Does this Gambit have Merit?

Here is a game where I played a much higher rated player in the Ruy Lopez. I was able to prevail in this game due to a Knight Pawn Gambit at move 7. At this point in the game we were still in a main line, Does this Gambit have Merit?

The ratings are those of Chessworld and not real life. At move 7 as a friend would say, my opponent is fitting me for a strait-jacket. He wants to seize the Initiative and the Center. I realize at this point I have a chance to grab the Initiative with a Gambit, since he lost a Tempo, setting up his power play.

The best way to refute a Gambit is to accept it and my Opponent does. He didn't have much of a choice though, as declining the Gambit would have led to a Pawn Tsunami on his castled position!

It is possible that my opponent just missed the proper defense, but I must say that I truly enjoyed playing this Game!  ;-)

I would have taken the pawn too! I could not quite get the white rook movement, but..  your gambit is wonderful demonstration of elegant placement of resources!

  Perhaps u r under ranked?!  Congratulations!

Doesn't 14.Bg5 or 14.Bxc6+ intending Bg5 win for white?

Why can't White just play 13. Nbd2 and keep a great position?
