Yup, this is correct (assuming magenta means red and cyan means green).
Yeah, I inverted the colors of the whole images, just ignore the blue channel.
Red!
I was expecting it to be green.
I think you will figure out the answer more easily if you try koans with more stones and on a bigger board.
I donβt know, bigger boards mean more possibilities.
Both green
- Koans are valid go positions on any rectangular board
- You can post koans or rule guesses; in the case of a wrong rule guess I will provide one or more counterexamples.
Green
Red
Maybe those will give green koans without clamps.
Both red
I have a slightly ridiculous rule guess, but it took a long time to find one at all, so here we go:
There is a black chain with exactly two liberties. Neither of those liberties can be on the second line.
Counter examples:
Does 765 on a smaller board make a difference?:
Are the 4 white stones of 763 important?:
Both red
Is there any red 5x5 koan that satisfies this rule?
Yup:
I suggest adding more stones!
Let me play with the number of stones and liberties of koan 763.
