Takume and yasume can be important when deciding whether to [[riichi]] or stay [[damaten]].
Takume and yasume can occasionally be important when deciding whether to [[riichi]] or stay [[damaten]], due to the differences in [[furiten]] rules:
*If a [[damaten]] hand rejects a [[ron]], it only enters [[furiten]] until your next turn.
*If a [[damaten]] hand rejects a [[ron]], it only enters furiten until your next turn.
*If a [[riichi]] hand rejects a ron, it enters [[furiten]] permanently.
*If a [[riichi]] hand rejects a ron, it enters furiten permanently.


Thus, a dama hand may reject an opponent's discarded yasume and wait for a more valuable tile. However, because riichi is worth ~1.5 han on average, you should not dama just because you can decline a yasume. For example:

Overall, for this hand, riichi can accept twice as many tiles, with a minimum expected value of 2.5 han. Dama can accept half as many tiles, for a value of only 3 han. Therefore, riichi is better. The difference between takume/yasume should be 3+ han to be considered, and even then, you might want to riichi.
Riichi has a minimum expected value of 2.5 han. Dama can accept half as many tiles, and only scores 3 han. Therefore, riichi is better. The difference between the takume/yasume needs to be 3+ han to be net positive, and even then, you might want to riichi.


Takume and yasume can be relevant in [[oorasu|all last]] (where only the takume could let you rise a rank).
