user31998: 
Anyone know the name of this motif? I have seen it several times, but never knew the name. Source Polgar 5334 problems.
Can one classify this as a Legal's trap motif due to the famous Queen sacrifice(Bxd1)?

user31955: The move Nxe5 echoes the famous game by Legal, because if black captures the queen, checkmate is then unavoidable. However, I would classify this motif as a discovered attack(which includes checkmate itself). There is some more useful information here
In the OP, the discovered attack is 1.Nf6+, which is followed by 2.Bxf7#
