The way to deal with complex serial pair

At first glance, It seems equal to discarding 3p and 2s, in terms of both of them are 1-4 waiting.

The form of like this serial pair (which is one before for elements)  is called  "Complex serial pair".

Because these form can become either triplet or sequence.

From the point of view of this serial number as one before for sequence,  they are equal .

But if we see this serial pair as a pair to triplet, 2 is easier to call Pong than 3.

In this case, you have a 2 Dora, and player wind.

You should win this game by any means.

Had better call not only 1-4, but also 8m or 2s.

Exception of Chow theory

 

Answer

Commentary

Exception of Chow theory

In the yesterday's article, Chow theory is "Call a bad form and leave a good form".

Beginners may get confused, so be careful.

This form is similar to the form that is in yesterday's article, but in this case, you should not call Penchan, but Ryanmen.

If you call with 1 2p, the leftover form is below

This hand is ready for waiting with only 4 7p.

And if you call with 4 5p, you can wait by triple-sided wait (1-4-7p)

What difference are there in this case and yesterday's case ??

How do we think at calling ??

Of course, you should think case by case , but one principle is that, 

"Complicated single wait is the exception of Chow theory"   

This is worth remembering.

Call a bad form and leave a good form

 

Answer

Commentary

Call a bad form and leave a good form

Chow must  be done properly , and the way you do it can make a big difference.

Basically, chow should do "Call a bad form, and leave a good form".

Let's compare the leftover form.

call with ①1 2p

You can wait by Tripe-sided wait. (2-5-8)

But you call with ②4 5p

You wait for only double sided (5-8).

If you are not sure, you had better call with bad form like Penchan or Kanchan.

As a side note,  if you are not sure whether Pong or Chow, you had better call for Pong. 

(reference ; Pong or Chow??)

The other day, I have been hit the Tenho which probability is 1/330,000.

If you play 330000 games (about 30000 hard round), you can see.

If you play mahjong 10 times a day , it takes about 9 years.

I think this is too rare. 

Don't look to the difficult terminal or honor in every group

 

Answer

Commentary

Don't look to the difficult terminal or  honor in every group 

When you discard 1m and take Manzu part Ryanmen; 3 4 4m.

Your hand is still one before for ready, if this part is completed elements.

When you discard 4m, this hand back off to two before for ready.

In addition, If you draw 3m or 3p or 7p, this hand couldn't be completed to Terminal in every group at all.

In this hand, discarding 7p and look to not terminals or honor in every group but only three colors sequences.

And if you draw 9p , you should discard 4m and look to terminals.

Mahjong protects from depression

Prevalence of depressive symptoms and its related factors among China’s older adults in 2016

→ Full paper

Commentary

First, the impact factor of this journal (nealy the authority of this journal) is 4.88.

This is very high impact factor.

Why this paper is accept to published from this journal??

Maybe, this paper has very big samples.

In this study, 19420 people who are over 60 years old are analyzed.

They were screened  by Patient Health Questionnaire-9 

This score is from 0 to 27  and in this study,  19420 people assigned below two group according the test.

0~4  →　Non-DS (depression symptom)　group

5~27→　DS  group.

And analyzed the relationship with a lot of  items.

Result is below

People who play Mahjong and card game usually were not likely to have DS. (P-value<0.01) .

The ratio of Non-DS group with playing usually is smaller.

Other factors that people are not likely to have DS are 

・higher education 

・greater BMI

・living in urban areas

Conversely, the factors that people likely to have DS are

・Daily alchohl consumption

・Disturbed sleep 

・Chronic diseases

・Greater age

・Impaired cognition

・Poor ADL performance

 ・Insufficient social communication

So you should play mahjong in order to avoid suffer depression.

But never play  all night long and with drinking alchohl.

Always ready to draw more Dora

 

Answer

Commentary

Always ready to draw more Dora

The more you have, the better.

It is Dora.

If you call 4s with 2 3 , the rest elements is 4 5 6s.

Taking this form, you can't correspond to draw Dora.

But the rest elements is 2 3 4s, you can change 2s to 5s (=Dora that is your lover).

Don't miss the oppotunity of earning double point.

Be careful and don't hesitate

 From MahjongSoul

Answer

Commentary

Be careful and don't hesitate

In this situation, you must win this game.

But it isn't a rare to be careless and fall off the top.

What is the best option of this situation to win this game??

In this situation, you fall from top by dealer winning 6000 all or  your dealing in to dealer's 12000.

And, you can get the top even if you deal in to the Riichi by 16000 point (BaiMan).

Reducing the probability of 24000, I discarded green dragon(most safety tile) at the first round.

But this round, I must deal in to the opposite player to finish this game my staying the top.

So you discard the in a dangerous order. 

4-7 p that you can see 4 tiles is very likely to deal in. 

And then, 9m is the second. 

Next, 2-5s is dangerous.

The finish is below.

Incidentally, added the concealed Dora in this case, this hand get 12000.

But this Riichi usually has 8000 at a highest estimate.

Because he can rise to the order if his hand had 12000. He through my river and bet his own draw.
