Vital to keep the castle well fortified

Therefore it is important at all times to see that the castle is well fortified and the pawns around are not moved indiscriminately.

In the game below, the players castle on opposite sides and play is centred around the King side where Black has castled. Black advances his King side pawns way too much and this allows White to infiltrate his territory with a splendid rook sacrifice. Thereafter Black has no defence and his King is cornered and dragged into a check-mating net.

12. ..Ndc5 13.0–0–0
White has castled on the queenside and things should be interesting now. White has also pushed his Kingside pawns and it would be interesting to see whose attack gets in first. If 13.Bc2 Nb414.0–0–0 f5 15.gxf5 gxf5 16.Nge2

Black is also interested on the King side and immediately advances his King side pawn also. However it is difficult to understand why he wants to do this as it will expose his King
