What are best chess openings to use?

the halloween gambit is pretty good, it also has a reverse version.

There is no "best", simply a FINITE number of good openings, and the Halloween Gambit ain't one of them!

I ask that you reconsider, the halloween gambit not only makes black completely docile, but also allots near full control of the center for white.

I do agree with you about "good openings".

perhaps but it does give you good advantage in the long run.

I also play Correspondence on ICCF, the granddaddy of correspondence. It requires very deep theoretical knowledge and thought. The Halloween Gambit is complete trash! The fact that you can weasel out some cheap shot trick on a 1200 player doesn't mean jack squat.

The Halloween Gambit is UTTER TRASH!

That is your opinion, and I respect it, though i do not share it.

It's fact, not opinion. It is completely unsound. The difference between +0.3 and +0.5 is nominal, and a different bot would give the first one +0.5 and the second one +0.3. Means nothing.

But when you start getting above one-and-a-half, it means something! In the Halloween Gambit, Stockist 16 gives White's best move as 5.d4 with an assessment of -1.69! It is not sound at all!

The Halloween gambit depends on the time control and strength of players. In online chess against the vast majority of players, the Halloween gambit is nice. Lichess statistics across all ratings and time controls show win rates of 53% white, 3% draw, 44% black. Even if you filter it to ratings 2000+, and ignore bullet time controls, the Halloween gambit still scores 51% white, 5% draw, 44% black - a perfectly good score.

This is true of most gambits. They score very well online, even though engines say they're crap, because - surprise - we humans aren't engines! Engines won't show the concept of a position that's numerically winning but really hard to play accurately.

That being said, in classical time controls against strong opponents, the Halloween gambit is not good. It's the epitome of "hope chess", where white just has to hope that black makes a mistake, and that's far less likely to happen with lots of time on the clock. I watched this gambit in a tournament game just a few days ago, between two 1800s with 2 hours per player, and black won fairly quickly. Black made a few key defensive moves and White was hopeless after that.

Thank you for pointing that out to me.

I would come up with a good arguement but im only 500 elo.

And yet you put up post 9 as a 506 arguing against a 2147!

SMH!

Definitely the Grob/Borg. 1. g4 d5 for white or 1. d4 g5 for black

The best openings for you are the ones you understand.

I prefer to play the queen's gambit and the Sicilian. Sometimes I'll play the Lundon gambit when I want to have fun, even though it is unsound.

Just because im 500 elo does not mean im not good at chess.

Something tells me you don’t exactly understand the concept of ELO… I can’t figure out what it is though.
