Magnus Carlsen and Fabiano Caruana draw in Game 12 – live! Read more

The latest bloodless result, the 12th draw between the world’s top two players in as many contests, ensured the €1m ($1.14m) showdown in London will go down as the first title match in which no decisive results were managed in the official 132-year history of world championship play.

“I wasn’t necessarily going for the maximum,” said Carlsen, who all but admitted he was content to move directly to a tie-breaker after move 20. “I just wanted a position that was completely safe, [but] where I could put some pressure. If a draw hadn’t been a satisfactory result, obviously I would have approached it differently.”

The 27-year-old champion from Norway, making his third defence of the title he captured from Viswanathan Anand in 2013, will play as white in Wednesday’s first tiebreak stage after a drawing of lots following Monday’s game. The tiebreak will consist of a best-of-four rapid match with 25 minutes for each player with an increment of 10 seconds after each move. If that is not enough to break the deadlock, they will play up to five mini-matches of two blitz games (five minutes for each player with a three-second increment). If all five mini-matches are drawn, it will come down to one sudden-death ‘Armageddon’ match in which white receives five minutes, black receives four minutes and both will receive a three-second increment after the 60th move. If that game is drawn, black will be declared the winner.

Carlsen, who in addition to his No 1 ranking is the world’s top-rated rapid player and top-rated blitz player (compared to Caruana’s respective ratings of No 8 and No 16), is widely regarded as a strong favorite in the format, not least due to a 13-year unbeaten record in tie-breakers. But Garry Kasparov said on Monday that Carlsen’s hasty draw offer betrayed a lapse of nerve in the reigning champion.

“In light of this shocking draw offer from Magnus in a superior position with more time, I reconsider my evaluation of him being the favorite in rapids,” the longtime world No 1 wrote on Twitter. “Tiebreaks require tremendous nerves and he seems to be losing his.”

Caruana, as white, played into the Sveshnikov variation in Monday’s classical finale, as he did in the eighth and 10th games. Carlsen was first to deviate from those lines with 8. ... Ne7 and Caruana quickly fell behind on time after the champion played a novelty with 12. ... h5.

Game 12 was a draw after 31 moves and nearly three hours.

The 26-year-old American challenger was offered a chance for a draw by repetition shortly after (13. Qa4 Bd7 14. Qb4 Bf5) but bravely opted to play on with 15. Be3. Yet Caruana’s temporal problems compounded over the next few moves (15. ... a6 16. Nc3 Qc7 17. g3 Be7 18. f3 Nf8 19. Ne4 Nd7 20. Bd3) and he soon found himself nearly 50 minutes behind on the clock.

After Carlsen castled following a 12-minute think (20. ... O-O), Caruana delivered a surprise move (21. Rh2!?) that cost him in the opinion of the evaluation engines, but earned praise from the Russian grandmaster Alexander Grischuk from the commentary booth: “The deepest move in the match so far,” he said.

Even after the champion expended another 10 minutes before playing 21. ... Rac8, Carlsen was ahead in development with more than a half-hour advantage in time. He pressed the initiative with 22. ... Bg6 23. Rc2 f5 and Caruana’s dubious 25. f4 sent the computers haywire. The challenger’s position appeared increasingly difficult to hold after 26. ... e4 27. Be2 Be8 28. Kb1 Bf6 29. Re1 a4 30. Qb4 g6.

Which made Carlsen’s decision to offer a draw after 31. Rd1 Ra8 nothing short of mystifying. A relieved Caruana gladly accepted after a game that had lasted two hours and 57 minutes, sending the match to Wednesday’s tie-breaker.

“I was a bit surprised by the draw offer,” said Caruana, who is looking to become the second American-born player to capture the world championship after Bobby Fischer in 1972. “I can never be better [than move 31]. And I don’t really have any active ideas. If anything, black is better. At least I thought I was over the worst of it. I thought it was much more dangerous a few moves ago.”

He added: “I’m mainly relieved because I thought it was quite close today. I was very worried during the game. When you feel like you’re sort of on the brink of defeat, or at least you have a very dangerous position, then of course it’s quite good.”

Both players bristled at the notion that a world title match consisting solely of draws could undercut the sport’s popularity, addressing the central talking point of their three-week psychodrama.

“We work with the match that we have,” Caruana said. “If the powers that be want to change it, then we’ll work with something else.”
