Post your most painful BDG losses

Ohhh  you had him 

(On another topic: I would have played 5.fxe4 or 5.g4).

Just lost this one   at Blitz
I should have moved my bishop instead of sacking the Queen for the King/Rook fork.

A loss in an engine-assisted game (at another server, of course), in the Lemberger Counter-Gambit, the game ended today:

Bump.

Getting back into chess and just played my first BDG in over 5 years (EDIT: actually more like 18 months, I just checked). It was, erm, interesting.

1. I missed that White has a nice little trap if Black plays ...Bg4 at the wrong time (must remember this one for the future!)

2. I got I think a strong attack going and went up a full rook.

3. My opponent started counterattacking on my queenside. They really had nothing, but I started blundering in time trouble.

4. After the first blunder I was still winning, because of the rook from earlier.

5. After the second blunder I was no longer winning.
