Counting question
  • ypercube at 2018-08-18

    Is this count correct? I’m asking specifically about the black E18-E19-F18 group and the surrounding white group?

    Is the black group dead? is the white group dead?

    Or (as I think) are both live?

    It doesn’t make a difference in the result of the game (Black wins either way) but it might have made if the diff was smaller.

    I think it is seki (i.e. both alive and your assessment correct).

    I agree with both of you.

  • GoNut at 2018-08-19

    It’s a seki, so the 3 empty points inside don’t count.

  • ypercube at 2018-08-20

    Thnx all.

  • Sighris at 2018-08-23

    I agree both are alive thus seki; the invasion you (Black / YperCube) made stopped White from getting two eyes, and the invasion itself has no eyes, and the two groups have 3 common liberties which can not be filled in by either player... Note however if White were to make a bad move and fill in the top liberty Black could play atari on White (and self atari) {by playing down, making T – don’t make bent 4!)} and after White captured the 4 Black (T shaped) stones Black could play in again for the kill.
