DIAGRAM 24.

In the case illustrated above it was the Bishop who assisted the
Queen. A Knight could aid in an attack on h7 from either g5 or
f6. More frequently he does so from g5 as usually the square f6
is not accessible to him on account of the Pawn g7 protecting it.
In the majority of cases the Knight goes to g5 from f3, and the
Queen attacks h7 from h5, coming from her original square d1.
Then, if Black cannot protect h7 by a Knight from f6 or by the
Bishop, from f5 for instance, or from g6, the only protection as
a rule is to advance the Pawn to h6. The position of Diagram 25
may serve as an example.
