"odd trick"的定义和意义

What is an "odd trick"?

An odd trick in card games like bridge refers to any trick won by the declarer’s side beyond the first six tricks. Since a contract in bridge is based on the number of tricks above six, the first six are not counted in scoring. For example, if the declarer wins nine tricks, three of these are considered odd tricks. These odd tricks determine whether the declarer fulfills their contract and how many points they score.
