[Mahjong] Calling tiles is not about 'speed.' It is a technique to 'control the table.'
Previously, I wrote an article titled 'Calling Tiles: The Most Difficult Theme in Mahjong Research.'
Research on pushing and folding has progressed. However, there is still almost no systematized theory for calling tiles.
While reconsidering the reason for this, I realized one thing.
Calling tiles is not simply a technique to speed up your hand. It is a technique that
changes the entire round.
What you gain and what you lose by calling tiles
When you call a tile, your shanten count decreases. A flush hand accelerates. If it's a yakuhai, the yaku is also confirmed. Everyone understands this much.
However, there is also much that is lost in exchange.
You can no longer declare riichi
You lose closed-hand yaku
The flexibility of your hand decreases
It becomes harder to change your strategy later
Furthermore, you end up revealing information about your hand to your opponents.
At first glance, it seems like nothing but disadvantages. However, this is the profound part of calling tiles.
Is revealing information really a disadvantage?
For example, you pon a dora. Or you blatantly show a half-flush. What will your opponents do then?
They will hold onto dangerous tiles, change their pushing and folding, and may even dismantle their own hands.
In other words, in exchange for revealing your own information, you are
stripping your opponents of their freedom.
Revealing information is not just about information loss. It is also pressure exerted through information.
The pinnacle of calling tiles: Big Three Dragons
The yaku where this nature appears most extremely is the Big Three Dragons. You pon the White Dragon. You pon the Green Dragon. At this point, if the Red Dragon has not been seen at all, there is no one who wouldn't think something of it. 'I absolutely cannot discard the Red Dragon.' Everyone thinks that.
Even if you don't have a Chun in your hand, you start thinking,
'What should I do if I draw it later?'
As a result, even with a hand that you would normally declare Riichi on immediately, you might hesitate to do so
for the reason that 'I won't be able to stop if I draw a Chun after declaring Riichi.'
In other words, Daisangen
restricts not only your current decisions but your future ones as well.
This is terrifying.
In three-player Mahjong, it ends in a straight line
In three-player Mahjong, it becomes even more extreme. Because there are fewer types of tiles, a Haku Pon or Hatsu Pon happens early in the round.
And then—
I have no choice but to discard this before the opponent completes their set → 🀄️ → Ron.
Such a straightforward development is not rare. I myself have made this mistake before.
'Wait, it's a Ron?'
By the moment you think that, it is already too late. The atmosphere of the entire round had changed the moment the second call was made.
Pao, another kind of fear
Moreover, Daisangen has Pao.
In other words, even the basic principle of Mahjong that 'you are safe if you don't deal into someone's hand' is broken.
The moment you let someone call the third dragon tile, the possibility of bearing responsibility arises even if you didn't deal into their hand.
This is a unique psychological pressure not found in other hands. That is why the dragon tiles become heavier the closer they get to being the last one.
What is calling tiles?
Thinking this far, I arrived at one conclusion.
Calling tiles is,
An action that sacrifices your own freedom to gain control over the situation
That is what it is.
It is not just about speed. It is not just about hand value. It is not just about information.
From the moment you call, your opponents begin to change their hands, their approach to pushing or folding, and even their decisions on whether to declare riichi.
In other words, calling is
not a technique to change your own hand, but a technique to rewrite your opponent's decision-making.
That is why it is difficult to theorize.
However, that is precisely why it is interesting.
Calling is not merely a 'technique for hand patterns' in Mahjong.
It is the most advanced strategy for rewriting the rules of the entire round.
