PHILIDOR'S DEFENCE
(towards) Boden's Mate

White develops his Queen to KB3(f3), defends his KB4(f4) pawn and enables long castling.
Black's Q2(d7) Bishop move to KB4(f5) targets QKt8+QB7(b2+c3) but does not prevent 13.0-0-0.

When castling always touch the king first
Under FIDE laws of chess, if a player deliberately touches a rook and then his king, he is not allowed to castle on that side on that move but must still move the rook if legally possible.
