Is there any chance that a 1100 rated player can beat a 2500+ rated player?

The formula fails to match real world results when the rating difference is as large as ~400. This has been documented and people have suggested various fixes.

There's a chance I beat Usain Bolt in the 100m because he's only human. He could have a sudden heart attack or trip and break something.

But bizarre random misfortune is not really in the spirit of the question is it? If we add to "both players want to win" with "both players are in good form, focused, motivated, and nothing bizarre like a heart attack happens" then the chance of the 1100 winning is 0%.

A random move machine has a chance because it's possible to accidentally play perfect moves, but a 1100 is forced by their knowledge and experience and calculation to play bad moves. That's why they can't win.

Maybe in a 30 sec game or smth

Depends. Back then I was still 1100 elo I once beat my girlfriend who was 2200 elo. Above 900 obvious blunders start declining and its possible for a player to go through a game without blunders at all,. If the timing of the game is short enough potentially you can hold out till timeout or if you're really lucky well everyone blunders.

I once beat someone 500 points higher in a rare fluke...but I am under no illusions. It was exactly that - a rare fluke. 1100 vs 2500 would require either the rarest of anomalies or a massive blunder.

google 'elo win probability calculator'.

the chance of an 1100 beating a 2500 is 1 in 3800.

if you played 10 games a day, it would take you a year and a month to have a game where just by random chance the 2500 player had multiple blunders in a row. it's not good odds.

"Is there any chance that a 1100 rated player can beat a 2500+ rated player?"

Only in Russia, where little girls can beat GMs:

If someone's level is X, the probabilty of winning or loosing against the level Y oppent is an exception. One occurence is nothing by default. What is the expectation? Releasing hormones?

as a 700 i once beat a 2000 in 1 minute bullet... mind you i was about 1450 rapid at the time...

That was a fun game.

But the girl was completely lost. The gentleman had mate in 1 on her at one point, then he smiled and decided to hang his queen, instead.

He lost on purpose to be kind to her.

I do the same thing with my 8-year-old son - I hang my pieces on purpose and act shocked and upset when he captures them.

It's all part of encouraging the love of the game. (Although it's also important to teach beginners to be okay with losing, too ...)

Yes, congrats. Playing against time limitation is also resulting an another question I think.
Some people is good at real time strategy games, some are good at turn based strategy games.
What my point is, other than chess, in general, as a beginner, I cannot beat Mike Tyson or any person who is doing his job for long time. It is not the low level player success, it is a sign of high level has a problem at that time. If it occurs rarely.
My rapid level is around 1000 in lichess, below 700 in 1 min bullet, 1300 in puzzles, now I am playing against 1800 level with 24 hours each turn, because i have too much thinking time, I feel good.
If I win, will it change anything? No. For me, the average level, default level is worth. Because only the defaults are continuous. On every topic. Loosing weight, doing any job. This is my opinion.
Only, limited time like parameters can make some changes.

About a 1 in 500 trillion

Bullet doesn't count. There are plenty of high rated bullet players (around 2000) who are only 1500-1700 rated in blitz and rapid which means that they are not good chess players and rather just fast. Therefore if they encounter some lag or something that decreases the speed they can play at they are beatable by people rated 1500 in rapid.

I wonder was she really 2200 strength or just...'women's 2200'.

Does she play in female only events a lot?

bro if u are 2200 you will play like a 2200 regardless of you who are

If they try really hard ig

hit his head repeatedly with a giant stick. he will fall unconscious and then his time will run out. This is the best method.

Hahahahaha, your a true comedian!

It was so funny I forgot to laugh
Keep up the good work!
