In the ninth game, Carlsen held a difficult position with the Black pieces, then prevailed in the tenth game after a tense endgame. The score was level again. In game 11 Karjakin was unable to make an impression on the Norwegian and game 12 was an insipid draw that ended a little more than 30 minutes after it started. After nearly three weeks of play, the score was +1-1=10, and the match was heading into tiebreak games. Following is an excerpt from the official broadacst.
2016 FIDE World Chess Championship Magnus Carlsen vs Sergey Karjakin Game 12 (24:42) 'Press Conference Uncut'
Question to Karjakin just after the 12th game ended:-
Q: This was an extremely quick draw. Are you happy with that?
A: I played with Black, so maybe this is a question more to Magnus than to me.
Question to Carlsen a minute later:-
Q: Why did you decide to go into this quick draw?
A: I wanted to play a tiebreak. That's all I can say.
Q: Can you try to tell us why you want to do that?
A: We'll see [smiles].
As I write this, the tiebreak session is due to start in a a few hours. Today is also Carlsen's 26th birthday. It's well known that playing on one's birthday is psychologically difficult for most players, but Magnus is not like most players.
