            "description": "瑞士制在選擇配位時最基本的一個原則是,挑選成績相同或最相近的選手進行比賽。\n\n第一輪比賽可通過抽籤決定或者根據賽前排名決定。比賽的勝者獲得1分積分,負者不得分,如果打平雙方各得0.5分(或勝兩分、和一分)。不管勝負如何,所有選手都進入下一輪。以後每一輪的配位,勝者對勝者,負者對負者,即根據此前的積分決定,積分相同或最相近的選手將相互對陣。當然前提是二者在前面的輪次中尚未交手過。在西洋棋比賽中,還要儘量使棋手執黑棋與執白棋的次數相等,普遍採用的辦法是輪換使用黑白棋。但不管怎樣,絕不能出現一名棋手連續3輪執一種顏色的情況。\n\n積分相同的選手配位基本規則是採用賽前排名編號,然後分成上下半區依次配對(如1號對5號,2號對6號...)。在必要的時候還要進一步調整以使棋手輪換先後手比賽,並保證此前相遇過的棋手不再相遇。\n\n具體的配位規則相當複雜,一般比賽的組織者都是通過特定的電腦程式幫助完成。只要嚴格執行,就不會出現組織者主觀制定配位的情況。\n\n比賽總輪次是賽前預先確定好的,一般為為3到9輪,最後的名次由選手的總積分決定。如果出現積分相等的情況,可以通過計算小分(如所有對手的積分總和)或布赫茲破同分法(Buchholz chess rating)決定。",
