'''Tanyao''' {{kana|断么九}} or {{kana|断幺九}} is a [[yaku]], obtained when the hand only has numbered tiles 2-8 from any of the [[Mahjong equipment#Japanese tiles|three main suits]]. By proxy, the hand cannot contain [[Routouhai|terminal tiles]] (1 and 9) or [[Jihai|honor tiles]]. It is one of the faster and easier yaku to obtain, though it is cheap. Depending on the ruleset, you [[#Kuitan|may or may not]] be allowed to score this yaku when the hand is open. | '''Tanyao''' {{kana|断么九}} or {{kana|断幺九}} is a [[yaku]], obtained when the hand only has numbered tiles 2-8 from any of the [[Mahjong equipment#Japanese tiles|three main suits]].

The tiles numbered from 2-8 are classed as '''chunchanhai''' {{kana|中張牌}}, or simples.

Even a hand cannot score tanyao, it's typically best to keep the "simple" tiles (2-8) over terminals/honors.

It might be unwise to force tanyao. If you already have a 789 sequence, for instance, then you probably shouldn't break it. However, if open tanyao is allowed, you may want to force tanyao if you need a fast hand (and the hand can be completed quickly). | |||

When open tanyao is allowed, this yaku is notoriously fast. While a tanyao-only hand is not worth much, it can be quick. If you need ''a'' win - for example, to end the game faster, or to break a tie - then 1100 points might be all you need. In these cases, if tanyao is realistic, then call it. Depending on the hand, though, it may be faster to play [[yakuhai]] or (if the hand has completed groups with terminals) play closed. | |||
You may also wish to play open tanyao if you have multiple (2+) [[dora]]. | You may also wish to play open tanyao if you have multiple (2+) [[dora]]. Here, the dora provide value on their own; tanyao + 3 dora is already [[mangan]]. Therefore, with multiple dora, you should call to speed up the already-valuable hand. If the dora are closed within the hand, then there is the added deceptiveness of your hand being a cheap hand, when in reality this is not the case. | ||
