favors black (but pretty drawish, certainly) But if he wanted to keep the pawn then f8 was clearly the wrong square for black to mvoe his king. He simply cannot tolerate a rook on this e file for the amount of time it takes white to finially develop his queensdie to challenge it. Black was probably a relatively weak player. Kd8 is by far more logical, with the idea to play Re8 very quickly. |

| Formula7: Can Black hold on to the pawn after 1.d4 d5 2.c4 dxc4 3.e3 Qd5? |
|
| Oct-20-09 |
| Manic: <Formula7> To me it looks too dangerous. 4.Nc3 gives white a free tempo and with e4, Nf3, Bf4 coming white's development advantage looks too good, especially when the black queen presents a target for white's pieces. |
