Meaning of discarding 2 in early round

 

Answer

Safe tile    

Dangerous tile

Commentary

Meaning of discarding 2 in early round

The first three rounds of the game are very informative.

The meaning of discarding 2 is that

① Dosen't wait for 1-4m

②Very probable to have 5m

① depends on the round of call for Riichi.

In case discarding 2m at 2 round but calling Riichi at 4 round, 1-4m is dangerous.

This hand, ①＋② → 4-7m or 3-6m is most dangerous.

Bad form is OK If you have a valuable tile

 

Answer 

Commentary

Contrary last article, triplet of 8p replaced valuable tile.

You should discard 5s  in this case.

Because you can chow 3s or pong 9p or 1s when necessity arises.

You can win this game in early round.

But, you had better not to discard East here, too.

Answer

Commentary

There are 3 pairs ＋ 1 triplet in this hand.

You never exclude 7 pairs and All triplets, finally 4 concealed triplets.

SO you must not discard 4m, and east.

East is only one tile so far but it is important because you are east seat.

If you draw one more wast, your hand get more 2 roles so called double-east.

And win by All triplets＋Double east, you get 8000 points.

4p and 5s have possibility to triple sequences, 3 4 5 or 4 5 6.

2s is most useless.

If you draw 3s in early round, you can't get any role, even flat hand.

If you draw

3m (Dora) 　　　→  Riichi ＋Dora

East          　　　→  All triplet

One more pair　  → 7 pairs

3 4 5p or s            →Triple sequences

 

leaving 2s is most halfway.

This is a fried rice of "Ippudo"

I love pork soup Ramen very very much, as a matter of fact, Fried rice of Ippudo is really delicious rather than Ramen.

Hot TAKANA (veritable in the small dish)  is the best marriage.

Retrogress to one before for ready

 

Answer

Commentary

In 11 rounds, Kanchan (gut-shot) win rate is only 34% and deal in rate is 15%.

→refference 

You have enough point, and the game is close to end.

In this case, you had better not to call for Riichi waiting bad form and low score.

If you win by  this hand, you got only 2600 pt.

Further more, when the other player win by self draw, you have to pay more 1000pt (Riich fee).

So, The risk/reward is not balanced in case you call for Riichi.

You had better to look to the final form that can win concealed or can win even if you call for pong or chow.

If you discard 7p and retrogress one before for ready,  you can win in concealed when you draw 2m, 3m, 6,m, and 4p.

Even if not so, you can call for chow 2m, 3m, 6m. 

Especially, if you can call for 2m, you can wait by Ryan-men. 

 

Indeed, this hand win by calling for chow 2m, and self-draw 3m.

Look to a good form of one before for ready

 

Answer

Commentary

Look to a good form of one before for ready

At a glance,  it is no risk to discard 2m or 4s fixing Ryan-men.

Indeed, discard 6p lose waiting for 4 tiles of 7p.

And discarding 2m or 4s lose 2tiles of each ＋2 tiles of 9p.

The difference is that  this hand progress.

When you have Ryanmen × 5 parts , We need to get rid of one of them.

If it comes to that way, you should decide 4 Ryanmen first.

How do you do ??

And if you chose  either  Ryanmen,  you have to leave useless tile.

How about this.

you discard 4s, and make perfect one before for ready.

There is no useless tile in this hand.

Takoyaki is one of my favorite food.

Do you know ??

Calculating Expected Value

 

Answer

Calculating Expected Value

Expected value is calculated by score × winning probability.

This hand, discarding 2m is fix "Frat hand"  " All simples" "Triple sequences" but double sided waiting.

Discarding 5m is fix "flat hand" only, but triple sided waiting.

Which is the better option ??  

The winning probability of double sided wait (Ryanmen) is about 70%.

Simplified expected value  is about 70% × 8000 =5600

And that of triple sided wait is about 80%.

Simplified expected value  is about 80% × （1000×1/3（1m)＋2000×2/3（4 7m))=1500

The principle is to focus the score

Basically, it is too difficult to double the winning probability.

So if you fix rising one more the role (Yaku), you should fix the role which make your hand's score 

double.
