He will meet eight-seeded American Hikaru Nakamura in a two-set best-of-four matchup.
Nakamura, 33, dug deep to beat Azeri Shakriyar Mamedyarov, 5-4, in the deciding Armageddon tie-break.

2021 New in Chess Classic Semifinal Knockout Game 4
W) S. Mamedyarov (AZE)
B) H. Nakamura (USA)
Nimzo-Indian Defense
1. d4 Nf6
2. c4 e6
3. Nc3 Bb4
The Nimzo-Indian Defense, a flexible hypermodern opening, introduced into practice a century ago by Aron Nimzowitsch (1886-1935), a well-known Danish world contender and writer.
4. Nf3 ....
The Kasparov Variation, popularized by former Russian world champion Garry Kasparov during the 1985 Kasparov-Karpov World Championship match.
4.... O-O
5. Bg5 c5!
It is well known that this system of development leads to equality. The alternative 5.....d6 6. e3 Nbd7 7. Qc2 b6 8. Bd3 Bxc3ch 9. bxc3! h6 10. Bh4 Bb7 11. Nd2!, slightly favors White.
6. Rc1 ....
After 6. e3 cxd4 7. exd4 h6 8. Bh4 d5 (8....Qa5 9. Bd3!? Bxc3ch 10. bxc3 Qxc3ch 11. Kf1 is unclear) 9. Rc1 Nc6 10. c5 g5! 11. Bg3 Ne4, the game is probably equal.
6.... h6
7. Bh4 cxd4
8. Nxd4 d5
9. cxd5 g5
10. Bg3 Qxd5
11. e3!? ....
An interesting Pawn sacrifice, which aims to complicate matters.
11.... Qxa2
12. Bd3!? ....
White sacs another Pawn for rapid development and possible Kingside assault. Other tries, however, leads to a good game for Black, e.g., 12. Qc2 Nd5 13. h4 g4 14. Bd3 Bxc3ch 15. bxc3 Qxc2 16. Rxc2 Nd7, and Black has nothing to fear.
12.... Qxb2
13. O-O Bxc3
14. Rc2 Qb4
15. Nb5 e5
16. Rxc3 ....
In Mamedyarov-Nakamura Game 5, play continued 16. Nxc3 Nc6 17. Qc1 Rd8 18. Rb2 Qc5 19. Bb1 Be6 20. Rb5 Qc4? 21. Ba2 Qd3 22. Bxe6 fxe6 23. Rxb7, and White wrests the initiative. (1-0 =61)
16.... Nc6
17. f4 Bg4
18. Qc2 ....
The players followed Game 2 of their semifinal match which went 18....Qe7 19. fxe5 Nh5 20. Be1 a6 21. Nd4 Nxe5 22. Rc7 Qd6 23.. Bh7ch Kh8 24. Bf5, and White obtains a decisive advantage (1-0 =33)
18.... exf4!
And here’s Nakamura’s improvement, (which the engine recommended), from the above-mentioned game.
19. exf4 Nd5
20. fxg5? ....
The decisive error, as the c3 Rook is vital in White’s planned K-side assault.
20.... Nxc3
21. Nxc3 Rad8
22. Kh1 Qd4
Now Black’s pieces are actively posted and White’s attack will soon fizzle out. The rest, which needs no comment, is a routine technique for the American Blitz champion.
23. Bh7ch, Kh8; 24. h3, Bh5; 25. Rf6, Qe3; 26. Bf2, Qxg5; 27. Ne4, Qg7; 28. Bf5, Nd4; 29. Bxd4, Rxd4; 30. Qf2, Rdd8; 31. Qh4, Bg6; 32. Nf2, Rd5; 33. Ng4 , Rxf5.

Solution to last week’s puzzle:
White to move and win.
White=Kd4, Rd8, Nd5, Pa6, Pc7, Pg2
Black=Kg7, Rc6, Bg4, Pa7, Ph4
1. Rg8ch! 1-0
