Hikaru Nakamura played a quite instructive game against Daniil Dubov and scored a key win in his match.
This is a rapid game played online in the chess24.com chess24 Magnus Finals tournament, in August 2020.
The Sveshnikov Variation has become very popular in master level chess
Hikaru is White, and Dubov is Black.
1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6 8. Na3 b5 9. Nd5 Be7
They reached the following position after Black played 19..Qe8 to prevent b4-b5
White has a passed pawn on the b column and played 20 Be2. Dubov started counterplay with f7-f5 which is standard in this sicilian opening.
Eventually, they reached the following with white to play
Hikaru played 31 Ne3! the best move of the game. It deprives black from the bishop pair and targets the d6 pawn. Also the knight will jump to c4-a5-c6 which will be hard to defend against, as the dark square bishop is weaker than White's knight
and here is the final key moment, White to Play
Here Hikaru played 38 Rdc1! with the idea Nc6. Black tried 38..Bf4. Hikaru continued 39 Qc8+ Rd8 40 Qxd8 queen sacrifice with advantage but either 39 Qc7 or 39Nc6 was winning on the spot .
