Endgame : Checkmate with knight pair
| Two Knights | |
| Checkmate with a king and two knights is one of the rare possibilities in the game of chess. Sometimes checkmate is possible with two knights against one pawn as the pawn removes the stalemate defense. Sometimes two knights and a king can force a checkmate against a pawn and the king. The tactics is to block the opponent's pawn with the knight and push the king to the stalemate position. The knight however plays the checkmate. |

Endgame : Checkmate with bishop and knight
| Bishop & Knight: | ||
| In this case checkmate is a difficult possibility. The two pieces cannot form a linear barrier to the opponent's king and thus the checkmate only occurs in the corner controlled by the bishop. We get two checkmate positions with these two pieces. The first position is a checkmate by the bishop, the king being in the corner. The second position is created by the knight, the king being in a side square next to the corner. The bishop and king moving on the side, the checkmate can occur at the end of 33 moves from the starting position. |

Endgame : Checkmate with bishop pair
Checkmate with bishop pair
There can be two checkmate positions with the two bishops on board that can occur at any corner of the board. There can be a checkmate in the corner. The second checkmate can occur at the side square, just next to the corner square. With the bishops moving freely on the side, the checkmate can occur in nineteen moves. Two bishops can result in a checkmate with the help of two kings. The bishops are the most useful when they are at the center of the board. The king has to be used frequently with the bishops.
1. Ke2 Ke4 (Black tries to keep his king near the center)
2. Be3 Ke5 (forcing the king back, which is done often)
3. Kd3 Kd5
4. Bd4 Ke6
5. Ke4 Kd6 (Black tries a different approach to stay near the center)
6. Bc4 (White has a fine position. The bishops are centralized and the king is active.)
6... Kc6 (Black avoids going toward the side)
7. Ke5 Kd7 (Black is trying to avoid the a8 corner)
8. Bd5 (keeping the black king off c6)
8... Kc7
9. Bc5 Kd7
10. Bd6! (an important move that forces the king to the edge of the board)
10... Ke8 (Black is still avoiding the corner)
11. Ke6 (now the black king cannot get off the edge of the board)
11... Kd8
12. Bc6 (forcing the king toward the corner)
12... Kc8 (Black's king is confined to c8 and d8. The white king must cover a7 and b7)
13. Kd5 (13. Ke7? is stalemate)
13...Kd8
14. Kc5 Kc8
15. Kb6 Kd8 (Now White must allow the king to move into the corner)
16. Bc5 Kc8
17. Be7! (an important move that forces the king toward the corner)
17... Kb8
18. Bd7! (the same principle as the previous move)
18... Ka8
19. Bd8 (White must make a move that gives up a tempo. This move is such a move, along with Bc5, Bf8, Be6, or Ka6.)
19... Kb8
20. Bc7+ Ka8
21. Bc6#
