There are two endgame spots here.
Are these the same? If not, where is bigger? And, how about the exact value?
I don’t know exactly, precisely saying, there is my definite opinion, but I want to hear other people’s opinion.
I will post my opinion three days later, and link to this page.
I had created these data, and now making more.
Leave a comment about this if you are interested in.
Following shapes are all gote 14 endgame.
I can explain, but think yourself first. It helps to improve imagination power.
It can be sente 4 for black.

If white 5 instead of 4, picnic-ko.
White must go A. Sente seki, thank you!
It is the same.
Real practical situation is below.

Can you invade bottom right corner?
Let’s appreciate that white player uses A and B and invade the corner.
Black player is trying to kill white invader.
It can not be anyting without breaking.
Black 2 move is thank-you-move.
White makes ko! A is ko threat and black player received B.
As this is already a big problem in black camp, you will be noticed. Following procedeur is below.

This black 1 is the way black escapes ladder breaker.
Black 1 and 3 is combination.
White must select A or B.
I was worried where it should be included between “life and death” and “endgame.”
1
2
3 ( very important in practical go)
4
5 ( very important in practical go )
 |
6
7
8 ( important in practical go )
Um.. This shape is more practical.
9 ( essential in practical go )
Black 5 move is very important!
 |
Because white can live instead of seki. about +4 cap.
Be careful of A point. If there is filled, white 4 is impossible because of self-atari.
10 (essential )
11 ( essential and very important )
sente.
gote.

But, be careful of it. If white has lots of ko-treats, white can do this.
today’s pattern tesuji
 |
Today, I prepared something fresh. This pattern is useful at endgame.
First, find this pattern.
Empty point is the key.
This pattern, according to opponent’s response and determine my decision that way, some high-level issue.
If white 2, black can take A or B anyway.
If white 2, the same. Black can take A or B.
First, find the pattern.
Now, we can know where is the key.
If white 2, black chooses move 3.
If this white 2, black can make picnic ko.
Uh… oh My fool English! lol
White 2 makes the same result.
In fact, Korean, then I would write too many contents.
application 02:09 August 11 in Korea, added.
White received move 4.
Black B is the site of A role.
So, black 1 is the key.
Black already lives.
If white 2, black can choose A or B. lol
I am showing that these patterns are practical in real go.
In practice, it is important that you just imagine and apply patterns.
