To repeat, the atozuke rule is most often enabled. When atozuke is enabled, all of the following types of hand can win without issue. | |||
=== Two different yaku=== | |||
{{#mjt:789m789p67878s55z}} Agari: {{#mjt:6s}} or {{#mjt:9s}} | {{#mjt:789m789p67878s55z}} Agari: {{#mjt:6s}} or {{#mjt:9s}} | ||
If this hand wins from 6-sou, it gains [[iipeikou]]. If it wins from 9-sou, it gains [[sanshoku]]. | 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. | ||
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. Neither iipeikou nor sanshoku are confirmed.

This hand would gain a yakuhai triplet if it wins off the haku or chun. However, it does not have any yaku in the current state, and so it cannot win if rule #1 is in effect. | This hand would gain a yakuhai triplet if it wins off the haku or chun.

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. | This hand has a confirmed yaku through the triplet of hatsu. However, ''it did not have any yaku when calling the 789-sou''.

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.) | When the hatsu triplet is closed, the hand can always win, even under rule #1.

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. | |||
