Opposite Colored Bishops Chess Puzzles

Opposite colored bishops means each side has a bishop on different color complexes (one bishop controls dark squares, the other controls light squares). A defining feature is that the bishops can never directly challenge each other on the same squares, so pawn structure and square-color weaknesses become the real battleground. In many openings, this arises after exchanges that leave one side with a bishop pair trade and the other with a single bishop, often around the middle game.
