C[But this result is good for Black, because Black's marked stone still has some effectiveness.

    C[White has other options, but could even tenuki here, in which case Black's probable continuation in  the top left might be as follows.];

    C[White's marked stone is too close the Black's thickness, but in compensation, Black's marked stone ends up as a funny one space extension.]
