[Baskaran, Adhiban]
1.c4 g6 Black wants the option to go Kings-Indian, while also keeping all her other options flexible. 2.g3 Bg7 3.Bg2 c5 Looks like this was Judit's intention, to aim for the Symmetrical English. 4.Nc3 Nc6 5.Nf3 b6!? An interesting line with the intention to do double fianchetto. 6.0-0 Bb7 7.d3 Luke is trying to keep it simple. [White could try to prepare d4 with 7.e3 Arguably this is White's most challenging attempt to fight for an advantage. 7...Nf6 8.d4 Na5 9.Qe2 0-0 10.Rd1² White was slightly better and went on to win in  (Portisch-Keene Moscow 1977)] 7...Nf6 [Another way to develop the knight is 7...Nh6 8.Bd2 Nf5 The knight is looking very proud on f5, helping to control the d4-square. 9.Rb1 0-0 10.a3 d6 11.b4 Qd7 Black had fully equalized and soon drew the game in (Gulko-Miles Las Palmas 1996)] 8.Bg5 I really don't understand the point of this move. 8...h6 9.Bd2 Not the best idea... [It was better to give up the bishop pair and prepare d4. 9.Bxf6 Bxf6 10.e3 0-0 11.d4 e6! Fighting for the center control. 12.Ne4 cxd4 13.Nxf6+ Qxf6 14.exd4 Ne7 with an equal game.] 9...d5 Black has already achieved a slight edge. 10.Qc1 I guess this is the point :), to stop Black from castling. [10.cxd5 Nxd5 11.Nxd5 Qxd5 12.Bc3 0-0 Black is more preferable due to the extra space and potential outpost on d4 for the knight.] 10...Rc8 Judit just continues developing her forces and slowly is starting to indirectly put pressure on the queen via the c-file. 11.Rb1 [The other option was 11.e4 dxc4 12.dxc4 Qd3³ Black is also better here.] 11...Qd7 12.b3 d4 Gaining more space and dominating the knight. 13.Nb5 h5! Now Luke might have been wishing that he should have just allowed Judit to castle :). 14.b4 cxb4 15.Bxb4 a6 The knight is not at all sure what he should be doing in this game :). 16.Na3 Nxb4 17.Rxb4 Nd5 Black is just cruising towards a big advantage, the deep plan behind Judit's Rc8 is now seen! 18.Rb3 Nc3µ 19.Qd2 Bxf3 [Stronger was 19...Na4! Protecting the only weakness on b6 and then continuing the kingside assault with h4.] 20.Bxf3 h4 21.g4 This looks the lesser of the evil, otherwise Black might create a mating attack along the h-file. 21...b5 Now the b6-pawn which was originally a weakness is turned into a strength! 22.h3 0-0 23.cxb5 axb5 White's position is very depressing and the knight on c3 is a monster and cuts into White's activity. 24.Nc2 Rc5 25.Ne1 Bf6 The bishop will be nicely placed on g5. 26.Ng2 Bg5 27.Qb2 Rfc8 28.Kh1 It is hard to give White any good advice here. 28...Qd6 29.Ra3 Na4! and suddenly it becomes clear that White's funny piece setup on the kingside only allows a back rank mate type finish :). 30.Rxa4 bxa4 The rest is simple. 31.Ne1 Rc1 32.Qb7 Rb8 33.Qa7 Bd2 I think this line with b6 which Judit played could be an interesting direction for Black and also it was very instructive to see how she slowly built up her position and demolished White's defenses. 0-1.
The main file is good for 1226 entries where a small 28 of them are more than excellent analysed,again a fine example: Fedoseev,Vladimir1 (2696) - Carlsen,Magnus (2847) [E60]

[Giri, Anish]

1.d4 Nf6 2.c4 g6 3.h4!? Magnus has chosen the Grunfeld (or, less likely, a King's Indian) and Vladimir in his turn also shows readiness for a full fledged fight. White has a ton of safer options, but no guts no glory and so 3.h4!? was essayed. The system has been somewhat of a joke for a while, continued to be so after Topalov did it against me in what has been a terrible Candidates tournament for him in 2016, but it was only after Grischuk has reintroduced it in the Grand Prix 2019, when people have realized that it is there to stay. The computers are surprisingly optimistic for White in the ensueing lines, but at the same time, Black does have a choice between a good King's Indian, a good Volga and a good Benoni. 3...Bg7 4.Nc3 d6 5.e4 Nc6!? A cunning move order by Magnus, played after some thought. It is likely he was choosing from the plenty of options Black has at his disposal. The idea of Nc6 this early is that Black is ready to strike with e5, while the usual d4-d5 push is slightly less of an issue, as we will later see. 6.d5 Principled, but developing the g1 knight first is also sensible. 6.Nge2 happened in Shankland-Svidler, which ended Peter's tournament after he lost a complex game, but Vladimir has chosen another path, which seems critical as well. 6...Ne5! The point. The knight sits extremely well on this square, thanks to the far advanced h-pawn. Now f4 will always be met with Neg4. Note that this wouldn't be the case if white had the h2-h3! push, or if you could move pawns backwards in chess. 7.Be2 h5 8.Bf4?! In a position as complex as this one, every move is very critical and the smallest nuances can have serious impact. This feels very normal, but since White has no better next move than Nf3 anyway, he should have started with that instead and chosen a better destiny for the bishop later. [8.Nf3 is just a smarter move order in any case. 8...Nxf3+ 9.gxf3 0-0 and now that the pawn structure has clarified, it is easier to pick a good square for the c1 bishop. Placing it in front of the mobile f3 pawn looks unharmonious and instead Bg5 or Be3 is clearly to be preferred. As I understand such pawn structures, the position revolves around the f4-f5 push which White wants to time well. It isn't going to be easy, with Black having c6 break, followed by another break eventually, be it e6 or f5, or perhaps a queenside expansion with b5. White has a strong pawn center, but no clear shelter for his king, even in the long term.] 8...0-0 9.Nf3 What else, but now the placement of the dark squared bishop is very questionable. 9...Nxf3+ 10.gxf3 c6 it is good to get c6 and cxd5 trade in, to have the c-file open, better control over the b5 square and some room for the d8 queen to play with. 11.Qd2 cxd5 12.cxd5 Kh7 Classy. The kingside is now just a little bit more tight, the h6 square guarded and if Black pushes f5 the soft g6 pawn is guarded, which can gain Black time. 13.a4?! Often when you try preventing counterplay on the side where you are weaker, you only delay the inevitable and weaken urself further. Black was eventually going to push b5, likely, but the cure is worse than the disease, and now the b3 square is weakened and when b5 will eventually happen, Black will have more files and diagonals open for his queenside play. 13...Nd7 14.a5 White gains some space, but it is not very useful and Black can already start considering b5 push, with or even without the preparatory a7-a6. 14...f5! Magnus hits on the kingside first. The weakened g6 pawn is out of reach, while Black's pressure along the f-file is the primary factor here. 15.Ra3 Ne5 [15...b5!? was very timed here, as well and after the game, Magnus has mentioned this motif as well.] 16.Be3?! The bishop moves to a more harmonious square, not in the way of the f3 pawn, but this allows a strong positional pawn sacrifice. 16...f4! Black gives up the f-pawn, but gains ultimate control over the f4 square, which is crucial, as that will guarantee the eternal outpost for the monster knight on e5. 17.Bxf4 Bd7 Setting up a beautiful positional exchange sacrifice. Instead, there was a more laconic solution to the problem of the f4 square. [17...Rf7!? is less spectacular than what Magnus has done in the game, but at the very least just as effective. Qf8 is a huge threat, and White has no better option than to give up the f4 bishop for the knight, giving Black the ultimate dark square control at the cost of just one pawn.] 18.Nd1 White guards f3 and is ready to move the f4 bishop. Obviously Magnus has anticipated exactly this. 18...Rxf4! Beautiful and even though objectively the computers say the position is around equal, it was very clear to me, that Black will be having all the fun from now on. The evaluation of the computer is meant to estimate the computer's own chances in a game against itself, which doesn't always correspond to how the chances between the two human players are actually split. 19.Qxf4 Bh6 20.Qg3 Qf8! Gaining control over the f4 square- the whole point of the sacrifice. 21.Ne3 Bf4 22.Qg2 Rc8 Rooks are meant for open files. 23.Rc3 Trading the potentially active c8 rook is very sensible. The engine offers the bold Rb3!? as an alternative, estimating the position as around level, but it is pretty scary to just ignore Rc1+. 23...Rxc3 24.bxc3 Qc8 Now the queen switches to the queenside. White's pieces are in disharmony, though from a point of view of defense, he does still have a very solid, although depressing, setup. 25.c4 b5!? Opening files and keeping the Bh3 idea, in case White castles short. 26.axb6 This is called en passant, noobs. :) 26...axb6 27.Qg1?? White basically needs to get the king to the right, so the rook can go to the left. Here he is preparing Kf1-Kg2, but he is just not in time. [27.Kf1! first would achieve the goal of regrouping the pieces the right way. White can follow it up with Kg1 Qf1 if needed, or Qg1 Kg2, depending on the situation. 27...b5 This wins Black an important pawn, but White can defend if he continues with the right plan. 28.Qg1! bxc4 29.Kg2! Qc5 30.Qa1 White just has to make sure the h1 rook gets to participate. 30...Bxe3 31.fxe3 Qxe3 32.Re1 and surprisingly White is actually alive. He has given up a bunch of pawns, but got some coordination and with Qc1 incoming Black's active queen will have to give up some ground.;
27.0-0!? would in my opinion be a very practical way to try and setup a defense. The rook is now directly ready to get into the game and if Black chooses to take it, which he should, then the position simplifies a lot and the drawing tendencies rise. 27...Bh3 28.Qh1 Bxf1 29.Kxf1 Black can just take on e3 and regain the c4 pawn as well, but that will mean that the material balance is only restored and if Black cashes out all of his positional compensation back into material, we are likely see the game end peacefully.] 27...Qa8! 28.Kf1 Qa2! The key. Stopping the much needed Kg2 move, which would release White's heavy pieces that are stuck in the cage. Now all of a sudden white is totally paralyzed. 29.Ng2 Qa1+ this works out more than perfectly, but objectively the clean win was starting with 29...Qb1!+ [29...Qb1+! 30.Ne1 b5! well timed shot. Computers always do that well. 31.cxb5 Bxb5 and Black keeps White stuck, as 32.Bxb5? loses to Nxf3+! intermezzo. White doesn't have a move here and is just lost.] 30.Ne1 Qb2 The queen is methodically coming closer. Fedoseev had his last chance here. 31.Ng2? Playing along, but White can't afford that any longer. [31.Nd3! barely looks more fun, trading the only piece that can actually attack something, ever, but at the same time, this would rid Black of some horsepower, pun intended. 31...Nxd3 32.Bxd3 Qc3 33.Be2 Qc2 White is almost in zugzwang. 34.Rh2! But almost. Without the knights, Black actually doesn't have a clear way to win, as White just stands, but at the same time, to say that White is fine here, would be a gross exaggeration.] 31...Qc1+ 32.Ne1 Qd2 now White is truly stuck, as 33.Ng2 is losing to Nd3!. White now has to shuffles his queen and rook, inside a cage, waiting for the finishing blow, that Black inevitably will come up with. e6 is a resource to soften up white's pawn formation in the center and in the long run, the e5 knight is also free to roam around. 33.Qg2 Kg7 34.Rg1 Kf8!? taking the time and moving away from any Nd3 Nxd3 Qxg6 tricks. 35.Qh1 e6! Gains Black some extra squares. 36.Rg3 exd5 37.exd5 Bf5 The bishop is better placed here and the e5 knight is now free to embark on a finishing journey. 38.Rg1 Kf7 39.Rg3 Nd7 40.Rg5 Bxg5! In a dominating position, it is very important, at some point to just start cashing it out. The rook can and should be picked up now. 41.hxg5 Ne5 the threat was stronger than the excecution and White is just dead lost here. White has to move his queen and then Qc1 will create a deadly threat of Nd3. White has resigned. His position is helpless and he has been demolished and demoralized, but as it is often the case in chess, it didn't have to happen (28.0-0!/28.Kf1!). It did though. 0-1.
