Acorn Jack

Also known as: Acorn Unter · Jack of Clubs

One card decides the deal: keep the Acorn Jack — or Jack of Clubs — off your tricks.

Objective

Avoid winning the trick that contains the Acorn Jack (Unter).

Special rule

Often paired with the 5th trick on the same deal. French-suited tables use the Jack of Clubs instead.

Scoring

A steep penalty for capturing that one card — sometimes split if it is combined with another target.
