|Jul-07-04|| ||tomh72000: Wow, is this the only variation where the "practicioners" list is topped by the same player as both white and black? |
|Nov-21-04|| ||schoolsucks: Has Qb3 been played before in the QID? I've scored a pretty nifty win with this as white with a pawn and piece sac to gain the initiative on USCL. In fact I think it makes a tactical line out of this "boring" opening.|

|Nov-21-04|| ||pawn52: <schoolsucks> It has happened before. Some examples are games 9, 1, and 13 on this page:
I know it says a different opening, but my database on Fritz 8 says that these three games are Queen's Indian games. As for you game, I've got Fritz 8 going right now and will post analysis from it in a few minutes.
|Nov-21-04|| ||pawn52: <schoolsucks> This was a very good game. An alternative on move 12 would be Nf2!? with a huge advantage in White's favor. 8.f3!? prevented intrusion on the e4 square. 4.Qb3!? was a nice idea, attacking the bishop and beginning to place pressure on the e6 square. After 5.d5, the pressure would be intense on the e6 square. |
Keep up the good work!
|Nov-21-04|| ||Dudley: The game was very good but the opening is a Nimzo-Indian Speelman variation. 4.Qb3 c5 is the best move for Black. The Queen's Indian occurs when White avoids the Bb4 pin by moving 3.Nf3 instead of 3.Nc3. Fritz 8 called that a Q-Indian? The themes are similar in any case. |
|Nov-21-04|| ||pawn52: <Dudley> Oh, okay. Thanks. |
|Apr-09-05|| ||kevinatcausa: The variation continuing
4 ... Ba6
5 b3 Bb4+
6 Bd2 Be7
7 Bg2 c6
8 Bc3 d5
has been played 109 times, of which 72.5% have been draws. Is this the most drawish position reached at least 100 times?
|May-21-05|| ||cuendillar: No, it isn't. This line is played 166 times with 92,5% draws! 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 Nc6 5.Bf4 Bf5 6.e3 e6 7.Bd3 Bxd3. Then there are of course a few forced draw lines|
|Dec-01-05|| ||DutchDunce: Some dude named Darmen actually dared 4...Bb7 against Aronian's 4.g3. Result: a quick 1-0. The ONLY correct response is 4...Ba6, as all top GM's and DD's (Dutch Dunces) know.|
|Apr-05-06|| ||WTHarvey: Here's a collection of 20 puzzles from Queen's Indian (E15) miniatures: http://www.wtharvey.com/e15.html What's the winning move?|
|May-23-06|| ||Microbe: <Dutch Dunce> as I am someone interested in the QI as an alternative to the nimzo-indian, may enquire as to WHY 4... Ba6 is the only good response? I realise that it attacks the c pawn and forces a defence before moving back to b7; but why is going straight to b7 so bad? I mean it pins the knight straight away which is a good thing isn't it?|
|May-23-06|| ||Mating Net: 4...Ba6 is superior because it forces White to make a choice with respect to defending the c pawn. None of the choices are optimum responses. Each one makes, albeit minor, a concession to Black.|
The pin on the Knight is not relevant at all because it is already defended & Black can not attack the piece straight away.
|May-23-06|| ||euripides: <This line is played 166 times with 92,5% draws! 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 Nc6 5.Bf4 Bf5 6.e3 e6 7.Bd3 Bxd3.> |
Remarakble indeed. The interesting question is: in how many games did Black take his own pawn ? and in how many did he take the opportunity to nudge it to c5 ?
|May-24-06|| ||Microbe: Thanks very much <CRWynn> and <Mating Net>! Put my mind at ease =)|
|Feb-02-07|| ||cuendillar: <euripides> I obviously forgot to include 2.5 cxd5 cxd5 (non-integer move number due to inserting the move afterwards.)|
|Jun-24-07|| ||hamworld: I don't get it. Why would white play Nxd7 in 1 d4 Nf6 2 c4 e6 3 Nf3 b6 4 g3 Ba6 5. b3 Bb4+ 6. Bd2 Be7 7. Bg2 c6 8. Bc3 d6 9. Ne5 Nfd7 10. Nxd7|
|Jul-20-07|| ||Amorphous Codeine: Similar question as the one posted above. What advantage does playing the 9.Ne5 Nfd7 10.Nxd7 manoever give white?|
1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Ba6 5. b3 Bb4+ 6. Bd2 Be7 7. Bg2 c6 8. Bc3 d5 9. Ne5 Nfd7 10. Nxd7 Nxd7 11. Nd2 gives this position:

Whereas simply playing 9. Nbd2 gives this position:

Both positions have black to move. The only differences in the first position as compared to the second are that the f3 and f6 knights are removed, and the b8 knight has moved to d7. I don't see how that benefits white in any way!?
|Jul-20-07|| ||ganstaman: It might have something to do with control of the e4 square (apparently, that's what the QID is all about). Removing the f6-knight removes a black defender of that square, and removing the f3-knight opens up the g2-bishop as a white attacker of that square.|
I think that's why in the World vs. GMYS game, we played 12...f5 instead of the more normal 12...Rc8 (Opening Explorer). We wanted to prevent an e4 push by white, which when looking at the diagrams, seems to have been in white's mind.
|Jul-20-07|| ||Amorphous Codeine: aah yes, e4. that explains it, thanks!|
|Aug-25-08|| ||refutor: what's the idea behind tiviakov's 4th?

|Sep-21-08|| ||Cactus: <refutor> Preparing ...d5. With the bishop on a6 rather than b7, and the qeen's protection about to be lost (after Nd7) the d5 pawn needs a little extra protection.|
Now for a question of my own. Here Opening Explorer the move Nd3 has only been played once. To me it seems like a strong move simply becuase the knight on b8 really has nowhere to go; a6 has a bishop, c6 has a pawn, and d7 has a knight. Is there a reason Nd3 isn't being played much?
|Apr-21-10|| ||LDJ: I also have a question. In the line 1.d4 Nf6 2.c4 e6 3.Nf3 b6 3.g3 Ba6 5.Qc2 Bb7, why does Black provoke 5.Qc2 en then retreat his bishop? (Why not immediately play 4...Bb7?) To me, it doesn't seem to be a concession, Black just seems to lose a tempo. But I'm not a GM, neither a QI-expert.|
