Same-Colored Bishop Endgames
Unlike their opposite-colour cousins, same-coloured bishop endgames are quite decisive, extra material usually wins because the bishops operate on the same squares and can't be "passed" like opposite-colour ones. But precise technique is still required.
Key principles
- Fix opponent's pawns on the bishop's colour. This creates a "bad bishop" for the opponent, their bishop is blocked by their own pawns.
- Keep your own pawns on the opposite colour. This gives your bishop freedom.
- Activate the king. Centralise and use the king aggressively.
- Create a passed pawn. With same-colour bishops, a passed pawn is very dangerous.
Winning technique
- Step 1: Fix the opponent's pawn weaknesses.
- Step 2: Improve your king position.
- Step 3: Create a passed pawn (or improve an existing one).
- Step 4: Use the bishop to support the pawn's advance while the king escorts it. The key advantage over opposite-colour bishops: your bishop directly contests the opponent's bishop, so the defender can't simply blockade with their bishop.
Defending technique
- Keep pawns flexible. Don't fix them on the wrong colour.
- Maintain your "good" bishop.
- Set up a fortress if behind in material.
- Create counterplay. Even when defending, look for active moves, passed pawns, threats, and king activity.
Practice
Set up positions with same-colour bishops and 3-4 pawns each side. Practice converting small advantages on the analysis board. See also: 50 Endgame Rules.
