how to get out of the 200s

Most 200s players fall in these categories of players:

• The guy who is so good who doesn't belong on 200s
• The guy who thinks you are hacking when you premove
• The guy who resigns immediately
• The guy who blunders his queen and does not notice
• The guy who offers draws when there is checkmate in about 2 moves
• The guy who stalls you when they lose their queen and wastes 5 minutes of your life
• The guy who stalls you when you are about to checkmate them
• The guy who offers draw for no reason
• The guy who resigns when their bishop or night gets trapped
• The guy who belongs in 100s
• And the guy who tries the 4-move checkmate (or scholar's mate  or whatever you call it)

It is not that fun to play here

After they move, check to see if you can win something.

Before you move, imagine your intended move as if it's been made, and check whether it loses something.

In general, try not to lose any piece for free... not even a single pawn.

I do gambits in chess like the King's gambit

So my advice is what I wrote in post #2.

If you want that in more detail, then you can read this:

But if you don't want to listen to advice, then don't ask in the first place

(Don't play the king's gambit. First you need to learn greed, do your best to not lose anything, not even a single pawn. That's the first step.)

That's a good way of thinking about it... try to understand why the blunder was made, then come up with a plan on how to avoid doing it in future games.

So sure, not premoving will probably help.

The more you go through this process the better you'll get

identify mistakes -> think about why they happened -> make a plan on how you'll do it differently in the future

On the other hand, there's a lot of chess experience to gain by playing the Scholar's mate. Both the traditional one, and the early Parnham attack.
