Teaching eyes to beginners discussion

    Keywords: Life & Death

Dieter: The objective of this page has been superseded by the generally accepted page Recognizing an eye). If the authors of this page agree, we can delete it.


Scartol: Look, my goal is to make Go as easy to understand for beginners as possible (especially since so much of it was so puzzling for me as I was coming up). So I think this way of presenting the idea of real vs. false eyes makes the most sense:

[Diagram]
Real eyes  

In general: If black can surround a point with a circle of at least seven stones, he has an eye. (In the middle; fewer stones are needed for the sides and corners.) However..

[Diagram]
False eyes  

If white fills two of the corner spots in the circle, black's eye becomes false. Note that there are exceptions to this rule; once in a while, a shape can survive that appears to contain false eyes (include above examples).


Skelley: I see what you mean and your effort is very much appreciated. I usually use corner problems to illustrate false eyes to beginners. It seems to me that it is easier for them to understand that way.

[Diagram]
False eye  

Something like this.

x is the vital point.

If any of the stones surrounding the eye can be captured then the eye is false.

False eye  

And then this.

x is the vital point.

Bill: I think these are half eyes, not false eyes.
