This is a deadly trap where white sacrifices his queen and gives checkmate with his knight supported by his other knight and light square bishop in only 7 moves.

 

Analyzing moves:

At first white plays pawn to e4 square (e4) which is known by “King’s Pawn Opening”. As response black also moves his king’s pawn to e5 square (e5). This is a very common response of black against e4. Then white moves his knight to f3 square (Nf3) attacking black’s e5 pawn. After Nf3 black defends his pawn by moving his knight to c6 square (Nc6). This is a common variation of king’s pawn opening. Then white moves his light square bishop to c4 (Bc4) attacking the weak f7 pawn and the game turns to “Italian Game”. As response black moves pawn to d6 (d6) opening c8-h3 file for his light square bishop. Then white moves his other knight to c3 square (Nc3). After that black moves his light square bishop to g4 (Bg4) pinning the knight. Now white plays the deadly move knight captures e4. Then if black stays inattentive and makes a blunder by capturing white’s queen (Bxd1), then he is gone. Because, after Bxd1 white plays the magical move (Bxf7+). In this position white gives check with his bishop supported by e5 knight. Then black has only move for king (Ke7). After that white play the last move knight to d5 (Nd5#) and it’s a checkmate. This is called the "Legal Trap".

How Black can save from this trap:

As shown on the 2nd position after white plays knight to e5 (Nxe5) black will not capture the queen but the knight on e5 with the c6 knight (Nxe5). Black can't capture the knight with the d6 pawn because if black captures with pawn the white can easily capture the hanging bishop on g4. That's why black captures the hanging knight with his knight for defending the bishop. And in the next move black's bishop can capture white's queen if white not move his pawn to protect his queen. And this will be a better position for black against white in this position.
