New line in the king's gambit

I was wondering what you guys make of this line for black against the king's gambit. It's only been played a few times ever according to Chess.com's opening explorer and AFAIK there's no theory behind it. I will grant that in the vast majority of cases, when a line is never played, there is a reason for this. However, I've had some success with this (not saying much at my level tho) and in these variations the engine rates black as either equal or better.

In the main line here (which people have actually played against me the least, though this seems to be the way to go for white) black should easily win back the knight & play will continue. The 4. Bc4 variation is full of complications (especially when black can play Ng4), in the same spirit as many of the other king's gambit lines. LMK what you guys think!

You "SHOULD" not get this as White should not play 3.Nf3 due to 3...f5!

White should play 3.Nc3 here, which probably alters any assessment you made.

Yeah i guess 3. Nc3 is played more often but that doesn't alter my assessment of what happens if 3. Nf3 is played. Also by this logic one could just disregard hundreds of openings. For example, are all assessments of the Traxler counterattack useless just because it "SHOULD" not be played to begin with?

Well, why try to reinvent a wheel that already favors Black?  Just play 3...f5 if 3.Nf3?!.

this is a good point tbh but maybe one reason could be to throw somebody off who might be familiar with 3. ...f5 or other variations but not this

used to play more, had friends of better strength. believe we went over this line, as well as others lol. think I lost to the better player teaching me my fav opening. way it goes. think it is interesting, yet not maybe common as somewhat offbeat. like variety. cheers

Now what you are saying is that you have zero confidence in yourself being able to execute when your position is better, saying "I can't win this" and defeating yourself.  Instead, you want to play something far less promising in the Hope's that your opponent did nothing but memorize moves and does not actually understand what they are doing.  Taking this defeatist attitude towards chess will never make you better, which should be your goal.

Quit focusing on your opponent and focus on yourself.  The only focus you should ever have on your opponent is during the game, figuring out and understanding what he is threatening or planning to do based on his latest moves.

I will never suggest moves or lines that serve no purpose other than trickery where if they do not "fall for it", your position is simply bad!

The only traps I encourage people to know are the ones to avoid (like the loss of the Queen from grabbing the pawn too early in the Milner-Barry Gambit as Black) and the ones that happen to be available in the main lines, like in the Ponziani, after 1.e4 e5 2.Nf3 Nc6 3.c3 Nf6 4.d4 Nxe4 5.d5 Ne7 6.Nxe5, white has played the best moves for this opening, and now 6...d6 would be a blunder and drops at minimum a pawn, but there is even a line where White wins with an under promotion on move 11, but if it required a bad move to set up this trap, it is not even worth knowing the trap as White because you would have to play junk to get there, but this one trap in the Ponziani is worth knowing because it arises from the main line.

Long story short, quit trying to reinvent the wheel worrying about your opponent knowing something and focus more on yourself playing better chess!

It is just like poker.  You don't bluff when you already have the better hand!  You suck them in, not try to push them out!  You encourage the bad line for them, even if they "know it".
