Two numbers in the middle can finish a Run two ways. At the edge, only one way.
Takeaway: Middle pairs of numbers finish two ways.
In Mahjong Island, two tiles in a row from the middle finish a Run two ways. 4 and 5 Bamboo take a 3 or a 6.
At the edge, there's only one way. 8 and 9 Bamboo need a 7, because nothing comes after 9.
So when you're choosing what to keep, two middle tiles beat two at the edge.
