Example 17.—Suppose we begin:
| 1. P - K 4 | P - K 4 | |
| 2. Kt - K B 3 |
This is both an attacking and a developing move. Black can now either reply with the identical move or play
| 2. ........ | Kt - Q B 3 |
This developing move at the same time defends the King's Pawn.
| 3. Kt - B 3 | Kt - B 3 |
These moves are of a purely developing nature.
| 4. B - Kt 5 |
It is generally advisable not to bring this Bishop out until one Knight is out, preferably the King's Knight. The Bishop could also have been played to B 4, but it is advisable whenever possible to combine development and attack.
