With today as a rest day, play resumes tomorrow Saturday in the crucial Round 11, when Karjakin will have the White pieces. There then follows another rest day on Sunday, with the final round being played on Monday.
If the score is tied after 12 rounds, there will be a series of tie-break games on Wednesday. Four games will be played with 25 minutes for each player with an increment of 10 seconds per move. If the score is still tied, there will then be a series of two-game blitz matches played at the rate of five minutes plus five seconds increment. These will continue for up to five 'matches', eg ten games, until there is a winner.
In the unlikely event of the scores still being tied, a final sudden-death 'Armageddon' game will be played. The player who wins the drawing of lots chooses the colour. The player with the White pieces receives five minutes, whilst the player with the Black pieces has four minutes. A three-second increment per move is applied if the game continues beyond 60 moves. In the event of the game being drawn, the player with the Black pieces is declared the winner.
Wednesday could be a fun day. So cancel all other arrangements!
