Capturing the defender 消除保护子

This is often called removing defender, but to avoid overlap with the distraction motif (where the defender is removed by distracting it away rather than taking it), the more specific, "Capturing Defender" is used instead.

It’s white turn, you can find the black knight on c6 is defending the black queen. If white captures the Queen with his d1 queen first, the black knight can capture the queen in return. That is an equal exchange. Is there a better move?

1. Bxc6 ! Good move! Because of checking , black have to move his king or capture the bishop or move some piece to block the checking, anyway he has to spend one move to solve the problem.  then, white can capture the center queen.

Sample 1:  Black move first

1... Rxc4  
Black sacrifices the rook in order to remove the defending pawn

2. Rxc4 
white retakes

2... Nb5# 
and with the defender gone, black now mates 0-1

Sample 2:  White move first

1. Rxe8 !

The key idea of this tactical motif: White looks to "remove" the Knight on e8 from its protection of the g7-pawn 

1... Rxe8 2. Qxg7#
