Trapped pieces (2)

You already know about trapping pieces. Trapping can be done in several ways. These are the most typical means of trapping pieces:

1. Use your pawns or pieces to limit the mobility of the enemy piece. A trapped piece can no longer actively participate in the game.
2. Chase away the enemy piece to a bad square or to a corner of the board, where its mobility is limited.
3. Lure the piece into your own camp and cut off the ways for retreat.

What do you have to do?
First, find the trapped piece in the position. Then, win this piece by attacking it. Capturing a trapped piece is of course the most direct way to exploit it.

In some of the exercises, you have to do a couple of forcing moves before you can win the trapped piece. Have fun!
