Hi Robin,

My previous description of how you castle was nearly but not quite
right. As soon as I placed the pieces on the board I realized
there is a simpler way to explain it.

May I try again?

1. Move your King two squares in the direction in which you wish
to castle
2. Place your Rook adjacent to the King, inside (closer to the center
of the board) and on the same rank.

This is shown very clearly on the web site below.
