game 4 key moments

Position 1 after 17Nd3;Black to play

Karjakin

Carlsen

Carlsen just played 17Nd3

Solid position for white, controlling center and d5 square.

Karjakin tried to attack with..h5 

Position 2 after 34Nb5, Black to play

Karjakin

Carlsen

Here Black should play 34..Ra1 and its not clear what White should do. 35 Ra1 or 35 Kh1 waiting;
Instead 34..Rb3?! ran into 35 Nd4 forking Rook and Queen. White gains the exchange while still being in control

Black to play after 48 Kh1

Karjakin

Carlsen

Here Black played  48..Qf2?? which ran into 49Rc8+ Kh7 50 Qh6+!! Kh6 51 Rh8 Checkmate or gh6 51 Rf7 Checkmate

Black had to exchange queens but ending is riskless for white. The critical mistake was to sacrifice the exchange on move 34; 34..Ra1 was the only way to keep the game going for Black.

The final combination is easy to spot, and it is possible Karjakin saw it but went for anyway.

Game 3 Tie-Break key moments

Position 1: After 18 Ne4

Karjakin

 Carlsen

Carlsen found an excellent move 18..Qe8! bringing attacking chances on the kingside. Please note that Ba2 cannot cover light squares.

Position 2: after 22Qe2

Karjakin

 Carlsen

Carlsen found a good way to open a second front on queenside. 22..a5! putting pressure on queenside as well. 23 ab5 ab4; 23 ba5 Ra5;

Position 3: after 38 Rc7

Karjakin

Carlsen

38..Ra1! winnnig on the spot ; if queen move Nf1+ and checkmate follows.

game 2 key moment Carlsen-Karjakin

Position I after 19 Ra4, Black to play

Karjakin

 Carlsen

Karjakin played Bxe3. Magnus could recapture with 20 Re3 to protect pawn on e4.

Instead he went for 20 Be3!? Ra4 21 Qa4 Ne4 Karjakin takes the pawn 22 Rc1 Bd5 23 b5 !?

Here's the second key position, Black to play 23.. move

Karjakin

Carlsen

Karjakin went for 23..cb5 24 Qe4! Qc1 25 Qd5 which led to the 2 bishops versus rook ending with 3 pawns each.

If black had played 23..Nd6 White could play 24 b6 Qb7 25 Qb4 with some pressure. nothing clear though

23..Qd6 was possible, not sure if white should take on c6 or play for advantage 24b6.

23..c5? was bad since white could play 24Bc4! getting rid of the black bishop or 24Ng5!?

Karjakin decision led to an ending which was better for white. but in the position below , Carlsen failed to find  ( in rapid game with little time left) Be6+ followed by Bf8 which was leading to a win

Position after 72..Rb7?

He played 73 Bd6 but eventually Karjakin found a very nice save via a stalemate idea.

Magnus Carlsen remains World Champion after tie-break win 3-1

GM Carlsen remains the world chess champion.

Congrats !!
