I get really annoyed when I want to play a 30-minute game and my opponent basically plays speed chess, taking like 5-10 seconds for each move like there's no tomorrow. (And often they still beat me!) I still take my time for my moves, but it's like they're trying to show off. It's so obnoxious.
Why do people do this?
In some cases, your opponents play fast and think of their subsequent moves ahead on your time while you slowly calculate moves. In other words, they actually calculate moves, but not using their time.
Strange that the account @PizzaMitKnoblauch lasted for 3 days.
Usually the dumb troll closes his new account faster.
