Shanpon > Ryankan

For Beginner 15

South 2  Game,  South seat, 12 round,  32,400pt     Dora   

Answer

Commentary

Shanpon  (Double pair wait)  >  Ryankan（Gut shot)  

This is a form that I introduced once in For Beginner 8.

It is useful in the early and middle stages of the game, as it accepts 2 types of 8 tiles.

However, at the end of the game, you need to make the final form.

The final form is always the Ryan men (Double sided wait).

How can we wait for the "Ryan men"?

You should always be aware of the following.

In this hand, if you discard 4s, and take Ryan kan , the only change to Ryan men (double  sided) is only 3s.

But if you use the Souzu as the head, the Manzu can change to Ryan men.

If you discard the 8s, you can change this hand to Ryan men with 5m and 7m in addition to 3s.

Of course, if the triplet changes by drawing 6m or 4s, don't hesitate to call  Riich with 5 8p.

Can you guess where it is?

There are two of them.　Waiting for Ryangmen.

Dora to the edge

 For Begginer 14

Answer

Commentary

Bring the dora to the edge.

At first glance, it looks like you can discard either one.

It is likely to discard 4m, thinking that you can draw 8m for Triple sequences.

It is better to be prepared for drawing dora rather than to have a 50% probability of losing Triple sequences.

If you discard 4m and fix dora in the middle, you will have to discard the dora itself or discard  the dangerous 6p 7p when dora comes in the future.

If you discard 7m, you can discard South, which is comparatively safer, and also accept dora, which will turn into a hand where you can expect to get a Mangan(8000 points) at once.

Not only does it make the hand more expensive, but it also reduces the risk of dealing in with the dora to another player.

By keeping the dora at the end of the hand, you can always keep the dora in the hand.

The fastest way to make 2elements

For intermediate 6 

Answer

Commentary

The fastest way to make 2elements.

This is a loosing dealer.

You definitely must win this hand.

To make 5 blocks, you need to make 2 elements in Manzu(character), 1 element + head (or one more element) in pins(Dots), and 1 element (or head) in Sozu(Bamboo).

So you have to make 2 elements in Manzu.

If you discard 6m, this hand can accept 2m 3m 5m, 3 types 9 tiles.

If you discard ,  this hand can accept only 2m 5m, 2types 7 tiles.

Discarding 3m,  you can 2 elements by drawing 2m, 4m, 5m, and 7m, 4 types 12 tiles,

4 4 4 5 6 7 　

You should be able to consider this shape in your mind.

This is a losing dealer

Leave the suit with the larger number

For intermediate 6

Answer

Commentary

When you lost in choice, leave the suit with the larger number.

At first glance, they look the same, but there is a big difference when you draw the 5s.

Discard 7m

you are able to make ready hand when you draw 6s, 7s, and 5p

Discard 7s

you are able to make ready hand when you draw 7m and 5p.

Eventually, you have to choice 7m or 7s again. 

(In this hand, you had better to discard 7s, because  2 3 4 5 5 can change Ryan-men wait).

I think it's good to remember that in mahjong, when you can't dicede, leave the suit with the larger number.

Too hot day.

I have gone to beach, today.

Great sunset.

Tomorrow, Opening ceremony of Olympics is gonna be held. 

May it be a good day.

Calling Riich first in the early round is very strong regardless of the wait

For Advance 2 Mahjong soul

What would  you do ??

①  Call for Riich  by discarding 5s

②  Not for ready by discarding 8p

Answer

①　Should call for Riich

Commentary

Calling Riich first in the early round is very strong regardless of the wait.

First , the win rate and the Deal-in rate  when the player goes for riichi in this situation are shown in red letters of the figure.

The reason for discarding 8p here is to make a double-sided hand.

In order to make a double-sided hand, you need to draw five types of hands: 5p, 3 4 6 7s.

The probability of drawing one specific type of mahjong tile is about 3%.

So, the probability of this hand turning into a double-sided hand is 3 x 5=15% per one round.

So, on average, it will take 6 to 7 rounds for this hand to turn into a double-sided hand.

In other words, you can expect to reach double-sided riichi in the 10th or 11th round on average.

Therefore, we have to compare the probability of double-sided = blue letters.

However, this is the case when you proceed alone.

Taking into account other players

During this time, on average, 1.2 players have already made ready hand, so you have to take into account the possibility of calling riichi following other players.

The following table shows the Win rate and Deal in rate at that time.

In other words, it is most reasonable to compare the red letters in the table above with the blue letters in the table below.

Summary

If no one makes ready hand, there is not much difference, and if someone makes ready hand, you are at a disadvantage, so riichi is the way to go.

Awareness of 7 pairs

 

For Intermediate 4

Answer

Commentary

Blind Spot of 5 Blocks  - Awareness of 7 pairs - 

This hand is still two before for ready when considered in the normal 5-blocks (4 elements + 1 head). 

Moreover, you have to call either the green dragon, which is a dora, or the East, which is a double wind.

Moreover, the wait is either Kan-Chan (gut-shot) or Shan-Pon (doble-pair wait) .

Considering the round, it would be very difficult to win.

If you give up 5 blocks, you have one before for ready of 7 Pairs, and 9m is a good tile to waiting.

If you decide to play 7 pairs, you will have a good chance of winning with 9 tiles of 3 types in the hand.
