# The hand must have a specific yaku confirmed before winning. In addition, when calling, it must have a specific yaku confirmed without needing to make another call and without needing the winning tile. (In most cases, this is equivalent to "you must confirm a yaku when you make the first call".)

If this hand wins from 6-sou, it gains [[iipeikou]]. If it wins from 9-sou, it gains [[sanshoku]]. When the atozuke rule is enabled, this hand can win no matter what. Both winning tiles give a yaku, so it always has a yaku, so it can win regardless of the tile. Likewise, when rule #2 is used, this hand is allowed to win.
If this hand wins from 6-sou, it gains [[iipeikou]]. If it wins from 9-sou, it gains [[sanshoku]]. When the atozuke rule is enabled, this hand can win no matter what: no matter which tile you win with, you'll have at least one yaku. Likewise, when rule #2 is used, this hand is allowed to win.


But when rule #1 is used, this hand cannot win. Neither iipeikou nor sanshoku are confirmed. Because this hand does not ''guarantee'' "iipeikou", "sanshoku", or any other specific yaku in its current state, it cannot win. (Of course, since this is a closed hand, you can just call [[riichi]].)
But when rule #1 is used, this hand cannot win. Iipeikou is not guaranteed, neither is sanshoku. Because the hand cannot guarantee any specific type of yaku in its current state, it cannot win. In this case, the hand is closed, so you just can call [[riichi]].


Note: when a yaku is not guaranteed because it is implied by another yaku, e.g. when a hand can score [[sanankou]] or [[suuankou]], atozuke does not apply, even when using rule #1.

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