# Xuanxuan Qijing Problem 46 / Solution

Attempt - failure

is the most plausible move, but is the tesuji for w and white can make two eyes at a.
So b should find a way to prevent two eyes at a by sente.

Main line - success

Of course is the next candidate. If w responds at or a, will work this time.

So w will resist at , and won't work this time.

Variation - success

For w at , is the right answer.

Attempt - failure

Resistance

unkx80: I seem to recall reading somewhere that is the best resistance, and as a result, the best Black can do is to capture the stones and let White live.

Continuation, strongest?

hhw: Looks like still kills?

Continuation, variation

The Original Problem

shevious: The number 8 in the title means that number of white stones were eight.
Go Seigen said that "the original is incomplete, so Utaro added three stones."

w alive

The flaw occurs in hhw's variation. Unlike the above variation, white is alive in the original problem.

unkx80: Thanks shevious. I posted that variation in a hurry without verification, and now I am caught with my pants down.
shevious: Your recalling was almost correct and quite helpful. I didn't realize the flaw of the original shape until you and hhw commented about the variations.
