Black's last move, the blunder 16 ... 0-0??, allows White to win a whole piece with the <DOUBLE ATTACK> 17 ♕c2!, threatening both 18 ♕xh7# and 18 ♕x♘ winning a piece.

Black failed to see the danger signs in the position. Before 16 ... 0-0??, he already had one weakness in the loose c6-knigght, attacked by the White c1-rook and defended only by the Black b7-queen. After 16 ... 0-0??, the presence of a White knight on g5 attacking h7 and the absence of a Black f6-knight defending h7 meant that the h7-square was now a loose potential mating focal point.

So 16 ... 0-0?? created two weaknesses for Black, the loose c6-knight and the loose h7-mating focal point. White zeroed in on these weaknesses in the Black position with 17 ♕c2!, attacking them both at once. Black cannot meet the mate threat 18 ♕xh7# -and- save his c6-knight, so he resigned.

A beginner's textbook example of a double attack with a mate threat.

Jun-23-06  notyetagm: 16 ... 0-0?? is a great example of the problem of natural moves.

Black wanted to get his king out of the center and so he played 16 ... 0-0??. Usually castling is a good idea but in this -particular- position it is a game losing blunder, losing to the <DOUBLE ATTACK> 17 ♕c2!.
