Chess games that are played with one player without the full amount of pieces are said to be played at odds. They are played so that one player that is weak can beat somebody stronger. You do not see these games much now bet a lot in the old days, when a good player played an amateur. When a game is played without one side having a queen then it is called queen odds. Without a rook is rook odds... here is a game played at queen odds.In this game the queenless William Norwood Potter defeated an amateur. Even though the amateur was horrible, you still have to admit he was an experienced player. Hope you enjoyed this article, and hope you read my other ones. Feel free to edit and comment.
