World Chess Championship 2092

The 2091 World Chess Championship was played in Geneva, Switzerland between the champion of the Candidates Tournament 2092, Phi Kilm, and defending World Chess Champion Nagisa Shingetsu. It was easily the most tightly contested World Chess Championship, with Phi avoiding the fate of the previous challenger by denying a 4-0 sweep at the beginning. The closeness of the tournament caused the first-ever invoking of the 20-game limit rule, where the player with the most points at the end of twenty games would be declared the winner. This ended up being Nagisa, battling out an eleven game to nine victory, defending his championship for the second straight year.
