Push/Fold in Real Hands (2)
Continuing from the previous page:
Example 6
This hand must never be damaten.
The value increase from riichi is enormous, the point situation is not one where you should back off, and there is no useful shape improvement left.
So there is not a single reason to leave it damaten.
I would call even one turn of damaten too soft here.
Answer: cut 
and declare riichi
Example 7
With a two-shanten hand, even a tile that looks "fairly likely to pass" is better left uncut.
In this hand, I think many players would be tempted to touch 7p.
Since the dora is 
,
it is true that from a 468p shape, the opponent is unlikely to discard .
That kind of reasoning is not wrong.
Still, the tile can hit unusual shapes such as a shanpon wait or something like 5568.
You may end up cutting 
later anyway,
but full-folding has one iron rule:
cut the safer tile first.
Answer: cut
Example 8
Being too attached to yaku is almost never profitable.
This hand is one-shanten for junchan, sanshoku, and iipeikou.
But the third 
is already visible on the table,
which means the winning outlook for this hand is now almost gone.
The winning move here is to cut off your own attacking chances cleanly and switch straight into full folding.
Strong players do not overrate yaku in spots like this.
They simply ask, in a calm way:
"How likely is this hand to win now, really?"
Answer: cut
Example 9
This hand has no genbutsu at all.
But that also means there is very little reason to believe a two-shanten hand like this can successfully push through and win.
The basic plan is still to reduce your chance of dealing in as much as possible.
In a spot like this, it is fine to rely on the practical feeling that:
"dropping an honor pair is usually pretty safe."
Even if it turns out to be an abandoning hand against East, there is absolutely nothing to regret.
Answer: cut 
Example 10
This is a miserable one-shanten that is not worth fighting with, so you really have no choice except to cut the genbutsu 
.
It also looks very easy for this hand to get stuck afterward.
If both genbutsu and suji disappear, you will probably have to hang on by cutting 
,
since it can be cut twice and only deals into the 1s-4s side shape.
