{ Capablanca's rule - When the opponent has a bishop, keep your pawns on squares of the same colour as your opponent's bishop.
In the above position, black has two drawing ideas -
1. Fix white's pawn on light squares and maintain a blockade on the dark squares
or
2. Exchange the bishop for both pawns } { [%cal Rf4f5,Ge4e5] }
