How is it that the 1200 bot played at 750?

I've only been playing about three months and have stuck to the computer opponents to save time and bypass cheaters. When I played the 2700 it said I played at 1550 (which I can't), but more interestingly when I just won decisively against the 1200 bot it said the bot played at 750. If the bot is designed to play at a certain level, how can it play at such a lower level?

Making a computer to play at a precise strength is not really possible.

The estimated ratings are often completely inaccurate.

Getting a computer to make blunders the way humans do is not easy.

Thank you. That makes sense.
Should I assume that the estimated rating for my play or the computers is also fairly inaccurate?
I would like to gauge my improvement over time - is playing against real people the only way?

Playing real people is the only real way, as the concept of elo is your playing strength relative to the player pool… you can only find it by playing lots of games!

There's nothing wrong with bots, they are great for training (1500 and higher).

What do you use to play them? Tablet? Phone? You have to play on desktop with modern CPU, with AVX2 support. Chess engines are even more demanding than video games, and these bots run on your CPU in real time. On lichess they run on server CPUs, but if you loose internet connection the game is lost.

Here's a detailed explanation:

I don't know what AVX2 support is, but I play on a nice PC with a 26' monitor. I use my phone for very little. I'm not hugely worried about losing internet.
The computer always moves in a few seconds - which is rather startling as it gives the impression of playing a much better player. I'm surprised at the adrenaline rushes I sometimes get.

That's good. CPU matters, not monitor.

I see that Ding Liren crushed you in 22 moves with 95.6 accuracy. Perfectly normal. That means your PC is probably finehappy.png

Try stronger bots, over 1500. They are much better. Lower ones are useless for traininghappy.png
