This is too sophisticated. The direct 60.d6! wins, e.g. Qe4+ 61.Kf6 f4 62.gxf4 Qxf4+ 63.Ke7 Qe5+ 64.Kd8 Qh8+ 65.Kc7 Qc3+ 66.Qc6 Qxa5+ 67.Kc8 Now the d-pawn wins easily and Black's g-pawn is not really relevant, e.g. g4 68.d7 Qf5 69.Kc7 Qa5+ 70.Kb7 g3 71.Qf3+ Kh4 72.Qf6+ Kh3 73.Qh8+ Kg2 74.d8Q+- 60...Qxg3+ 61.Kf6 Qc3+ 62.Qe5 Of course not 62.Kxf5??

Vers surprisingly this loses. Black's king can enter the main drawing zone with 73...Kg2= 74.Ke2+? 74.Ke4+ mates in 49 moves as after Kg2 75.Qe2+ Black's king is driven away from the drawing zone: Kg3 76.Qe3+ Kg4 76...Kg2?! 77.Qg5+ Kh1 78.Qh4+ Kg2 79.Qg4+ Kh1 80.Qf3++- 77.a7+- 74...Kg2 75.Qe4+ Kh2 76.Qh4+ Kg2 77.Qg5+ Kh2 78.Qe5+ Kg2 79.Qe4+ Kh2 80.Ke3 Qb3+ 81.Kf2 Qb6+ 82.Kf3 Qb3+!

Carlsen,M2847Nepomniachtchi,I2789½–½2021D24Magnus Carlsen Invitational-KO 20212.1

Since the second game didn’t yield more than half a point either, the Norwegian lost patience in the third encounter. Here Ian Nepomniachtchi had temporarily taken the initiative with a piece sacrifice. Objectively, the game was balanced after the piece was won back, but then Carlsen tried to force his way to a full point with an exchange sacrifice. But it did not work.

The fourth game also ended in a draw, so Nepomniachtchi goes into the second day of the semis only needing a draw to reach the final.

Giri bounces back

In the semifinal between Anish Giri and Wesley So, it initially looked as if the American grandmaster might continue his winning streak from the earlier tournaments in the series, as he won the first game. However, Anish Giri hit back in the third game after a draw in game 2.

 
Giri-So, 3. Partie

31.Re4 Qd5? [31...f5 32.Re1 Qd5 was playable. But White is more active.]

32.exf6+ Kxf6 33.Re5 Qd7 34.Rg5 [An immediate 34.Nh4 was even stronger.]

34...Qd6 35.Rf2 Kg7 36.Nh4 Re6

 

37.Nf5+ [Winning the exchange.]

37...Rxf5 38.Rfxf5 Qxd4 39.Rg4 Qd6 40.Rf2 Re3 41.Re2 Rd3 42.Qf2 c5 43.Rg5 c4 44.Rge5 Nxg3 45.Re7+ Kh6 46.Qf8+ Kg5 47.Rg2 

 

42... Re3?

[47...Kh4 was a slightly better attempt: 48.Rh7+ (48.Qh8+? Nh5+ 49.Qe5 (49.Kh1? Rxh3+ 50.Kg1 Qd1+ 51.Kf2 Rf3#) 49...Rxh3+ 50.Kg1 Qd1+ 51.Qe1+ with equal chances.) 48...Nh5+ 49.Qxd6 Rxh3+ 50.Kg1 cxd6 51.Rxg6 The black pawns are weak and difficult to hold.]

48.Rf7 Qd1 49.Rf1 Qd3 50.Rf4 [The mate threat of h4 and Qh8 decides.] 1–0

The Dutchman also won game 4 for a 2½:1½ overall victory.

 
So-Giri, 4. Partie

27.Bg4 Rf8 28.Bf5 Rf6 29.Qe2 Qf7 30.Qg4? [With 30.Rg5 h6 31.Rh5 Rf8 32.g4 the white position is still holdable.]  30...Rf8 [Black is too strong along the f-file.]

31.Rf2 Kh8 [Of course not 31...Rxf5 32.Rxf5 Qxf5 33.Qxg7#]

32.Be6 Qe7 33.Bf5 Bh6 34.Rh3 Qe5 35.Rf1 Rxf5 36.Rxf5 Rxf5 [36...Rxf5 37.Rxh6 Qa1+]

0–1
