The Blackburne Shilling Trap , also known as Blackburne Shilling Gambit is one of the more famous chess traps. It is derived from an offshoot of the Italian Game.
Wilhelm Steinitz made the first known mention of this line, noting it in 1895 in the Addenda to his Modern Chess Instructor, Part II. Legend says that the famous English master Joseph Henry Blackburne played this trap against amatuers in games for money, thus the name. The trap mainly relies on the hope that your opponent would get greedy and pinch pawns.
If white falls for the trap, black will immediately bring his queen to g5 and attack not only the knight on e5 but also the g2 pawn, and a now exposed white king.
