how to protect a castled king

I really don't know the best way to protect my castled king. it is held that one shouldn't move any pawn at all, while other believe one should leave an escape route from the 1st/8th rank for the king

If you're castle kingside:
• You should have a knight on f6 or f3.
• You should move your h-pawn to h6 or h3
• Take care about your very weak g-pawn. (Do you know, when queen is on the g-line, and a bishop comes attack the g-pawn from h3, but the g-pawn can't take it because of pin? That's very dangerous.)
• Pay attention to your opponents move. If that move attacks your f, g or h pawn, think a minute.
If you castle queenside:
• You should move your king to b1 or b8
• You should move your a-pawn to a3 or a6.
• You should have a knight on c3 or c6.
• Your b-pawn is very weak. (g-pawn is the same in kingside castle)
• Pay attention to your opponents move. If that move attacks your a, b or c pawn, think a minute.
Both sides:
• When you're attack, pay attention to you're castled king.
• You can never be sure you're king is safe.
Plus informations:
• You can castle kingside if you're f pawn has moved, but only if one of your knights are on c3 or c6.


I hope this helps you.

Thank you very much for this

"the best way to protect my castled king." ++ With a knight on f3/f6.

"one shouldn't move any pawn at all" ++ That is generally correct.

"one should leave an escape route from the 1st/8th rank for the king" ++ Only when you must.

No, @Tygxc, you should move one of your pawns to have an escape square for your king.
And, yes, you forgot about queenside castle. You write only the kingside castle. If you castle queenside, you should have a knight on c3 or c6.

@bobby_max why?

@6

Well you should know, at least you are rated 1050...

A pawn on h6 is a weakness. It is a mark for attacking with g4-g5 or Bxh6, or Nxh6, or Nxg7, or Bc2/Qd3... Only play ...h6 when you must.

Put a bunch of pieces in front of your castle

I hate to defense that's the wrong….
