Notes:

• There are two aspects to Acey Deucey:
  1. Identifying whether you are an End or a Center.
  2. Correctly doing your part.

  The Centers part is a Trade - from either a Mini-Wave or a Couple.

  The Ends part is a Circulate - move forward to the next position within the formation.

• Acey Deucey is not legal from formations where the End's Circulate path causes them to move into the center (e.g., Mini-Wave Columns, the In-Facing Ends' Circulate path would cause them to end in the center).
