Has anyone seen this line of the King's Gambit Accepted:  
1. e4 e5  2. f4 exf4  3. Nf3 d5  4. exd5 Qxd5  5. Nc3 Qf5  ?

I have not seen it in ECO-2, BCO-2, or MCO-13.  I have asked a
few people about it -- no one else had seen this line! (Hence 
my post)  It is a playable line (for both sides), intended as 
an improvement over 5...Qe6.  I do not have access to any 
databases, unfortunately.  All references/comments are 
appreciated.  Has this occurred in any master or GM-level games?
If no one finds any references to this opening, I'll post some of
my favorite variations.

  1. e4             e5             
  2. f4             exf4    The KGA       
  3. Nf3            d5      This is listing C36 in ECO-2

  4. exd5           ...     4.Nc3 is not strong, and 4.e5 is 
                            not too strong.
     ...            Qxd5    I prefer 4...Nf6 actually.  Also, if
                            4...Bd6 then 5 d4! is very strong. 
                            4...Qxd5 is marked ?! in ECO-2, volume
                            C, page 174.  Nevertheless, I'm
                            suggesting a possible improvement at a
                            later stage that may redeem this move.

  5. Nc3            ...     Obvious and strong.
     ...            Qf5     This is the key move.  This variation 
                            is not in BCO-2, MCO-13, or ECO-2.  
                            ECO-2 gives 5...Qe6  6. Be2  Bd6, etc. 
                            (favors White), and 5...Qh5  6. Be2  Bg4
                            7. d4, etc., also favoring White.

There are many ways to continue from here.  e.g.,

  6. d4             ...     I think this move is strongest.  White
                            is preparing to play Bd3.
     ...            Nf6     A reasonable move.  6...Bd6 seems good,
                            too.  Black will try to keep the pawn
                            for a while.

  7. Bd3            Qe6+    The queen attacks even as it retreats. 
                            White is kept from castling, and Black
                            does not lose any more momentum
                            (although White has a lead in development
                            already).

  8. Qe2            ...     There are alternatives, but this is a
                            safe line.  Neither player wishes to
                            capture, since doing so would help the 
                            opponent's development.
     ...            Bd6     Black's position is solid, and Black is
                            a pawn up.  Only recently did I find a
                            way to get the pawn (or an advantage)
                            back in a few moves.  Before then, I had
                            terrible results on the White side of
                            this variation of the KGA.

I usually play 9. O-O at this point, and Black is safe with 9...O-O.
If White is not very precise, Black will equalize positionally while
maintaining a pawn lead!  This is one of the most dangerous (for 
White) variations of the KGA I've seen (usually, White has many 
options, which is why I have generally declined the King's Gambit 
as Black.).  If I'm in an agressive mood as Black, I'll play the
Dutch.
