'''Nakasuji''' {{kana|中筋}} is literally the "middle suji"; it refers to a 4/5/6 tile when both tiles in its suji interval have been discarded before. | '''Nakasuji''' {{kana|中筋}} is literally the "middle suji"; it refers to a 4/5/6 tile when both tiles in its suji interval have been discarded before. | ||
As mentioned above, the middle tiles (4,5,6) have two suji intervals to account for. A 4 has two suji intervals, 1-4 and 4-7. A discarded 1 does not make 4 much safer, because an opponent could still have a 4-7 ryanmen wait. In order for 4 to be a "full" suji, both 1 and 7 have to be safe. | As mentioned above, the middle tiles (4,5,6) have two suji intervals to account for. A 4 has two suji intervals, 1-4 and 4-7.

So, if both 1 and 7 have been discarded, 4 is called a nakasuji tile. | ||
