Error in Opening Name?

Hello everyone,

I've been trying out some of the Chess Mentor lessons here on chess.com and recently completed "Morphy Gambit Introduction" by FM Eric Schiller.

I tried looking up this opening on the game explorer or opening database and can't find it. On the game explorer it calls it the Bishop's Opening: Berlin Defence however that's only after the first couple moves, after move 3 it doesn't provide any names.

Searching "Morphy Gambit" gives you some results, but none are the opening presented in Schiller's lesson.

The opening in Schiller's lesson is: 1.e4 e5 2.Bc4 Nf6 3.Nf3 Nxe4 4.Nc3 Nxc3 5.dxc3 f6.

Anyone know the name of it, or if it even has one?

Thanks!

Up through move 4 I'm showing it as a transposition of the  "Russian Game: Boden-Kierseritsky Gambit Accepted." The the actual move order for that is listed as:

That is from SCID's ECO browser.
