What is False Eye Life? (the term is a so-called "rare rule".. was recently heard on rec.games.go). Thanks for any answers.

- Kungfu

I think this must refer (in John Fairbairn's recent thread) to life in a two-headed dragon, as it is called here.

- Charles

It might be a reference to Moonshine Life.

Nodog: Is the following situation "False Eye Life?" It doesn't seem to be the same as a two-headed dragon.

[Diagram]
1.5 + 1.5 = 2 for Black

For this situation, I've come up with a proverb of "1.5 plus 1.5 equals 2." This means that if you have two groups with one eye connected by one or more false eyes, then you have life, just as if you had 2 eyes.

I know that the "false eye" could be filled in here to create one group with two eyes, but this is different because Black actually gets the point in Japanese counting.



Kungfu:

A false eye is a connection. If there is one or more eyes on both sides of that connection, the group would be alive. Because of that I wouldn't consider this false eye life. "What John and Charles said" :)

-Kungfu


Jan: I interpreted the list in John's post as follows: he starts off with some strange ko's (triple, quadruple, mannenko, you name it) and continues with some illegal plays (illegal captures, two moves in a row etc.). The false-eye life item is on the boundary of those two parts.

Couldn't it just mean that a group was declared alive while one of its eyes was false?

Charles You mean a game between two pros in which they both made the mistake of thinking a dead group was alive? I don't think so ...
Jan Yes, but I find it about equally unlikely that a pro moves twice in a row :-) Are two-headed dragons really that uncommon that they are worth a mention?
Charles I know of only two pro games in which they occur.

But what on earth is torazu sanmoku John alludes to at the end of his post??

Ack! I should read the entire thread first! See [ext] http://www.britgo.org/bgj/06012.html for an explanation - it is an old rule three points without capturing.
