Fun attacking game against h4

I just had a fun game against an unorthodox opening. 

I've been told that the Blackmar-Diemer Gambit is theoretically unsound. Somebody actually started lecturing me in the chatbox in the middle of a recent game because I played the BDG. And then he lost. 

But I digress. In this game my opponent played an opening that didn't make any sense to me. So I thought I'd take the initiative and play the Blackmar-Diemer Gambit as black if possible. It was very possible and I had an enjoyable win. I'm sure I made several mistakes as my opponent probably did also. 

But it was a fun game and I got to attack in a manner that was pleasing to me throughout the game. 

I share it here with some annotated comments for fun and giggles. 

This is probably a comment for another post, but I found myself wondering why my opponent had a higher rating than me. I don't really care about my rating all that much, but I was never all that impressed with my opponent's play. Of course, I'm sure my opponent's often think the same of my moves. 

Of course, I am trying to learn so I appreciate any comments you care to leave. 

By the way, what is this opening called and what advantages is it supposed to offer white? 

Nice win!

He should have accepted the gambit instead of doing that weird pawn structure. There's a way to turn that trap into bullcrap, and black will be ahead a piece.

eXecute, I think you're talking about the Halosar trap and it is easy enough  to avoid it. 

But I can't help but think there must be more traps waiting to be discovered in these Blackmar-Diemer Gambit declined lines that I keep seeing with overextended pawns protecting each other. 

Yeah, it was very annoying for him to try to protect the pawn or whatever. A move like moving queen next to king, would have lost a bishop but might have saved himself checkmate.

I've found like 2 ways to avoid the Halosar trap. And people don't tend to fall into the trap because it's a bit complicated.

So I don't know if Blackmar-Diemer Gambit is such a sound opening, maybe someone higher rated can answer that.

Even lower rated people love to tell me that it's theoretically unsound. 

I don't particularly care because it's fun and it's good if you enjoy attacking. 

The Blackmar-Diemer Gambit is about more than just one little trap 

Interesting, Gambit King. 

The way I'd learned it was that if white swapped queens, then white is way ahead in development for an early attack. 

By the way, I still wish someone would explain the purpose of opening by pushing a pawn to h4. 

Now, that seems quite theoretically unsound to me.
