Not allowing beginner players to play the game is stupid!
Blitz ( under 10 min) is not a welcoming format for anyone who want to learn under 1200.
Wanna hear a funny story?
Last year I was 700 blitz 800 rapid and b9/8 for my chess team if I am correct
I played blitz, 1000 rapid, 1100 blitz, and dominated b6/7 for most of the season
So yes, blitz does help
No one said or think that blitz doesn't help! even taking a nap help or eating help and getting in shape help!
We were talking about optimizing the improvement for beginners!
I saw here players with thousands of blitz games and still at 850...and asking why they didn't improve...
