Breaking news: Nakamura defeats Magnus Carlsen in day 1, game 2 for Magnus tour finals on chess24.com




Critical position where Magnus sacrificed the exchange on move 19 with 19Rg7?!




2nd Critical position where Hikaru played 36..Kg7 with a clear plan to activate rooks as indicated by arrows and explanation below. turning point of the game 2 with Hikaru(Black) in the driver seat

Colle-Zukertort Yusupov style d4,b3,Bb2 and Ne5

Opening prep

Showing a few lines about the Yusupov pet line d4,b3,Bb2 set-up

The system looks like this for White


The idea is to develop along these lines for white and pretty much go for the attack.
Good repertoire for blitz/rapid or even bullet.

and this is what it leads to when played right




__________________________________________________________
Lets see 4 critical positions

POSITION 2

and now the 4 games in full

Nakamura-Carlsen Game 4 Annotated Magnus Carlsen Invitational 2020

Hikaru with White must win to tie the match 2-2. He is trailing 1-2 in a rapid match of 4 games played online at chess24.com

First key moment
Black (Magnus) to play

Here Magnus saw that 16..c5 worked and would allow Black to equalize. Opening the position will favor the bishop pair.

Second key moment
White (Hikaru) to play 

Here Hikaru played 22bc5!? . He saw 22.Nc5 Nc5 23 bc5  Rdc8 with an extra pawn but the position has opposite bishops. Magnus would put his pieces on black pieces and his next moves would be easy to find. By playing 22bc5!? White keeps more pieces on the board.


Third key moment
White to play

Here Hikaru has an extra pawn and Knight versus Bishop instead of opposite bishops. Magnus drifted as the position was near equal around move 22. The position is now between draw and win for white and chess24.com commentators thought White had good chances to convert.
Here White rushed by playing 41.Ne5 on which Black played Bxe5 to enter the rook endgame. It was much stronger to play 41.a5 or 41 Kg2 to activate pieces. Black is passive and cannot start counterplay so White should improve his position patiently.


Fourth key moment
White to play

Here white played 43 Kg2?. This is a mistake from Hikaru as Magnus replied 43..g5 and later on ..h5 and ..g4. If Hikaru had played the best move 43 h4! , Magnus could have tried 43...h6  on which White would respond 44a5 g5 46 h5!. by not exchanging the h pawns, White would have another target the h6 pawn, on top of the threat of advancing the a pawn. This rook ending is winning for white.


in the end after 43 Kg2 g5! they continued but the game ended up in a draw by perpetual check. full game below.

9. dxc5 Bxc5 10. Bxc4 a6 11. Ng5 b5

Here's the  first key moment after 11..b5


Magus prepared this line and uncorked 12 Be6! fe6 13Ne6 forking the Queen and Rook. Magnus gets Rook and two versus Bishop and Knight.

Second key moment after 17..Qd5 : can you guess what White (Magnus) played ?

18 f3! The point is that White needs to get f3,e4 in motion and play 4 pawns versus 2. Giving the a2 pawn is no big deal, as the two pieces against rook will struggle against pawn advances.

Position after Queens were exchanged (24...Ne8). White to play: what is the best move ?

Here Magnus played 25 Bb4! Excellent move, as praised  by Alexander Grischuk on air (chess.24 commentary with Jan G and Peter Svidler). White locks down pawns a6 and b5 and gets ready to get his kingside pawns rolling. Nakamura said it was a brilliant move by Magnus in his stream recap.Chess engines evaluation don't reflect the fact  it is very hard to defend and save for Black.

 Position after 25.Bb4!


Magnus kept pressing and here's another key moment after 34..a5, White to play


Magnus spotted the best move 35 Rd5! attacking b5 and h5. Hikaru thought a5-a4 was a threat but White is in time to grab several pawns. Next moves were 35..a4? 36 Rxh5 Nef4 37 Rg5


Last key position after 44...Bd3, White to play :
Here Magnus played 45.Kg6! threatening h5-h6 and avoiding 45 e5? Kf7 with Black trying to achieve a blockade on dark squares.

White ended up winning the game in 52 moves , 2-1 in the match with Hikaru in a must-win situation with White in Game 4.

Carlsen-Nakamura Wijk 2011 Key Variation Explained

Example of GM Carlsen Attack:


Carlsen again Nakamura in 2011  played 30g7! what are ideas behind this move ?


Position after 30 g7! - Black to move

Carlsen-Nakamura Wijk Aan Zee 2011

Nakamura tried 30..Be7 31 Rh6 Nf7 32 Qg6! and lost quickly.
A) Whatif Naka simply tried 30..Bxg7 in the diagram above ? Carlsen would play 31Nf5 Rc7 32 Nh6+ with discovery checks to follow winning the queen
B) What happens after 30..Nf731 gf8+ Kf8 32 Nf5 Qe5 and we reach position Analysis I

White to play and win - Position I


Solution below
________________________________________________
------------------------------------------------
________________________________________________

33 Nh6!! leaving the queen en prise because of Rf7 with mate.

Position II after White's 33th move

33.. Rc7 34 Qg6! renewing the threat on f7 34..Qe6 35 Qh7! wins for White

The threat is Rhg1 and if 35..Ke7 36Re1! wins the queen on the e-column.


This is why Nakamura played 30..Be7 but lost anyway

King's Indian Defense & Attack by Hikaru Nakamaru today !




Fireworks start around move 20 ! A few comments on the following site:
http://www.chessgames.com/perl/chessgame?gid=1554908

I'd say that in the pure tradition of former world champs Robert J. Fischer and Gary K. Kasparov, Nakamura has now created his own KI Brilliancy !!



Beliavsky-Nakamura Amsterdam 2009 , after 28 Ba7
Black to play 28...?



You can play through older but classic King's Indian Defence games here, including the famous Kasparov wins against Korchnoi and Piket: http://games.top10chess.com/kingsindiandefence.htm

Quick attacking repertoire against the Pirc

A little introduction to the Austrian attack against the Pirc. Even though this blog is primarily focused on tactics, the following opening primer is geared at creating tactical and sharp positions from White's perspective.
It also gives supporting material to the tactical puzzle Nakamura-Smirin presented in an earlier post ( look for tag Nakamura to see previous Naka puzzles !)
http://www.top10chess.com/2008/05/tactical-quiz-easy-medium-level.html

1 e4 d6 2 d4 Nf6 3 Nc3 g6 4 f4 Bg7 5 Nf3



A) Black can simply castle here 5..0-0
6 e5 Nfd7 7 h4 !?
Start of the attack.



7..c5 8 h5 cd4 9 hg6 dc3 10 gf7+ Rf7 11 Bc4
This is the tabiya (key position) in this variation.


Here Black can play 11..Nf8 or 11..e6. Current theory suggests the latter is better.
The Nakamura-Smirin Foxwoods 2005 game featured 11..Nf8 with a spectacular win for White ( 22 moves !).

B)

5..c5 Black delays castle to react in the center

6 Bb5+



After 6..Bd7 7 Bd7+ Black can recapture in two different ways

B1)7.. Nbd7 8 d5 0-0 9 0-0 Ne8 10 Kh1

White has attacking prospects with f4-f5. See Le Quang-Gurevich 2008 for more.

B2)7.. Nfd7 8 d5 Na6 9 Qe2 0-0 10 0-0


White has a pleasant position. See Shirov-Hulak 1992 for more.



NOTE:
In Variation B ( 5..c5 6 Bb5+ Bd7 ), I chose 7 Bd7+ but the main theoretical move is 7 e5. Here's an important game for this continuation ( 18 f5 and 20 f6 are typical of this variation ):

IM versus GM, upset games

Once in a while, we see the underdog ( e.g. the lower rated player) win. Here are three games, where the International Master beats the Grandmaster. In each case, the rating difference is about 200 points, which makes the performance noteworthy. The games themselves are spectacular as well.
