How to get better at blitz?

Well if you hadn't, your rating would be 3100.  I bet you wish you hadn't wasted your time playing bullet now.

I disagree, blitz is a good training tool

You're a 15 year old IM though.  I don't think you understand how most people play and study chess, and especially how they improve.

For example having years between reading a chess book, or going to a tournament.  Never having a coach.  Never analyzing your own games.  Things like this.

Another way to say it, if people decided to copy you, blitz probably ranks near the bottom in importance.

I hate tactics trainer. Even when I find winning continuations it gives me no points just because it isn't "the best" even if it still wins.

I already play more long chess, that's how I got to Class A finally. I just am terrible at finding those forcing continuations.

That's exactly why you should be training tactics, it doesn't need to be on this site tough.(If you're that annoyed about the score system, however chances are your winning continuation is not really winning)

When I first came to this site, those problems seemed to be worse. In recent times, I have noticed that if you don't play the best, it either loses right away, leaves you down significant material or you end up having to play a position that is equal and tedious.

I blundered away a winning position today OTB against an expert in time trouble, this is really getting annoying :(

Are you me?

I don't think so..

Join the club guys, I missed a forced mate against a stronger play and now I can't avoid a forced draw...

blitz is the crack cocaine of chess

Play faster!

That's bullet. Blitz is more like espresso.

Make the blitz!

Make better moves fast.
