Players in riichi benefit from twice the dora: a kan dora and a kan ura dora. Also, a player in riichi is already in tenpai, so they become more likely to win. In addition, the threat of kan dora will make your riichi more threatening. Therefore, | Players in riichi benefit from twice the dora: a kan dora and a kan ura dora.

If you are in riichi, but someone appears to be pushing against you, it becomes a more risky play. If you happen to be in the lead in this situation, consider not calling kan. | If you are in riichi, but someone appears to be pushing against you, it becomes a more risky play.

This gives | Kan is not mandatory, so players do not have to call kan immediately. Instead, they can keep the fourth tile in their hand, declaring kan if/when appropriate. This gives more flexibility - e.g., if an opponent declares riichi on the next turn, you will be glad that you did not kan. However, delaying the kan willl reduce tile efficiency (if you are not using the tile for the hand). | ||
Under most circumstances, you should not call kan if it would break up a sequence. For example, if you have a 555567 in your hand, it can be considered as two groups: 555 + 567. Calling kan would ruin the 567 sequence, thus slowing down your hand. But if you then draw the 8, then the sequence is retained, so kan no longer slows the hand. | Under most circumstances, you should not call kan if it would break up a sequence.
