MAGNUS CARLSEN
(born Nov-30-1990) Norway

[what is this?]
Magnus Carlsen is the world's top ranked player and possesses the highest standard FIDE rating ever posted.

Background:

He was born in Tønsberg, Vestfold. His parents are Sigrun Øen and Henrik Carlsen, both of whom are engineers. His father taught him chess at the age of eight after which he soon played his first tournament, a junior (Miniputt) Norwegian championship. He was coached by 7-times Norwegian Champion Simen Agdestein and by Curt Hansen. He won the title of International Master in 2003 at the age of 12 years 7 months and 25 days. In 2004, after having gained over 300 rating points in little over a year, he became the second-youngest grandmaster in chess history at the time, behind only Sergey Karjakin, at the age of 13 years 4 months and 27 days. Parimarjan Negi later pipped his record by 5 days to become the 2nd youngest grandmaster ever.

Championships:

<Age>: Carlsen won the 2001 U10 Nordic Championship. In 2002, he placed =1st in the Open Norwegian Junior Championship with 5.5/7, but easily won the same event the following year with 6/6. Carlsen started with 4/4 at the 2002 U12 European Championship but faded to finish sixth. In the 2002 U12 World Championship a few weeks later, Carlsen was sole leader coming into the last round, but was held to a draw by David Howell, enabling Ian Nepomniachtchi to equal his score and to win on tiebreak. He placed =3rd at the 2003 U14 European Championship, half a point behind Sergei Zhigalko and Tornike Sanikidze, a short time later placing =9th with 7.5/11 at the World U14 Championship in Halkidiki.

<National and Continental>: A couple of weeks after being eliminated from the FIDE World Championship Knockout Tournament (2004) (see below), he placed =1st in the 2004 Norwegian Championship. However, after a 2-game play-off match with co-leader and until then, 6-time Norwegian champion, Berge Ostenstad was drawn, Østenstad was declared winner on tiebreak. In the 2005 Norwegian Chess Championship, Carlsen again finished in a shared first place, this time with his mentor Simen Agdestein. A rapid game playoff between them resulted in Agdestein’s victory by 3.5-2.5 (+2 -1 =3). Carlsen finally won the Norwegian Championship in 2006, after defeating Simen Agdestein in a tie-break match.

Carlsen’s first and and so far only participation in the continental championship in 2005 provided a solid 22-point boost to his rating when he scored 8/13 in the 6th European Individual Championship (2005).

<World>: Carlsen qualified for the FIDE World Championship Knockout Tournament (2004), but was eliminated in the 1st round tiebreaker by Levon Aronian. His hopes to become a contender for the World Championship in the future took a big step forward by placing tenth at the FIDE World Cup (2005), becoming the youngest player ever to qualify for the Candidates. In his first Candidates match in Elista in May, he drew 3-3 in the six slow games of the Candidates Match: Aronian-Carlsen (2007) before losing in rapid-play tie-breaks. He reached the final four in the World Chess Cup (2007) before being defeated in the semi-finals by the eventual winner, Gata Kamsky. Carlsen's final placing in the 2007 World Cup qualified him for participation in the FIDE Grand Prix for 2008-09. Soon afterwards he tied for first place in the Baku Grand Prix (2008), the first round of FIDE's inaugural Grand Prix series. Carlsen later withdrew from the Grand Prix cycle despite his excellent result in Baku, complaining about "dramatic changes to ... regulations." and that “…changing the rules dramatically in the middle of a cycle is simply unacceptable.”

On the basis of his rating, Carlsen qualified for the Candidates Tournament that would determine the challenger to World Champion Viswanathan Anand in 2012. In November 2010, however, Carlsen announced he was withdrawing from the Candidates tournament. Carlsen described the 2008–12 cycle as not "...sufficiently modern and fair", and added that "Reigning champion privileges, the long (five year) span of the cycle, changes made during the cycle resulting in a new format (Candidates) that no World Champion has had to go through since Kasparov, puzzling ranking criteria as well as the shallow ceaseless match-after-match concept are all less than satisfactory in my opinion." Carlsen qualified for the World Championship Candidates (2013) that was played in London, again on the basis of his rating. He placed =1st with Vladimir Kramnik on 8.5/14 after both players lost their last round games, but as the first tiebreaker (score against each other in the tournament which was 1-1) failed to break the tie, he won on the 2nd tiebreak which stipulated that the player with the greater number of wins takes first place; he had scored 5 wins to Kramnik's 4.

Carlsen will now challenge World Champion Anand and the Anand-Carlsen World Championship (2013) will be played in Chennai in November 2013.

Classical Tournaments:

Carlsen earned his first IM norm in January 2003 at the Gausdal Troll Masters when he scored 7/10. His second IM norm came in June 2003 at the Salongernas IM-tournament in Stockholm where he scored 6/9 and his third IM norm came in the following month at the 2003 Politiken Cup in Copenhagen where he scored 8/11. In early 2004, Carlsen made a major international impact when he won Corus C with 10.5/13, easily winning his first grandmaster norm and earning his entry to the Corus B in 2005. Carlsen obtained his second grandmaster norm in the 3rd Aeroflot Festival (2004) in February and his third grandmaster norm at the sixth 6th Dubai Open (2004), held between 18th and 28th April.

Soon afterwards he placed 3rd at the 12th Sigeman & Co Chess Tournament (2004) followed later that month with a solid =3rd place at the Politiken Cup 2004, a half point behind the leaders Darmen Sadvakasov and compatriot Leif Erlend Johannessen. In October 2005, he won the Gausdal Bygger'n Masters in Norway with 8/9 ahead of 9 other grandmasters. He continued to improve in 2006, tying Alexander Motylev for first place in Corus Wijk aan Zee Group B (2006). After several more strong performances during the year, including 6.5/9 at the XXII Reykjavik Open (2006), =2nd at Bosna Sarajevo Tournament (2006), =2nd behind Sergei Shipov at the Midnight Sun Challenge at Breivika videregaende skole in Norway, =2nd at Biel Int'l Festival (2006) (after beating the winner Alexander Morozevich twice), first at the Gausdal Classics GM-A and a joint second-place finish at Linares-Morelia (2007), he crossed the 2700-mark, the youngest player ever to do so. A relatively poor result at Dortmund (2007) (3/7) was followed by a win at Biel Chess Festival (2007) (His score was equaled by Alexander Onischuk and so they played a tie-breaker match to determine the winner. After drawing two rapid and two blitz games, Carlsen won the Armageddon game) and a par for rating =2nd at the Arctic Chess Challenge (2007) where he scored 7/9, a half point behind the leader Alexander Moiseenko, and 3rd at the Tal Memorial (2007) in November 2007.

In 2008 Carlsen was the joint winner of Corus (2008) A-Group together with Levon Aronian, and placed second in Morelia-Linares (2008) behind Anand. He won clear first place at Aerosvit (2008) with a dominant 8/11 score. His "disappointing" third placement at 41st Biel International Chess Festival (2008) with 6/10, a half point behind joint winners Leinier Dominguez Perez and Evgeny Alekseev, was nevertheless still a 2740 performance, whilst his equal second in the Bilbao Grand Slam Chess Final (2008) with 5.0/10 was a 2768 performance. His relatively meagre 7/13 at Corus (2009) was followed by equal second placement behind Kramnik at Dortmund (2009) with a 2773 performance and 2nd with 5/9 at the M-Tel Masters (2009). The arrival of Garry Kasparov in 2009 as his coach enabled Carlsen's finest tournament performance to date, and one of the best tournament results in the history of chess. Carlsen eclipsed a stellar field consisting of Topalov, Peter Leko, Dmitry Jakovenko, Teimour Radjabov and Wang Yue to win clear first prize with 8/10 at the category XXI Pearl Spring Chess Tournament (2009). Carlsen's performance rating for the tournament was a record 3002 and lifted his FIDE rating in the November 2009 list to 2801, which made him only the fifth player to surpass 2800, and easily the youngest. After a slow start, Carlsen placed equal second with Vassily Ivanchuk behind Vladimir Kramnik in the Category XXI Tal Memorial (2009), which fielded ten of the world's top thirteen rated players. He saw out 2009 with a win at the London Chess Classic (2009), a point ahead of Kramnik, a result which pushed him to the top of the world ratings in January 2010.

2010 saw Carlsen's success continue, winning Corus (2010) outright with 8.5/13, half a point ahead of joint second placegetters Kramnik and Alexey Shirov. In June 2010, he won the category XXI King's Tournament (2010) in Bazna in Romania by a clear two points with 7.5/10 and a 2918 performance. Following mediocre performances at the 2010 Olympiad and the category XXII Bilbao Masters (2010), Carlsen returned to form by winning the category XXI Nanjing Pearl Spring Tournament (2010) outright with 7/10 (+4 -0 =6) and a 2901 rating performance, a full point ahead of World Champion Anand who took outright second with 6/10, and finishing the year by winning the London Chess Classic (2010) for the second time in succession. After a slow start in the Tata Steel (2011) super tournament, Carlsen finished =3rd with Levon Aronian behind Hikaru Nakamura and Anand with 8/13 and a performance rating of 2821. He followed up in June by winning the Bazna King's Tournament (2011) on tiebreak ahead of Karjakin, both finishing with 6.5/10, and by winning Biel Chess Festival (2011) in July with a round to spare and with a final score of 7/10 (TPR 2835). After another characteristically slow start, Carlsen placed =1st with Ivanchuk at the 4th Bilbao Masters (2011) with 15 points under the Bilbao scoring system (+3 -1 =6) and a 2842 performance rating, ultimately winning the tournament in a blitz tiebreaker. Then in November 2011, Carlsen won the Tal Memorial (2011) on tiebreak with 5.5/9 (+2 =7 -0 and a TPR of 2850) over Aronian. Carlsen finished 2011 with 3rd place at the category 20 London Chess Classic (2011) behind Kramnik and Nakamura, scoring +3 =5 (TPR of 2879). 2012 started with =2nd (+4 -1 =8; TPR 2830) behind Aronian and alongside Radjabov and Fabiano Caruana at the Category 21 Tata Steel (2012). He won the category 22 Tal Memorial (2012) outright with 5.5/9 (+2 =7) and a TPR of 2849. The month after his strong results in the World Blitz he finished outright second behind Wang Hao in the Grandmaster Tournament of the Biel Chess Festival (2012). In October 2012, Carlsen repeated his 2011 feat at Bilbao by winning the Bilbao Masters (2012) in a tiebreaker, this time against Caruana. He finished up 2012 by winning the London Chess Classic (2012), the third time he has done so, with a score of 6.5/8 (+5 =3 -0) and a TPR of 2994 (only fractionally below his record effort at Pearl Springs in 2009). London 2012 was also made historic for the fact that Carlsen's result lifted his January 2013 rating to a new record, exceeding Kasparov's record 2851 by 10 points.

Building on his achievements of 2012, Carlsen won the category 20 Tata Steel (2013) tournament with a round to spare, his final score being 10/13. He also set a new live rating record of 2874 after his round 12 win over Nakamura. He is currently playing in the Norway Chess Tournament (2013) being held in the Stavanger Region of Norway; in the preliminary Norway Chess Tournament (Blitz) (2013) held to determine the draw, he came 2nd with 6/9 behind Karjakin, thereby earning 5 games as White out of the 9 to be played.

Rapid:

Carlsen won the Glitnir Blitz Tournament in 2006 in Iceland. In September 2006 Carlsen placed 8th out of 16 participants at the World Blitz Championship (2006) in Rishon LeZion, Israel. In the blitz tournament associated with the Tal Memorial 2006, namely the Tal Blitz Cup, Carlsen scored 17½/34 points and placed 9th in a group of 18 participants. In March 2007, Carlsen played for the first time in the Melody Amber blind and rapid chess tournament in Monte Carlo. In the 11 rounds of the 16th Amber Tournament (Blindfold) (2007), he achieved eight draws and three losses (placing =9th) then scored three wins, seven draws and one loss in the 16th Amber Tournament (Rapid) (2007) (=2nd), for an overall 8th place in the combined tournament. In March 2008, Carlsen played for the second time in the Melody Amber blind and rapid chess tournament, which was held in Nice for the first time. Carlsen achieved four wins, four draws and two losses in the Amber Tournament (Blindfold) (2008), and three wins, two losses, and six draws in the Amber Tournament (Blindfold) (2008), resulting in a shared second place in the overall tournament.

In the Chess Classic Mainz (2008), Carlsen finished in second place after losing the final to defending champion Anand 3:1 (two losses, two draws). 2009 saw Carlsen score equal first in the Amber Tournament (Blindfold) (2009) with 7/11 alongside Kramnik and Aronian, and equal second with Veselin Topalov at M-Tel Masters (2009) behind Shirov with a 2822 performance. He also won the XXII Magistral Ciudad de Leon (2009), a rapid knockout tournament, ahead of Morozevich, Ivanchuk, and Wang Yue. Just a few days after his 2nd placement at the Tal Memorial (2009), he won the World Blitz Championship (2009) with 31/42, a full three points ahead of runner-up Anand. He shared first place at the 2010 Amber Rapid and Blindfold Tournament with Ivanchuk; scoring 6½ points in the blindfold and 8 points in the rapid, Carlsen accumulated 14½ from a possible 22 points. After a slow start in the Arctic Securities Chess Stars (2010) rapid tournament, he continued his success by defeating Anand in the two-game playoff for gold. In the World Blitz Championship (2010), held in Moscow on 16–18 November, Carlsen attempted to defend his 2009 title. With a score of 23½/38, he finished in third place behind Radjabov and the winner Aronian. After the tournament, Carlsen played a private 40-game blitz match against Hikaru Nakamura, winning with a score of 23½–16½. A phenomenal 9.5/11, 2.5 points clear of the field, in 20th Amber Tournament (Rapid) (2011) was insufficient for him to win the overall contest, as his results in the 20th Amber Tournament (Blindfold) (2011) were poor, resulting in a 2nd overall to 2008 and 2009 overall winner Aronian. In July 2012 he came clear 2nd in the World Rapid Championship (2012) behind Karjakin with 10.5/15, and clear 2nd in the World Blitz Championship (2012) with 19.5/30, half a point behind Alexander Grischuk.

Matches:

The DSB Bank match between Loek Van Wely and Magnus Carlsen took place 28th April - 1st May 2006. The four game classical time limit match was tied 2-2. Carlsen won the blitz portion of the match 3.5-0.5. He won a rapid match against Peter Leko held in Miskolc, Hungary, scoring 5:3 (+2 =6).

Team:

<Olympiad>: Carlsen represented Norway on board 1 in the 36th Olympiad (2004), the 37th Chess Olympiad (2006), the Olympiad (2008) and in the Chess Olympiad (2010). His best result was in the 2006 Olympiad, where he scored 6 points from 8 games and came 5th for board 1.

<National> He played board 1 for Norway at the European Team Chess Championships (2007) and won an individual silver medal.

<Club> Carlsen played four seasons in the European Club Cup. In 2001 and 2003 he played for Asker Norway on board 6 and board 1 (after he had gained his FM title) respectively, while his father Henrik was reserve on both occasions. In 2007 he played board 3 for OS Baden Baden, and in 2008 he played top board for MIKA Yerevan. His total game result from these 4 seasons was 15.5/27 (+11 -7 =9). He also played in the Norwegian Team Championship in 2002, 2003, 2005 and 2006, in the Bundesliga in the 2004-05, 2006-07, 2007/08, 2008-09 seasons, and in the Dutch Team Championship 2007.

In August 2006, he played in the NH Hotels event featuring the older Experience Team vs Youth team (easily won by the Youth team 28–22), and was equal top scorer with Alexander Beliavsky with 6.5/10.

Carlsen's 1 May 2013 FIDE ratings are:

  Rolfo: Well, some humor is good for everything. Here is a link to Humorous Norwegian Fairytales (the one with the porridge is no 9) http://oaks.nvg.org/lg4ra5.html

(don't be troll to each other..)

Mar-21-07  TheGladiator: <zarg>, I'm aware of that the S/N ratio doesn't get better by discussing meta stuff - I'm just amazed that for instance fxenderby, s4life, achieve and others defend behaviour which IMO clearly devalues this virtual room. Oh well, I won't add more to it at this point...

I have done some preliminal tests with the fritz/rybka slow/fast processor issue, btw. I soon realized that the 1.0 beta 32-bit is the only version still freely available of Rybka - I guess the playing strength is comparable to Rybka 1.1 (but this can probably be found out). 1.0 beta date back to December 2005.

I run two 30 game matches and one 10 game match (in total 70 games) between Fritz 8 and Rybka on my old stationary pentium 3 500 MHz PC, to find the settings where Rybka performed best compared to Fritz. I gave both engines the same opening book (tried both fritz8.ctg and TurkII.ctg, chose the much smaller TurkII with recommended settings for Rybka on both engines), an equally sized (small, 48 MB) hash table, and experimented somewhat with Rybka's search strategy (4 alternatives, from very positional to very tactical) to see what worked best against Fritz. The matches were played on one computer with ponder off.

The best settings I found for Rybka 1.0 beta, made it score roughly 67% against Fritz 8 on my 1999 hardware equipment, but it didn't get much lower with other settings either. So (as expected) even the 1.0 beta is clearly stronger (in the range of 100-130 rating points) than Fritz 8, everything else equal.

Then, to get some feeling for the proportions, I started playing some games between rybka 1.0 beta with settings as mentioned above, against the 32-bit version of fritz 5 (aka fritz 5.32) running on my semi-old Dell D600 laptop (1.6 GHz, plenty of RAM). The Fritzmark difference between this computer and the 500 MHz pentium III was roughly 3.5, rather close to the ratio of the CPU speed.

Fritz 5.32 didn't know how to make use of more than 255 MB for the hashtable (obviously, some programmer did a classic "oh a byte is big enough to hold the number of <foobars>" (here: megabytes of RAM someone could possibly spend on the hashtable) - so Fritz 5.32 got as much as it could take. I still used ponder off, so that "operator time" wouldn't influence anything (the operator being me - I didn't look into possible ways of connecting them directly). AFAIK fritz 5.32 was (naturally) a successor of fritz 5, but was released before fritz 6, which hit the market in late 1999. I don't know the relative strength between fritz 5.32 and fritz 8, but I assume the latter is generally stronger.

Anyway, since manually running a match on two computers take some time (no matter the time control), I've only completed four games so far, but I think I'll stop on 8. Even with just 3-4 times faster hardware, it seems that the difference of around 120 ratingpoints (or more, since I tested against fritz 8) between fritz 5.32 (1999) and rybka 1.0 beta (december 2005) has been compensated for. I need to play some more games to strengthen this hypothesis, but since I need a commercial Rybka to check current state of the art, I don't bother with too lengthy tests at this point.

4 points of "interest":

1) I probably won't have to brush the dust off my old 166 MHz pentium mmx box for this experiment, as I've also got my 3GHz Pentium 4 work PC ready if need be.

2) The score so far is 2 wins for fritz 5.32, one draw, and one win for rybka 1.0 beta.

3) The first win by fritz 5.32 was a clear example of rybka running into the horizon problem, but also an example of the potential problem with rybka's design choice of much more agressive pruning based on better heuristics - even on equal hardware fritz avoids this blunder significantly sooner than rybka (I'll post the position some other time.)

4) Rybka's win came in a position where fritz' heuristics just aren't good enough - even after ten minutes fritz sees no problems in the position and evaluates it as for itself, when rybka almost instantly (and correctly) understand that she is better.

Conclusion so far: I always enjoy it when "academic" algorithm theory taught at the university level proves to give very good intuition about things, without the need to know all "gory" details of neither concrete software implementations nor the latest achievements in hardware architecture ;)

You need to sample more often. This page is _always_ about the S-guy, at page 471 it's about him and Plato, at the page before that, it's about him and some other guys, at some other pages it's just about him.

If you want to blame me because I occasionally take a shot at returning this page to again being about chess and Magnus or some combination of the two, then fine. Entering, complaining and leaving, slamming the door, doesn't help much, either.

Mar-21-07  TheGladiator: For some reason I managed to write the nonsense word "preliminal" above when I meant "preliminary" ... Maybe I suddenly have gotten a problem with pronouncing 'r' as in "pleliminaly"?
Mar-21-07  TheGladiator: Hahaha... When searching for others doing the same mistake I did, I just found this in an article about Windows Media Player:

<after connection has been established (and possibly a few minutes of preliminal buffering)>

Preliminal buffering?!? :P "Please stop, the buffer is full" ... :D

Mar-21-07  slomarko: funny you state you want this page to be about Magnus just after you've posted two totaly Magnus unrelated posts.
Mar-21-07  Plato: Any problems with preliminal buffering are clearly the result of WMP's acute aggressivity. Hope that helps.
Mar-21-07  TheGladiator: <Plato> I suppose you're right, but personally I haven't experienced any of the problems you refer to...

  JointheArmy: <slomarko> <I might have said that indirectly, somebody asked what do you think about his play there and I said he has played very well. maybe it was on another page even I dont remember. I've to say i found this "who said what" a little ridiculous. When you go with your friends to the bar and talk about football do you quote what somebody said months later? Chess should be fun and everybody should have the right to express their opinion.>

Then I'm sure you'll be glad to point out your past compliments on other pages and your "indirect" compliments to Carlsen. Oh wait, you said you "might" have said that. Whatever that means.

Or I can do that for you by searching 30 pages of "slomarko carlsen". Unless of course you refered to Carlsen "indirectly" namely "this kid" or "Wonderboy". In that case the ball is in your court. Mind you, I'll be waiting.

Mar-22-07  SirBruce: According to the games in chessgames database, Aronian's record against Carlsen is +3 -0 =8.

  Rolfo: No doubt, Aronian is the stronger for the time being
Mar-22-07  Progman: I'd be extremely surprised if Carlsen beats Aronian in the upcoming candidate's.

I'll root for Anand this time! Carlsen, Karjakin and Negi will get their chances in due time.

Mar-22-07  Fincher: <Progman: I'd be extremely surprised if Carlsen beats Aronian in the upcoming candidate's.> exstremely?? lets say its 47/53 like AK off suit against 66 in tex holdm :)
Mar-22-07  TheGladiator: <SirBruce: According to the games in chessgames database, Aronian's record against Carlsen is +3 -0 =8.>

Aronian's got 1 blinfold win (Amber this year - probably drawn ending where Magnus failed to hold), 1 rapid win (WCC Libya 2004 - theoretically drawn ending, where Magnus short of time misplayed it) and one classical win (Tal Memorial, where Magnus made an unbelievable blunder in a theoretically drawn ending).

So, of course an edge for Aronian, and all three wins have something in common (probably drawn endings where Magnus went wrong). Magnus still hasn't won a game against Aronian in 11 tries, but he came close in Morelia, so I think the candidates would be a good occation for the first one :)

The good thing, though, is that so far there have been no opening catastrophies against Aronian, and Magnus has got a worse record (at least in terms of the actual games) against other players, so I'm fairly optimistical; Magnus has got real chances in the candidate matches, despite Aronian being the favourite.

But i agree there are chances, in fact all candidates matches are pretty even in my opinion, one blunder could decide...
Mar-22-07  Solon: When is the match against Aronian? And where?
Mar-22-07  slomarko: A draw in the game against Leko, it was very confusing game and it ended... you know how.
Mar-22-07  s4life: <Plato: Any problems with preliminal buffering are clearly the result of WMP's acute <aggressivity>.>

Where is danielpi?! I want another 20 or 30 pages of grammatical rambling! j/k.

<Gladiator> It's good the discussion moved on.. I like to play the devil's advocate sometimes.. I feel <slomarko> is in general, a nice fellow who seldom attacks personally other people (it's more than what I can say about me or you actually)... regardless, he's narrow minded about certain things but so is everyone to a certain degree, the difference is that he speaks his mind without fear of retaliation. That's all I have to say on the subject.

Mar-22-07  slomarko: unbelievible mistake by Carlsen in his rapid game against Leko. in the following position:

Carlsen played 16...Qh1?? Instead winning on the spot was the simple 16...Qg4 17.Kf2 Qh4 18.Ke2 Bg4 19.Kd2 Bb4 and white losses the queen!

Mar-22-07  TheGladiator: It was really strange that Magnus didn't play 16...Qg4+, the crazy blindfold game (where both were winning a couple of times) must've taken its toll on the players.

But having Leko swimming around like he did after 14 moves as white - _that_ is really something, wasn't that just amazing, Slomarko? Not seeing the eternally beautiful 14... Qe8!! is more natural, but it takes a genious to create a position where moves like Qd8 are possible. Right, Slomarko?

Some crazy stuff between Magnus and Leko today...

Mar-22-07  slomarko: <Not seeing the eternally beautiful 14... Qe8!! is more natural, but it takes a genious to create a position where moves like Qd8 are possible. Right, Slomarko?> Thats one possible explanation. another is that Leko has missplayed the opening horribly. Add to that he was trying to play "out of character". (slow maneuvering is his game not tactical complications).
Mar-22-07  Progman: That game had deserved an ending like Qg4. Up until then, it was pure beauty by Carlsen.
