Yeah, I inverted the colors of the whole images, just ignore the blue channel. :wink:

I was expecting it to be green. :thinking:

I think you will figure out the answer more easily if you try koans with more stones and on a bigger board.

I don’t 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.

Maybe those will give green koans without clamps.

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.

Does 765 on a smaller board make a difference?: image
Are the 4 white stones of 763 important?: image
