The b6-bishop is imprisoned for ever in the
black camp and can sacrifice itself for a pawn at
best. White cannot force the bishop's release,
since Black has available some easy waiting
moves with the b4-bishop.
The following marvellous composition by
the then 7-year-old Smyslov gives an impressive
illustration of a rook being shut out of play:

There seem to be two ways to set up
a fortress. Which is the right one?
02) Pieces Shut Out of Play

In the next position White even succeeds in
simultaneously shutting out of play the enemy
queen and knight:
