Kan is an offensive move. The player gets an extra draw from the [[rinshanpai]] and chances for the kandora. If the hand is tenpai, then the hand has a chance for [[rinshan kaihou]]. | Kan is usually an offensive move. The player gets an extra draw from the [[rinshanpai]] and chances for the kandora.

Most importantly, if the kan-declaring player wins, then their opponents will not benefit from the kan dora. Therefore, if the player believes that they are likely to win the hand (e.g. reaching [[tenpai]] early, or [[iishanten]] very early), then kan is stronger than usual. | Most importantly, if the kan-declaring player wins, then their opponents will not benefit from the kan dora.

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, if kan is possible during riichi, then it will often be done. | 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. | |||
When playing with real tiles, players must always be aware of whether a kan call can [[Kan#Restrictions|legally be called]]. Players using game software or online platforms do not need to be aware because the programs handle the situations for them. | When playing with real tiles, players must always be aware of whether a kan call can [[Kan#Restrictions|legally be called]].

Any player can apply [[kabe]] when somebody calls kan. If all four tiles are visible, e.g. from an opponent's kan call, then it will make certain types of wait impossible. For example, If a kan of 3 is called, then the wait patterns of 23, 34, and 13 of the same suit are impossible. Thus, 1 and 4 become safer. If all four tiles are in your own hand, then there's no need to actually call kan in order to benefit from kabe. | Any player can apply [[kabe]] when somebody calls kan.

If you have no safe tiles, a possible play is to call kan and hopes to draw a safe tile. However, since you'll likely increase the score of the opponent, this is a weak play. In addition, the kan tile could become safe later (e.g. becoming [[suji]]), and then you will lose four tiles. Therefore, you should try avoiding this unless it's late into the hand. | |||
