What is this gambit called? 1.e4 Nf6 2.c4?


How is it developing for white? You've developed your Queen and WAY too early to boot.
I agree with Conquistador, it's the English a pawn down.

It's a bullet / blitz premove gambit.
Some players like 1. e4 e5 2. c4. So not expecting the Alekhine, white premoves c4.
Very powerful the premove gambits.

White has a completely losing game whatever he does.

Well, this position appears in 24 games in the Chessbase "Big 2015" database, as recently as 2012 and with one played as white by a 2600 player, albeit against a player about 500 points lower rated. White won eight of those 22 games, as did black, with the rest draws.
The most popular move is actually g6 which occurs 11 times and Nxe4 only twice!
As for losing, none of the computer engines I checked with including Stockfish 9 gives black more than +0.49 advantage. Not a good opening but hardly losing by force!
But you won't catch me playing it!
Don't care how many times this stupid variation was played or what some computer engines say--it loses.

Thank you, that is it! I knew it had a sweet name "Achilles-Omega gambit!"
The move order is different than what I originally posted but still reaches the same position and still "gambits" or gives up the e-4 pawn with 2...Nxe4.

opening lines in the centre do not see this as losing btw but white must be very dynamic to make the investment pay
has it a name ?probably but i dont know it
i wouldnt follow up with queen c2 d4 looks better as the options for developing improve
perhaps a different move order tho
1 c4 knf6 2 d4 d6 3 e4 when the centre is yours offer the sac
