My game with Magnus Carlsen

This is my game with Magnus from the Play Live Challenge! I got to play him at the Marshall Chess Club yesterday. All 12 of us lost, although one man missed a threefold repetition draw 

I'd love some commentary on the game if anyone would like to help :) I couldn't figure out how to indicate that I resigned, so I left the last move up before my resignation 

As usual, a not particularly promising opening from Carlsen, but he just dominates the middle game.

shouldn't have pushed the pawn you gave up the center

Well, it's a King's Indian Attack. After 1. Nf3, I go ...Nf6 or ...g6. (My black defenses against 1d4 are the Nimzo or Benoni, depending on white's third move; Nf3 renders the Nimzo by transition kind of a remote possibility, so I'd play ...g3 here. In general, if your d4 defense is the Queen's Gambit, you're getting started off right. But until he commits his c-pawn, I don't like ...e6 because that keeps you from playing ...Bf5 to keep him from Bd3.

When I played d4 and got the King's Indian, I liked a Samisch set-up, but that doesn't work for either move in this case. King's Indian players love to play against d4, c4 setups without the fianchetto, so maybe Nf3 Nf6 and then if he continues with a KIA ...g6 and ...Bg7 is the way to go. For some reason, ...e6 doesn't go well in this scenario, which is why sometimes you get the KIA as recommended for white as effective against the French Defense.

I was wondering about ...Nc6 instead of ...c5. it seems you were unsure as to whether you're playing the Queen's Gambit Declined setup that it seems you started with or moving to something else. But in general blocking the c pawn with the knight isn't a good idea.

Really?

Its a white main line in general openings, so telling its not a promising opening, huh...

bad opening from black.

Your set up with Bd6 is not good because white's usual plan is to play e4, so u will have to remove your bishop d6 because of e4-e5 forking.

Your Bc8 is locked, why not developing it on f5 or g4 before playing e6?

Then what else...

Bd7, what's the point of this move?

When u play a piece, think about what u will do with it in future. Do u improve its position on d7? I don't think so, it blocks your queen, and e8-h4 diagonal is a bit useless.

I dont like your 7.d4, giving c4 square. Just simply castle and on Re1 threatening e5, u have to do something about e5, so maybe playing it yourself. As on e5 your d5 pawn would hang, just dxe4 and only then e5.

U are worse but its playable.

11...Qc7 almost loses, better was removing your Ra8, a target for Bg2.
