The Jack of Diamonds Partner
The simplest partner rule in sheepshead, and the one most Wisconsin tables grew up on. Whoever holds the J♦ is the picker's partner. Nobody announces it, nobody chooses it, and it stays secret until the card hits the table.
The rule
- The picker takes the blind and buries, exactly as normal.
- Whoever holds the J♦ is secretly on the picker's side.
- The partnership is revealed only when the J♦ is played.
- If the picker holds the J♦, they are alone.
- If the picker buries it, they are also alone, and nobody else at the table knows that yet.
Why tables like it
There is no announcement, so there is nothing to read off the pick. In a called-ace game the call itself is information the whole table hears. Here the picker learns nothing extra, the defenders learn nothing extra, and everyone spends the first few tricks working out who is on which side from the cards alone. That hidden information is the entire appeal.
It also cannot fail. There is always exactly one jack of diamonds in the deck, so the partner rule never runs out of a card to point at. Call an ace needs two separate fallback rules for the hands where it breaks down, and this system needs none.
The awkward part
A picker who holds the J♦ is alone against four and knows it from the start. A picker who buries it is alone as well, and the defenders may spend the whole hand playing carefully around a partner who does not exist. Whether burying the jack is clever or reckless is one of the game's genuinely open arguments.
Playing your side well
The partner's job is knowing when to show up. Play the jack too early and you hand the defenders a map of the table. Sit on it too long and you leave the picker alone in exactly the trick where the help was needed. Timing that card is most of the skill in this variant, and the strategy page goes into when to spend it.
Play it here
Jack of diamonds is the default game on this site, and there is a standing J♦ table you can drop into without an account. If your group plays the other way, call an ace is a switch on any private table, and the variants page covers the rest.
