Gameplay
Jack of Diamonds (J♦)
Definition
The lowest Jack in trump order and the partner-designating card in the JD partner variant. In standard Called Ace, J♦ is just the weakest Jack; in JD games, it carries the same secret-partner role that the called Ace plays in standard rules.

A partner-call variant where the holder of the Jack of Diamonds (J♦) is automatically the picker's partner, instead of the picker naming an Ace. Popular in some Wisconsin tables because it removes the void-suit guessing game.
Partner
The player holding the called Ace who teams up with the picker. The partner's identity is secret until the called Ace is played.
Trump
The powerful suit that beats all fail cards. In Sheepshead: all Queens, all Jacks, and all Diamonds are trump (14 cards total).
