All 12 scheduled games of the World Chess Championship have been completed, with neither Magnus Carlsen, the reigning champion, or Fabiano Caruana, the challenger, declared the winner. In fact, there was no winner in any one of the individual games.

The match will now move to four games of rapid Chess (25 minutes per player per game, plus 10 seconds per move). If there is no winner after that, there will be two games of blitz (5 minutes plus 3 seconds per move), followed by two more, and finally an Armageddon game, in which White gets an extra minute but Black wins on a draw.

In any case, a champion will be declared on Wednesday.

Drawn games are common in higher level play and the last World Championship also ended regular games at a tie. For the first time in the tournament’s history, however, all games played under classical time controls finished with a draw.

The last draw attracted some criticism for Carlsen, who offered it at the first opportunity (draws by mutual agreement are not permitted in the first 30 moves) despite being in a favorable, if somewhat complicated, position.

But it seems Carlsen was playing the game for a draw. Caruana, only 3 ratings points behind the champion in classic time controls, put up a good fight throughout the previous games. In rapid and blitz, however, Carlsen remains the top ranked player, while Caruana is number 10 and number 18, respectively. Carlsen apparently prefers his odds in these tighter games.
