Non-Symmetric Problem 2 / Solution

Solution: ko  

Dieter: It's ko.

Robert Pauli: Right.

W's failure: dead  

The symmetric W1 is wrong.

Robert Pauli: Indeed.

B's failure #1: life  

Miai for life: B2 is wrong.

B's failure #2: life  

Miai for life: B2 is wrong again.

Notice the importance of the marked stone.

Robert Pauli: Can't remember these ones . . .

Dieter: If the marked stone isn't there, Black can play b for White a, cut and force White to fill his second eye before she can capture the three stones.

Robert Pauli: Yes, and the other line isn't bad either (DGoZ 3/03, problem 5, by the way):

B's failure #2, continued  

As ugly W4 might be, it wins White the capturing race. Bamboo with W4 wouldn't.
