Don't provoke damaging plays on the second line

Black has a poor result ...  

This is from the Bermuda triangle page. black+circle is weak - Black should now consider adding a stone at a, to play lightly here.

Is there any way Black can make this position worse?

... which can be worse  

B1 is a bad idea. Now Black's territory on the side, his only gain here, is under threat. B1 is a classic heavy move, since now black+circle cannot readily be sacrificed. It is also in a poor direction since Black cannot hope to close off the edge at both p and q. This can also be looked at as a variation of Squeezing out the Toothpaste.

This type of mistake seems to be very common.

Black 1 provokes an unwelcome development  

This is from a nine-stone game, Black being a beginner. B1 is a related kind of mistake. Even though Black defends everything up to B9, W10 is a chance to attack.

Instead of B1, Black a is good.

Ironically, plays on the second line can be bad also. Nothing is ever clear cut :) Please look at Don't descend, connect
