CR step 3. NES v.s NES (2) /baduk/

It's non-eye-space v.s non-eye-space and there are three in-spaces.

I will seperate two sides. White has more out-spaces. Black has less out-spaces.
First, more-out-space-side always shoulders in-spaces minus one.
Why minus one?
You can answer yourself if you have seen "CR step 2". ( hint : I said very important. )
Now, I provide you with convinience of that.
Triangle marks show burdens of black and square marks show that of white.

It is 4 to 3 for white. So, white can play elsewhere.

Second, if the burdens are SAME, more-out-space-side can win, but less-out-space-side can only make draw - it's the best plan.

It is 4 to 4.
white can win. because white has more out-spaces.

White can kill out with A.
But black can only make draw. because black has less out-spaces.

Conclusion : More-out-space-side always shoulders in-spaces minus one. / If the burdens are SAME, more-out-space-side can win, but less-out-space-side can only make draw.

cf. White can go elsewhere maximum ( never die ) the gap of out-spaces plus in-spaces minus one.

CR step 2. non-eye-space v.s non-eye-space (1) /baduk/

There are non-eye-space black and non-eye-space white.
And there is not in-space anywhere.
So, the result is decided by "out-space."
Black has 3 out-spaces, and white as well.
Therefore, the side going first will win.

There are non-eye-space black and non-eye-space white.
And there is one in-space.
Likewise, the result is decided by "out-space."
Because in case of non-eye-space v.s non-eye-space, "only one" in-space owns in common. ( It's very very important. )
Black has 3 out-spaces, and white as well.
Therefore, the side going first will win.

p.s I hope to communicate with visitors more and I will be very happy if you vote your country (nation).
