I was just looking up something in a particular opening the other day, and I found the archives of the Gambit Cartel column at chesscafe.com, and it inspired me. These openings look fun!

I do need to get better at tactics and attacking, and giving away a pawn in the opening to get my pieces out faster seems like a way to dive into the "learn to attack or die trying" method.
I had already switched to trying the Vienna Gambit (1. e4 e5 2. Nc3 Nf6 3. f4) as my primary weapon as white. I've been looking for lines that allow me to pick the direction of the opening against the Sicilian, and that column has me thinking of trying the Smith-Morra Gambit, which is one of the few Sicilian major lines I've never really looked at. I've also been looking for a plan against 1. c4 as black, and issues 3-6 of the Gambit Cartel give an anti-English gambit, so I think I'll read that and see what I think.
Going completely nuts as black, I even tried the Englund Gambit (1. d4 e5) yesterday. I lost two games, but not because the opening's unsound (which it probably is). In the first one, I learned some opening theory about what not to do in that opening. In the second, I actually managed to get ahead materially, but messed up the endgame.
On a similar note, I'm looking at the Elephant Gambit (1. e4 e5 2. Nf3 d5) as a way to play open games (1. e4 e5) while avoiding the typical Scotch, Italian, and Spanish lines that everyone usually plays.
I'm aware that some of these are "unsound" gambits that no grandmaster would ever touch. But at my level (~1400 USCF), just about anything's playable. I figure I can use the experience of playing odd stuff like this to get good at attacking and tactics, then switch to more normal openings when I reach the level where some of my opponents are able to beat me just because of my opening choices.
So does anyone have any comments on any of these gambits? Anyone here play them? Any other gambits you'd recommend along the same lines? Any recommendations for web sites with good info? I might even consider buying books on some of these, just to have a reference to look up lines after my games, since MCO-14 barely mentions these openings, let alone gives any real theory.
