If Black to play, a makes an eye, which gives Black the shared liberties in the corner. Even if White plays at d to stop Black from getting a second eye, Black b kills. Essentially, Black a gives him 3 liberties versus White 1 liberty.
If White to play, White a and then Black d gets one eye. But now White cannot play e as it is self atari. So Black owns the shared liberty at e which can be filled after Black plays atari at b. So it looks like Black wins, again. Have I missed something?
Well, you haven't said what happens if White starts at "d", but I think that's easy for you.
What conclusion do you draw from the fact that Black wins regardless of who plays first?
Sure, White d, Black a for an eye and now Black owns the shared liberty at c.
I figured, but I guess did not state explicitly, Black wins because White cannot prevent him from getting an eye.
I love doing tesuji. I had no trouble doing the problems included with SmartGo at first, but now I am up to those graded 8k, and my success rate at reading the full answers is down to about 1/3 or 1/4. I probably recognize the key first move better than 1/2 the time, though I am often unable to visualize the correct response to some defense, or even completely overlook some defense. But I am nothing if not persistent! Thank you for your feedback.
