Pin party: skewer
Another lesson about breaking pins. Once again, you are going to take advantage of the fact that pinned pieces are worthless defenders. This time, you will apply a skewer to win material.
You are going to use skewers in two ways:
- You setup a skewer on a quare that is 'guarded' by a pinned piece;
- The skewer creates a simultaneous attack on the king or piece/square AND on a piece/square that is guarded by a pinned piece.
Once you have studied the examples you will understand how this works.
What do you have to do?
Win material by setting up a skewer.
Two black rooks are on the same file, in this case diagonal a2-g8.
The white bishop knows what to do with that! The bishop moves to d5 (Bg2-g5).
But why shouldn't the biship be captured there by the black pawn?
Because that pawn is pinned: when the pawn leaves, the black king is in check.
Black can save one rook, but he loses the other one.
