Care for Ryanmen-Kanchan

At a first glance, 8m seems relatively safety.

But n case of declaring 2, 8 is dangerous.

Do you remember Ryanmen kanchan??

It is common to leave 2 till ready hand in Ryanmen-Kanchan.

And this hand, there is one more notable point one before declaring round.

North is Obviously "safety tile".

If you have Ryanmen and safty tile like below, you discard north ?? 

So 4m is relatively safe.

Of corse, 1-4 is dangerous, but 1 was discarded.

In this point of view, 3m is more dangerous than 4m.

But this hand, 1m was discarded in 4th round.

It is too early, to discard 1 from 1 1 2 2.

This hand has called for Riich by this hand.

Statistics of mahjong

 

Answer

Commentary

"Perfect" one before for ready

The form composed by complex serial pair ＋Ryanmen is called  "perfect one before for ready"

In addition to Ryanmen, there is acceptance to make triplet.

There is 4 tiles more than Ryanmen-Ryanmen one before for ready.

But recently, it is calculated that this advantage is too little.    (reffernce ; this book)

Especially, the part of complex serial pair is 4 5 6 like this case exceed the risk of leaving the tile.

If other player call for Riichi, you have to discard 6 (in this case) to the Riich in order to call Riich.

Ryanmen-Ryanmen wait for 16 tiles.

And this perfect one before for ready wait for 20 tiles.

In 16/20 case, Ryanmen is complete first.

And statistics reveal the risk exceed to the merit of leaving dangerous tile till ready hand.

The timing of discarding the safety tile

 

Answer

Commentary

The timing of discarding the safety tile

Why this player keep North that had already been discarded at 2 round till ready hand.

This is "safety tile"  in case other player call for Riichi.

Safety tile reduce acceptance of hand, so it must not deal in by the tile.

Choose the most safety tile, for example, the last tile of honors tile.

And the declaring tile is safety tile, the hand is likely to wait by Ryanmen.

If you have Ryan-kan and Ryanmen like

Do you discard 6s in this hand?? 

You can think "Declaring with safety tile means, the hand is Ryamnen"

See through the cheating line (Suji cheating ; suji hikkake)

Answer

Commentary

See through the cheating line (Suji cheating ; suji hikkake) 

This hand is not so no outstanding feature.

Maybe flat hand or so.

All of the option; 8p , 7s, 5m  are Suji of 5p, 4s, 5m.

Which is the most safety and which is the most dangerous ??

This is very simple, and you have to remember that.

"The later in round, the more dangerous".

All of players would like to wait by Ryanmmmen.

So all players want to complete Kanchan.

Ryankan is not likely to discard till ready hand.

Early discarding 5p imply the player have 2p of 8p, and 1-4 or 6-9.

Triple sequence (Three colors)

 

Answer

Commentary

River of triple sequence (three color sequence)

All suits are evenly discarded.

But looking well, there are no tiles under 5.

In this pattern, you should suspect of triple sequences of under suits.

Particularly,  Discarding 6, and Kanchan (gut shot) waiting for 3 from 2 4 6 is one of the most fliquentry.

Because, it is line cheating (suji cheating) , 3 is easily to get. 

And, if you draw 5, one of four tiles is red dora.

If you have 5 6 6 , it is too early to discard 7m. 

In this case, you may leave possibility of triple sequence of 5 6 7.

Perceive and correspond Terminal

Answer

Commentary

Perceive and correspond Terminal

There are many middle tiles in early round.

And later, gradually honor and terminal related tiles.

This imply that the hand is terminal or honor in every group.

It reach the half, if you can tell the hand is it.

You have to tell what tile is safer and what is  risky.

What is the situation of calling Riichi with discarding 8  in terminal in every group??

Most frequently case is from honor pair and end tile, like D D 8 9 9 →　D D 9 9.

So you have to care for discarding honor tiles and the next end tile.

How about 7 ??

If you have 8 8 9, you keep 8 till ready hand ??

If you draw 8, and complete 8 8 8 triplet, you loss the terminal in every group.

So this consequence, you may fix 8 9 in early round.

Watch out the Flash

 

Answer

Commentary

This river is discarded only 2 suits first, and then, honor tiles is discarded.

This pattern have to watch out the flash.

Especially, when the player calling Riichi, honor tile is dangerou.

The player prepared to be found out the hand is flash.

In spite of this, the call for ready means the player is confidence.

Or, to make other player fall  even if you don't win, other player.

West is most dangerous, and of course, 5s is dangerous.

Correspondance to 7 pairs

 

Answer

Commentary 

perceive the 7 pairs !!

This is a typical river of 7 pairs.

It is rare to diced making 7 pairs at the dealing.

There is a turning point, and before then, honors tile and terminal tiles are discarded.

In this hand,  turning point may be 4th round.

And it is strange that, to discard 8p after 6p discard directory.

And, 5 declaring riich is often the case in 7 pairs.

Because there is Red Dora.

In this reason, if you think the other player make 7 pairs, you should know 5 is danger.

Of course, West is very danger to 7 pairs.

3-7 suits is relatively safe in early Riichi of 7 pairs.

but it is a little bit risky at end of the game.

There is no reason of waiting 3-7 suits in early round.

The timing of discarding the center

 

Answer

Commentary

Risk is changeable depends on the timing of discarding

Last time, early discarding the center is dangerous for dealing with 1-4, or 6-9.

→Meaning of early discarding the center tile

This is atypical but kind of called "Ura-Suji ;  back line.

 How about late discarding the center ??

Frequent case is below 2 pattern.

 

①　Attached Ready

One of it is called " Kuttsuki Tenpin"  (Attached Ready).

This form is leaving isolate 3〜7 suit until late.

like below,

This hand accept 3〜7p , and 2〜6s, to ready hand.

It is little bit difficult to read where is wated.

②　Cross Line  (Matagi Suji)

Another is called  " Matagi Suji" (Cross line)

This form is making serial pair and then, fix Ryanmen. 

like below

This case, it is easy to read where to wait.

It is 3-6 or 4-7.

If you have 5 7 8, you discard 5 in early round, usually.

In this way, the timing off discarding is important to read.

That change the hazard level.

Meaning of early discarding the center tile

 

Answer

Commentary

Meaning of early discarding the center tile

Think why this player discarding 5p in the 2 round ??

What situation would you do that ??

When does the player knowing the efficiency discard the center tile within 3 round ??

The answer is when you have the Ryanmen serial pair include the line tile of the center tile.

For example, is you have 2 3 5, you don't need 5 even though the early round.

This theory is conversed the how to choice the terminal tile.

And in this case, it is very rare to deal in with 3.

If you have 4 5 5,  do you discard 5 at 2 round ??

So the player who make this river may not have 4 5.

Needless to say, the player can't have Gut shot waiting for 3.

Anyone  doesn't discard 5 from 2 4 5. Everyone  living on earth discard 2 from this.

Pen-chan is also not likely.

Good player may leave 5 from 1 2 5, in order to discard Pecan in the endgame.

In this hand, if you deal in with 3, the player have to wait single wait or pair wait.

Pair wait that is 1 1m  3 3p waiting  is possible in this river.

But 9p is more dangerous definitely.

Don't give up 7 pairs

 

Answer

Commentary

This hand is differ form yesterday's hand  by only one tile.

But there is Dora in this hand and 5 pairs that is one before for ready.

In this case, you should give up looking to 7 pairs.

There's a big difference between having one and not having one.

When you win by 7 pairs with dora × 2 is very big hand that is Haneman; (12000).

It is very bid damage, when you discard 3m or 7s , and draw west (Dora).

When you draw 7m, you should call for Riichi waiting for DORA.

If you draw 8s, you had better not to call for Riichi, also waiting for DORA.

Because, If you 1-4m, you gotta consider the flat hand and double sequence.

It is　still strong to wait Ramen.
