Attacking is just another part of a deep positional understanding. A planning implies positional understanding, and the typical plan is an attack. Also, your opponent is talented. Not many 11 years old girls can play at the 1150 level.

I prefer 1...e5.

Yes black can try e5, its a Sicilian Reverse.

Nimzo Indian defense are good opening against white d4, this is my favourite reply to queens pawn opening aside from my opening repertoire King's Indian and Gruenfeld.

I would have simply done ..e5, which is more active than this e6 move.

2...e6 keeps the options of both the Nimzo Indian and Ben-oni and was the move preferred by Fischer.

This can be transpose to Reti Opening after 4.g3

Black adopted the Tarrasch defense notable for isolated pawn in exchange of good development of his pieces..

or "her pieces"  

Instead of 7. e3, 7. g3 followed by 8. Bg2 are much ok, since it add the pressure in d5 square. This position is resemblance between Akiba Rubinstein (white) and Capablanca in 1911 San Sebastian Tournament 1911, in which the Rubinstein crushed Capablanca in an endgame battle.

This is more or less the correct idea. However, at this level of play, most often one player loses because he self destructs and messes things up himself, not because the opponent played brilliantly(in fact, I have seeen this latter case only 1 time-The player uncorked an amazing speculative combination, like Tal.). Still, it is good to keep the pieces active as best as you can. 7.g3 is fine.

7. Bg5!? is a aggressive move that might be okay in this position. After 7...d4!?(I know, 7...0-0 is safer, but I want to examine the really sharp play first)8. Na4 Bb4+ 9. Bd2 Qa5 10. Rc1 Bd7 11. Nc5 is perhaps a slight advantage for White.

The Rubinstein set up is strong. There are other ideas but the essential feature of this position is the fight for control of d4, the blockading square.

I'm not sure that advancing the d-pawn is really the plan Black should be going for here, and perhaps she isn't (wasn't).

@ionadowman, you are correct. Although still the position is equal, black should neutralize the isolated pawn by means of developing her pieces on the right direction, like supporting the d pawn by Be6. Its a psychological on the part of the black, she must have a flexible plan, develop the pieces on the queenside but always look the possibilities on switching these to kingside to provoke white to weaken his position. Black should avoid white chances to simplify the position by exchanging the pieces, because the primary objective of white is clear cut strategy towards the endgame because he have an active two bishops.

Black should be aiming to advance the d-pawn, so that White cannot blockade it and get a bind.

Bg4 pinning knight always give a lot of headache for white. this is a psychological move to provoke white to advance his pawn in h3 which added weakness on his pawn structure.

Maybe 9...a6 is better?

This bishop move is in keeping with quick development, and a plan to develop a K-side attack. Other plausible moves seem to be 9...a6, 9...Qb6 or 9...Re8.

According to Nimzovitch the bishop belongs on e6.

The position are even, although black have isolated pawn which could be utilize by white the d4 square

Again, i wonder why black didn't play 10...a6? At least it prevents white's next move.

...a6 would have forced White to make a good move ....Nbd4. The weakness of the isolated pawn is the square in front of it, and the ideal blockader is the knight. It is therefore good to have your blockading knight backed up by a second knight.

Yet that is what Black should have played: 11...Bxe2 12.Nxe2 (12.Qxe2?? loses a piece) 12...Rc8 and Black's more active game must surely give her a bit of an edge.

Wrong knight, better is 11...Nbd4.

That is right.

In this position, I'm not sure that the bishop pair confers much of an advantage - not yet at any rate. Having said that, Black ought to have taken on e2 at move 12, better yet, move 11. At this point Black might as well continue with 13...Nxg4 (so much for the bishop pair) and leave it to White to decide from among three possible captures: [A] 14.Qxd4?! Re4 15.Qd2 Qc7 16.g3 Re5 preparing to switch to the h-file. The weakened light squares and the temporary immobility of White's Bishop suggests a promising game for black, here. [B] 14.Qxg4 and Black has the pleasant choice 14...Re4 or 14.Be5. [C] 14.exd4 ... Apart from anything else, this eliminates the d5 sqaure as a weakness for Black.

This is not an open position, but an isolated queen pawn position. The knight holds it own in isolated queen pawn positions.

14...bc7, with a similar idea, ought to have been preferred.

This demonstrates a very useful rule in chess: One move attacks are useless if it doesn't help to complete your development, help with your plan or cause difficulties for your opponent. It is absolutely fine to make a one-move threat if it helps you to improve your position or gain time, but otherwise, the opponent will just move the attacked piece away, remove the mate threat, and so on. If someone attacks someone's queen, they don't get points for saying stuff like"Check towards your queen!" because you will just move the queen away and what will they have achieved? Nothing! @kingshunt, should black REALLY try to make a attack on the kingside? The answer is a resounding NO! White has not made any weaknesses in the kingside and black cannot force White to make any further weaknesses there. Black should instead concentrate on getting in the pawn push d4. A attack on the center usually always beats a attack on the kingside!

Instead of obvious 15.. Bc7, black should try 15.. Ne4 centralizing his knight. this would limit the activity of white's two bishops. as well black can follow up the move later Re6 to Rh6 eyeing the Kh2 square. @raymond2002 sorry pal I'm sorry, I think you don't understand what I tried to emphasized here. You are reading my comment out of context. Please read again so you'll understand what is my point. The strategy that I suggest for black is not a superficial attack but its a planning, that's why we put all the possibilities or variations. White easily occupy the d4 square and put more pressure than black pieces. The isolated pawn is backward in endgame. White primary objective is to simplify the position from middlegame to endgame specially he is handling two bishops.

By the way, black is already having a marked disadvantage. If black wants to achieve a win(an incorrect result) he should play for it in an incorrect manner. But here a kingside attack is rather useless. Another thing is that black has no real plan in this position. All he can really hope for if white plays right is an equality. White can attack the black pawn, and has no weaknesses for black to plan on. But I think that of course black should activate his pieces maximally, so ...Ne4 was a move. I should also say that one move attacks are totally fine if they neither weaken your position nor strengthen opponents. In fact, when the position is dull and we dont know what to do, we should use one move attacks very often, even if they give us nothing. The point is that the psychology of the opponent matters a lot, and they will blunder by themselves when they see you making many of these useless threats or just aggressive looking play in general.

I'm not so sure that Black's disadvantage is so marked. Black's game is quite active, and she has a lead over White;s development. The problem is how to make progress. K-side attack is called for; Black's aim is K-side attack. Her next couple of moves seem unobjectionable to that purpose.

White's primary objective should be to blockade the d-pawn, but he no longer has the ideal blockader (a knight).

Of course after 19.Qd4, ...g6 is no defence, merely offering White a second choice of square to checkmate on. Alternative defecces would have been ...Qf8, ...Qf6,...Qg6 or ...Qh6. I might have played ...Qf6 in reply, forcing off the queens. But Black's pawn structure would have been broken up, giving White a small edge.

The reason I avoided playing 19.Qd4 was because I THOUGHT black could play 19...Qe5 with exchanges that I wanted to avoid, how come ...Qe5 isn't a possible defense to Qd4? Also I may be mistaken but it looks as though my annotation has been misread, I did say I had considered Qg4 here not Qd4 of course I seem to have missed the defense of Nf6 in response to Qg4.actually come think of it Qd4 may have been better than this since after 19...Qe5 the exchanging into a bishop vs knight endgame where black still has the pawn weakness would have been good for white. I suppose that's why you didn't mention moves like Qe5 or Nf6 as possible defenses then?

Yes Qd4 are ok than the passive Qd3, because it only hang white queen without protection @thereaper, its ok for white black's reply 19..Qe5, 20. Qxe5 Bxe5 21. Bxe5 Rxe5 then 22. Rc1 followed by 23. Rfd1, you have a small edge against black. If you want to eject the black's knight you can do this by pushing your pawn to f3 followed by Kf2 and Bh3 restricting blacks room to occupy the c8 square. Aside from these white has a good command of c file and d file.
