When is Castling Not Allowed

Hi,

This might be a basic question which is answered already.

What are the situations when a castling is not allowed be it king or queen's side.

This came to my mind as there is a game when I was not at all allowed to castle to queen's side while the opponent's white queen was at f6 and my black pawn at e7 was at e6 and the all the pieces at the 8th square was not there excpet the rooks and the king which was not moved at all.

I initially thought it's a glitch in the program until I analysed it using computer which showed me I can't castle !!!

Request an answer to all the scenarios or at least a link where I can study the same.

Thanks in advance whoever helps me out.

Regards,

David

The Wikipedia article on castling has a concise explanation: http://en.wikipedia.org/w/index.php?title=Castling&oldid=604146415

You can't castle if you have ever moved your King (not even if you moved it back later) or the Rook you want to castle with; or if you are in check, or would be castling across a check or into a check. Enemy attacks on the Rook don't matter... you ARE allowed to castle even if the Rook is under attack.

Thanks forgot about wiki .. good article

Tell me in this situation why castling is not allowed? This is just a sample produced by me not actual game

White cannot castle Q-side because his King would have to pass over a check on d1. K-side castling is allowed... unless the King or Rook has already moved earlier in the game.

sorry, man, but if you dont know when castling is not allowed you probably need to do some serious studying before you even attempt to play a game.

You can move the rook as many times as you want but it has to come back to its original square before you castle. The king is the only piece where the rule applies that you can't castle after already having moved the king.

Are you sure? I was taught that if a rook moved castling would no longer be possible on that side. I've been known to be wrong on things before though.

Ah I didn't knew that. I thought King cannot castle only when he will come directly under attack.

Theory is good but it is the practicals which teaches us, this situation happened in a game i was playing, I didn't knew this rule. Neither king or any rooks ever moved and still Iwas not able to castle Q-side.

That's flat out wrong. See the Wikipedia link I cited earlier, or the FIDE laws of chess (http://www.fide.com/component/handbook/?id=124&view=article), or the description of the rules right here on chess.com (http://www.chess.com/learn-how-to-play-chess#special).

Agreed.

how can someone with as many games as you have and with you rating be this dense?  Or do you use a program to play for you.

When you castle the king makes two moves in the same turn and the rook then 'jumps over' the king. If moving to either of those two squares would put the king in check then you can't castle. 

I remember having trouble with this because when I slid the king over I didn't notice that a square was covered by an opponent's piece.

You are being unnecessarily harsh. Victor Korchnoi, during a game in his 1974 Candidates Match against Anatoly Karpov, had to ask the arbiter if he could castle when his rook was under attack. If an almost 2700 FIDE player isn't sure of the castling rules, then surely a mere 1670 chess.com player can be excused.

Most likely he simply learned the game orally, like many players do, and whoever taught him got it wrong. You could probably play thousands of games without running into a position where this would be an issue, and so it is easy to see how someone could go through a long chess career and never find out they were using the wrong castling rule.

No.  The rule is that if you are targeting the King, or a square the King has to pass through, or the square he ends up on, you cannot castle.

As b1 is none of these, castling is legal.

Can you castle when the piece that is preventing you from castling is pinned?
