Ambiguous Ko
Difficulty: Expert Keywords: Ko
Bill Spight: Some years ago I coined the term, sente ko, which seems to be catching on. But looking at this classic example, I realize that it is actually ambiguous, as in ambiguous position.
If White takes the ko she raises the local temperature from 1/3 to 7/9 by threatening to take again. If Black replies at
the temperature drops back down to 1/3. That means that this position is ambiguous, having both sente and gote properties.
