The first game was a marathon draw, lasting 7 hours. It was the fourth longest game in a world championship, after Game 5 of the 1978 championship (124 moves), Game 7 of the 2014 championship (122 moves), and Game 14 of the 1908 championship (119 moves). Caruana opened with 1.e4, and Carlsen responded with the Sicilian Defence, with Caruana playing the Rossolimo Variation, an opening with which he had lost against Carlsen in 2015. After 15 moves, it was clear that Carlsen had won the opening duel, with White having no clear way to improve his position while Black still had plans. Caruana started to consume a lot of time, but failed to neutralise Carlsen, with the result that Carlsen had a strong position after 30 moves and Caruana was in serious time trouble. Carlsen had a winning position several times between moves 34 and 40 but, despite a significant time advantage, failed each time to find the winning continuation, and after 40...Bxc3 Caruana was able to reach a drawn endgame. Carlsen continued to play for a win but Caruana was able to hold the game, despite being a pawn down in a rook endgame. The players finally agreed to a draw after 115 moves.
