I drawed against a 2100 rating bot. I made one mistake that made it a draw.
I defeated a 2100-rated bot with 99% accuracy

"Here's some proof that I did not use an engine"... yeah, we know what bot you payed against, but how is that proof that you didn't use an engine?

@KieferSmith, Oscar has 3 crowns, and if you have ever played against a chess bot, you can change the settings to change the time, have stockfish help you, etc. If you use stockfish, you will get one crown(just like in some game with stars, the amount of stars(3 meaning very good, 2 meaning average and one meaning bad) determine how good you play. it's the same with crowns, except it depends on whether you cheat or not.) If you use stockfish to help you only on some parts of the game, you'll get two. If you win the game against the bot all by yourself with zero help, you'll get three crowns. (This only applies to games against the computer.) Hope this helps!
Just the other day, I managed to defeat a 2100-rated bot (specifically Oscar-Bot) in a 10-minute game with near-perfect accuracy that was 50+ moves long If you want to see the game, the link to it is here: My Victory Against Chess.com's Oscar-Bot (2100) - 99% Accuracy - YouTube.
Here's some verification that I did not use an engine in the game:
