The pin
Step 1 of 6
The white bishop on b5 looks at the knight on c6. Behind the knight, on e8, is the black king. If the knight moved, the king would stand open to the bishop, so by the rules the knight cannot move. This is called a pin.
A pinned piece cannot run away. Watch what happens when a pawn attacks it as well.
