user13185: This is a common tactic in various openings. It goes like this:

A bishop pins your knight to your queen
You sacrifice your bishop with check to attract the king forward
You give a check with your "pinned" knight to win the bishop that pinned you

Here is an example:
[FEN "rn1qkb1r/pp3ppp/2p2n2/4p3/2BPP1b1/5N2/PPP3PP/RNBQK2R w KQkq - 4 7"]

7. Bxf7+! Kxf7 8. Nxe5+ Kg8 9. Nxg4

Does this tactic have a name?

user21817: Yes; this is called attraction.  In this position, the White bishop attracts the Black king to f7 in order for the f3 knight to give check on e5, forking the king and bishop.  This combination wins White two pawns.
