what opening should i play as a 800 beginner?

Play 1. e4, and then maybe a gambit...

ikr ikr. Well I do think e5 is better for beginners but Najdorf is completely fine if you want to play it

French. Can’t get Scholar’s Mated with a pawn on e6. Besides that surprisingly useful point, it’s also an incredibly solid opening with a lot of teaching opportunities for a new chess player.

You should probably watch hanging pawns on YouTube then

I’ve been doing well with the Najdorf lol

As someone who is near 800 ELO and struggling with the black pieces, I went through some of your games and have to say that you are pretty much crushing it with the Nimzo-Indian and the Sicilian Najdorf. I just wanted to inquire if the Caro-Kann is a solid answer to 1.e4 or should I try out the Open Sicilian? Have a nice day.

The Caro-Kann is great. It’s very solid, simple to play, and you have options based on your style. If you’re willing to learn the theory associated with the Open Sicilian, definitely try it. It’s one of white’s best fighting options against the Sicilian, if not THE best. Have a good day.

Thanks for the suggestion. I tried out the Caro-Kann and the Open Sicilian(everything except the Najdorf) and realized that the Open Sicilian does take the opponent by surprise but I find it a bit tough to convert an advantage into a win with that opening while the Caro does churn out a better result for me overall. Maybe it has something to do with me being a bit better in positional play than in tactical ideas. Thanks for helping me out and have a nice day.

Thank you for trying my recommendations! If not the Open, you might consider trying the Closed Sicilian, a somewhat positional line.

I did. The opening videos I’ve seen sometimes have errors made and sometimes I feel aren’t sufficiently explained. It’s alright but like, meh there’s better stuff out there and it might not be so reliable. Also I feel his opening stuff isn’t as engaging as other chess channels. But I do like him and I wish him best on his chess journey.

His idea of learning to play chess is to explain it to other people, and that’s what he’s doing. But I wouldn’t use him as my number one source of opening info

I find his advice reasonable, clear, and straight to the point. But you’re allowed to have an opinion.

You are as well. 
Just know that the videos might not be the most reliable.

It depends on your style, but you might want to consider gambits. They will help you learn to attack and your opponents won't be able to exploit it if they are slightly unsound.

This is bad advice. Gambits (unsound, “true” gambits, ones which usually play for early checkmate or the win of a piece) won’t help you learn how to attack effectively, as it’s essentially the same exact attack every time in a “true” gambit.
Much better for learning how to attack is an aggressive, nuanced opening, such as the Poisoned Pawn Winawer, the Four Pawns KID or Four Pawns Alekhine’s, the Meran Semi-Slav, and the Botvinnik Semi-Slav. 
If you want to play a gambit, a good, solid gambit, there are only three I’ll recommend in good faith: The Evans Gambit of the Giuoco Piano, the Marshall Attack of the Ruy Lopez, and the Benko/Blumenfeld Gambit family. The Jaenisch of the Ruy Lopez gets an honorary mention for almost being a reasonable opening but it just loses in spectacular fashion to anyone who’s taken 10 minutes previously to study it.

And the Queen’s Gambit

Yeah, I suppose, but I’m talking the vicious, bloody, double-edged openings where GMs get slaughtered in world championships. Queen’s Gambit isn’t even all too aggressive, it’s actually quite positional. You’re not wrong, there are tactics aplenty for both sides, but compare a Four Pawns Alekhine to a QGD and you can see the difference in raw aggression from Black more clearly. Or like a Poisoned Pawn Najdorf to a Chebanenko Slav.

“If you want to play a gambit, a good, solid, gambit, there are only three I’ll recommend in good faith:”

Italian Game.

Why would it need to be a solid gambit at the 800 level?

Queen’s Gambit’s a misnomer. White wins the pawn back by force, so like the Scandinavian, it’s just an exchange.
