How to Force Checkmate with the Bishop Pair
From Good to Great: Pro-Level Tips
Use the Bishops to Build a Wall
Your bishops should work together on adjacent diagonals to form a "wall" that slowly shrinks the area the enemy king can move in. Don't check the king unnecessarily; focus on taking away squares with each move.
The King Does the Pushing
Your bishops control the long diagonals, but it is your king that must do the close-range work. Use your king aggressively to "push" the enemy king towards one of the corners of the board. The final checkmate can only be delivered in a corner.
A Move That Made History: Prokes Study, 1937
This famous endgame study by L. Prokes is a masterclass in the two bishops technique. It's not about a flashy move, but about precise, patient maneuvering. White must use their king (triangulation) and bishops in perfect harmony to drive the black king into a position where it can be mated. It highlights the importance of not rushing and understanding how the pieces must coordinate to achieve the final goal. The solution involves losing a move with the king to achieve zugzwang.
