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.
