How much does it gain?

Bill: How much does W1 - W5 gain? At the end Black has 1/3 point for the stone in ko (W3). (Black will have to protect against the cut at a.)

Wrong reply

Bill: Note that Black cannot reply at B2, because W3 threatens Black's group on the left. (See Endgame Problem 31.)

[Diagram]

Black plays first

Bill: If Black plays first he gets 2 points (circle). (He will still have to protect a.)

The original count in the 2x6 region is 1 1/6 point for Black. Each player can gain 5/6 point in gote.

Since there are plays on the board that gain 1 point, W1 - W5 is a small technical error. It does not change the result with otherwise correct play.
