I am new to chess and want to know in what situation can a rook and the king move simultaneously?

I have been playing chess against the computer and I have noticed that at times the rook and the king on the computers side have moved simultaneously. I don't know that much about the game and would like to know in what situations this is possibly. I always thought that it was one piece can move per turn. Any chessperts out there want to help me out with this? I never really paid attention to chess before, but the other day I tried it for the first time and now I am hooked. I do realize playing against the computer is nothing like playing against a real person, but maybe one day I will graduate to the level of being able to play against a real person. Anyway, just curious about this little question, because every time I see it happen I get a little irritated.I am new to chess and want to know in what situation can a rook and the king move simultaneously?
Hi,

In castling the king moves first and the rook second. You may like to visit my web page - link below? Click on 'C' in the dictionary and scroll down to 'CASTLE'. I hope this is helpfulf for you.

the move is called a "castle". it is a very effective move to counter a one sided attack.I am new to chess and want to know in what situation can a rook and the king move simultaneously?
This move is called "castle." That is when the King has not moved and all the other pieces from the row have been moved from between the King and Rook (Bishop and Knight or Queen, Bishop, and Knight). The key is that neither the rook or the King can be moved prior to this move. If either one of the pieces is moved, you can not castle-having the King and Rook move at the same time.
What was previously stated is right. All they have said is right, but I just one to add a final touch. You cannot do a castle if your king will go through a check when performing the move. So lets say you haven't moved the essential pieces, and the knight and bishop (and maybe the Queen) between the king a rook have been removed, then you're ready to make the caste, but if an enemy bishop's diagonal clearly points to somewhere in the path of the castle for example, then you cannot perform the action. Also, the king moves two squares to the side of the castle.I am new to chess and want to know in what situation can a rook and the king move simultaneously?
in check mating.

a rook and a king can move simultaneously when the opponent is loosing..
not possible, newbie
Just remember the king moves first two squares and the rook hops over him to lie beside him. You can castle on either side but castling on the king's side is much more common because it is easier - only two pieces to shift out. Don't be irritated, it's just as much a part of chess as any other rule. Strong players castle in at least 19 games out of 20. It makes the king much safer (as well as getting the rook into play). If you leave the king in the middle he is going to get his beans. Generally castle as early as you can, otherwise you may lose the chance to do so. Another piece of advice - try not to move the pawns in front of your castled king if you can avoid it. The pawns provide protection. If you push them forward he will die horribly.
by the act of castling.you must move your king first to make your intention clear with regard to the actual move
SIMPLIFIED ANSWER:



When the path between the king and a rook is clear, the king may move 2 spaces towards the rook and in the same move the rook moves to the square that the king crossed over last. This is called CASTLING. It can only be done once per game by both sides. There are conditions in which castling is not allowed.



Castling is NOT allowed if:



1. the king is in check

2. either the king or rook has already been moved

3. the king crosses over any squares under enemy attack



...and of course it cannot be done if it puts the king in check.



Good luck! I hope this helps.
