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.
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:
On top level the Berlin Defense is a popular defensive weapon but it also offers Black good chances to win if White does not proceed precisely. On this DVD Victor Bologan shows what Black can and should do if White tries to avoid the main lines of the Berlin Defense.
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.

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.g3Bxg515.Bxg5Rg616.Bf4Nh4=Fedorchuk,S-Malakhov,V Brest 201814...Bb4Before

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:
The Grunfeld Defence is a very dynamic opening with an excellent reputation and the list of players ready to defend it reads like a who's who in chess. It is rather remarkable, that one variation still retains the position of 'main line' and that after hundreds of games played with it some questions still remain open. GM Lubomir Ftacnik explains.
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.

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:
1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+ 4.Bd2 Qe7 5.g3 Bxd2!? 6.Qxd2 Nc6! 7.Nc3 d5! is a modern line where Black tries to play actively in the center. Shah shows the possible variations which occur in this position.
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.

This is the correct exchange and brings about a position which Black can
almost never win.8.dxc5d4!9.Bxb4axb410.0-0Nc611.Nbd2e5
Black has such good dark squares here that White risks getting clobbered.
Buhmann,R-Fressinet,L Germany 20148...cxd48...exd59.dxc5Bg4leads
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.Nxd4Qb69...Nxd510.0-0Qb611.e3Bd712.Nc3Nf613.a3Bc514.Nf3Rc815.Na4Bxa416.Qxa4Nc617.Rfc1h6=Black later won in Esipenko,A-Short,

most people would rather take White.10.e3exd511.0-0Nc612.Nxc6bxc6
Black could also have played12...Qxc613.Qxc6bxc614.Rc1Bd7but 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.Rc1Rb814.Bxb4Qxb415.b3h5!?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.Nc316.Qxc6?!Bf5!White doesn't have a good answer to ...
Rfc8, causing various issues on the c-file.17.Qa417.Qc3Rfc8!18.Qe1Rxc119.Qxc1Rc820.Qd1Rc217...Rfc818.Rd1Qxa419.bxa4Rb2
The amount of pain White is going through is worth far more than the crippled,
doubled extra a-pawn.16...h417.Ne2Bd718.Nf4hxg319.hxg3Rfc820.Bf3a4If 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.bxa4Ra822.Nd3Qxa423.Qxa4Rxa424.Nc5Ra525.a4Rca826.Bd1Be827.Kf1Kf828.Rab1Ne4!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...R8a729.g4g530.Rc3Ke7=29.Nxe4dxe430.Rb7But it turns out White has no way to force the '3v2'.
Maybe the best attempt would have been30.Rb4f531.g4c532.Rb7=
trying to exploit the slight looseness of Black's structure.30...c531.Bb3R5a7!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.Rxa7Rxa733.Ke1It turns out that White's rook doesn't have quite enough
squares, and in a line like33.Rxc5Bxa434.Bxa4Rxa435.Kg2Ke736.g4Kf637.Rf5+Ke638.Kg3Rc439.Kf4f6=he isn't winning the e4-pawn and thus
has no claim to a plus that can be used to torture Giri.33...Ke734.Ra134.Kd2Bxa435.Ra1?Rd7+!is the point.34...c4!Now we'll reach
a situation where neither side can make progress at all.35.Bc2Kd636.Kd2Kc537.Kc3Ra638.g4g539.a5Bc640.Ra2Ra741.Ra1Ra642.Ra2½–½

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.Nf3For 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.d4Nf62.c4g63.g3c64.Bg2d55.cxd5cxd56.Nf3Bg77.Ne50-08.Nc3Bf59.0-0Ne410.Bf4Nxc311.bxc3Nc612.Nxc6bxc613.Qa4e614.Qxc6Rc815.Qa4Rxc316.Rfc1Rxc1+17.Rxc1Qb618.e3Qb219.Qd1h5?!20.a4Bg421.Qe1Be222.Bf1Bxf123.Kxf1Ding,

at some stage.10.bxa4Qa511.Qb3Nbd712.cxd5cxd513.Rfc1Ra6!?
Trying to bait White into playing an interesting game after all.13...Ne4
This seems to be a more reliable way to equalize.14.e3White 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!?Rb614...Rb815.Rc8+Rxc816.Qxc8+15.Qc7Qxa416.Nb3Qa617.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...Qxa415.Bf1Qxb315...Ra716.Rc716.axb3Rxa117.Rxa1Nb618.Ra7!White has
to try and get in now, before Black plays ...Ra8.Rb819.Ne5Nfd7The

the exchange on e4 is all that beneficial after, for instance,21.Ba3!?19...g5!?20.Bb5f6It is also possible to be clever.20...Nxe521.dxe5Nc822.Ra122.Ra2Nb623.Bd4Ra8=22...Nd623.Bf1Ne424.Nf3e6=21.Nxd7Bxd722.Ra5Bf5!Alekseenko stays very solid in this phase
of the game and simply doesn't give Wang anything to work with.23.Ba3Bf824.Bc5After something else like24.f3Black simply playsRa8=
and the worse positioning of his pieces is a very transient factor indeed.24...Nd725.Ra7White has to try this but he has little advantage in any
case.Nxc526.dxc5e527.b4b628.c628.Bc6looks promising, but
there's no particular danger from either the b-pawn or the cornered king.bxc529.Bxd5+Kh830.b5Rxb531.Rf7Bg7=28...Bxb429.e4dxe430.Nxe430.g4Bxg431.Nxe4Rf8∞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...Bxe431.c7Rf832.Bc4+Kh833.Be6Bf534.c8QRxc835.Bxc8Bxc836.Ra8Kg737.Rxc8Bc5Neither side has any realistic winning
