The worst chess platform, corporate funded hacks, they manipulate the timer in favor of the opponents, they give 5 minutes extra to the opponent in a fixed 1 minute match, his timer never becomes zero while your timer goes down steadily, they put you against a player of very high rating and don't let you abort the match, they start flashing that "Internet is not connecting" and the game gets abandoned automatically, but the internet works perfectly. Sometimes timer screen doesn't appear for 10 seconds and it results in a guaranteed loss in a 1 minute match, even loss of 5 seconds is disastrous in a 1 minute match. Lichess is 100 times better.
