Figure 6.2.5.10[Black to move]

Damiano’s mate typically involves a pawn on g6 exerting diagonal pressure against f7 and h7. But a bishop on g6 can do similar work, too, just as a bishop filled the role of Lolli’s f6 pawn (and more) in the last study. The most important point about a bishop’s strength from g6 is its ability to provide cover for the queen on two different squares: h7 and f7. This becomes useful in hunting down a king that tries to wriggle away along the back rank. Thus in the diagram to the left the queen currently has protection from its bishop; Black can move his king to f8, but then White has Qxf7#—again with protection from the bishop.
