Unique lines can be good if you drill them and play them very precisely.
But I think you must simultaneously question whether the positional compromises made in the process will leave you with just a worse position once your prep wears off. Because that's also inevitable.
In this case - there's not really a direct payoff, like sharp continuation where black can easily misplay it. Whites pawns are overextended and easy to undermine. It's nice to chase around / grab the bishop when the diagonal is open, but e5 has closed it. Black doesn't have major weaknesses justifying a gambit. I don't think blacks moves are very hard to find either... objectively speaking leela thinks this line is around . Typically Owens is about +. So you've given up about .55 worth of leela credit in order to play a novelty. I think you can find better novelties in Owens that don't make such major concessions... so I must reject your request to name this opening. I'm sorry but it isn't good so it can't be given a name.
You make a fair point, there is no direct continuation outside of threatening the bishop. The only real advantage comes from black being unfamiliar with the theory, but as with any other opening. However, all I ask is why the Smith Gambit (1. e4 b6 2. d4 Bb7 3. Nf3 Bxe4)--an objectively worse variation (-0.6) of the exact same Owen's Defense opening, according to the engine--is more deserving of a name than mine (-0.3)? If anything, it seems like I created an improved Smith Gambit.
Hello, chess world. Happy Valentine's Day, and happy birthday to my friend Hollye if she's reading this for some reason. Naturally, I spent today creating variations for an opening idea I thought of a couple months ago. It is a gambit I discovered in the established Owen's Defense opening, with only 1 recorded game in the Chess.com database. If my idea does end up becoming an official opening, I would like to claim it as my own and call it the "Henderson Gambit." Below is the opening itself, my 3 variation ideas, and the 1 master game I referred to earlier.
