My response to the Queens Gambit:

Please analyze just up to move 11, as to whether this is a good opening variation for Black. My opponent blundered on move 12, so no point in analyzing beyond that. We each had 10 minutes but used only 90 seconds each.

We both did an experimental beginner version of the Queen's gambit. My opponent opened advanced e4 early, and I counter attacked the pinned d pawn with e5, which I plan to do again. I don't know if my system is good, but I really like how non-cramped black's position is and how it allows fast easy development and pressure on e4.

My opponent later blundered twice on moves 11 and 12, first throwing away the knight, and then making the king an easy target by advancing the g pawn. White resigned on move 17. I don't think checkmate could be forced, but white was about to lose a rook and maybe have to lose more material to get my pieces away from the king.

Maybe it would have been a bit stronger for me to play Nf6 before Nd7, to prepair for the worst. My d7 knight has a nice view of c5. One other possible mistake is that my bishop moved twice, first to d6 and then to c5. I wonder if it would have been better to go straight to c5.

My opponent could have guarded the e pawn with Qc2. Even after throwing away the night, Bf3 could have saved the king, or even Nxe4 followed by Bf3 and if necessary Qxf3 to fully neutralize the attack. Being a piece down is not disasterous in a lower rated game.

if you are talking about 3...e5 then yes it is good i dont remeber if its theory but i think that it is

on the 5th move your opponent should have played 5.a4 and take back his pawn i dont know why he didnt do that.

Your opponent should play 4.a4! 

Nf3 is not so good.

7.Nd4!? is interesting as if exd4, Bxg4

If bxe2 Nxe2 and if anything else, Nxb5 works out well

8.Bb4! Is splendid. 

10.Bxe2 is the best move. You're a pawn up, your opponent has given you the chance to trade, grab it! You also get a tempo to castle, where Bg6 was useless.

11.Qc2 is better

In Queens Gambit where black has taken in c4 he has to think very carefully before trying to protect that pawn with b5. Sometimes such tactics are viable but here 4... b5? is just bad: white should play 5. a4! as indicated and black cannot defend the extra pawn. Instead black could try to develop and put pressure on white's centre with something like 4... Nf6 5. Nc3 c6 6. Bxc4 b5 7. Bb3 b4 which should be quite good.

Also, for white 4. Nf3 is considered a better try to get an advantage so you are probably likely to meet that in the future.

Finally, despite what Vyomo says 10 ... Bg6 to me seemed quite strong as it's not readily apparent how white can protect e4. At least it worked beautifully in the game.

Bg6 Qc2 is the best, however Ng5 is horrible, so it doesn't really matter what you play, black has a clear +.

10... Bg6 11. Qc2 Nxd5

Shakaali, what about a4? a4 h6 Nf3 Nxe4 axb5

Do you mean 10. a4? I suppose that could be played. If possible black likes to retain the integrity of his pawnchain on the queenside (+ his extra pawn!) and therefore I believe he should reply with 10... a6.

Thanks for all the analysis. I'll set it up and look over it, since it is nice to know a few traps. a4 will make me think twice about playing b5. I agree though that it is better to just practice tactics and positional improvement rather than memorizing book responses my opponent probably won't stick to. It seems like if I accept the queens gambit, I'm guaranteed to trade a center pawn for a c pawn, and have trouble putting my knight on c6. I think I'll just develope my bishop to f5 early before e4 can be played and before it can be trapped with the d pawn going to d6, and then I'll develop my knight to d7 and meet Nc3 with Ngf6.

I don't want to learn the whole opening. I just want to know a 3 move way to keep my good pawns and still not have cramped development of my queen side pieces, and then continue developing almost like it is a king pawn game. I think I can do that just fine with the analysis I was provided.

Fantastic! Yep. Once White wasted a tempo with Ng5, and also with h3, there was no longer time to defend e4. Nice pin.

Yes, white needs to play a4 before black developes the queen bishop and knight. Once the rook and queen are connected, a4 loses its pinning power.

As far as that game goes, it's a poor example of White playing Queen's Gambit. Try e5 on someone that plays e3 instead. I had a game that went like that, but I can't remember the exact lines. I do remember losing material due to a novice mistake, but it was the first time I went through that line.
