Kibitzer's Corner
Jun-19-04  shr0pshire: 25. Qxc5 --- Seems to me at this point that white is eating some pawns, and his queen is poorly placed. I think that black is in slighty better position.

26. ... Nxf5 gets one of the pawns back.

Then out of no where 27. Ggxg5!

Then the game gets complicated any game so far in the FIDE championship.

I think that it can be classified that Nielsen used a double rook sacrifice in this game to get the win.

Is this sound? I would have to put this into my computer later today to see how sound it is. I can't break this down on my own.

I think this is an amazing games. I look forward to more of this from Nielsen.

Jun-20-04  DoorSmashingRampage: I am new here, and this is my first kibitz.
I guess this will improve the Nielsen ratings!
Jun-20-04  iron maiden: <DoorSmashingRampage> Welcome to the site. Hope you're nothing like your username! :-)
Jun-20-04  DoorSmashingRampage: Sorry about copying that pun; I didn't read the caption. I am nothing like my username. I am a big guy(260lbs), and although I'm sort of a gentle giant, some of my friends are afraid that someday I will snap, and go on something like a door-smashing rampage. So don't get me angry!
Jun-20-04  shr0pshire: To answer my own question, the sack isn't completely sound. Neilsen starts out on move 26 with a +2 margin. Then at move 34 it is a -1.14.

Black makes a few poor positional moves, then white gains momentum and doesn't lose control from there.

Very nice exciting play by Nielsen with what looks like a pretty sound sacrifice.

Jun-20-04  shr0pshire: In case the rook sacrfice isn't enticing aristarch recommends 27. Nf4 instead.
Jun-20-04  MatrixManNe0: hmmm, looks like no questions (except for shr0pshire, whose I cannot answer, as he has already answered his own question...)

Yes, the ending is great! 41. d7 Qg8 (the only move, as no other moves stop the pawn from queening, as 41... Kc7 is met by 42. d8/Q+!, and the king must move, as it is double-check, and 41... Rd1 is simply met by dxc8/Q, while 41... Rd8 could be simply taken) 42. Qd6+ followed by 43. Ne7, forking queen and rook, and eventually queening!

Jun-20-04  Dillinger: my vote for saturday's best game is Aleksandrov vs E El Gindy, 2004 for its tactical subtleties
Jun-20-04  kevin86: A nice combination to force a queen by white!

  plang: Game 1 of their first round match in the Tripoli World Championship tournament; Nielsen also won the second game clinching the match before being eliminated by Radjabov in the second round.

The line 10..Bd7 originated in 1980 and is an alternative to the older line 10..Bg4 11 f3..Bd7 (11..Na5 is the main line). There had been two previous games where 14..cxd had been played; 14..Rad8 was new. 22..Kh8 23 e5!..Nxf5 24 Bxf5..Bxf5 25 Rxf5..gxf 26 Rg3 would have been winning for White. Nielsen's sacrifice 27 Rgxg5?! was over-optimistic; better would have been 27 Nf4. 36..Qb6+? was an inaccuracy giving White a tempo to break the pin on the first rank; 36..Qg6 or 36..Qf7 were alternatives when the position would have remained unclear. The sharp game would have continued after 39..Qf7! 40 Be2..Kd7 41 Nh6; instead after the blunder 39..Kd7? the game was over.
