Condition List:
- 11EmptyDifferent: Because this is an empty siding fork the rotatable empty (re) position of the first pattern is by definition on a different column than the re of the second pattern. In other words their re's must be on different siding columns, not be sharing a column. As such the fork is effective because the opponent can only defend on one of the two re0 leaving one re0ppp for the player to win.
