How to Improve in blitz
@5
The thread title says blitz.
Yes, improvement comes from analysing lost games.
Blitz is not worth analysis. It is pointless to analyse a 5 minute game for 5 hours.
To improve at blitz, first improve at rapid/classical and then try the same faster.
1. You can't
2. You get stuck at an elo and you cannot increase it
3. Chess.com is doing this so you can play on their app longer aka make more money
