Alireza Firouzja shows us the black side of a tricky Taimanov line.
1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nc3 Qc7 6. Ndb5
6.. Qb8 7. Be3 a6 8. Bb6 !?
Black has to take it and defend.
8..axb5 9. Nxb5
-First idea 9...Ra5 10.Nc7+ Ke7 11.Qf3! Re5 12.Qa3+ d6 13.0–0–0 f6 14.Qa4.The queen in this variation goes to f3 and then a3 with pressure on a3-f8 diagonal.
-The second idea is 9..Bb4+ followed by Ba5 to indirectly cover c7.
lets look at this line.9.. Bb4+ 10. c3 Ba5 11. Nc7+
11..Qxc7 12. Bxc7 Bxc7 13. g3 Nf6 14. Bg2 O-O
How to continue here ? Lets see Alireza Firouzja in Katara Event Aug 26 2020 win easily.
got the privilege to play in a Hikaru arena and got faced with GM Hikaru Nakamura himself in a blitz 3 minutes for each player.
needless to say, I lost but this is quite an instructive loss I think.

1. e4 d5 2. exd5 Qxd5 3. Nf3 Nf6 4. d4 c5
here Hikaru surprised me with 4..c5. The best answer is 5 Nc3 to develop a piece followed by Bf4. I played 5c4 and 6 d5 which is ok.
5. c4 Qd8 6. d5 g6 7. Nc3 Bg4 8. Be2 Bg7 9. h3 Bxf3 10. Bxf3 Nbd7 11. O-O O-O 12. Bf4
we reached the following position with Black to play.
Here Nakamura uncorked 12..Ne8!An excellent idea ! Black plans to relocate knight from e8 to d6. from there, Black will play Ra8-b8 and a6-b5 creating pressure on my queenside pawn. This move opens the diagonal h8-a1 for the bishop on g7.
I suggest to replay the moves in the app below.
We reached the following position after 17..Nf6, White to play
it was time to start white's counterplay on the kingside with f4-f5, starting with 18 f4! instead I played 18 Rfe1 and Black started to put further pressure
18..b5 19. cxb5 axb5 20. Rad1 b4 21. Na4 Black to play
Hikaru played 21..c4 and I cannot capture the pawn as I need to protect the knight on a4. I had to play 22Qf4! attacking b4 if he pushes the c pawn further. Instead I played 22 Re3 and 22.c3 give Black a large advantage which Black converted without trouble.
Here's the replay from 21 Na4
Final position after 31..c2!
This occurs after 1e4 c5 2Nc3 Nc6 3Bb5 Nd4 4Bc4
<
4..g6 5 Nge2 Bg7 6 Nd4 cd4 7Qf3!
Here Black can play 7..Nh6 or 7..Nf6 but the most natural human move is 7..e6?! which leads to the trap White has set up !
7..e6?! 8 Nb5 d6 9Qa3!
Black has to defend d6 and play 9..Ke7
White has exploited the weaknesses of dark squares after 5..Bg7 by targetting c7 and d6 playing Nb5 as Black didn't have time to play a7-a6.
after 9..Ke7 10c3! white is better. You Hifan won against Pia Cramling in 19 moves.
Note that Black can try 8..d5 instead of 8..d6 but White has 9Qg3! with Nc7+ winning the exchange.
Berlin Wall is the position after 1 e4 e5 2 Nf3 Nc6 3 Bb5 Nf6 in the www.chess24.com finals.
Hikaru chose anti-berlin 4 d3 on which Carlsen plays the most popular and active 4..Bc5
6. Nbd2 O-O (6..Bg4 was played by Carlsen before) 7. Qe2
White hasn't decided where his king will castle
7..Re8 8. Nc4 Nd7 9. Bd2 b5 10. Ne3 Nf8 11. h4 Ne6? (11..a5 was safer)
White to play , what did Magnus miss with Black ? I am sure he intended 12..Nd4 but white has 13Nf7! Ne2 14Nd8 with 2 pawns up
12. Nxe5 a5? 13. Qh5! g6 14. Qf3 f6 15. Nxc6! Qd7 16. Qxf6 Qxc6 17. Bc3
Position after 17 Bc3!
White threatens 18 Qh8+ and h7, and has already 3 pawns for the piece. White can continue the attack with h4-h5 as well as 0-0-0 followed by d3-d4
17...Rf8 18. Qh8+ Kf7 19. Qxh7+ Ke8 20. Qxg6+ Kd7 21. d4 b4 22. dxc5 1-0
very convincing win by Hikaru today in the berlin
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
Nakamura continued with 10Bf6They 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 .
