It just doesn't make ANY sense for players having such a high skill difference at low Elo.
Everyone has good days and bad days, good games and bad games. Doesn't matter the Elo. Sometimes you see a good move, and sometimes you make a dumb mistake. Happens to everyone... even your opponents...
Same matchmaking algorithms as in other online games like FIFA or Overwatch. You'll get a few games where people play the same openings and you'll win most of them and all of a sudden there are games in a row with weird other openings and players not blundering anything while playing super fast so you lose to them. Happens ALWAYS. It's an up and down, just enough to make you stay on the site.
Why? Well to spend more time on this bullshit site and to buy the subscription. Because the site makes you feel you'll need to study everything to win the games you're currently losing to.
The system IS NOT RANDOM. It FORCES you to either win or lose. You have to outperform always the games where chesss.com puts you into a disadvantage while you can underperform in games where you have a higher chance of winning. Simple as that. It just doesn't make ANY sense for players having such a high skill difference at low Elo.
How can anyone defend such manipulative websites?
Jeez, I hate the manipulative moneymaking industry.
