Anyone can lose!!!
What do you feel when you lose against a VERY low rated player?

AIM-Acemove - sometimes the opposite is true too: you MADE your rating record playing two or three opponents who are convenient or transparent to you - they fall into your favorite opening schemes, etc. - but then you gradually fall back 100 points - it was nice up there...

Well, I going to see his profile, maybe he played very few games... Else, I feel sad, and often I choose to leave lichess for a day. :)
i accept the beauty and power of chess
When he is a player stronger than me, yeah, I'm happy to admire the genius of his strategic plan.

A weaker player than you can still be stronger than you on that one game (or several) that you lost.
It's not enough to be a good player - you also need to play well :-)

300-400 points lower rated players then you are NO WAY going to win. I lost to a 1100 rated guy- 300 lower than me. He played positionally solid! His all rating were <1300.
I never suspect anyone cheats except when I look at their games. He was not a cheater. And I was completely a loser.
I just lost to someone 700 rated lower than me in bullet. Im 1450 in bullet and he was 703. Tbf, I was lagging for 20 seconds and I had a really bad mouseslip lol
I would really want to say that i am playing the board, no matter rating and that we are not robots and can lose to 500 hundreds points and that will be not big problem, but this is simply not the true. I spend too much time on chess so i could not really control myself and probably will break something even if my opponent is just 150 points lower rated than me and i feel he is really bad but and overrated but i still managed to lose in a rated game. But there are a lot of sandbagging players. I see a lot of players with max rating for example 2209 and have wins vs 2250~ but his level is around 2100 but with current rating of 1915 for example. I am not saying their rating is that low on purpose, sometiems at high level you just play 20 or 30 games vs one player only and you are in tilt mode and he just made your rating low...
