... by: LudiIn order not to miss out on possible finned swordfish scenarios I would just like to confirm that I do understand the exact definition of this configuration correctly. Does the "fin" have to be the a second or third candidate in one of the defining columns (or rows) of the swordfish, or can it actually be a fourth candidate in a defining column (or row)?

The fin sticks out from the formation, so it is not one of the 9 candidate positions in the 3x3 formation. Ie, not one of the yellow cells in my examples. But it has to be aligned in the direction of the formation (so that it's absence would create a proper Sword-Fish). Hope that helps
