Overprotection

A concept first introduced by Nimzowitsch.

"If ten bodyguards look over a diamond, one can take a coffee break"

Overprotection is a very deep concept. If you practice that, your opponent does not get any tactical chances. Tigran V. Petrosian practiced this and credited Nimzovich for it.

@QueenMyPawn why would you EVER castle short as white here... that is ridiculous. I am really questioning your opponents.

Even his contemporaries lampooned weirdo AN in those days. He simply overdid it!

Time to study @Sarg0n . Very interesting response to the French.

Honestly, I think overprotection as a concept is a bit overblown. Watson discussed this (in the Modern Chess Strategy books).

It is also often misused. Nimzovich intended it only in regard to strong points...but many believe themselves to be "overprotecting" weaknesses.

That's a good caveat @MrPushwood . Protecting weaknesses leaves you passive, but protecting strengths can leave the opponent feeling restricted.

@Sarg0n I don't get it. What is this whole overprotection thing for? Why didn't the black king simply escape towards the queenside?

I do not like overprotection, I prefer active play
to lead the game even if I lose, styles I guess
However if whatever reason you need to protect something
more than once, well you can do it.
I think however overprotection its a concept,
I did not a study it and should not be confused
with king safety that is an algebraic defence structure, specially the castling.

@BlindfoldedNewbie Overprotection is meant to stop the opponent's active play. See my above comment.
