  Eyal: <keypusher> 38.Kh1 re-establishes the deadly threat of Nc6 - where Black doesn't have Bc5+.
Jul-28-07  Gegga: Carlsen is King!
Jul-28-07  Gegga: Magnus means "the great one", or "the big one".
Like in "Magnum".

Magnus really is great!

Jul-28-07  peabody88: 29...Rd5 would have allowed Oni to stay in the game. 30.a3 Rd8 31.Rc1 Na4

  Marmot PFL: I gather that Onischuk was short of time, still I am surprised he would play into a pin like that. Good came by Carlsen.

  patzer2: Carlsen's clever 29. b4!! sets a trap which leads to a winning pin after Black takes the bait.

We don't have to choose: Magnus annotates both of these games in New In Chess Magazine 2007/6 (http://www.newinchess.com/Magazine/...). :-)

Great summary, as always.

Apr-17-08  Jolly Wally: This game is a work of art.
Jul-23-08  Mulyahnto: after b4!, a cheap pawn grab Bxb4 by black. The only safe square for the black rook is Rb7 making it all but impossible for black to avoid the pin.

  notyetagm: White to play: 39 ?


click for larger view

Carlsen (White) simply <REINFORCES THE PIN> on the Black b4-bishop to the <UNDEFENDED> Black b5-rook with 39 ♘e5-c6 and Black resigned.

Position after 39 ♘e5-c6 <reinforce the pin> 1-0

A more picturesque example of <PIECE COORDINATION> you could not ask for.
