The best DDG game I have seen for a long time is Tart – Foster, 2004.
The game includes the "Sacrifice of the Season". The amazing move 14.Ng5!! reminds me of my game Heikkinen - Bongiovanni, corr. 1999, which ended in the same move.
Peter Tart sent me some of his DDG games already ten years ago. He wrote that he used to have nothing exciting/shocking/fun to play against the French, but once he discovered the DDG, the fun started.
I know the feeling he once wrote about: "The look on Black's face when you play c4 is priceless."
