The Bird!
I ran across this as I was (and still am) developing my Black game lines. For those who don't know "flipping the bird" involves the use of the middle finger at someone so I kind of wondered how this got named.
It turns out the naming isn't quite so humorous as it's named after an early Master who made this popular back in the early 1800's, Henry Bird.
The Bird is actually a White Line that is a bit off-beat because it doesn't start with either of 1.e4 or 1.d4, which is why I found it. I was looking for what else I might face if I were playing Black.
The Bird starts with 1.f4, the idea being to control the e5 square and push black away from that part of the board right from the start. It only sort of works because it appears that the most effective Black move is 1.e5 as the start to what's called the From's Gambit. Here is a simplified version of the gambit. You might like to flip the board around to see it from the Black point of view because the Gambit is with the Black pieces.
If White completely bites on the Gambit it's an elegant 6 move win for Black, so it's not a wonder that I like it. It's one of my Chess Gems for relatively new players to look for short, easy to remember game lines that can get a quick win.
Here is a video of a game where White didn't completely bite on the Gambit, but Black played very similar moves for a 12 move win. As I said, it's not a wonder I like this idea. Short, Sharp, and Shocked with almost no theory and a quick win for Black. Exactly what I was looking for.
Maybe I need to rename this post From's Gambit?
If White completely declines the gambit, you'll have a fight on your hands. I recently finished a game where exactly that happened. Right up front, White played The Bird. I giggled and pushed out the From's Gambit. Then my opponent giggled and walked right past it.
Then the fight was on and even though my opponent blundered a Rook, it was a long game. I made several blunders of my own and it's no wonder I often say I HATE PLAYING BLACK!!!
I'm not going to annotate this one because I have a couple of other games on my schedule including an OTB game against a real life friend who has been playing for around 30 years, compared to my 2 years, but I'll link to the game if anyone want to see how it went.
I did finally win by resignation; https://www.chess.com/game/daily/611920781.
