| 1. B × Kt | Q × B. |
If ...B × Kt; Q - B 3 threatens mate, and therefore wins the Q, which is already attacked.
| 2. Kt - B 6 ch | P × Kt | |
| 3. R - Kt 3 ch | K - R 1 | |
| 4. B × P mate. |
Example 15.—A very frequent type of combination is shown in the following position.
Here White is the exchange and a Pawn behind, but he can win quickly thus: 1 B × P ch, K × B. (If 1...K - R 1; 2 Q - K R 5, P - K Kt 3; 3 Q - R 6, and wins.)
2 Q - R 5 ch, K - Kt 1; 3 Kt - Kt 5, and Black cannot stop mate at K R 7 except by sacrificing the Queen by Q - K 5, which would leave White with a Q for a R.
