19.牵制 pin
A pin is a move that not allow an opponent piece from moving, because if so would expose a more valuable piece behind it. Only bishops, rooks,and queens can effect a pin.
For example:
White g5 bishop is a relative pin.
White b5 bishop is now an absolute pin.
绝对牵制：absolute pin 相对牵制：relative pin
If behind the pinned piece, there is the king, the pin is called: absoluted. If non-king, called relative pin.
20.串击 skewer
A skewer is a move which attacks two pieces in a line, similar to a pin, except that the enemy piece of greater value is in front of the piece of lesser value. After the more valuable piece moves away, the lesser piece can be captured. Like pins, only queens, rooks, and bishops can perform the skewer, and skewer attacks can be either absolute (the more valuable piece in front is the king, in check) or relative (the piece in front is a non-king piece).
