I was very nervous at that point in the game, black had very little time left, and there was a crowd (almost 30 people!) around the board, including the late, great, GM Tony Miles.
I knew immediately when I had blown it with dxe, since the crowd dispersed pretty quickly shaking their heads. : /
Nf6+ was probably unsound, and Black's Qd7 moving off the dark squares was a bad mistake. : /
Looking at this game, I get the feeling I was better back then, since I don't understand why I played some of the moves I did. ; )
