A deceptive 7-move trap in the Italian Game where Black bait-sacrifices the e5-pawn to trigger a queen raid and smothered Nf3# checkmate.

The Blackburne Shilling Gambit is an offbeat response to the Italian Game (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4) that aims to bait White into playing 4.Nxe5?, leading to a forced checkmate or massive material loss for White.
It is named after British Grandmaster Joseph Henry Blackburne (1841–1924), who famously played this trap in London coffeehouses to win the standard wager of one shilling per game from unsuspecting amateurs.
After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Nxe5 Qg5 5.Nxf7 Qxg2 6.Rf1 Qxe4+ 7.Be2, Black plays 7...Nf3#. Because White's bishop on e2 is pinned to the king by the black queen on e4, it cannot capture the knight, resulting in checkmate.
White should simply trade knights with 4.Nxd4! exd4 5.O-O (or 5.c3). Black has moved the same piece twice and White holds an easy developmental advantage with zero danger.
