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.

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