This Friday begins the 2018 World Chess Championship in London. Reigning champion Magnus Carlsen of Norway takes on challenger Fabiano Caruana of the United States in a 12 game series scheduled to conclude November 26th, though tiebreaks could extend the series an extra day or two.

Carlsen, 27 years old, has held the title since defeating Viswanathan Anand of India in 2013. Caruana, 26, trails the current champion by just three rating points going in to the tournament (2835-2832) and is the first American World Champion challenger since Bobby Fischer in 1972.

For those not able to attend in-person, the World Championship games will be broadcast live online (3 PM GMT, 10 AM ET). A subscription to the series is only $20.

Don’t have someone to follow the games with? Consider Mates, the official World Chess Championship dating app. According to the app’s developer, “Good sex has a lot in common with a good game of chess… That’s why Mates limits your conversation to an hour, so you spend less time talking and more time playing.”

And if that doesn’t work for you, the tournament’s organizers have also signed an official online betting partner. Unibet expects wagers on the Chess championship to exceed those placed on some of the recent FIFA World Cup games. Odds are currently running ⅔-⅓ in favor of Carlsen.
