The larger the number of enemy stones captured within your group, the less likely it is that your surrounding stones can be killed. There is no case where a capture of more than 17 stones fails to provide living eyespace.[2]

Bob Myers: Apparently the creator of this page thinks that nakade means "any clumplike bunch of stones of your opponents that you capture but then after that there are moves he can make inside the newly vacant area that can kill you." Unfortunately, that's just wrong. I don't think there's even any word for that. There's already enough confusion about nakade to avoid compounding it like this.

The best I can come up with is "Largest capture that still can't live", and would like to request that this page be so renamed.

Bill: JohnF, on Nakade example 2 /Discussion, reports Hayashi's definition:

The base meaning is a "move inside". Hayashi does not restrict this to any particular shape except to say that the surrounding group is "continuous". From the examples I have seen, it is safe to say that the shape into which the "inside move" is played is always fully enclosed. It may, however, have defects.

I think that covers this position. It is the defects which allow the nakade inside such a large eye. Besides, take a look at the third example below. Both Hirose Heijiro and JohnF consider that a nakade, it appears.

Bill: In a comment on Nakade Example 2 / Discussion John Fairbairn mentions an example in a magazine covering a 36 point area.

Robert Pauli: Gee, like to see that one :-)

Bill: Me, too. :-)
