Don't play on the point of symmetry

Problem  

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

Failure  

The point of symmetry is not the solution.

Solution  

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

Solution  

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

Example 2

Problem  

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

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

Not recommended  

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

Recommended  

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