Carlsen had to avoid an immediate 30.gxh4?? Nxf2, and now after 31.Kxf2 Qxh4+ Black has a winning attack.

If Black tries to change move order and play 29...Nxf2, then after 30.Kxf2 Nxh4:

<And Magnus had obvious difficulties in converting the position, feeling nervous.>

Not sure if I agree with that characterization :) Although Magnus didn't always find the best move he managed to keep the advantage and put Leko under sufficient pressure. Magnus has said several times in interviews that he doesn't necessarily seek out the objectively strongest moves, but practical moves which he feels comfortable with. As long as you make good moves and avoid the bad ones, it doesn't matter that much if you don't always play the best moves.

<Generally yes. There's a thin line between wasting time in simple positions & getting into time trouble and missing the win by rushing.>

With all due respect, I wouldn't say that he was playing simple positions: This game was for the most part open and tactical by nature, his king was exposed and he had to watch out for any possible counterplay by Leko. It may be easy to see the best moves in such positions when using a computer at home, but it's not that easy for a human in a tournament setting.

"the scotch game, was a rather minor line for most of the 20th century, until it was <rescued from obscurity by worldchamp gary kasparov around 1990>.However,after playing it frequently for a decade, he abruptly gave it up,saying that it was <"more risky" than the spanish and unlikely to give white advantage against perfect defense>(though its not clear which defense he feared)"

leko out soon and new ones among the junior will come in, what a bore always the same player and the same people playing over and over again, studying the same games and drawing all the time.

1.e4 e5 2.Nf3 Nc6 3.d4< Carlsen's played the Scotch 4 times as a 13 year old, but the last and only time in recent years was back in 2007 against Kamsky in the World chess cup. That game was a draw. So we may have some Kasparov influence here. Kasparov's no stranger to the Scotch, as he's played it in 3 of his world championship matches. (Karpov, Anand, Short) >3...exd4 4.Nxd4 Bc5< Leko used to play 4...Nf6, but now always seems to play 4...Bc5> 5.Be3 <Carlsen played 5 Nxc6 against Kamsky.> 5...Qf6 6.c3 Nge7 7.Bc4 Ne5 <Leko's had this position as black before against Morozevich in the Mexico world championships 2007. Morozevich played 8 Bb3.> 8.Be2 Qg6 9.0–0 d6 10.f4 Qxe4< This is all theory which will probably have to be revised after this game.> 11.Bf2 Bxd4 12.cxd4 N5g6 13.g3 0–0 14.Nc3 Qf5 15.d5 a6 16.Re1 Kh8< This may be the novelty. 1 game in the database with 16...Re8> 17.Rc1 Bd7 18.Bf3< It seems Carlsen has excellent compensation for the pawn. 2 bishops, more space and more potential for his pieces. Black's knights have nowhere to go (hence 16..Kh8 to bring the knight to g8-f6), the knight on g6 is in danger of being trapped with h4-h5. Black's queen looks a little uneasy. All in all I would say a nice position for Carlsen.> 18...Rac8 19.Qb3 <Forcing terrible weaknesses on the queenside.> 19...b5 20.Ne2 Qh3 21.Nd4 Bg4 22.Bg2 Qh5 23.h4 Ng8? <Allowing the white rook into c6 is not good, but what can black do. Carlsen controls both open files with his rooks and can double up on any of them causing havoc.But 23...Ng8?, anythings better than that> 24.Rc6 Nf6 25.Rxa6 Bd7 26.Nxb5 Rb8 27.a4< From being a pawn down to being a pawn up in the blink of an eye. >27...Ng4 <White has to be careful here. A small slip up could give black the chance to get right back into the game. All based on a possible 28...Nxh4 sacrifice.> 28.Bf3 <Black escapes with at least a draw if white plays something like - [28.Bd4?? Nxh4 29.gxh4 Qxh4 30.Rd1 (30.Re2 Qh2+ 31.Kf1 Qxf4+ 32.Bf3 Rfe8 33.Qc3 Nh2+ 34.Kg2 Bxb5 35.axb5 Nxf3 36.Bxg7+ Kg8 37.Qxf3 Qxf3+ 38.Kxf3 Rxe2 39.Kxe2 Kxg7 Looking good for black.) 30...Qh2+ 31.Kf1 Qxf4+ 32.Kg1 Qh2+ Draw]> 28...Qh6< This is a miserable place for the queen. Even the knight on g6 can't move to give his queen some breathing space. 28...Qf5 was much better. This is now just an aweful position for black.> 29.Qc4 Nxh4< Desparation time.> 30.Bxg4< [30.gxh4 Nxf2 31.f5 (31.Kxf2 Qxh4+ 32.Kf1 Bh3+ 33.Ke2 Rfe8+ 34.Be4 Bg4+ 35.Kd2 Qf2+ 36.Re2 Qxf4+ 37.Re3 f5 38.Bd3 Qxe3+ Winning) 31...Nh3+ 32.Kh2 Bxf5 and black's pieces come alive.] >30...Bxg4 31.gxh4 Bf3< Last chance, threatening mate in 3 by 32...Qg6+ but Carlsen hasn't fallen into a trap like that since he was 6 months old :-) >32.f5< Leko should just resign now. >32...Qh5 33.Qf4 Bxd5 34.Nxc7 Bb7 35.Rb6 f6 36.Bd4 Qf7 37.Ne6 Rg8 38.Kf2 Rbc8 39.Bc3 Bd5 40.a5 Rc4 41.Nd4 Ba8 42.Qxd6 Qh5 43.Qf4 Rcc8 44.Rbe6 1–0

A demolition job if I've ever seen one. Leko got into an aweful mess. His pieces weren't working and had nowhere to go. I don't think I'm being unfair to use the analogy - 'Being run over by a steamroller.'

Excellent game by Magnus! An awesome display of crushing your opponent. This game should carry an x-rated certificate.

magnus is a force to reckon , take away kasparov and he will still win these game.

i cant wait for the time for magnus to become a champion, other wise he will just become another ljubo, ljubo once upon a time is second to somebody.

He has always been more one to see everything at a glance, like Morphy, and it must be torture to go through all the variations ala Kasparov/Alekhine
