Conceal your 5200 hand

 

Answer

②　Concealed

Commentary

 Last article said that the hand only flat hand is always Riichi.

How about all simples without flat hand ??

In this case, Riichi is bad choice.

On the far left column is the average score of winning.

The others are the statistical balance for each round.

There is almost no differences between calling riichi and concealed hand.

One of the reasons is the peculiarity of the score of 5200.

If you call for  Riichi from 5200, the score would not be doubled.

 you would only be paid 1000 points for Riichi fee and 2800 points would be added.

When it comes to round 12, the difference is only 100 points.

Still, even at 500 points, Riichi is still statistically ahead, so I think it's worth considering until round 8. Basically, concealed is the way to go.

Ready hand only Flat hand is always Riichi

 

Answer

①　Riichi

Commentary

Ready hand only Flat hand is always Riichi

This is a Flat-hand-only in the 12th round.

Whether to pay 1000 points riichi fee in order to get  more 1000 points of the hand of 1000 points.

Just remember this.

Flat hand only is always riichi !!

On the far left column is the average score of winning.

The others are the statistical balance for each round.

In the 12th round, even if you keep concealed, in the long run, you will end up in the negative.

Even if you don't win the hand, the effect of letting other players folding is tremendous.

You should also reach at the end of the game to reduce the possibility of your hand dealing in and to increase your chances of getting a no ready hand fine.

Patterns that should be back from ready hand even if it breaks the completed elements

 

Answer

Commentary

Patterns that should be back from  ready hand even if it breaks the completed elements

If you are an advanced player, you don't need an explanation, and most people will discard the 1m.

It is ready hand whether you discard 2m or 4s.

Moreover, drawing 1m,5m, 7m, 3p, 5p, 3s, and 5s gives this hand Flat hand.

And 4m, 8m, 2p, 6p, 2s, and 6s is good form to call Riichi.

Still, we should discard 1m  here.

The reason are that, 

①　Score

②　Whether or not you can call

If you discard 1m, you can back to ready hand by drawing 4m, 8m, 2s, 5s, 3s, 6s.

This can clear  the criteria (6 or more types) for baking from ready hand.

 And, you can call for Riichi by twice or Four times the score ( flat hand, and all simples).

If you draw 4m or 8m, you can get triple sequences.

Next merit is that whether or not you can call.

You don't need to draw 4m, 8m, 2s, 5s, 3s, 6s yourself.

If left side player discard it, you can call for chow for the same amount of points as if you had discarded 2m and 4s.

Acceptance of 6 or more types can back from ready hand.

In addition, if your hand is the above two conditions , you 'should'  back.

Kanchan of 3 tiles left vs Penchan of 4 tiles left

 

Answer

Commentary

Kanchan of 3 tiles left  vs  Penchan of 4 tiles left

Probably many players will drop the Penchan and keep the Kanchan.

The reason for this is that Kanchan can change to Ryanmen.

In reality, however, the possibility of Kanchan changing into Ryanmen is not that high.

The change to Ryanmen requires drawing one of the basic 4 or 5 or 6, and the possibility of drawing the remaining 4 tiles of Penchan is actually much higher.

With 3 7 "not even a single tile in the river", the odds of winning a Penchan are not that low.

If even one tile is visible, the win rate is drastically reduced.

In the case of only one tile of wait, remember that the difference between heaven and hell is whether there is only one in the river or not.

The way to take temporary ready hand

Answer

Commentary

The way to take temporary ready hand

Discard 9p　　　 →wait for Shanpon

Discard 7p or 8p    →wait for Single wait

Discard 1s 　　　 →wait for one before for ready

First, discarding 1s is bad choice.

If you draw 2s or 3s, you can wait 6-9p.

But the possibility of drawing 2s or 3s is only 6% per one rounds.

This is no way to compete.

So which is more advantageous, a single wait or a shannon wait ??

Shannon wait can not change to wait.

But single wait is very flexible.

If you draw 2m, 4m, 6m, 8m, and 1s, you can wait Ryanmen and complete Flat hand.

If you draw 5m, you can wait triple wait, 2-5-8m.

Of curse,  you can wait Dora, if you draw North.

8p is superior to 7p because 8p is safer to 7p.

Criteria of backing to one before for ready

Answer

Commentary

Criteria of backing to one before for ready

If you discard 5m, this hand is ready.

And if you call Riichi, this hand has Mangan ; riichi, All simples, double sequence, and dora, it's not bad.

Statistically, you may call riichi.

But this Kanchan is too difficult to win experimentally.

Many player wants to back to one before for ready.

 When  would you be allowed to retrogress??

One criteria is 

"Back to one before for ready  if there are more than six tiles of valid alternatives"

Why 6??

The probability of drawing the desired tile in one round is approximately 3%  (1/34).

If there are 6 types, that's about 20% per one drawing.

 There's a good chance you'll get one of these tiles within 5 rounds (20×5＝100)

If it takes longer than five rounds, it's better not to wait in most cases.

→Reference past article

In this hand, 1m, 4m, 7m, 4s, 5s, 7s, 8s, is valid to wait Ryanmen.

If you draw Souzu, you can wait triple sided, and look to triple sequences of 4 5 6.

You should back in such a case.
