and White wins one of the two Bishops, remains with a Q and a B against a R and B, and should therefore win easily. These two examples show the
danger of advancing the K Kt P one square, after having Castled on that side.
Example 13.
This is another very interesting type of combination. Black has a R for a Kt and should therefore win, unless White is able to obtain some compensation immediately. White, in fact, mates in a few moves thus:
| 1. Kt - B 6 ch | P × Kt |
Forced, otherwise Q X P mates.
| 2. Q - Kt 3 ch | K - R 1 | |
| 3. B × P mate. |
Example 14.—The same type of combination occurs in a more complicated form in the following position.
