Basic Strategy 7: Hand Discussion – 3

 

Another basic strategy article translated from the JPML site. Original link is at the bottom of the article.

 

Tanyao 断幺九 1 yaku

 

Keypoint: No 1s, 9s or honor tiles

 

☆  You can call to make this yaku (note: This is not permitted in EMA Rules)

 

A hand created entirely of tiles between 2 and 8 that goes out is a yaku.

 

Other yaku or dora will increase the score.

 

Pros

 

☆  You can go out even if your hand is not closed (note: This is not permitted in EMA Rules)

☆  You should be able to go out fast.

☆  If you combine it with dora, you can get a really high-value hand.

 

Good examples of when you should open your hand for tanyao.

 

–          You have two or more dora in your hand.

–          If you pon, you will be ready and have two or more potential winning tiles.

–          It is the last hand and winning will make you come top.

 

Cons

 

★  If someone reads your open hand, they will know that 1s, 9s and honor tiles are safe tiles.

★  If you call for your hand, you won’t be able to reach and thus your hand will be cheaper.

 

Ippeiko (Double Run) 一盃口 1 Yaku

 

Keypoint: Two runs exactly the same.

 

☆  Easy to make with other basic yaku.

★  You cannot have an open hand if you want to claim this yaku.

 

If you have two sets exactly the same and you go out, you have a yaku.

There are no other restrictions on the shape of your hand.

Other yaku or dora will increase the score.

 

Pros

☆This is a relatively easy yaku to make.

☆ The rest of your hand can be any shape, so you should be able to go out quickly.

☆ Combining it with pinfu and/or tanyao may get you a high-value hand.

 

Cons

★Ippeiko may not be a definite in your hand and it may be expensive or cheap.

 

A correct Ippeiko hand

An incorrect Ippeiko hand

 

   Ron:

 

Haitei (Bottom of the Sea)海底摸月 1 Yaku

 

Keypoint: Last Draw

 

☆  If you draw the last tile and win, you have a yaku even if you have an open hand.

 

A yaku is gained from drawing the Haitei tile (the last tile drawn) and winning with it.

There are no restrictions on the shape of your hand. Other yaku or dora will increase the score.

 

Houtei (Bottom of the River)河底撈魚 1 Yaku

 

Keypoint: Last Discard

 

☆  If you can win on the last discard, you have a yaku even if you have an open hand.

 

A yaku is gained from going out on the Houtei tile (the last discard).

There are no restrictions on the shape of your hand. Other yaku or dora will increase the score.

If you are not ready, you should be careful when making the last discard for this reason.

 

Rinshan (After a Kong) 嶺上開花 1 Yaku

 

Keypoint: Winning on a replacement tile after a kong

 

☆  If you win on the replacement tile drawn after declaring a kong, you gain a yaku.

★ You cannot combine this with Haitei or Ippatsu.

 

Chankan (Robbing a Kong) 槍槓 1 Yaku

 

Keypoint: Kong tile win

 

☆  You can gain a yaku if you win from the tile used to promote a pong to a kong.

 

Ippatsu 一発 1 Yaku

 

Keypoint: Immediate win after riichi

 

If you win in the first turn after your reach with no pongs, kongs or chis declared, you have a yaku.

If you draw the Ippatsu tile yourself, you will have riichi, ippatsu and tsumo for 3 yaku.

If you call for the Ippatsu tile, you have riichi and ippatsu for 2 yaku.

 

Dora  ドラ  1 Yaku each

 

The next tile after the Dora indicator tile is the dora.

Each dora in your hand counts for a 1 yaku score.

However, in the case that you have no yaku other than dora, you cannot go out.

This is the same in the case of ura dora (hidden dora) and kan dora (kong dora).

The ura dora indicator is the tile under the dora indicator.
