Lolli’s Mate is a common checkmate pattern performed by the cooperation between a queen and pawn, typically against a castled king. It’s named after Giambattista Lolli, an Italian chess player from the 18th century.
Lolli’s Mate Example #1

Diagram above: White plays 1.Qg7# The pawn defends the queen. This pattern is fairly common and is known as Lolli’s Mate.
Lolli’s Mate Example #2
In many cases it becomes almost impossible to defend against the Lolli’s checkmate pattern if a similar position appears on the board, particularly if the rook is still next to the castled king. The next example will illustrate the point.

Diagram above: White plays 1.f6, threatening 2.Qxg7# The only way black can block the checkmate is to play 1… g6, but this will then allow white to execute the Lolli’s checkmate pattern.

Diagram above: After 2.Qh6 there is nothing black can do to prevent 3.Qg7# on the next move.
