In chess, each player is pitted (paired) against another player with an equivalent performance score. In "Round 1" of a chess tournament paired using the Swiss System, players usually are seeded according to their known playing strength, for example their "chess rating" assigned to them by their local club, their national federation, or the world chess federation (FIDE). In some events, especially when none or few of the players have an official chess rating, the players are paired randomly. Once play begins, players who win receive a point, those who draw receive one-half of a point, and those who lose receive no points. Win, lose or draw, all players proceed to the next round where winners are pitted against opponents with equal performance scores (e.g. Round 1's winners play each other, Round 1's draws play each other, etc.). In later rounds (typical tournaments have anywhere from 3-9 rounds), players face opponents with the same (or almost the same) score. No player is paired up against the same opponent twice.
