Damiano, like Lolli, has his name associated with a couple of related mating ideas. The most important involves a pawn on g6. Like Lolli’s pawn on f6, a pawn on g6 can do valuable work both in supporting an attack by a queen and in cutting off the enemy king’s flight squares. Here White can mate with Qh7; see how the g6 pawn both protects the queen against capture and seals off f7. Indeed, the pawn’s pressure against h7 and f7 leaves the king trapped on the back rank just as it would be if there were Black pawns on those squares.
