My game against Hikaru Nakamura : PGN and Animated replay

Replay available here

My blitz game against Hikaru Nakamura Aug 2020- Scandinavian

 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.

[White "thechesscorner64"][Black "Hikaru"][WhiteElo "2402"][BlackElo "3218"]

[Result "0-1"][ECO "B01"][Date "2020.08.22"]

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.

[#] 12. Bf4 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. 13. Qd2 ( 13. Rc1 Nd6 14. b3 a6 15. Re1 b5 16. Ne4 ) 13...  Nd6 14. b3 14...  Re8 15. Bh6?! exchanging the bishops but Black continues with the expansion on the queeside ( 15. Rac1 a6 16. Ne4! the knight on d6 needs to be challenged and this attacks c5 as well 16... Ne5 17. Qe2 b6 18. g4!? ) 15...  Bxh6 ( 15... Bh8 16. Rfe1 ) 16. Qxh6 16...  a6 17. Bg4 17...  Nf6

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

[#] 21. Na4 c4! 22. Re3? ( 22. Qf4! To attack b4 22... c3 ( 22... Ra5 23. Bf3 Qb8 24. Rd4 Qa7 ( 24... Nf5 25. Qxb8 Rxb8 26. Rxc4 ) 25. g4 ) 23. Qxb4 ) 22...  c3!

Final position after 31..c2!

Sicilian 2Nc3 Nc6 3Bb5!? trap

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.

a very important move to prepare f7-f5 and the knight will go back to f6 or d6. Black wants to play Ba6 pressuring c5. Magnus had played this against Giri and Anand in the last months so Hikaru was prepared.

  

  10. O-O Ba6 11. f4 f5! 

White to play

 

The game continued and Hikaru increased his advantage with Black. After his move 30..Nd2! we reached the following 

White to play

If white takes the knight 31 Nxd2 31..Qe3+ wins it back with attack against the king. Magnus pieces ( queen and rook) are too far to defend the lone white king. Magnus played 31 Rd8 but the following occured:31. Rd8 Nxf1 32. Qxf1 Qe3+ 33. Kh2 Re4

Colle-Zukertort ideas

Colle Zukertort is the system where white decides to fianchetto his dark square bishop b3,Bb2, plays e3,d4 as well as Bd3,Nbd2 and Nf3. Here is what white starts the game with

 

and in a real life game, here's the position for white where f2-f4 is also played.

Remember to play actively with White, setting the board on fire. Use the a1-h8 and b1-h7 diagonals with your bishops. Bring your knights to the kingside.

Like this :

Now lets see full games with this system with the white pieces.

Ding Liren wins Brilliant Game against Magnus Carlsen in King's Indian Defence: chess24 magnus tour finals Aug 2020

In this entry, I will analyze a game where Magnus plays the King's Indian Defense with Black and Ding outplays it with near perfect play. lots of tactics to calculate and Ding was up to the task.

  www.chess24.com for full coverage 

 
Great example where Ding Liren quickly built pressure againt Magnus who wasn't really up to speed with KID structures. Ding has mastered positions with 1d4 and g3,Bg2 fianchetto. His calculation ability is world class level even though he started poorly in candidates 2020 first half and will not challenge Magnus for World Championship ( it will be either Nepo,MVL or Caruana again).

Ding was impressive with the line starting with 24Bh6! and played perfectly until 31 Qf4 checkmate. Magnus could have defended better if he found Bd4+ in several instances but instead lost very quickly

1. d4 Nf6 2. c4 g6 3. g3 Bg7 Magnus going for Kings Indian 4. Bg2 O-O 5. Nc3 d6 6. Nf3 Nc6 7. O-O e5 8. d5 Ne7 9. e4 white will play on the queenside, black will move Nf6 to start f7-f5, but needs to play h7-h6 first to prevent Nf3-g5! 9...  b6 10. Rb1 a5 11. Re1 Nd7 12. a3 h6 13. Nh4! the best approach against f7-f5 plan from Black 13...  f5 14. exf5 gxf5 15. Qc2 Nf6 16. b4 Bd7 17. c5! Blacks plan of Nf6-d7,h6,f7-f5 and Nd7-f6 is too slow. White is making progress on the queenside and does not have any large weakness 17...  axb4 18. axb4 e4? this is clearly a mistake as white can attack e4 and f5 which will open up kingside. opening went wrong for Magnus. ( 18... Bc8 19. c6 ) ( 18... Qe8! the best move 19. c6 ( 19. cxd6 cxd6 20. Bb2 Qf7 ) 19... Bc8 20. Qb3 ) ( 18... bxc5 19. bxc5 Ra5 20. c6 Be8 ) 19. c6 Be8 20. f3!

Bxe4 Nc3 very sharp ( 23... Bd4+! check first was much better than the game 24. Kh1 Nc3 25. Bb2 Rf2 extremely complicated ) 24.

Carlsen tactics (Carlsen-Ding Liren 2020 Chess24.com Finals)

today I'd like to go over the game from Magnus Carlsen against Ding Liren, a sharp sicilian defense game.www.chess24.com for full coverage

Critical position 1:

Both players went into a dynamic types of positions ( Sicilian Najdorf by Ding Liren). with Kings on opposite sides. 

White to play in diagram above.

Hint: Magnus was looking at 27 Rf3 and 27Rf7+. Can you calculate the lines ?

Critical position 2 (analysis):

White had to evaluate 27Rf7+ Kf7 28 Qe6+ Kg7 leading to the following diagram, white to play.

can Black defend and what is White's best move ?

_____________________________________________________________________

Solution

_____________________________________________________________________

Magnus looked at 29 Qe7+ Kg8  30 Nxe5 but 30..Rh7! saves Black.

White would win by playing 29 Ne7! , and here's why:

if 29..Rab8 30 Qg6+ Kf8 31Rf1+ wins

if 29..Rh7 30 Rf1! Qc4 31 Qf7+ Kh8 32 Ng6 checkmate

if 29..Qxc4 30 Qg6+ Kf8 31 Nf5! Qe4+ 32 Ka1 wins.

in the game Magnus played 27Rf3 f5 28 gf6+ Nf6 29 Qg2 Qd7 which allowed Ding to come back into the game. But eventually Magnus won the game anyway.

Hikaru Nakamura wins against Danil Dubov on Magnus Final Tour tournament

 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 10Bf6

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 .
