The eleventh game is now decided, and it was a draw.
Carlsen, with the black pieces, seemed to me to have a lot of play, and managed to advance a pawn all the way to the 7th rank.
But Karjakin was careful, and was able to force a draw by perpetual check.
So Monday will be the final game of the scheduled 12 games. If either player wins that game, that player wins the entire match.
But if they draw, then they will decide the championship by playing some more games, on Wednesday, using different time controls (faster and faster, until someone loses).
On we go!
