Beginner Exercise 54 Discussion
Difficulty: Beginner
Keywords: Problem
The marked space is only good for one eye with White's stone placed as it is. White must prevent Black from making two eyes immediately with a play at 1, so the first move is obvious.
If Black tries to solidify an eye on the bottom, White 3 is double atari and will capture and destroy an eye, leaving black dead. unkx80: Apart from HolIgor's comments below, think also how Black 2 should defend. If you play Black 2 as in your diagram, White 3 can play tenuki; that is, Black 2 actually dies in gote. You mean the diagram beside this text I assume? It seems that if White 3 plays tenuki, Black 4 at 3 makes an eye out of the space at the top, and the four in a row on bottom should make a second eye, with White unable to connect the stranded stone. unkx80: Yes, I mean the diagram beside this text. Hint: See also my comment below.
If Black tries to solidify an eye at the top, white 3 will cut, putting the marked stone in atari. Black cannot connect at a because of damezumari, and will not be able to make an eye on the bottom. HolIgor: If Black 4?
Oops. How about this way? White must be careful not to fill in at move 7, since Black 8 at 7 would capture. Black 4 and 6 can be interchanged. After Black captures 2 stones... unkx80: Actually White 5 can play tenuki.
... White recaptures and Black has no eye at the bottom.
Juha: After Black 2, couldn't White's next move be on any of the three marked points? unkx80: Yes.
