Carlsen was pressing during the entire game but let the win escape

key positions

After 67 Re6!, Carlsen was winning

Karjakin(Black)

Carlsen(white)

Position after 67 Re6!

but after Carlsen chose the wrong plan with White, Karjakin could save the game here

Black to play :

                                                                      Karjakin(Black) to play

Carlsen(white)

Position after 70 Nc6

Black took on f5 with the king. Thats a blunder. 70..Rc3!! was eventually snatching the b3 pawn and the game would fizzle into N+R for white against R for black which is a theoretical draw. see pgn file for details. 70..Rb3?? 71Re6+ Kf5 72Nd4+ would lose. Karjakin missed this key move.

But in the following position, White played 72.Rb7?? and after 72..Ra1!!, Black was able to save the half-point. Great defense by Karjakin, and missed opportunity by Carlsen.

Position on 72nd move, White to play

Carlsen chose 72Rb7? here letting the win escape. 72Rf7+ followed by Rf2! using the white rook to defend against passed pawn h3 while hanging on to b3 pawn was key.
