The Zurich Chess Challenge is one of the major recurring international chess tournaments, combining rapid chess with classical or blitz chess. Zurich shows an exhibition type of tournament, similar at the former Amber chess tournament ambience, which explains some laxness and a comparatively brief duration of the whole event. It takes place in Zurich, Switzerland. The main sponsor is Russian businessman Oleg Skvortsov.
The Zurich Chess Challenge 2014 took place from 29 January to 4 February 2014. The average rating of its participants is 2801, the highest ever at the time, and it is also the first category 23 tournament ever. Magnus Carlsen won the tournament. The opening day included five rounds of blitz to decide the draw, which was won by Carlsen. The main tournament consists of five rounds of classical chess and finally five rounds of rapid chess on the closure day.

For games that ended in a draw in under 40 moves, a subsequent rapid game between the two players was mandatory, although these particular rapid games had no relevance to the tournament standings. Two such games were played: Gelfand–Aronian in the third round and Gelfand–Nakamura in the fifth round.

The tournament was held from 13-19 February 2015 at the Hotel Savoy Baur en Ville in Zurich. A Blitz Tournament determined the colors distribution on the first day of the tournament. After the opening, 5 classical games were played following by another 5 rapid games on the last day of the tournament. The rules stated that wins and draws count double for classical games, with a draw before move 40 “punished” by an extra rapid game. Vishy Anand and Hikaru Nakamura ended up with 9 points. For determining the winner, although it was said before that the previous games between two must decide the result, they changed the rules midway and asked the players to play an armageddon game in which Hikaru Nakamura won with the black and ended up as the tournament winner.
