Who has heard of the Colorado Gambit in the Nimzowitsch defense? Well...

I watched that introduction video. Discussion of the Colorado Gambit (even if it is misnamed) starts at 33:50. The line I gave is from ChessExplained's "Keep It Simple: 1 e4" repertoire on chessable, which I recommend highly. That's the only line he gives against the Colorado Gambit, there are a few places where black could deviate of course. Notably 8... Ncxe5 instead of Ndxe5, and there are move 10 alternatives. 5... Bd7 or 5... a6 are possible alternatives to 5... Qd6.
I'd never faced this gambit before because I used to play 2 d4 against the Nimzovitch, but the aforementioned repertoire suggests 2 Nf3 offering to transpose back to normal 1 e4 e5 2 Nf3 Nc6 lines. So a day after studying this line I got it over the board. I screwed up the move order though, playing 7 Bf4 when I was supposed to castle first, and later blundered an exchange. Not exactly a masterpiece here, but this was the game.

i wish it worked but sadly it is positionally busted.the lines with bb5 are the most critical but even if white goes for a normal plan, it leads to a bad position.
and now what?
7...e6 8.re1 qd7 9.qe2 and there goes the e-pawn.
7...qd7 8ne5! qd6 9.re1 and black cant 0-0-0 because of nf7
7...g6 8.re1 bg7 9.ng5
7...qd6 8.re1 0-0-0 ng5 or 8...g6 9.nc3 a6 10.ng5.
also, if black goes 5.bg5, then 6.h3 bxf3 7.qxf3 Nxd4? 8.qh5+! (best is probably just 8.nf6 where black is JUST holding on) or 6...bh5 7.g4 bf7 8.c3 and black just looks silly.
any strong player can figure these moves out.
...I have created a new line in it. I call it...
