Oct-31-07  ounos: Excellent finish!
Oct-31-07  syracrophy: What kind of idiot would dare to make so useless sacrifices, against a top class master like Carlsen? The idea of 20.♘xf7?! was to play ♖e3-♖f3, but the refutation was delightful. 20...♗xd4!.

After 24...♖xd8 <Four moves after 20.♘xf7?!> White's completely lost! Black will keep all of his three pieces, since 25.♕xc3?? it's impossible, in view of 25...♖d1+ 26.♔g2 ♘f4+ 27.♔g3 ♘e2+ and 28...♘xc3

And after 25.f4 ♖d4!!, White's roasted. Once more, 26.♕xc3 loses, now to 26...♖d1+ 27.♔g2 ♘xf4+ 28.♔f3 ♖d3+ <28.♔g3 ♘e2+> and curtain's down.

And after the queen moves, all of White pawns will fall like ripe apples

Oct-31-07  rover: The only thing worse is if you don't play a winning move becouse you assume your higher rated opponent saw something you didn't.
Oct-31-07  Shams: <What kind of idiot would dare to make so useless sacrifices, against a top class master like Carlsen?> as opposed to hunkering down and letting him slowly squeeze you? why not go for glory? if you see a refutation you don't play a sacrifice; if you don't see it, and you like your chances, you play it-- regardless of opponent. I'd rather lose like this to Carlsen than show my kids a boring 70 move endgame loss in twenty years.
Oct-31-07  Whack8888: probably he just missed 25. Qxc3? Rd1+ 26. Kg2 Nf4+ 27. Kg3 Ne2+ forking Queen and King. This is a tough Knight fork to see, especially as he may have rushed through this line a bit deeming it impossible for Black early on.
Oct-31-07  Shams: another question-- what was Magnus' idea behind 19...Qf5<?> defensively, all I see is it prevents 20.Ng4 and 21.d5. Surely there was a lot deeper idea behind it
Nov-01-07  lentil: <Shams> 19. .. Qf5 reveals the B attack on the N/e5 and threatens 20. ... Nxd4 etc, winning a pawn. Of greater interest to me is whether Carlsen saw the whole continuation before playing the move...

Absolutely stupendous tactical vision by Magnus.

  patzer2: Carlsen's Queen sham sacrfice 22...Qxf3! wins three decisive pieces (Rook, Bishop & Knight) for the Queen because of the threat of a Knight Fork after 25. Qxc3 Rd1+ 27. Kg2 Nf4+ 28. Kg3 Ne7+ (forking King and Queen).

This variation is an excellent example of Magnus Carlsen's simply outstanding <CALCULATION/VISUALIZATION> skills and shows what can be accomplished with such ability: you see that 22 ... ♕f5x♖f3! wins ♖♘♗ for ♕ while your opponent does not.

I just love this ending tactical sequence by Carlsen.

After 25 ... ♖d8-d4!, the <UNDEFENDED> Black c3-bishop is taboo (26 ♕c4x♗c3??) because of the <KNIGHT FORK> and <ROOK FORK> positions shown above.

A great example by Carlsen of <*FORCING(!)* YOUR OPPONENT TO LINE UP HIS PIECES>. After 27 ... ♘e6xf4+, the White g2-king is either <FORCED> onto the g3-square for a <KNIGHT FORK> or <FORCED> onto the f3-square for a <ROOK FORK>.

*FORCE(!)* YOUR OPPONENT TO LINE UP HIS PIECES!

Those of us that own apple trees will know that ripe apples tend to cling to their trees like poo-poo clings to blankets.

Feb-01-17  Timi: Just watched the new video of Jonathan Schrantz about the Semi-Slav and I think the move 21 by black should be a sunday puzzle or a saturday one, so... 21... Black to play and win.
Mar-17-17  Dirkster: I think this guy Carlsen may be someone to watch - he seems to know his stuff... WOW!!!

  Cheapo by the Dozen: LOL.

Anyhow, I went with 22 ... Bxc3. If it was necessary to open a flight square for the White king with the game move, I haven't seen why.

The basic idea in either line is that if White pauses to recapture at c3 at some point, he gets mated. But if he doesn't, Black has rook and 2 pieces for the queen.

Also, in my line but not the game line, Black can have a rook at d4 which can then interpose at f4 to break the pin of his queen.

One subtlety in the whole thing is that White's d4 pawn is hanging, because if White's queen wants to keep pinning the Black knight that covers d4, she won't be able to take at d4 herself.

  PhilFeeley: I got Bxd4, but missed the queen sac, although in retrospect, it's forced as the queen is pinned.
Mar-17-17  yadasampati: Why does white not take the bishop with 25. Qxc3? The answer: Rd1+ 26. Kg2 (forced) Nf4+ 27. Kg3 (forced) Ne2+ and black wins the queen.

  Boomie: ->

The coordination of the rook and knight is lovely. Notice how they prevent 25. Qxc3.

24...Rxd8 25. Qxc3 Rd1+ 26. Kg2 Nf4+ 27. Kg3 Ne2+

The bishop is also immune in the game continuation.

24...Rxd8 25. f4 Rd4 26. Qxc3 Rd1+ 27. Kg2 Nxf4+ 28. Kf3 Rd3+
