Shenzhen: Giri does it!

by Macauley Peterson
4/27/2019 – In Shenzehn, China, Pentala Harikrishna defeated Yu Yangyi in the penultimate round to retake a half point lead over Anish Giri. But he had Black in the final round while Giri was White. Could 'Hari' score his first super-tournament victory? It looked like he was headed for a tournament-clinching draw, but a slip-up gave Ding Liren a chance to turn the tables and Giri a golden opportunity to grab tournament victory. | Photo: cca.imsa.cn

Harikrishna takes half point edge to final

That Harikrishna is leading the Shenzhen Masters heading into the final round is not itself surprising, but what is remarkable is that he's doing so despite having lost two games!

After a seventh round of three draws, Richard Rapport dealt Harikrishna his second loss of the tournament in round eight and allowed Anish Giri to pull equal with two rounds to play. Since Giri beat 'Hari' in round two, the Dutchman has the tiebreak advantage should the finish on equal points — the first tiebreak is 'direct encounter'.

The realization of White's small material advantage (two flank pawns) was difficult.

Position after 57.Kg5

The black king controls the h-pawn, while his minor pieces prevent the a-pawn's advance. If necessary, Black can also sacrifice a piece and aim for a draw of one piece against two (without pawns).

The White knight obstructs his own pawn on the a-file and is also dominated by the black bishop. Important now was 57...♚g8 58.♔g6 ♞e5+ 59.♔f6 ♞c6 60.♗b6 ♝e5+ 61.♔xe6 ♝c3 and so on, or 57...e5 58.♔f5 e4 59.♔xe4 ♝e7 etc., would also have been sufficient.

But Black instead let the White knight out of prison: 57...a3?. There followed 58.b8 c1+ 59.h4 e8 60.c7 e3 61.a6 a3 62.g4 b5 63.f4 c5 64.c6 d7 65.e5+ e8 66.h6 f8 67.h7 g7 68.h5 1-0

Giri drew with Ding Liren to tie for the lead, with momentum on his side.

Harikrishna showed his resilience in the penultimate round, however, and he went after his opponent's Petroff Defence in yet another queenless middlegame. Eventually Harikrishna won a pawn and in the endgame the players reached this position:

Position after 51.Bd3

Black played 51...c5 and after 52.e4+ he faced an unpleasant choice: He decided to swap the minor pieces with 51...♞xe4+, but the rook ending is straightforwardly lost: 53.xe4 a7 54.a4 c5 55.g3 b5 56.a2 h5 57. f4 1-0

52...♚d4 was no better, as there would follow 53.♗b7 and the a-pawn runs next.

1.e4 e5 2.Nf3 Nf6 Somehow I find it curious that an attacking player and excellent calculator like Yu Yangyi plays the Petroff. 3.Nxe5 d6 4.Nd3!? Harikrishna avoids the main line and uses a positional weapon that he has prepared. Nxe4 5.Qe2 Qe7 6.Nc3 6.Nf4 Nc6 7.Nd5 Nd4 was played at the Carlsen Caruana World Championship Match. 6...Nf6 6...Nxc3 is definitely a playable alternative. 7.dxc3 Qxe2+ 8.Bxe2 Nc6 9.Be3 gives White a developmental edge. 7.Nf4 c6 8.d4 Qxe2+ 9.Bxe2 d5 10.0-0 Bd6 10...Bf5 is a possible move, but after 11.Re1 The king on e8 already starts to feel uncomfortable. Be7 12.Bd3 Bxd3 13.Nxd3 White's position is to be preferred. 11.Bd3 0-0 12.Nfe2 The knight retreats to e2 to make the f4 square available for the bishop. Ne8 The first time you see the move, it just seems wrong. Black is undeveloping the knight without any provocation. But when you delve deeper you understand the point of this move, not just in chess terms but also in psychological. In chess terms, Black wants to prepare against Bf4 by exchanging his bishops and getting the knight to d6. In psychological terms, Hari and Yu Yangyi had already played this position before where Yu Yangyi had played Nbd7 and would not have been comfortable with the resulting positions. 12...Nbd7 13.Bf4 Bxf4 14.Nxf4 Re8 15.f3 Nf8 16.h4 h5 17.Rfe1 Bd7 18.Kf2 g6 19.b4 Rxe1 20.Rxe1 Re8 21.Rb1 Ne6 22.Nxe6 Bxe6 23.b5 Rc8 24.bxc6 Rxc6 25.Rb3 Kf8 26.Ne2 Rc7 27.Nf4 Bd7 28.Ke3 Ke7 29.Kd2 Kd6 30.Rb1 b6 31.Re1 Rc8 32.Ra1 Ba4 33.Nh3 Nh7 34.Nf4 Nf6 35.Ne2 Bd7 36.a4 Ne8 37.Nc3 a5 38.Nd1 Nc7 39.Ne3 Ne6 40.c3 f5 41.Bc2 f4 42.Nd1 g5 43.hxg5 Nxg5 44.Rb1 Rb8 45.Nf2 h4 46.Nd3 h3 47.gxh3 Nxf3+ 48.Ke2 Ng5 49.Nxf4 Nxh3 50.Nxh3 1/2-1/2 (50) Harikrishna,P (2727)-Yu,Y (2760) China 2018 13.Re1 Nd7 14.Bf4 Hari keeps it simple, he exchanges the bishops and doesn't try too hard to make the knight on e8 look funny. Nb6?! This move definitely seems wrong. After a move like b3 the knight on b6 won't be doing anything active. 14...Bxf4 15.Nxf4 Ndf6 The other knight will come to d6 and it looks fine for Black. 15.f3! A nice move taking the e4 square away, but more importantly preparing to activate the king to f2. a5 16.a4 Bd7 17.b3 h6?! This move in itself doesn't make much sense. Black wants to play g5 at some point to force White's hand. However, this same pawn will become a weakness and help White to open more lines with h4. 18.Nd1 g5 19.Bxd6 Nxd6 20.Nb2 Rac8 21.Kf2! The king clears the last rank, gets closer to the game and prepares h4 followed by gxh4 and Rh1. Na8 As mentioned earlier, the knight on b6 was not at all useful and tries to look for better squares. 21...c5?! 22.dxc5 Rxc5 23.Nd4± 22.h4! f6 22...gxh4 23.Rh1 h3 24.Rag1± 24.g4 f5 23.Rh1 Kg7 24.Ng3 The knight is ideally placed looking at all the weaknesses. Nc7 25.c4! Harikrishna is playing on both sides of the board. The idea is c5 pushing Black further behind. b6 26.Rac1 26.c5 bxc5 27.dxc5 Nb7 makes the c5 pawn weak. 26...dxc4? A very bad positional error by Yu Yangyi. 26...f5 This was definitely better. It is possible to feel that the g5 pawn can become weak. But this was a situation for desperate measures and Black has to go for it. 27.hxg5 hxg5 28.Rh5 Rh8! 28...Kg6 29.Rch1± 29.Rxg5+ Kf6 30.f4 Ne6 Black pieces suddenly spring to action. 31.Nxf5 Nxc4! 31...Nxg5 32.fxg5+ Ke6 33.Re1+ Ne4+ 34.Bxe4 dxe4 35.g4± 32.bxc4 Nxf4 33.Rg4 Nxd3+ 34.Nxd3 Bxf5∞ 27.Nxc4 The b6 pawn is falling now, so the knight has to be taken. Nxc4 28.bxc4 The net result of taking on c4 is that the b6 pawn is extremely weak and White has a central majority which is quite easy to get rolling. Rcd8 28...Na6 29.Bf5! Rcd8 30.Bxd7 Rxd7 31.Nf5+ Kg6 32.g4+- The knight on f5 is dominant. 29.Rb1 Be6 30.hxg5 30.Bf5 was a strong move. Bxc4 30...Rxd4 31.Bxe6 Nxe6 32.Nf5++- 31.Rxb6 Bd5 32.Be4+- 30...fxg5 31.Rxb6 Rxd4 32.Ke3 Rfd8 33.Be2 There is no good way to defend the c6 pawn. R4d7 33...R4d6 34.Ne4+- 34.Rxc6 Re7 35.Kf2 Rdd7 36.Rb1 White is a pawn up and is much more active. For a player like Harikrishna, this is quite easy to convert. Ne8 37.Rbb6 Kf7 38.Ne4 Rc7 39.Rxc7 Rxc7 40.c5 Ke7 41.Ra6 Ng7 42.Rxa5 Nf5 43.Ra8 Bd5 44.Rh8 Ke6 44...Bxe4 45.fxe4+- 45.a5 45.g4 Bxe4 46.fxe4 Nd4 47.Rxh6+ Ke5 Black gets unnecessary counterplay. 45...Ke5 46.a6 Nd4 46...Bxe4 47.fxe4 Kxe4 48.Bf3+ Ke5 49.Re8+ Kf6 50.Bb7+- 47.Re8+ Ne6 48.Bb5 Kd4 49.Nf6 Kxc5 50.Nxd5 Kxd5 51.Bd3 Nc5 52.Be4+ Nxe4+ 52...Kc4 53.Bb7 Nxb7 54.a7+- 53.Rxe4 Ra7 54.Ra4 The rook is tethered to the a-pawn. The White king will go to the kingside and gobble things up. Kc5 55.Kg3 Kb5 56.Ra2 h5 57.f4 A fantastic effort by Harikrishna, who is choosing the right kind of positions that are the most uncomfortable for his opponents, and making them go wrong. 1–0

Rapport against Giri was an Open Catalan in which Rapport followed Wojtaszek vs Giri from the 2018 Shamkir tournament through a whopping 23 moves into a dead-equal endgame. The players shook hands on move 32 after using up very little time on the clock. Giri had a free evening to contemplate last round strategy:

UPDATE: Harikrishna stumbles and Giri takes advantage

In a dramatic turn of events in the final round Harikrishna lost, giving Giri the opening he needed to press with White and ultimately win his long minor piece endgame against Dmitry Jakovenko to leapfrog the Indian number two and win the Shenzhen Masters with a final score of 6½ / 10.

Ding Liren is Anish's new best friend. He manoeuvred patiently with White in an English Opening, but by move 24 when the queens came off, the symmetrical pawn structure and equal material made a draw look likely.

Reminiscent of a Knight's Tour!

Ding has just vacated the knight outpost on c5 and Harikrishna now takes time to ensure the knight does not return with 35...b6, however in the long run that opens up the new and more lucrative c6-square for the knight. Black's own advanced knight on f3 meanwhile lacks meaningful targets. 35...g5 would have been a logical follow-up, when White's edge is minimal.

Harikrishna avoided exchanging knights, but soon Ding's developed a dominating position:

46.h8 with the other rook coming to c8, Ding later corralled the d5-pawn with a winning advantage. But he embarked on a spurious mating net, driving Harikrishna's king to g1 and giving him a golden opportunity to save the game — and his tournament — with a tactic:

 
Position after 59.Rh5

Can you spot the idea Harikrishna missed?

In the game Harikrishna played 59...d6 and gave Ding a second chance to win. The game continued 60.d5 g6 61.h7 d6 and now Ding managed to break through:

62.a5! The passed pawn that results will decide the game in White's favour.

Giri needed 97 moves [the live broadcast incorrectly showed only 64 moves at first after a technical snafu -Ed.] and the full seven hours to prosecute his endgame advantage against Jakovenko, but he succeeded and, with that, won the tournament:
