Definiția și Sensul lui "undertrick"

What is an "undertrick"?

An undertrick in card games like bridge refers to any trick the declarer fails to win below the number required to fulfill their contract. For example, if the contract is to win nine tricks but the declarer wins only seven, the two missing tricks are undertricks. Each undertrick results in penalty points awarded to the defending side, with the severity of the penalty depending on various factors. Undertricks indicate that the declarer did not meet their bid.
