captures the black stones.

# Solution (Part 1)

If Black plays elsewhere, at captures .

and are forcing moves to help Black move out a little faster.

( at )

# Solution (Part 2)

For information on at another place, see Failure (Part 2)

# Solution (Part 3)

at a is normally considered to be the mainline solution of this problem.

at b and c are pretty interesting, too.

### Solution (Part 3) Resistance 'a'

at x would be a transposition to the variation in Resistance 'b'

( at )

# Failure (Part 1)

This part is about other than this solution move.

Since after , the black chain has 5 liberties.

The only possible (other than the solution move or silly kikashi) would be at one of the x, or gets captured.

For the other , after , the black chain has 5 liberties.

# Failure (Part 2)

This part is about other than this solution move.

If White wants to keep the black chain's liberties less than 5, White needs to play on nose points like , , and .

This turns into a ladder that doesn't work.

Next Black has x or y.

# Failure (Part 3)

This part is for other than this solution move.

threatens a ladder. After , White needs a move at a, so Black should win the capturing race.
