When the atozuke rule is disabled, the hand must have a confirmed yaku before winning. There are two main variations to atozuke disabled:


# The hand must have a specific yaku confirmed before winning and before calling any tile. Therefore, a hand that could always win with atozuke enabled may not be allowed to win.
# The hand must have a specific yaku confirmed before winning. In addition, when calling, it must have a specific yaku confirmed once the call completes.
# The hand must have a yaku no matter which tile it wins on. Any hand that always has a yaku can win.
# The hand must have a yaku no matter which tile it wins on. Any hand that always has a yaku can win.

This hand has a confirmed yaku through the triplet of hatsu. However, ''it did not have any yaku when calling the 789-sou''. Therefore, this hand cannot win when rule #1 is in effect. In rule #2, this hand can win normally.

When the hatsu triplet is closed, the hand can always win, even under rule #1. (Even if the hatsu triplet was not there when 789-sou was called, there would be practically no way to enforce it, so "drawing the hatsu triplet after calling" play is technically allowed.)

Note: for whole hand yaku, like [[honitsu]], the yaku can be scored even if the yaku wasn't complete at the time of calling. Similarly, calling for [[chanta]]/[[junchan]] is allowed so long as your final wait guarantees the yaku.
Note: for whole hand yaku, like [[honitsu]], the yaku can be scored even if you had no other yaku and the yaku wasn't complete at the time of calling. Similarly, calling for [[chanta]]/[[junchan]] is allowed so long as your final wait guarantees the yaku. However, you cannot have a [[kanchan]] of 24-man to complete a 234 sanshoku if sanshoku would be your only yaku.
