May-04-08  kingsindian2006: very fun game to watch, i guess im a new fan of the nimzo classics..
May-04-08  whiteshark: From the Tournament Bulletin:

Carlsen-Adams was won by the Norwegian, who demonstrated a modern attitude to the game: he had delved deeply into the mysteries of this Nimzo-Indian line [his <19.Nd4> was new]

and throughout the game he overcame the natural fear for material losses.

Carlsen: "For the exchange White had good positional compensation, but for a while it was about equal. But then he should have taken on d5 [instead of 30...Kf8 – PD]. I got some advantage and then I was lucky I had this trick with 42.Rb8."

Adams: "It was an interesting opening position. Today I didn't really like it, but probably it's all right for Black. I looked for ways to give back the exchange but the way I did it was ridiculous."

Shipov recommends <26…Ne5!>

with the idea 27.Rd1 a5! 28.bxa5 Rxa5 29.Bxd5 Ke8! 30.e4 Rxc5 31.Bxb7 "with absolute equality"

He considered Black's last chance to be <40...Rxe4>.

May-04-08  PinkPanther: Somebody seriously needs to buy Adams a @#$%ing endgame book.

May-04-08  notyetagm: White to play: 29 ?


click for larger view

Here Carlsen (white) played the lovely 29 b4-b5!, apparently putting the White b5-pawn <EN PRISE> to two different Black units (Black c6-bishop,a6-pawn).

Position after 29 b4-b5!


click for larger view

Why can't Black simply win a pawn by capturing the White b5-pawn, which has two attackers (Black c6-bishop,a6-pawn) against zero defenders?

Because <OBLIGATION RESTRICTS MOBILITY>!

The Black a6-pawn meets the threat of ♖a1x♖a8 by <BLOCKING> the a-file, so the Black a6-pawn cannot leave the a-file without Black losing a rook. That is, the <OBLIGATION> to <BLOCK> the a-file <RESTRICTS> the <MOBILITY> of the Black a6-pawn to the a-file.

And similarly the Black c6-bishop is meeting the threat to the Black d5-pawn,d5-square by <DEFENDING> that square, so the Black c6-bishop cannot leave the a8-h1 diagonal without losing the central d5-pawn. That is, the <OBLIGATION> to <DEFEND> the d5-square <RESTRICTS> the <MOBILITY> of the Black c6-bishop to the a8-h1 diagonal.

So if the Black a6-pawn is <RESTRICTED> to the a-file and the Black c6-bishop is <RESTRICTED> to the a8-h1 diagonal, what does Black have <DEFENDING> the b5-square from the threat of 29 b4-b5! ? The answer is -nothing-, and so Magnus (White) plays 29 b4-b5!.

<OBLIGATION RESTRICTS MOBILITY!>

http://www.chessdom.com/chess-grand...:

<29.b5!? A good trade for white. He couldn't win d5 for nothing, but now his Bishops are grabbing some nice diagonals and Knight can be very annoying.>

  chancho: Mickey noticed to his horror that 56..Kd5 runs into 57.Rxc6! winning a piece for Carlsen.
May-04-08  Gilmoy: Or simply 57.Kxg2, and Black must drop the P or B also.
May-05-08  notyetagm: <chancho: Mickey noticed to his horror that 56..Kd5 runs into 57.Rxc6! winning a piece for Carlsen.>

56 ... ♔d7 also runs into 57 ♖x♗c6! <REMOVE THE GUARD>.

May-05-08  notyetagm: Position after 29 b4-b5!?


click for larger view

29 b4-b5!? is very reminiscent of how Black plays ... b7-b5 in some lines of the Benoni.

Here the Black c6-bishop is <OVERWORKED> defending both the b5-,d5-squares. In the Benoni with ... b7-b5, it is the White c3-knight which is <OVERWORKED> defending both the e4-,b5-squares.

May-05-08  Magnusch: After black played 53.. f4 , I was thinking 54 Bxf4 was winning.

54.. Nxf4 55 Ke3 Nd3 56 Rd6+ (or Ra7+) K move and 57 Kxe4 Nxc5+ 58 Kd5. And now an endgame Rook - Knight. Isn't this winning? If it is winning, is it difficult to win (number of moves and so on)?

Tank you great players for an answer!

May-05-08  euripides: <Magnusch> R vs N is generally drawn, with two main exceptions: if the knight is separated from its king, or if the pieces get themeslves in a tangle in the corner, the rook may win.
May-05-08  Magnusch: <euripides> Thank you for your answer! Seems logic. Knight stronger than bishop in shorter distance, and if it is a long way from the king it cant move so fast as the bishop. And the knight don't feel so good near a corner.
May-05-08  karik: Damn I hate those arbiter moves! Adams surely didn't play 56. -Kd5 but the stupid arbiter did. And it will be repeated in every game collection from now on.
May-05-08  hardliner: Adams had only 39 sec on the last three moves before time control. Typical Carlsen to get this kind of game development, basically winning the game in the last moves before time control.

And yes <karik>, the arbiter moves should be prohibited. There must be an other solution!

May-06-08  Atking: <<Whiteshark> Shipov recommends <26…Ne5!> with the idea 27.Rd1 a5! 28.bxa5 Rxa5 29.Bxd5 Ke8! 30.e4 Rxc5 31.Bxb7 "with absolute equality".> On the obvious 27.Bxd5 I suppose 27...Nd3+ 28.Kg3 Rah8 with R4h5 (xBd5)orh6 (on f4) and Rg5org6 mate!? But what if simply White plays 31.Ba3 ?
Jun-02-08  PinnedPiece: <karik: Damn I hate those arbiter moves! Adams surely didn't play 56. -Kd5 but the stupid arbiter did.>

????
Could someone explain? Seems to say a third party can write down unplayed moves....

Jun-05-08  Jolly Wally: @PinnedPiece - I think he's referring to the means by which the arbiter tells the computer system that a game is finished when a player resigns. From what I know this involves placing the white king on d5, and I think the black king on e4? Something like that... Anyway in some situations like here, this move the move is still legal, and so the system registers it as a move and this is then broadcasted, to the confusion of many.
Jun-07-08  PinnedPiece: How interesting, and archaic!
Dec-31-08  sozinattack: Sorcery by Carlsen.
Nov-10-12  fisayo123: This is like white plays to win. Every white move from the exchange puts Adams to the sword. Carlsen is a wizard!
Aug-01-14  whiteshark: Artur Jussupow and Jan Gustafsson gave a fine lecture on this game: http://www.chessdom.com/magnus-carl...
