Also I'm sorry to insult most people here but 1800s are noobs
The difference between 1800s and 2500s are like the difference between a toddler and Usain Bolt in a 100m run
so is the difference between a new black belt and an adcc champion.. its not a crazy comparison
You're not aware of it tho
are you reading the thing you sent LMAO. 2 is standard but can easily be one or less. 1800 on chess.com might be a noob to you but that doesnt change its better than the vast vast majority of people... kinda like a black belt
