## Solution

Solution

is necessary, eventually. It can also be at a, or any other move that protects against the cut. captures three stones.

Solution

Black recaptures at and blocks. Next connects at . Black has 25 points of territory, plus one prisoner. White has 16 points of territory, plus 3 prisoners. On the board Black wins by 7 and can thus afford a komi up to 6,5 points.

## Failure

Mistake - Black loses

For Black to connect at leads to a hideous loss, because of a shortage of liberties.

If Black does nothing

If Black passes

If Black does nothing (ii)

he cannot connect at after . If he connects at a instead:

Ko

White takes the ko and has more threats, starting with the cut at a. So White connects the ko and Black wins by 6 points. Black has lost a point.

White response

## The cut

The cut

The cut at here doesn't work. White can't get more liberties than either of the black groups.
