:eng101: I had difficulties during the last game because I'm also very tactile when it comes to chess. Worse, I don't currently own a chess board. When I have had them, however, I've found it helpful to lay out the positions, play potential moves, and then walk to the other side of the board to play with responses to those moves. If you have a chess board, that may be helpful.

:eng101: Let's explain castling!

Castling is a special move that makes the king and a rook both move at the same time. It can only be done under some circumstances, but first let's cover what it does.

There are two forms of castling: kingside and queenside.

In kingside, the king and the rook on the king's side are used.


The king moves two spaces towards the rook.


Then the rook move one space past the king.


Leading to this final position.


Queenside is similar, except the rook on the queen's side is used.


The king moves two spaces towards the rook.


Then the rook moves two spaces past the king.


Leading to this final position. Notice how the king and rook are more towards the center than with kingside castling.



So when can you castle? Well, first, you cannot do so if either the king or the rook being used have moved.

Second, you cannot if there are any pieces between the king and the rook.


Third, the king cannot be in check (though the rook can be in risk of capture).


Fourth, the king cannot move through any space where it would be in check (the rook can do so, though).


Fifth, the king cannot move into check (as always).

:eng101: One more thing! I mentioned that some of the restrictions for castling don't apply to the rook. Let me show you.

If the rook is threatened, you can still castle (unlike being in check)




As well, the rook can travel through threatened spaces when castling (unlike the king)
