In short: a tile | In short: a tile becomes safer against an opponent if they've discarded every tile (of the same suit) that is an interval of 3 from that tile. For example, if an opponent had discarded a 4, then both 1 and 7 of the same suit are safer. If an opponent discarded both 1 and 7, then the 4 becomes safer. (If an opponent had only discarded a 1, the 4 is not much safer.) | ||

The reason ura suji is not that much more dangerous than normal is because it assumes a (35) kanchan had existed in the first place. The 5-pin could have been an unrelated tile, or it could have been part of a 57 kanchan, or part of a completed 556 shape, or part of a completed 135 shape, etc. Even if the kanchan did exist, an opponent could have | The reason ura suji is not that much more dangerous than normal is because it assumes a (35) kanchan had existed in the first place.
