Probably my best blitz game so far. (Blackmar-Diemer: Ryder Gambit)

Sure it's not a master piece, yet I got very happy to achieve a victory like that.

Good game; you won't be rated 1177 for long if you can play consistently like that.

Another good game played by me with the Blackmar-Diemer: Ryder Gambit 

If you play stupid openings like the Blackmar-Diemer gambit, you can expect to be 1200 for life... Just throwing that out there. A famous quote I read is "Nobody who plays good chess plays the Blackmar-Diemer Gambit, and nobody plays good chess ever will."

@ Clunney: that's one opinion, but recently, the chess.com coach NM Dan Heisman said in one of his lectures that he used to play sometimes this gambit. If titled players play gambits, then they can't be so bad... and they are fun too!

there is a difference between BDG and stuff like the QG (not really a gambit) Evan's Gambit, King's Gambit, heck even the Halloween Gambit

The Blackmar-Diemer is reserved for a special class of players. 1300-1600 coffeehouse players who never improve their chess. I am happy to say I am not one of those players.

Chess.com has on his database 92 games of the BDG:R and in chesstempo.com data base I could find some 150 games of all BDG played by 2200+ players.

NM Dan Heisman's statement about the BDG can be found here http://livestre.am/4I9TE at 14 minutes 40 seconds.

I don't care what NM Dan Heisman says about it. The Blackmar-Diemer has a terrible reputation, and for good reason: it hangs a pawn for no compensation (and the Ryder is outright losing for White, since after 1. e4 d5 2. d4 ed4 3. Nc3 Nf6 4. f3 ef3 5. Qf3 Qd4 6. Be3 Qg4 7. Qf2 e5 White is totally busted). If you want to play the Diemer, that's perfectly fine, and droves of 1300-1600 players also love the thing, but the BDG is not for people who want to play good chess/actually get better. It's for mindless club players who insist on throwing away material every game, and unsurprisingly find themselves permanently stuck in the C class and wondering why they never get better. I wouldn't wish that fate on anyone.

@Clunney: these gambits are very good especially at blitz and bullet games so I really can't understand why you say that the BDG is for mindless 1300-1600 players when all over the world there are 2000+ players playing it. If you don't like this gambit that's fine, but there are people who do, because is very tactical and dinamic. For instance, I don't like the King's gambit and I don't call them mindless... I'm not an expert in the english language but it seems to me a strong word.

Playing it as a surprise factor is fine, and against the unprepared or weak, the BDG can be a fearsome weapon.  But you would be better off learning how to play chess the right way, which is with good, forceful positional chess (which 1300-1600 club players have no idea how to play and will quickly find themselves crushed), rather than barbaric bloodthirsty gambits.  But that's just my opinion.  When I first started playing chess, I played all the stupid tactical stuff, the Dragon, every white gambit I could find, to put it bluntly, if I could hang a pawn in the opening, by God I would!  But I really only got better at chess after switching to serious openings, since there is actually a lot to learn about things other than Kingside attacks in rich openings like the Queen's Gambit or the French, whereas playing the Diemer over and over again (where you're down material and playing for a Kingside attack in every position) really doesn't teach you anything except tactics (which are important, but if you don't know where to put your pieces or what squares to attack, then all the tactics in the world won't help you.).  Anyway, good luck.
