This opening is called vienna game.
What is this opening called?
If you play the Vienna like that you have to be aware of Nxe4.

It's a pretty popular setup that can be reached via various openings (bishop game, vienna game, king gambit declined...). The main idea is to delay Nf3 so that f4 can be played at the right moment.
Since it can be reached by trasposition in various ways is does not have a proper name, you can call it vienna, bishop game or king gambit according to your own preference.
However , in chess literature it's most ofter referred to as a king gambit declined line, possibly because it was the commonest move order when the line was first developed. Nowadays i suppose it's most commonlty reached via a bishop opening move order, to avoid the KGA lines.
Technically whatever the move order the position has transposed to a line of the Vienna Game. It could have been a Bishop's Opening yes, and maybe that's the most common move order to reach it, but opening manuals do have this position in them and Vienna is the propper name as far as I know. If White now plays f4 it might transpose to some kind of the King's Gambit. It can't transpose to mainline King's Gambit Declined because Black doesn't have Bc5,... but it may transpose to one of Black's other ways to decline the King's Gambit after f4.

The pawn is on f2.

The pawn is on f2.
Of course. But it will usually go to f4 (most likely on the very next move) and then it's a straight trasposition to the king gambit. Of course other moves are playable, but f4 is overwhelmingly the main idea in such lines.
(I wasn't referring to the specific diagram position anyway, since the opener asked about the setup in general. The bishop will usually be at Bc5, as you certainly know).
Hey all!
Seeing as I am not a gold or premium member (yet). I would like to ask you what this opening is called (for white). I've recently started playing it, with some very good results.
Just ignore black's position, I just wanted to show you what the opening (for white) is like. Thanks all for taking time to give feedback! :D
