Good Bishop vs. Bad Bishop
A bishop's real strength depends entirely on its own pawns — free diagonals make it a monster, while a wall of same-colored pawns can turn it into a spectator.
Key Ideas
- A "bad bishop" is blocked in by its own pawns sitting on the same color square as the bishop.
- A "good bishop" has open diagonals, usually because its own pawns sit on the opposite color.
- Deciding which pawns to place on which color squares is a core opening and middlegame planning decision.
- A common plan against a bad bishop is to trade it off rather than let it sit passively for the whole game.
How It Works
Because a bishop is permanently confined to one color of square, its effectiveness depends heavily on where its own side's pawns are placed: pawns sitting on the same color as the bishop block its diagonals and shrink its scope, while pawns on the opposite color leave it free to roam.
A "bad bishop" hemmed in behind its own pawn chain — the classic example being the French Defense's light-squared bishop behind the e6/d5 pawn chain — can spend an entire game as little more than a glorified pawn itself.
This is why experienced players think carefully about pawn placement relative to their own bishops from the opening onward, and why trading off a bad bishop (even for a seemingly "better" enemy piece) is frequently the correct strategic decision rather than a concession.
