After giving a lot of thought to this thread I think I've come up with a technique to overarch everything we've discussed here: constraint subsets. It covers the skewed swordfish discussed here and other possibilities for larger sudoku. |

- or today we might write it thus -
Code: |
. * . | * . * | . . .
. * . | * . * | . . .
/ X / | X / / | / / /
-------+-------+-------
. * . | / / X | . . .
. * . | X / / | . . .
. * . | / / / | . . .
-------+-------+-------
/ X / | / / X | / / /
. * . | * . * | . . .
. * . | * . * | . . .
