Winning with (or Drawing against) the Bishop
From Good to Great: Pro-Level Tips
Opposite Colors = Attacking Chances (and Draws)
Endgames with opposite-colored bishops are famously drawish because neither bishop can attack the other's pawns if they are on the right squares. However, with other pieces on the board, they are a powerful attacking weapon because one bishop can attack squares the other cannot defend.
Same Colors = Control the Opposite Color
In a same-colored bishop endgame, your goal is to place your pawns on squares of the *opposite* color of your bishop. This makes them immune to attack from the enemy bishop and restricts the enemy bishop's movement.
A Move That Made History: The "Wrong Rook Pawn" Study
This classic position perfectly illustrates the concept of the "wrong-colored bishop". White has a bishop and a pawn on the verge of promoting, which should be a win. However, because the pawn is a rook pawn (on the a-file) and the queening square (a8) is a dark square, the light-squared bishop can never force the black king off it. Black simply shuffles their king between a8 and b7, and it is a dead draw. A crucial piece of endgame knowledge.
The Winning Combination: This is a drawn position.
