Another BDG Declined

A BDG declined was played at the Karnevalsopen in Solingen, Germany a couple of weekends ago. I first noticed it in Mark Crowther's TWIC, and was encouraged to find that Black was listed as a reasonably strong player with an Elo of 2286. There was no rating listed for White, so I checked the tournament site and found there had evidently been a transcription error, as Black's rating was actually considerably lower. Still a BDG is a BDG (in this case, a declined BDG):
