King on d1: Kingside
The king on d1 — right in the middle of the first rank, between two rooks. Kingside castling will send him to g1 — three squares towards the corner, under the pawns' protection. I've noticed: when the king is in the centre, he's easier to attack, so you want to castle as soon as you can. Drag the king onto the rook on h1!
Your move — make it on the board
The king is hiding on g1! Now he's at peace — and so am I.
