'''Tanyao''' {{kana|断么九}} or {{kana|断幺九}} is a [[yaku]], | '''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. | ||
The tiles numbered from 2-8 are classed as '''chunchanhai''' {{kana|中張牌}}, or simples. Therefore, this hand may be referred to as "All Simples" in English. | |||

'''Kuitan''' {{kana|喰い断}} is a [[Rule_variations#Kuitan|rule allowing]] '''open tanyao'''. | '''Kuitan''' {{kana|喰い断}} is a [[Rule_variations#Kuitan|rule allowing]] '''open tanyao'''. If kuitan is disallowed, then it would be specified as "kuitan nashi", and tanyao would be restricted as a closed only yaku. If kuitan is allowed, it would be "kuitan ari", and open tanyao would be allowed. | ||
Tanyao takes special interest because it is fast, easy, and can be scored with many types of hand. With kuitan disabled, players are less likely to create cheap/fast 1-han hands. | |||
==Formation== | ==Formation== | ||
In order to form a hand with tanyao, players simply discard terminal and honor tiles. | |||
Even a hand cannot score tanyao, it's typically best to keep the "simple" tiles (2-8) over terminals/honors. This is because the simples are [[tile efficiency|more likely to be useful]]. | |||
*Lone honor tiles can only be used as a pair/triplet. | |||
*A lone 1 can be used in a 123 sequence, or as a pair/triplet. | |||
*A lone 3 can be used in a 123 or 234 or 345 sequence, or as a pair/triplet. | |||
Because the 3 can be used in more types of sequences, it is more likely to be useful. Therefore, lone terminals/honors are often discarded first. Because terminals/honors are discarded early, hands may "naturally" form tanyao without the player needing any special effort. | |||
It is generally unwise to force tanyao. If you already have a 789, for instance, then you probably shouldn't break the sequence. You may want to force it if you need a fast hand (and the hand can be completed quickly). | |||
===Open tanyao=== | |||
With open tanyao enabled, tanyao becomes even faster to develop. While a tanyao-only hand is not worth much, it is often quick. If you need ''a'' win - e.g., to end the game faster, or to break a tie - then 1100 points may be all you need. If tanyao is realistic, then call it. | |||
You may also wish to play open tanyao if you have multiple (2+) [[dora]]. In this case, dora provide value on their own; tanyao + 3 dora is already [[mangan]]. Therefore, 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. | |||
===Discard characteristics=== | ===Discard characteristics=== | ||
As the hand looks to keep the simples, the discards will be the converse: terminal and honor tiles. As mentioned above, though, terminals/honors are often discarded even for hands without tanyao. | |||
If a player has made multiple [[naki|calls]], none of those calls have a terminal or honor, and no other yaku is evident, then it is likely to be a tanyao. | |||

Tanyao is often combined with [[pinfu]]. The simple tiles are more likely to create sequences and more likely to create [[ryanmen]] waits. Therefore, hands aiming for pinfu will prefer simples, discarding terminals/honors, which can lead to tanyao. | |||
===Mentanpin=== | ===Mentanpin=== | ||
'''[[Mentanpin]]''' {{kana|メンタンピン}} is short for a hand with [[riichi]] + tanyao + [[pinfu]]. "Men" stands for menzen (closed, and by extension, in [[riichi]], not to be confused with [[menzen tsumo]]); "Tan" and "Pin" stand for tanyao and pinfu respectively. If the hand wins without riichi, then it is simply '''tanpin''' {{kana|タンピン}}. | |||
