The theory
Opposite-colored bishop endings are the most drawish in chess: because the bishops never contest the same squares, the defender builds a blockade the attacker can never break.
The method. Choose the square in front of the pawn that sits on your bishop's color, occupy it with king or bishop, and hold it. The attacking bishop controls the other color and is powerless against your fortress.
Why one pawn is not enough. To win, the stronger side usually needs two well-separated passed pawns, so the defender cannot cover both colors at once. A single pawn, or two close pawns, is a draw.
In this drill you defend down a pawn. Find the blockade square on your color and refuse to leave it: the tablebase attacker cannot make progress.
