Answers.Text: I'd call the latter the Falkbeer Countergambit. It becomes a Falkbeer with 3...e4 and of course it is still a Falkbeer after the common continuation 4.d3 Nf6 5. dxe4

Answers.Text: @bof I know it's the Falkbeer Countergambit; the Wikipedia link pointed to it. But I think the OP's question was about the name of variations *within* the Falkbeer Countergambit.

Answers.Body: <p>As already said, 3. fxe5 ?? is a terrible blunder after which the computer's evaluation drops from about equal to -5 (in Black's favor).
  The correct reply by Black is to play Qh4+:</p>
  
  <pre>
  <code>
      [FEN "rnbqkbnr/ppp2ppp/8/3pP3/4P3/8/PPPP2PP/RNBQKBNR b KQkq - 0 3"]
  
      3... Qh4+ 4. g3 Qxe4+ 5. Qe2 Qxh1

  </pre>
  
  <p>The correct play is 3. exd5 by White, after which, Black has the choice to play the "true" counter gambit, probably unsound, but tricky:</p>
  
  <pre>
  <code>
      [FEN "rnbqkbnr/ppp2ppp/8/3pp3/4PP2/8/PPPP2PP/RNBQKBNR w KQkq - 0 3"]
  
      3. dxe5 e4 4. d3 Nf6
  
  </code>
  </pre>
  
  <p>And White can claim a small advantage here.
  A safer option for Black is to capture on f4, and you get a balanced game, not really a gambit anymore though !</p>

  `1. e4 e5 2. f4 d5` is known as the **Falkbeer Countergambit**.
  
  However, 3.fxe5?? is not a variation but a blunder. As [Wikipedia](https://en.wikipedia.org/wiki/King's_Gambit,_Falkbeer_Countergambit) explains, you will either lose material after 3...Qh4+, 4.g3 Qxe4+ (due to a fork between the King and the Rook), or expose your King to the black pieces after 3...Qh4+, 4.Ke2 Qxe4+ 5.Kf2 Bc5+.
  
  I am not aware of a name for 1. e4 e5 2. f4 d5 3. exd5 e4 4. d3 Nf6 5. dxe4. Not every opening variation has a name.
