Play on the Point of Symmetry
Path: GoProverbs   · Prev:   · Next: BewareOfGoingBackToPatchUp
    Keywords: Proverb

In a symmetrical position, play on the point of symmetry.

This Go proverb applies to tactical questions regarding life and death of groups, but also sometimes to more strategic questions regarding invasions/reductions.


[Diagram]
Black to play and live.

In the example, Black can keep the group alive in seki by playing on the point of symmetry as shown in the following diagram.


[Diagram]
Black plays on the point of symmetry.

Of course, sometimes (as in this example) there is more than one point of symmetry - but the proverb will at least reduce your options.


[Diagram]
Black plays on the point of symmetry again.

A possible variation is White playing at W2. Then in this case, Black can apply the same proverb again, by playing at B3. Then a and b are miai, and c and d are also miai, so Black lives with two eyes.


[Diagram]
Still alive.

In this way, Black is still alive.


[Diagram]
Wrong point of symmetry.

However, if Black plays at the wrong point of symmetry at B1 or a, then White W2 to W6 kills the Black group.




Dnerra: Sometimes, it also applies to the opening:

Where else would you like to move?
