In the solution of Fujisawa Hideyuki ( 754), in which the -/-stones have been played, Black cannot further reduce White's top right corner. If Black exchanges and , for example, he has created a potential approach-move liberty at , but he has also lost a direct liberty. Without either an eye, or another potential approach-move liberty, Black has lost a liberty with this exchange. A further exchange - of Black for White - does not change this fact. White cannot play at immediately, but will not connect at either.

After occupying all other Black liberties with - , White plays , and takes Black's group off the board. Black lacks the additional liberty at the top, and is not a real (approach-move) liberty.
