White has 19 legal first moves, fewer than the twenty of the standard array, because the knights reach a different number of squares from where they stand.

Castling short, the king goes from f1 to g1 and the rook goes from g1 to f1.

Castling long, the king goes from f1 to c1 and the rook goes from e1 to d1.

The pawn on h2 starts with no defender at all.
