Don't play on the point of symmetry

    Keywords: Proverb

Like any other proverb, there are exceptions to the proverb play on the point of symmetry.

The symmetric problems page contains some problems where this proverb does not apply.

Example 1

[Diagram]
Problem  

For a simple example, consider this problem. It is Black to play.

[Diagram]
Failure  

The point of symmetry is not the solution.

[Diagram]
Solution  

The solution is just beside the symmetric point. Of course, being a symmetric position, B1 can also play at a.

[Diagram]
Solution  

If W2 blocks, then B3 is the vital point. After B5, a and b are miai, so White dies in a straight three dead shape.



Example 2

[Diagram]
Problem  

This is a shape problem: how does White protect against the cutting points?

[Diagram]
Not recommended  

The trumpet connection, which is the symmetrical move, is normally not recommended.

Surely this isn't white's best response though, he didn't even try to resist the second peep. ~srn347

[Diagram]
Not recommended  

Because it invites the peeps of B2 and B4, creating the overconcentrated and ugly B2 bomber.

[Diagram]
Recommended  

Any solid connection is recommended, because it leaves Black with at most one peeping point.
