moves to the answers for the next problem.

Solution 1a

Solution 1b

Solution 1c

In solution 1b, if white 6' at 7, black 7' at 6.

In solution 1c, Black then captures either 1 or 4 stones, saving his group.
Not in BGJ: If white 6' extends at A, black B is fast enough to capture the 4 stones directly.

Failure 1d BGJ had the coordinates shifted up by one row, an impossible series of moves.

White 6 kills.

Solution 2a

White cannot play A without first protecting at B which permits Black to connect at A.

Solution 2b

Black 5 captures the white stones.

Solution 2c

Black 5 kills.

Failure 2d

This black 1 is wrong, but so is white 2. After black 3, black is able to connect his stones out.

Failure 2e

White 2 refutes black 1, preventing black connecting to the outside. And as the next diagram shows, black does not have the option of living in the corner.

Failure 2f

Black 3 cuts white off from the outside, but white 4 lives.

Solution 3a

White wins. (For Black cannot play A or B immediately, needing 3 moves.)

Failure 3b

Black 4 kills.

Failure 3c

Failure 3d

After failures 3c and 3d, black either escapes or kills the corner first.

Solution 4a

Black 5 kills.

Solution 4b

If white 8 at , black captures.

Failure 4c

Failure 4d

And black dies first.
