Candidates Round 4: Draws

by Carlos Alberto Colodro
3/21/2020 – All games of round four at the Candidates Tournament in Yekaterinburg finished peacefully, which means Wang Hao, Ian Nepomniachtchi and Maxime Vachier-Lagrave are still sharing the lead on 2½ out of 4. Caruana pushed his h-pawn against Nepomniachtchi's Grünfeld but could not convert his slight advantage, while Grischuk entered his usual excessive time trouble while defending a complicated position against Vachier-Lagrave — in the end, he managed to hold the balance.

Professionalism 

The eight-player Candidates tournament is one of the most prestigious global chess events, held every two years. The event will determine who will challenge the defender Magnus Carlsen for the title of the World Chess Champion. This year’s event has a prize fund of 500,000 Euros, which is the highest ever in the history of the Candidates tournaments.


All the results from round four:

Name Result Name
Caruana Fabiano ½ - ½ Nepomniachtchi Ian
Wang Hao ½ - ½ Alekseenko Kirill
Vachier-Lagrave Maxime ½ - ½ Grischuk Alexander
Ding Liren ½ - ½ Giri Anish

Round five takes place on Sunday, March 22 at 4:00 p.m. local time. Pairings:

Name Result Name
Giri Anish   Caruana Fabiano
Grischuk Alexander   Ding Liren
Alekseenko Kirill   Vachier-Lagrave Maxime
Nepomniachtchi Ian   Wang Hao

The players returned to the action after the first rest day in Yekaterinburg, and showed the kind of professional preparation and levelheadedness that allowed them to reach — and remain at — the elite. All four games were drawn, leaving Wang Hao, Ian Nepomniachtchi and Maxime Vachier-Lagrave atop the standings table on 'plus one'.

The fact that there were no decisive results does not mean the games lacked content. Caruana used a critical approach against the Grünfeld and only stopped putting pressure on his opponent when he chose the wrong queen manoeuvre in the endgame; Giri played for counterchances with Black against Ding Liren, but could not make much of it; Alekseenko surprised Wang Hao in the opening, prompting his opponent to play solidly; while Grischuk spent almost one hour on his 18th move only to find out 'MVL' had calculated a different line than the one he had spent so much time on.

Vachier-Lagrave ½:½ Grischuk

Grischuk chose the Berlin Defence for a second time in Yekaterinburg in as many games with Black. Compared to his round-two encounter against Nepomniachtchi, however, this outing was markedly less successful, as he had to work hard to neutralize Vachier-Lagrave's strong initiative. In customary fashion, he spent close to an hour on move 18:

 
Vachier-Lagrave vs. Grischuk
Position after 18.fxg3

After 53 long minutes, Grischuk played 18...e7. Curiously, he later confessed that he was 100% sure (not even 99% sure, he emphasized) that Vachier-Lagrave would respond with 19.g4, so when the French grandmaster went 19.h4 instead, he had simply wasted an hour.

With the time control dangerously approaching, White was the one calling the shots, but 'MVL' missed a big chance on move 30:

 
Position after 29...Nxa4

White gave a check with 30.a3+, leaving behind the perfect moment to play 30.♖e4 when, according to GM Daniel Fernandez (see his full annotations below), "White had a win which will doubtless go down in the calculation books for decades to come". After this critical point, Grischuk's defensive manoeuvres were sufficient to hold the balance, despite playing almost exclusively on increments. The draw was signed on move 53. Vachier-Lagrave was visibly unsatisfied with the outcome:

I am unhappy with the result because I felt I had a very dangerous initiative. [...] To be completely fair, I didn't see a clear win for me and it's possible that Sasha just defended very well.

1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8 9.h3 Ke8 10.Nc3 h5 11.Bf4 Be7 12.Rad1 Be6 13.Ng5 Rh6 14.Rfe1 This is the critical move, setting up an existential problem for Black: if the bishop on e6 moves, White can play e6; if he goes ...Rg6 then White gains time to push kingside pawns, and if he does not cut the kingside Gordian knot then he has more pieces tied up there than White does. The main plan in response to all this is ...h4, but not immediately. 14.g3 Bxg5 15.Bxg5 Rg6 16.Bf4 Nh4= Fedorchuk,S-Malakhov,V Brest 2018 14...Bb4 Before granting White a mobile kingside majority Black makes sure that the balance of queenside structures favours him. 14...h4 15.Re4 Rd8 16.Rxd8+ Bxd8 17.Ra4 a6 18.Nce4 Bc8 19.Nf3 Rh8 20.Bg5 Bxg5 21.Nexg5 Ke7 22.Rf4 c5 23.Kh2 b6 24.g4 hxg3+ 25.fxg3 Nh6 26.Re4 Bb7 27.Re2 a5 28.Nh4 Rd8 29.g4 Ba6 30.Rf2 Motylev,A-Bacrot,E Shamkir 2014 15.a3 Bxc3 16.bxc3 h4 Up to this moment both players have been following Grischuk's round 2 game, of which the opening phase was rather in his favour. 17.g4!? 17.Kh2 Kf8! Black initiates a standard plan. The king must be evacuated so that the rook can get to e8, which in turn frees up the e6-bishop to move without the pawn thrust e6 being necessarily an issue. 18.Rb1 b6 19.Rb4 Re8 20.Ra4 a5 21.Bd2 c5 22.Rf4 Rh5 23.Rf3 Kg8 24.Bc1 Ne7 25.g4 hxg3+ 26.fxg3 Nc6 White has more or less played without an idea here and the central pressure he usually gets in return for the fractured queenside structure is not materializing. Nepomniachtchi,I -Grischuk,A Yekaterinburg 2020 17...hxg3 18.fxg3 Ne7 Also perfectly possible and a bit more principled is: 18...Rd8 19.Rxd8+ Kxd8 20.g4 Ne7= 19.h4 Nd5 20.Bc1 Probably this is still preparation (!) but how worried need Black be? Nxc3!? Black takes the bait! 20...Rd8= 21.Rd3 Na4 22.Rf3 Clearly this was White's intention. Black needs to respond incisively to the doubling on the f-file. Bd5 23.Rf4 23.Rf5 Rh8 24.Ref1 Rf8= 23...Nb6 24.Ref1 Rg6 25.Rf5 Bc4 26.Re1 White intends h5 and there are various ideas of a4, Re4 and so on that he can use too. His compensation is not in doubt. I wondered for a while whether some kind of 'perpetual rook' draw was on the cards, but after 26.R1f3? Black probably responds simply with Rd8! activating the second rook, and White's compensation begins to look really doubtful. 26...Ke7 27.h5 27.e6!? At first the engines like this move, but it's nothing special compared to the more solid text. f6 28.h5 Rh6 29.Ne4 Rh7 29...Rhh8 30.h6 Rag8 31.hxg7 Rxg7 32.Rxf6 Rgh7∞ 27...Rh6 28.g4 Now the position has reached peak complexity and both sides understandably begin making mistakes. Rhh8?! Black opts for a move which is 'safe', but still wrong. 28...Be6! 29.Nxe6 Rxe6 30.Bg5+ Kf8 31.Ref1 Kg8 32.Rxf7 Nd5= Black has fair winning chances in this position too, because White often finds himself a pawn down. 29.a4!? 29.e6! f6 30.a4! It is very far from clear that this order is any better for White. Why would you voluntarily deprive yourself of Rxf7+ in all the lines? But the engine is impossible to argue with. fxg5 31.Ba3+ Ke8 32.Rxg5 Rh7 33.Rf5 Rh8 34.Rf7 White has a massive attack, and Black's time-pressure (in no small part caused by spending 43 minutes on move 18) compounds the problems. 29...Nxa4?? 29...Be6 30.Ba3+ Ke8 31.Rf4 Nd5 32.Nxe6 fxe6 33.Rf3 30.Ba3+?! White had a win which will doubtless go down in the calculation books for decades to come. 30.Re4! Be6 30...Nb6 31.Ba3+ 31.Rxc4 Nxc4 32.Rxf7+ Ke8 33.Rxc7 is also possible, but a long way from being decisive. 31...Ke8 32.Nxf7! This is the least intuitive part of the whole sequence and so I assume it is this MVL missed. Bxf7?! 33.e6+- 31.Nxe6 fxe6 31...Nc3 32.Ng5 Nxe4 33.Rxf7+ Ke8 34.Rxg7+- Black has managed to exchange one of the attackers but the remaining two, plus the passed pawns, are too much. 32.Bg5+! 32.Ba3+ c5 32...Ke8 33.Rf3! Specifically this move, so that Black's knight can't get to c3 and then d5. Nb6 34.Ref4 Nd5 35.Rf7 b5 36.Rxg7+- 30...c5 31.e6 f6 32.Bxc5+ Nxc5 33.Rxc5 fxg5?! White gets a little nibble after this, though the game never leaves the drawing margin. 33...Rhc8!= 34.Rxc7+ Kd6 34...Kf6?? 35.Rf7#! is mate. 34...Kf8!? 35.Rxc4 a5 seems a touch more solid; White has no way to press meaningfully despite a number of lines where he retains an extra pawn. 35.Rxc4 a5 36.Rd1+ 36.Rd4+!? Kc6 37.Red1 Rhe8 37...a4 38.Rc4+ Kb5 39.Rc7± 38.Rc4+ Kb5 39.Rc7 Rxe6 Black should probably draw this, but there are various ways to pose problems. 36...Ke7 37.Re4 Rhd8 38.Rb1 Rdb8 39.Rb5 a4 40.Rxg5 Rg8 40...a3? 41.Rxg7+ Kf6 42.Rf7+ Kg5 43.Rf5+ Kh6 44.Rf1± sees White make it back to a1 in time. 41.h6 gxh6 42.Rxg8 Rxg8 43.Rxa4 h5! Making sure that there are no more tricks based on White's rook being marginally more active. 44.Kf2 Rxg4 45.Rxg4 hxg4 46.Kg3 Kxe6 47.Kxg4 Ke5 48.Kf3 Kd4 49.Ke2 Kc3 50.Kd1 b5 51.Kc1 b4 52.Kb1 b3 53.cxb3 Kxb3 ½–½

Caruana ½:½ Nepomniachtchi

The theoretical experts followed 19 moves of a 1987 encounter between living legends Vlastimil Hort and Maia Chiburdanidze out of a Grünfeld Defence! By then, however, it was clear that Caruana had the ideas fresher in his mind, as Nepomniachtchi himself pointed out. Caruana pushed his h-pawn all the way down to the sixth rank and started exerting pressure on his opponent.

In the midst of an ending with queens and dark-squared bishops, the American let his advantage slip away by placing his queen on the wrong square:

 
Caruana vs. Nepomniachtchi
Position after 30...Kf8

'Nepo' called White's 31.f3 'very clever', as it wants to provoke 31...f5, when 32.♕d1 improves White's chances. The problem with the move is that it allows the intermediate 31...e1+ and after 32.g2 Black can safely go 32...f5. In the diagrammed position, 31.♕d4 would have maintained the status quo, giving Caruana more chances to keep torturing his opponent.

Naturally, 'Nepo' was satisfied with the draw. When asked about his preferred activities to relax during the rest days, the Russian quipped:

The ideal routine is to check Anish's Instagram or Twitter to find [some] wisdom and then to learn it. Then, of course, every time I see no updates from him I'm very disappointed.

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 In the previous round Giri opted for 5.Bd2 and obtained a slight edge after MVL responded in unorthodox fashion. 5...Nxc3 6.bxc3 Bg7 7.Bc4 c5 8.Ne2 0-0 The text move is the majority choice but Black can also try and head for an endgame. 8...Nc6 9.Be3 cxd4 10.cxd4 Now this is the same structure as the Semi-Tarrasch and play evolves quite similarly. Qa5+ 11.Bd2! It is less advisable to play along: 11.Qd2 0-0 12.Rd1 Bd7 13.0-0 Qxd2! Only now, when White can't recapture with the king. 14.Rxd2 Rac8 15.Rb1 Na5 16.Bd3 b6 17.Rb4 e6 Lagarde,M-Vachier Lagrave,M chess.com 2019 11...Qd8 11...Qh5!? 12.Bc3 12.d5 Ne5 13.Bc3 Bd7 14.Bb3 Rc8 15.Rc1 Qb6 16.Ba4 0-0 17.Bxd7 Nxd7 18.Bxg7 Kxg7 19.0-0 White probably has a very small advantage here,Topalov,V-Mamedyarov,S Heraklio 2007 12...0-0 13.0-0 13.Qd2 Bd7 14.0-0 Rc8 15.Rfc1 a6 16.a4 Na7 17.Bd3 b5!? led to a chaotic game in Ivanchuk,V-Mamedyarov,S Wijk aan Zee 2008 13...Bd7 14.Rb1 b6 15.Qd2 Rc8 16.Rbc1 e6 17.h3 Le,Q-Mamedyarov,S Khanty-Mansiysk 2013 9.0-0 Nc6 10.Be3 b6 11.Qd2 White declines to take the pawn and makes one of several sensible moves. It doesn't, however, restrict Black from making any of the moves he might like on general grounds (...Qc7, ...Bb7 or ...e6.) 11.dxc5 Qc7 This is a major theoretical line where surely Black had done enough research to hold his own. It is a specialty of MVL from both sides of the board. 12.Nd4 12.f4 bxc5 13.Rb1 Rd8 14.Qa4 Na5 Carlsen, M-Svidler, P Moscow 2011 12...Ne5 13.Nb5 Qb8 14.Be2 When MVL was White he chose: 14.Bd5 Ng4 15.g3 Nxe3 16.fxe3 a6 17.Bxf7+!? Kh8 18.Nd4 18.Bd5 Rxf1+ 19.Qxf1 axb5 20.Bxa8 Qxa8 21.cxb6 Qc6= 18...bxc5 19.Bd5 Rxf1+ 20.Qxf1 cxd4 21.Rb1 Qa7= Vachier Lagrave,M-Gelfand,B Tromsoe 2013 14...bxc5 14...a6!? 15.Na3 bxc5 16.Bxc5 Qc7 17.Bd4 Rd8 18.Qc1 Ng4 19.Bxg4 Bxg4 20.Qe3 Rab8= Bacrot, E - Vachier-Lagrave, M Biel 2013 15.Rb1!? Now theory continues for a great many more moves, and I would refer you to the coverage by Glenn Flear on ChessPublishing. 15.f4 Ng4 16.Bxc5 a6 17.Na3 Qc7 18.Bd4 e5 19.fxe5 Nxe5 Black's compensation here has been demonstrated repeatedly, e.g. So,W-Vachier Lagrave,M Wijk aan Zee 2015 15.Bxc5 a6 16.Nd4 Qc7 17.Nb3 a5 18.Bd4 a4 19.Nc5 Rd8 20.Qc1 Ng4 Yakubboev,N-Le Quang Liem Sharjah 2019 11.f3!? Bb7 12.Qd2 Rc8 13.Rac1 e6 14.Rfd1 cxd4 15.cxd4 Qd6 The familiar semi-Tarrasch structure ultimately worked in Black's favour in Gaifullin,A -Kokarev,D Sochi 2017. All of the major piece deployments end up being 'much of a muchness'. One of the more independent ideas is 11.Rc1 Bb7 12.d5 , but Black may react with Ne5 13.Bb3 f5!?∞ 11.Rb1!? Qc7 12.Bf4 e5 13.Bg3 Qe7 14.Bd5 Bb7 15.Qa4 Na5 16.Bxb7 Nxb7= Xu Yinglun - Xu Minghui, Harbin 2016 11...Bb7 12.Rfd1 12.Bh6?! Bxh6 13.Qxh6 cxd4 Even defending the e4-pawn first may not be good enough: 12.Rad1 Rc8 13.Bh6 cxd4 14.cxd4 Bxh6 15.Qxh6 Nb4! and White still has some tactical issues. 12...cxd4 12...Rc8!? is also playable and marginally less committal. 13.cxd4 Rc8 14.Rac1 Na5 15.Bd3 Qd7 16.h4 White wants to keep pieces on. 16.Bh6 Rxc1 17.Rxc1 Rc8 18.Rxc8+ Bxc8 19.Bxg7 Kxg7 20.Qc3 Qc6 21.f3 Qxc3 22.Nxc3 Nc6 23.d5 Nb4 24.Bb1 Bd7 25.Kf2 e5 26.Ke3 f6 Typical of Black's strategy here was the encounter Molina,R-Fusco,L Santos 2011: the pawns on dark squares form an impenetrable barricade, and by trying something like f4 White will only risk losing. 16...Rxc1 With a series of individually fine, but collectively slightly compliant moves, Ian drifts into a worse position. The slightly feistier 16...e5 17.d5 f5∞ was also possible. 17.Rxc1 Rc8 18.h5 White gets to establish his 'alpha-zero' pawn on h6. As a corollary of this, he must keep queens on, or the pawn is more likely than not to end up a weakness. Rxc1+ 19.Qxc1 Qc8 20.h6 The (conventional) computer doesn't really understand why this is a big deal, but in about 10 moves the lines start favouring White for deep reasons related to mates on g7! Bf8 21.d5 e6 A small exception to the last comment: after 21...Qxc1+ 22.Bxc1 Black isn't really in a position to mobilise his bishop on f8, and so it is White who probably has slightly better chances. f6 22...e6 23.dxe6 fxe6 23.Nd4 Bc8 Particularly worrying would be 23...g5 24.Nf5 Bc8 25.e5! Bxf5 26.Bxf5 Bxh6 27.e6± when Black might draw but White definitely has more than enough compensation for a pawn. 24.Bd2 22.Nc3 Nc4?! Weirdly, I think this trade is a bit counter-productive for Black. Scenarios now arise where the trade of dark-squared bishops would be nothing short of fatal for him. 22...Ba6! 23.Qd1 Bxd3 24.Qxd3 Nc4 25.dxe6 fxe6= 23.Bxc4 Qxc4 24.Qd2 exd5 25.Nxd5 Bxd5 26.exd5 Caruana is conducting this phase of the game very well; the central passed pawn and the constant thorn in Black's side on h6 combine to give him excellent winning chances provided he stays calm. Qb4 27.Qd3 Qa3 28.Qc2!? White probably recognised the strength of placing his queen behind the d-pawn but then tried to finesse it. 28.Qd1! The idea of this move is simply to play Bf4 and push the d-pawn. A trade of dark-squared bishops would not be good for Black here. Qd6 28...Bd6 29.Qd4! Bf8 30.Bf4 Qb4 31.Qe5 Qb1+ 32.Kh2 Qxa2 33.f3+- Clearing the f-file enables White to threaten Qf6 followed by Be5. There is practically no defense. 29.g3 f6 30.Bf4 Qd7 Black's position is not yet so bad, but it's clear White has made progress. 28...Qa5 29.Qd1 Now Black can't play ...Qd6, and pushing d6 is a real threat, but there's a rather simple answer. Bd6 30.g3 30.Qd4?? would now get mated: Qe1# and this fact buys Black a crucial tempo to organise a kingside defense. 30...Kf8 31.Qf3?! This lets the remaining attacking chances slip. Black can activate his queen and force a trade. White should still play 31.Qd4 despite Black having been able to block the d-pawn with the bishop. Ke7 32.Qe4+ Kf8! 32...Kd7 33.Qg4+ f5 34.Qd4+- 33.Bd4 Qb5! The queen comes back to d7 and Black holds. 31.Bf4 Bxf4 32.gxf4 Ke7= The blockade on the d-pawn is very firm and so Black probably has marginally better practical chances in this ending. 31...Qe1+ 32.Kg2 f5 33.g4 Qb1= Black has fully equalized here. Since his kingside pawns are all on light squares there is very little to fear from any same-colored bishop endgame. 34.Bd4 Kf7 35.Qe3 Qe4+ 36.Qxe4 fxe4 White never threatened to do anything in the bishop ending that follows. Black is always on time creating a passed b-pawn and if White tries to take it, he will either lose the h6-pawn or (much worse) the d5-pawn. 37.f3 exf3+ 38.Kxf3 Ke7 39.Ke4 Kd7 40.a4 Bc7 41.Be3 a6 42.Bd2 b5 43.axb5 axb5 44.Kd4 Bb6+ 45.Kd3 Bc5 46.Bc3 Ba3 47.Bg7 Bc5 48.Bc3 Bf8 49.Bg7 Be7 50.Kd4 Bd6 51.Bf6 Kc7 52.Bg5 Kb6 53.Bd8+ Ka6 54.Kd3 Bf8 55.Kd4 Bd6= ½–½

Ding Liren ½:½ Giri

World number three Ding Liren signed his first draw of the event in round four. Giri once again showed great preparation, using a 'confrontational' approach (Fernandez) with the black pieces from the get go. The Chinese, however, seems to have recovered his usual form, and assessed it was better to go for the safer alternative on move 18:

 
Ding Liren vs. Giri
Position after 17...Bd7

Ding thought Giri's h7-h5-h4 push was very strong, so instead of 18.♘d4 in the diagrammed position opted for 18.f4 in order to prevent an eventual ...h3. Giri later stated that his h-pawn push did not end up being an "AlphaZero manoeuvre" as was his intention.

Talking about relaxing activities during rest days, Ding said he usually reads a book and follows the news online. Giri usually follows the news as well, except he cannot escape hearing about the Coronavirus nonstop now, which prompted him to watch some local TV shows — except that they have a big drawback:

It turns out, without the fake laughter, jokes are really not funny any more.

1.d4 Nf6 2.c4 e6 3.g3 My own experience with the present structure has been quite limited, but I did make the following quite comfortable draw. 3.Nf3 Bb4+ 4.Nbd2 0-0 5.a3 Bxd2+ 6.Qxd2 b6 7.e3 a5 8.b3 c5 9.Be2 Ba6 10.0-0 d5 11.dxc5 bxc5 12.Bb2 ½-½ Papin,V-Fernandez,D Auckland 2020 3...Bb4+ 4.Bd2 a5 5.Bg2 d5 6.Nf3 0-0 7.Qc2 c5 This move is confrontational and leaves it up to White what the center will look like in 6-8 moves time. 7...b6!? Black's best scoring option and for good reason: it makes use of the move ...a5 in a sense which ...c5 does not really. 8.cxd5 8.0-0 Bb7 9.Bg5 Be7 10.Nc3 Na6 11.Rac1 Nb4 12.Qb1 dxc4 13.Rfd1 Qb8 14.a3 Nbd5 15.Nxd5 exd5 Tica,S-Kurajica,B Mali Losinj 2017 8...exd5 9.0-0 Re8 10.Bg5 Nbd7 11.a3 Bd6 12.Nc3 Ba6!? 13.Nxd5 Rxe2 14.Qf5 h6 15.Bh4 Bb7 16.Ne1 Bxd5 17.Bxd5 Rb8 18.Nd3 g5∞ Avrukh,B-Brown,M Chicago 2017 8.cxd5 This is the correct exchange and brings about a position which Black can almost never win. 8.dxc5 d4! 9.Bxb4 axb4 10.0-0 Nc6 11.Nbd2 e5 Black has such good dark squares here that White risks getting clobbered. Buhmann,R-Fressinet,L Germany 2014 8...cxd4 8...exd5 9.dxc5 Bg4 leads to the same structure as the game, but White can establish a fair grip on d4 while Black is busy using his b8-knight for other purposes (taking on c5.) 9.Nxd4 Qb6 9...Nxd5 10.0-0 Qb6 11.e3 Bd7 12.Nc3 Nf6 13.a3 Bc5 14.Nf3 Rc8 15.Na4 Bxa4 16.Qxa4 Nc6 17.Rfc1 h6= Black later won in Esipenko,A-Short, N Moscow 2018 due to a tactic, but in spite of the 'objective equality' here most people would rather take White. 10.e3 exd5 11.0-0 Nc6 12.Nxc6 bxc6 Black could also have played 12...Qxc6 13.Qxc6 bxc6 14.Rc1 Bd7 but in the absence of queens, the queenside needs to be a bit more clarified before Black is well-advised to go for this kind of thing. 13.Rc1 Rb8 14.Bxb4 Qxb4 15.b3 h5!? This isn't 'playing for a win', it's just a generally useful move almost regardless of circumstances. For instance, in a hypothetical 4v3 rook ending on the kingside, setting up with ...h5 and ...g6 is Black's surest way to draw. 16.Nc3 16.Qxc6?! Bf5! White doesn't have a good answer to ... Rfc8, causing various issues on the c-file. 17.Qa4 17.Qc3 Rfc8! 18.Qe1 Rxc1 19.Qxc1 Rc8 20.Qd1 Rc2 17...Rfc8 18.Rd1 Qxa4 19.bxa4 Rb2 The amount of pain White is going through is worth far more than the crippled, doubled extra a-pawn. 16...h4 17.Ne2 Bd7 18.Nf4 hxg3 19.hxg3 Rfc8 20.Bf3 a4 If Black were to just sit and wait for the f4-knight to get to c5, it would be quite a painful position to play. However, as it is the knight can never be supported by a pawn when it does get to c5. Thus, White's possession of an outside passed pawn is a mixed blessing: if he focuses too much on it Black plays ...Kd6 at some moment and begins pushing the c-pawn. 21.bxa4 Ra8 22.Nd3 Qxa4 23.Qxa4 Rxa4 24.Nc5 Ra5 25.a4 Rca8 26.Bd1 Be8 27.Kf1 Kf8 28.Rab1 Ne4! Black shows good understanding in mitigating his 'worst-case' risk: now the worst thing that can happen is needing to defend a 3v2 rook endgame. Black can also sit tight: 28...R8a7 29.g4 g5 30.Rc3 Ke7= 29.Nxe4 dxe4 30.Rb7 But it turns out White has no way to force the '3v2'. Maybe the best attempt would have been 30.Rb4 f5 31.g4 c5 32.Rb7= trying to exploit the slight looseness of Black's structure. 30...c5 31.Bb3 R5a7! Black has to calculate well when playing this (or else be sure that even if he loses the e4-pawn in a single-rook endgame, it can be held.) 32.Rxa7 Rxa7 33.Ke1 It turns out that White's rook doesn't have quite enough squares, and in a line like 33.Rxc5 Bxa4 34.Bxa4 Rxa4 35.Kg2 Ke7 36.g4 Kf6 37.Rf5+ Ke6 38.Kg3 Rc4 39.Kf4 f6= he isn't winning the e4-pawn and thus has no claim to a plus that can be used to torture Giri. 33...Ke7 34.Ra1 34.Kd2 Bxa4 35.Ra1? Rd7+! is the point. 34...c4! Now we'll reach a situation where neither side can make progress at all. 35.Bc2 Kd6 36.Kd2 Kc5 37.Kc3 Ra6 38.g4 g5 39.a5 Bc6 40.Ra2 Ra7 41.Ra1 Ra6 42.Ra2 ½–½

Wang Hao ½:½ Alekseenko

After having been caught under-prepared more than once before the rest day, Alekseenko managed to be the one surprising his opponent in round four. Given the circumstances, Wang Hao decided to play solidly, but anyway got to be the one pushing for more after his rival made a strange decision:

 
Wang Hao vs. Alekseenko
Position after 13.Rfc1

Alekseenko spent over 20 minutes on 13...a6, which he later described as 'an incredibly bad move'. 13...♞e4 or 13...♛xa4 were perhaps better alternatives to equalize. Anyway, White did not get more than a slight edge from this point on. The draw was agreed on move 41.

1.Nf3 For reasons that will become clear the present encounter reminded me of another attempt by a Chinese player to grind out a win from a symmetrical position in an elite event. 1.d4 Nf6 2.c4 g6 3.g3 c6 4.Bg2 d5 5.cxd5 cxd5 6.Nf3 Bg7 7.Ne5 0-0 8.Nc3 Bf5 9.0-0 Ne4 10.Bf4 Nxc3 11.bxc3 Nc6 12.Nxc6 bxc6 13.Qa4 e6 14.Qxc6 Rc8 15.Qa4 Rxc3 16.Rfc1 Rxc1+ 17.Rxc1 Qb6 18.e3 Qb2 19.Qd1 h5?! 20.a4 Bg4 21.Qe1 Be2 22.Bf1 Bxf1 23.Kxf1 Ding, L-Carlsen,M Shamkir Chess 2019 1...d5 2.g3 g6 3.Bg2 Bg7 4.d4 Nf6 5.0-0 0-0 6.c4 c6 7.Nbd2 a5 8.b3 Bf5 9.Bb2 a4 Introducing some imbalance; Black doesn't have that many constructive plans that don't involve playing this move at some stage. 10.bxa4 Qa5 11.Qb3 Nbd7 12.cxd5 cxd5 13.Rfc1 Ra6!? Trying to bait White into playing an interesting game after all. 13...Ne4 This seems to be a more reliable way to equalize. 14.e3 White tries to play the slow game, but Black is completely fine as long as he stays alert to which exchanges are helpful and when. It was possible to take the pawn since neither attempt by Black to win the b2-bishop is crowned with success. 14.Qxb7!? Rb6 14...Rb8 15.Rc8+ Rxc8 16.Qxc8+ 15.Qc7 Qxa4 16.Nb3 Qa6 17.Bf1∞ It seems to me that Black has compensation, and there is obviously some danger that White will misplace the a2-pawn and be left with less space, but this is still the way to play for a win. 14...Qxa4 15.Bf1 Qxb3 15...Ra7 16.Rc7 16.axb3 Rxa1 17.Rxa1 Nb6 18.Ra7! White has to try and get in now, before Black plays ...Ra8. Rb8 19.Ne5 Nfd7 The engine wants to reroute with 19...Nc8 20.Ra5 Nd6 but it isn't clear that the exchange on e4 is all that beneficial after, for instance, 21.Ba3!? 19...g5!? 20.Bb5 f6 It is also possible to be clever. 20...Nxe5 21.dxe5 Nc8 22.Ra1 22.Ra2 Nb6 23.Bd4 Ra8= 22...Nd6 23.Bf1 Ne4 24.Nf3 e6= 21.Nxd7 Bxd7 22.Ra5 Bf5! Alekseenko stays very solid in this phase of the game and simply doesn't give Wang anything to work with. 23.Ba3 Bf8 24.Bc5 After something else like 24.f3 Black simply plays Ra8= and the worse positioning of his pieces is a very transient factor indeed. 24...Nd7 25.Ra7 White has to try this but he has little advantage in any case. Nxc5 26.dxc5 e5 27.b4 b6 28.c6 28.Bc6 looks promising, but there's no particular danger from either the b-pawn or the cornered king. bxc5 29.Bxd5+ Kh8 30.b5 Rxb5 31.Rf7 Bg7= 28...Bxb4 29.e4 dxe4 30.Nxe4 30.g4 Bxg4 31.Nxe4 Rf8∞ This would have been tricky for both sides to play; the c6-pawn looks like it's worth a piece, but there's no concrete way to gain a piece for it. 30...Bxe4 31.c7 Rf8 32.Bc4+ Kh8 33.Be6 Bf5 34.c8Q Rxc8 35.Bxc8 Bxc8 36.Ra8 Kg7 37.Rxc8 Bc5 Neither side has any realistic winning chances in this endgame. 38.Rc7+ Kh6 39.h4 f5 40.Kg2 e4 41.Kf1 ½–½
