If anything choosing an inferior opening would help someone's chess improvement because you have to be more precise, and you're forced to use all your middlegame and endgame technique to win. But the Budapest isn't even inferior I feel, just very underestimated and underrated.
I know that you personally Ponz are at that highest level where opening choice matters a great deal, for a amatuer like me, I haven't even read Dvoretsky's Endgame Manual yet. I'd rather spend my chess study time reading that book than studying a new opening, even though doing so would mean sticking with the Budapest and stymying my chess development as you indicate it will.
In the 5 months i've played the Budapest, i realized if you really want to get to at least National Master, you have to play more solid and respected openings becuase when you start to come across players over 2000, if they know what their doing ... i had to switch to a more popular alternative, the Leningrad Dutch which grants Black more piece activity most times. so in conclusion i would not play the Budapest Gambit as your main unless you want to stay a class B player your whole life. Thats just my advice
It's commonly known that opening choice doesn't hinder improvement, really? I disagree. If someone plays a Black opening which gives him worse than normal as Black he will never rise above expert. It is ok to play such openings if you do not want to improve your chess above a certain level.
it's switching openings all the time does. This does also but that does not mean it is good to choose an inferior opening.
I see from your recent thread that you're already thinking of giving up on the Dutch. Are you just going to keep switching openings whenver you read people (most of whom have no clue what they're talking about) saying your opening is bad? You are making assumptions here.
Well ok, I'll keep playing the Budapest so I won't have to constantly keep learning opening theory, and you keep switching openings, and we'll see which one of us gets past class B level first. Who cares which of you get to class A first?
By the way, White gets an advantage out of most openings. So if you're looking for a Black opening that can get an objective advantage I imagine you'll be stuck in your revolving door of new openings forever. This is kind of a strawman argument. Very few players are so weak as to think there is an opening for Black which actually should give him an advantage. Exception, there are lines vs 1. e4 e5 2. f4 exf4 3. Nf3 which give Black an advantage.
The Budapest is very underrated. Perhaps the reason why is that d4 c4 players don't like it. They'll say it's bad and that it sucks, but at the same time most of them don't like to see it. Maybe low rated players who have not studied a line against the Budapest do not like to see it.
They have a kind of condescension and animosity towards it. I think because it gives an 1.e4 flavor to the game, like say in the Adler variation 4...Bc5, this move is great, how many times do you get to hit f2 out of the opening against 1.d4? Of course we don't expect to actually capture f2, it's just a psychological bonus that we're making them play e3. Oh, wow! I have to play e3! Oh horrors!
You see, a lot of d4 c4 players are control freaks, they're trying to get away from 1.e4, we're dragging them back into it and forcing the game into paths of our choosing.
Lots of laughs, d4, c4 players are control freaks???
