The Grob is bad. Don’t play it. And it is a very bad idea to just play for tricks and traps. If you actually want to achieve 1800+ you’re going to have to learn to play real strategic chess. Here, you are simply asking for a more advanced version of the 4-move checkmate.
Good openings to play against 1400-1700 in blitz.

@Fizzyband Okay, that's fine. So I'll rename it to "Openings to play against 1400-1700 in blitz". So, what do you think is a good opening @Fizzyband?

These tricks don't work.
This is a wrong trap and u can find how can black refute this on chess.com forum, we already mentioned many times here.
The thing is : good openings against 1400-1700 are the same against any level!
Just play good moves and u will get the reward, no need to play only for tricks and traps...
A good opening is an opening playing for quick development, controling centre, avoiding to weaken your position.
g4 is just weakness for king's side so u can play it for fun but no more...

Thanks @poucin... Could you give me an example? I play Ruy Lopez as White and Caro-Kann/King's Indian as black. I want to shift over to more positional, quiet lines. Maybe we can fill in some action too
Hey guys, I just wanted to know what openings would be best to play against 1400-1700s because I'm trying to boost my rating to 1700-1800 and i am almost 1400.
If you guys could give me some tips, that would be awesome!
In you giving me tips, I'll give you a tricky opening theory (with my best annotations).
